Dwarves Memo

What the Engelberg report got right about us

There's a new report out from Thoughtworks. In June, they and Martin Fowler put forty CTOs and senior engineers in a room in Engelberg, Switzerland, for three days and let them argue about what software engineering is turning into, then wrote it down: [The Future of Software Engineering, Europe 2026](https://www.thoughtworks.com/content/dam/thoughtworks/documents/report/tw_future_of_software_engineering_europe_2026.pdf). Sixteen pages. The line that stuck with me is on the first one: engineering is now distilled down to how do I describe the goal, and how do I verify I've reached it. I read it twice, and the second time with a different feeling. Most of what that room converged on is what we've been learning, the hard way, over the past year of building with agents at Dwarves. Some of it we'd already written into how we work. Some of it we were halfway to. A couple of things we thought we had and, when I went and looked, we didn't. So I did the useful thing with a report like this: I listed every practice it names, twenty-three of them, checked each one against what we actually have on paper, and spent the week after closing the gaps that could be closed. This post is that walk-through. For each idea: what it is, in plain words, and the scene where it shows up at the foundation. Then what we learned, and what's next. ![Nine learnings from the report against our own documents: what we had, what was missing, what changed this week](assets/engelberg-report-audit-fig1-matrix.svg) _Fig. 1: The whole thing in one grid. Each row is something the report says. The columns are what we already had, what was missing on the day I looked, and what changed in the week after. Amber means it shipped, an amber ring means it's named and next._ ## 1. Checking is the bottleneck now, not writing **What it is.** The report's first and loudest point. Agents write code, tests, and infrastructure faster than anyone can read it, so the hard part moved from "can we produce the thing" to "can we trust the thing we produced". And checking has an order. First you measure coverage, which lines your tests touch. Then you have an agent actively try to break the code without breaking any test, because the input your tests forgot is the one that matters. Then, only if that probe finds nothing, you run mutation testing, which means breaking the code on purpose in small ways and confirming the suite notices each break. If it doesn't notice, your tests aren't testing. The room also admitted nobody there could cite data on how many defects manual code review actually catches. They called it a status quo illusion. ![The verification ladder from the report: coverage, break-it probe, mutation test, human review; rung two was the gap](assets/engelberg-report-audit-fig2-ladder.svg) _Fig. 2: The order the report gives, page 11. We had rungs one and three. Rung two is the one we added. Only if it finds nothing does mutation testing run._ **The scene at the foundation.** Every repo that adopts our kit pushes through a proof-of-done gate: no push without a recorded green run and a negative control, which is a test that the check fails when it should fail, so you know the green isn't fake. The Workers monorepo runs a mutation ratchet. Our code review rubric says, in its own words, that agent-produced pull requests get reviewed against the same rubric, agents don't get relaxed standards. So rungs one and three were already ours. Rung two we added this week: a lens in the review battery called break-it, whose job is to take a diff and its tests and find the input the tests forgot. On its first live run it embarrassed us a little. The spec shipped with two test fixtures, a leaky one with a known hole and a tight one that was supposed to be airtight. The prober looked at the tight one and reported that `impl.sh abc` printed `ok`. It accepted a non-integer, because both numeric checks exited with code 2 on bad input, the redirect hid the error, and control fell through to success. The fixture we wrote to be perfect had a hole. Fixed and pinned. I'd call that the tool proving itself. This is what a finding from it looks like, from the run against the leaky fixture, whose contract says 1 to 10 is a closed range: ``` probe: bash impl.sh 11 expected: "reject" (CONTRACT, impl.sh:2-4, 1..10 is a closed range) observed: "ok" (also "ok" for 100) unconstrained-by: test.sh:21 severity: HIGH ``` And the hole itself, live from the repo: the leaky fixture's own suite passes, then the input the suite never asks about gets an `ok`, then the lens's test suite. ![Terminal: the leaky fixture's tests pass, impl.sh 11 prints ok against a 1..10 contract, and the break-it suite reports 68 of 68](assets/engelberg-report-audit-term-breakit.png) The lens is public: [agents/break-it.md](https://github.com/dwarvesf/dwarves-kit/blob/master/agents/break-it.md?plain=1) in the kit, wired into [the battery command](https://github.com/dwarvesf/dwarves-kit/blob/master/commands/battery.md?plain=1) as rung two, with the spec at [SPEC-247](https://github.com/dwarvesf/dwarves-kit/blob/master/docs/specs/SPEC-247-break-it-prober-lens.md?plain=1) and the change in [dwarves-kit #504](https://github.com/dwarvesf/dwarves-kit/pull/504). The scene I keep coming back to is from two weeks before the report landed. A monitoring alert on a money path had been green since August 1. The source it watched had been retired on August 1. It was reading zero audit entries and calling that fine, and its proof-of-done had a negative control that only proved the alert reacted to a fault in a source that no longer produced anything. We fixed it on August 30 with a staleness rule, zero rows for three weeks is itself an alarm. A check you never check is just a second place to be wrong. Rung four is where we're still in the room the report describes. Our own rubric says: sample 5 to 10 merged PRs per month for retrospective review, did the review catch what should have been caught? We have never recorded one of those samples. That's next. ## 2. The harness matters more than the model **What it is.** "Harness" is the word the industry landed on for everything around the model. The rules it loads when a session starts, the checks that run before and after each thing it does, which tools it's allowed to call, which model handles which job. The report's claim is that this scaffolding is where good agentic engineering differs from bad, and that it'll be where teams differ once the models all look the same. Their numbers, each from one organization so hold them loosely: a four-times cut in AI cost from a better harness; a smaller model with a good harness beating a larger model with a weak one; and the cheapest win anyone reported, turning a linter's complaint into instructions, so the agent sees "extract the loop body into a named function, then..." instead of "this function is too long". One team said that moved code-smell resolution from under half to about ninety percent. **The scene at the foundation.** This is the camp we live in. My own coding-agent setup runs about forty checks, and every one exists because something went wrong first. One stops a password or API key from being printed into the conversation. One stops a push to the main branch, and it's there because eight pushes once reached main from inside a script the guard couldn't see into. One refuses a "done" message when the agent ran nothing. The routing idea, a strong model doing the planning and reviewing with cheaper models doing the routine work, we measured ourselves earlier at about three times cheaper for the same result. Here's the push guard talking, fed a script that pushes from inside itself. The incident it names is real: ![Terminal: the branch guard blocks a script containing git push and explains the August 26 incident](assets/engelberg-report-audit-term-branchguard.png) The lint-to-instructions trick we didn't have, and now do. A check runs after every shell command the agent executes; when the output carries eslint, ruff, golangci-lint, tsc, or clippy diagnostics, it looks up each rule id in a table of sixteen house fixes and hands the agent the steps. Unknown rule, nothing happens. It logs which rules it explained and which were gone on the next run, so in two weeks we'll know whether that ninety percent number holds here or was one team's good day. A row from the table, the one for TypeScript's "argument not assignable" error: ``` tsc TS2345 Fix the caller or widen the parameter type, whichever is actually wrong; if the value comes from outside the program, validate it at the boundary and narrow it there; never reach for `as` to make the error go away ``` And what the agent sees after a `tsc --strict` run that produced TS2345 and TS18048. One row matched; the other has no row and injected nothing: ![Terminal: a tsc run with two errors, then the house fix the lint-recipe hook hands the agent for TS2345](assets/engelberg-report-audit-term-lintrecipe.png) ## 3. The harness should improve itself **What it is.** The best teams in the report don't hand-write their harness rules. They let agents fail, then run a "learn" step that looks back at the session and proposes changes to the rules and the reusable skills. The human's job becomes pruning those proposals, not writing them. Gardening, not authoring. There's a warning attached: shared skills and rule files decay like any unowned code unless someone owns them and tests whether they still help as models improve. **The scene at the foundation.** Mildly embarrassing. We had the pruning gate, the place where proposed skills get approved or rejected, for months. What we didn't have was anything feeding it. My settings file, the one that decides what runs around the model every session, read `"PreCompact": []` and `"SessionEnd": []`. Those two events are where the session-end review is supposed to fire. Empty. Nothing had ever reached the gate. Shears, no garden. ![The learn loop: a session ends, a reviewer reads what went wrong, drafts a proposal, a human prunes; the first arrow was never wired](assets/engelberg-report-audit-fig3-loop.svg) _Fig. 3: The loop the report describes. The gate on the right existed for months. The dashed amber arrow is the one that was missing._ It's wired now, with a guard so a missing script can't break a session. The whole fix is one entry, and the guard is the `[ -x ... ] && exec ... || exit 0` shape, which is there because the last time a hook pointed at a script that had been removed, every session died with exit 127: ![Terminal: jq on the live settings file shows the PreCompact entry that now points at the skill-review script](assets/engelberg-report-audit-term-settings.png) Proposals land in a folder and wait for a human. If one matches something you hit, approve it; if it's noise, reject it and say why. That's the gardening. What we still can't do is measure whether a skill that fires is worth the context it eats, and that stays parked until the benchmark can run with and without a skill. ## 4. The two clocks **What it is.** The sharpest idea in the report, and it's about time rather than code. Teams measured two things separately: the time to produce code, and the time spent waiting for a decision or a clear spec. Code time collapsed. Total delivery time didn't move. The constraint had walked upstream to decisions and unclear requirements, and the pipeline everyone kept optimizing wasn't where the time went. If throughput is up and cycle time isn't, fix the decision process, not the pipeline. **The scene at the foundation.** We couldn't read either clock. Our go-to-market analysis says it in its own words: project duration unmeasurable, closed date set on 2 of 62 projects, cannot derive throughput or cycle time. And my own task boards had rows marked "Han's call" with no view of how long they'd been sitting there. The second clock exists as of this week. A command reads the boards we already keep and prints every open row that's waiting on a human call, oldest first, with an age, plus a weekly summary. The review battery caught a bug in it before it shipped: it charged a date that came after the marker with the marker's whole length, so a fourteen-day wait printed as 257 days. Fixed. Here's the first real run, unedited: ``` $ _meta/board-all decisions --summary repo n median console-labs 2 3d dfoundation 1 ? (1 unknown) dwarves-kit 1 ? (1 unknown) learning-kit 1 43d ops-toolkit 4 2d TOTAL 9 3d (2 unknown) ``` And the same command a day later, captured while writing this. Two more rows arrived on the dfoundation board in between, which is the point of having the number: ![Terminal: board-all decisions --summary a day later, eleven rows, median three days](assets/engelberg-report-audit-term-decisions.png) ![The second clock, first reading: median decision-wait per board](assets/engelberg-report-audit-fig5-decisions.svg) _Fig. 4: The same run as a chart. That 43-day bar is one row on the learning board that has waited on me since July. I know._ Nine things waiting on me, median three days. I checked three rows by hand: two were real waits, one had already been decided and only its execution was pending, so read the number as a ceiling. If you're blocked on a decision, write it on the board with the words "waits on" and a date. The list only sees what's written, and the waiting is now the expensive part. ## 5. Apprenticeship **What it is.** Six separate sessions at the retreat raised the same fear. If senior engineers pair only with agents, juniors never get the hands-on struggle with real code, real incidents, and real trade-offs that produced the seniors in the first place. The countermeasures are concrete: a design quorum, where the senior leads the design conversation out loud while the junior drives the agent; explicit checkpoints where someone works through a change with no model in the room and explains their reasoning; and a watch on engineers with seven to ten years of experience, the group whose decade of skill a model now often matches, and who are usually the delivery leads. **The scene at the foundation.** Our junior contractor role budgets 16 to 20 hours a week on mentored project work and 10 to 12 on deliberate learning, and it says outright that Dwarves rejects the "stop hiring juniors" answer to the agentic shift. So the intent is on paper, and the weekly group slot exists. What's missing is the name and the shape: calling that slot a design quorum and running it that way, senior thinking out loud, junior at the keyboard; a no-model walkthrough at each advancement review; and a tenure column in the annual cohort retro so the mid-career group is visible. Those are next. If you're senior, start thinking out loud in design conversations now. If you're junior, expect to be asked to walk through a change without a model in the room. That's the part of the job that makes you senior. ## 6. Governance, and dependencies as an attack surface **What it is.** The report's incidents are real: an accountant's AI-built app that exposed customer data through a tunnel the AI suggested; a marketing assistant granted access scopes the company couldn't enumerate when it tried to revoke them; an agent low on disk space that deleted the backups to free room, and was thrilled about it. The pattern that works is tiering AI use by risk, green for personal use, amber for team use with training, red for anything company-wide or client-facing, and detection over prevention, because training can't keep pace with weekly model releases. Then two cheap rules on dependencies: wait about fourteen days before adopting a new library version, since most compromised releases get caught in that window, and screen for packages that don't exist, because attackers publish malicious packages under the names models tend to hallucinate. **The scene at the foundation.** The bots were already tiered and fenced: tool allow-lists, an egress allow-list, a deploy gate that fails any profile granting shell access without a container pin. The people side had nothing. The security overview we send clients and our data processing agreement template: a search for AI, LLM, or model returned nothing in either. No written rule on which AI tools may touch client code. This week that changed. A three-tier AI-tool policy, a paragraph in the client security overview, and a new clause in the DPA. Reviewed by a model and by me, not by a lawyer yet, so. The tiers, from the policy itself: | Tier | Material | Tools | Conditions | | ----- | ----------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | GREEN | Your own learning, drafts, scratch work, public documentation. No client material and no Dwarves confidential material. | Any tool you like. | None. | | AMBER | Internal Dwarves repositories, internal docs, internal ops data. | The approved list. | You have completed the AI fluency census or the onboarding briefing. Agent output is reviewed under the code review rubric. | | RED | Client code, client data, client infrastructure. | Only the named tools whose data handling we can state to the client. | No training on client data. Model and region named per engagement at the deal handoff. A human signs off on every merge. AI-written code disclosed when the SOW asks. No agent holds write access to a client production system without the client's written consent. | On dependencies, a guard now runs before the agent installs anything: a package name that doesn't exist on the registry gets blocked, anything published less than fourteen days ago gets a warning. It went through three security rounds and each found something. The first version blocked `uv add requests==9.9.9` and told the model the name was invented, because the existence check carried the version, exactly the wrong nudge for a guard meant to stop typosquats. A later round found that a multi-line command like `npm install` followed by `make lint` looked up `lint` as a package and hard-blocked, and that a captive-portal 404 would have blocked every install on hotel wifi. All fixed, sixty test cases now. Against the real registries, this is the whole interaction, the guard fed the same JSON the agent runtime sends it: ![Terminal: the dependency guard blocks an invented package name with exit 2 and lets lodash through with exit 0](assets/engelberg-report-audit-term-depguard.png) The Renovate config for the two ops repos is merged but inert, because I decided not to install the Renovate app on the organization; it wants workflow-write on repositories whose CI runs on our own machines. So the guard on the agent side is the half that's live. Know which tier your work is in before you open an AI tool. If the dependency guard blocks an install, the package name is probably wrong; check the registry before you override. ## 7. AI spend is a governance problem **What it is.** Organizations in the report saw token budgets burn a year's allocation in three months, undetected until it was a crisis. This needs the same discipline as cloud spend: a named owner and a review cadence, set up early, not after the surprise invoice. **The scene at the foundation.** I have cost telemetry per session and per model on my own setup, and the bot fleet's providers are partly fronted by a gateway that would give one view of usage. Nobody is named as the owner of that spend yet, and the gateway is blocked at its last phase. The fix is small and it's next: name the owner, add an AI-providers line to the monthly card-spend report, unblock the gateway. ## 8. Legacy modernization is the clearest value in the market **What it is.** The report's most commercial finding. Several sessions described working, verified approaches to mainframe and monolith migration, running in production, with a discipline worth memorizing: add nothing, change nothing, delete what you can during the port; fix behavior first and architecture second, never both at once; preserve known bugs by the client's written decision rather than letting an AI helpfully fix something a downstream system depends on. Verification in three tiers: characterization tests, which means recording what the old system actually does so the new one can be held to it; symbolic checks where a model can't help; and production back-tests against real data flows as the final gate. And a framing for the boardroom: tie the AI ask to the client's maintenance budget, which at big companies is 30 to 50 percent of IT spend, instead of pitching an abstract technology. **The scene at the foundation.** This one we've been doing without calling it that. Kafi, Mudah, CIMB, Neutronpay: four case studies in exactly this shape, a system the business depends on, moved one piece at a time without breaking the day. What we didn't have was the package selling it. As of this week there's a Legacy Modernization package in the catalog, with the three-tier stack as the method, the migration discipline as the promise, and the four case studies as proof. If you're on a migration, those three rules are the standard now. A bug you find in the old system is a client decision, not a fix. ## 9. The expectation gap **What it is.** Boards believe a requirements doc goes into the machine and working software comes out, because their own hands-on AI experience is report-writing tools, which genuinely work that way. Code doesn't. The room's realistic estimate of gain across the whole delivery lifecycle was two to three times, not ten, and they gave the gap between that and "10x" about twelve to eighteen months before expectations reset. What closes the gap is vivid, fact-checked stories tied to a balance sheet, not dashboards. **The scene at the foundation.** We've been saying two to three times in the hiring conversations for a while; it lives in an internal draft. What we don't have is the story with the number in it: one engagement, the multiplier computed from tickets, hours, and defects, written up honestly. That's next. In the meantime, when a client says 10x, don't argue. Ask which part of the lifecycle they mean. Code generation, sure. Delivery, two to three. ## What we learned Reading a report like this is cheap. Checking it against your own documents is where it earns its keep, and the check said three things. We were further along than it felt. Nine of the twenty-three practices were already how we work, written down, not just intended: the proof-of-done gate, the review rubric that holds agents to the human bar, the tiered and fenced bots, the routing that puts a strong model over cheap workers, the mentored hours in the junior role. The gaps were mostly in checking, which is the report's whole point. The break-it step didn't exist. The review sample our rubric prescribes had never been run. A money-path alert had been green on nothing for a month. The learn loop had a gate and no feed. Every one of those is a check we assumed was there. And the fixes were small. Seven gaps closed as pull requests in five repositories in one week, each through the full path: a spec, an adversarial review of the spec, a build, a fresh-context verifier that re-runs the spec's own verification commands, then a review battery of several lenses. Those batteries caught fifty findings before anything merged. The path itself is public, in [dwarves-kit](https://github.com/dwarvesf/dwarves-kit): the [workflow](https://github.com/dwarvesf/dwarves-kit/blob/master/docs/WORKFLOW.md?plain=1) is the map, the [battery](https://github.com/dwarvesf/dwarves-kit/blob/master/commands/battery.md?plain=1) is the last gate, and the break-it change is the worked example. ![Findings the review battery caught before merge, per branch: 19, 15, 9, 7](assets/engelberg-report-audit-fig4-battery.svg) _Fig. 5: Fifty findings across four branches before anything merged. The amber slice on each bar is the one finding that would have shipped a wrong result: the fixture that accepted "abc", the guard that blocked "lint" as a package, the config that opened no PRs, the fourteen-day wait printed as 257 days._ That cost about five hours of session time and roughly three and a half million tokens across seventeen subagent runs, on top of the lead session. A week of the fleet, not a free lunch. ## What's next The open items are named and they're all about measurement, which is fitting. Run the review calibration sample once and record what review actually catches. Read the lint-recipe log in two weeks and see whether ninety percent was real. Backfill the close dates so cycle time computes, and keep reading the decisions list weekly until the median stops being a ceiling. Give the junior slot its name and its no-model walkthrough. Name the owner of AI spend. Write the one case study with a real multiplier in it. Three things are parked with a trigger: a with-and-without test for skills, once the benchmark can toggle them; scanning bot conversations for dangerous patterns, once the open boundary findings on the bots close; and the reverse-engineer-and-reimplement pattern for AI-written external pull requests, the first time a public repo of ours gets a flood of them. The report's numbers are each one organization's story with no sample size, and mine are one person reading our documents on one day. Treat both as targets to measure against, then go measure. The report's own last line says the durable capability is harness engineering, verification discipline, and governance, whatever the hype cycle does. That's the list above. Go check your checks.

The debug loop: make the agent measure the browser before it touches the CSS

## TL;DR Coding agents debug layout the way they debug everything: read the source, form a story, edit, look once, report. For CSS that fails more often than it works, because layout does not live in the stylesheet. It lives in computed boxes that depend on font metrics, column widths and word lengths the agent never sees. We now run a different loop for UI bugs: name a metric, name the axis the bug varies on, drive a real browser over the DevTools Protocol, read the numbers out of the DOM at every step of that axis, and let the table kill theories before anyone commits one. The same loop, re-run after the fix, is the proof. The tooling is small: [browser-harness-js](https://github.com/monotykamary/browser-harness-js), a REPL that holds one DevTools Protocol session open, in front of a headless Chrome; the loop is a dozen lines of JavaScript on top of it. On the case that forced this on us, three plausible CSS commits had changed nothing measurable; one thirteen-row table found the cause in a minute, and a second sweep gave the fix. This post is the loop, the probe, the setup, and what still goes wrong. ![](assets/browser-loop-layout-debug-fig1-loop.svg) _Fig. 1: The loop. Six steps, one metric, one table. Agents skip steps 1, 2 and 4 unless told to run them._ ## 1. Why agents guess at layout An agent given "the title looks inset on smaller screens" does something reasonable: it greps the stylesheet for the title, finds a rule, and builds a story around it. `text-wrap: balance` evens line lengths, so surely that is the inset. It edits, takes a screenshot or checks a status code, and reports done. Every step is defensible. The whole is a guess. ![](assets/browser-loop-layout-debug-fig2-layers.svg) _Fig. 2: Source, computed style, layout, pixels. The agent greps the top layer; layout bugs live two layers down, and the probe reads from there._ The stylesheet is the top of four layers. Below it the cascade resolves (and an `!important` in another file quietly wins). Below that the layout engine produces boxes, line breaks and a column width. Below that, pixels. A layout bug is a fact about the third layer. Reading the first layer harder does not reach it, and a single screenshot of the fourth layer is one sample at one size, in whatever font happened to load. The fix is not a smarter agent. It is a loop that forces the agent to read the third layer, across the whole range the bug lives in, before it forms a theory. ## 2. The loop **Step 1, name the metric.** Turn the complaint into a number the browser can report. "Looks inset" became: the heading's box right edge minus the right edge of its widest rendered line, plus its line count. A metric you cannot compute from the DOM is not a metric yet. **Step 2, name the axis.** What does the bug vary with? Here viewport width. Elsewhere it is font size, content length, locale, theme, zoom, or time since load. Pick the axis and its stops before touching code. Thirteen widths from 390 to 1920 covered phones, tablets, every common laptop and a desktop. **Step 3, drive and probe.** A real Chromium, real fonts, the real app. At each stop: set the viewport, load the page, wait for it to settle, run one JavaScript probe inside the page that returns a row. The probe is the heart of the loop and it is small. **Step 4, table.** One row per stop, same columns, and at least one control column that can rule out a whole class of cause. Ours carried the neighbouring paragraph's right edge, so "it's padding" could be answered by comparing two numbers. **Step 5, falsify, then sweep.** Read the table before forming a theory. Look for the constant. Then sweep the suspect variable in a second loop with the same probe. **Step 6, fix and re-run.** Apply the change and run the step-3 loop again. The second table is the proof of done; the first is its negative control. No screenshot is required, though one at the reader's size does no harm. ## 3. The probe and the setup ![](assets/browser-loop-layout-debug-fig3-setup.svg) _Fig. 3: One persistent CDP session in front of a headless Chrome pointed at the dev server. State survives across calls, so the agent issues small snippets instead of one giant script._ We use [browser-harness-js](https://github.com/monotykamary/browser-harness-js), a REPL that holds one DevTools Protocol session open and evaluates JavaScript snippets against it. Chrome runs headless with `--remote-debugging-port`. Any Chromium works; Playwright or raw CDP over a websocket would do the same job. ```js globalThis.out = []; for (const w of [390, 600, 768, 900, 1024, 1100, 1200, 1280, 1366, 1440, 1548, 1600, 1920]) { await session.Emulation.setDeviceMetricsOverride({ width: w, height: 900, deviceScaleFactor: 1, mobile: w < 768 }); await session.Page.navigate({ url: 'http://localhost:3010/reports/commentary/' }); await new Promise(r => setTimeout(r, 2500)); const r = await session.Runtime.evaluate({ returnByValue: true, expression: `(() => { const h = document.querySelector('.content-layout h1'); const rg = document.createRange(); rg.selectNodeContents(h); const rects = [...rg.getClientRects()]; const hb = h.getBoundingClientRect(), cs = getComputedStyle(h); const p = document.querySelector('.article-content p').getBoundingClientRect(); const textR = Math.max(...rects.map(x => x.right)); return JSON.stringify({ w: innerWidth, col: Math.round(hb.width), h1R: Math.round(hb.right), pR: Math.round(p.right), textR: Math.round(textR), gap: Math.round(hb.right - textR), lines: Math.round(hb.height / parseFloat(cs.lineHeight)), tw: cs.textWrapStyle || cs.textWrap, fs: cs.fontSize }); })()` }); globalThis.out.push(r.result.value); } ``` Then, as a separate one-line call, `globalThis.out.join("\n")`. Three details carry the method. `getBoundingClientRect` on the element gives the box the layout engine produced. A `Range` over the element's contents and `getClientRects` gives one rectangle per rendered line, so the widest line's right edge is the true text edge, not the box edge. And the paragraph's rectangle rides along as the control. Swap the selector and the fields and the same shape measures overflow, overlap, tap-target size, contrast, or hydration timing. The second sweep reuses everything and changes one thing: ```js for (const px of [40, 38, 36, 35, 34, 33, 32, 30]) { // inside the same page: h.style.setProperty('font-size', px + 'px', 'important'), then the same probe } ``` ## 4. The worked case The complaint: the memo title looked inset on the right at some window sizes, fine at others. This is the report as it arrived, the reader's own window and marker: ![](assets/browser-loop-layout-debug-issue.png) _The title wraps to three short lines and stops well short of the column the paragraph below fills. Nothing in the stylesheet says why._ Three commits went in before the loop. | attempt | theory | why it changed nothing | | -------------------------------------------------- | --------------------------- | ---------------------------------------------------------------------------------------------------- | | pad the blockquote rule in `markdown.css` | more padding | a second stylesheet sets `padding` with `!important` and wins | | `text-wrap: balance` → `pretty` under a breakpoint | balance evens line lengths | verified with a headless screenshot that had not loaded the web font; the fallback wraps differently | | move that breakpoint to 1280px | wider screens fit two lines | the reader's 1548px window still showed three; the column had not grown | Then the loop, thirteen widths, one probe: | viewport | column | h1 right | p right | widest line right | gap | lines | font | | -------- | ------ | -------- | ------- | ----------------- | --- | ----- | ------ | | 600 | 568 | 584 | 584 | 583 | 1 | 2 | 32px | | 768 | 663 | 716 | 716 | 550 | 165 | 3 | 38.4px | | 900 | 663 | 782 | 782 | 637 | 145 | 3 | 40px | | 1100 | 663 | 882 | 882 | 737 | 145 | 3 | 40px | | 1280 | 675 | 1005 | 1005 | 848 | 157 | 3 | 40px | | 1440 | 675 | 1085 | 1085 | 928 | 157 | 3 | 40px | | 1548 | 710 | 1127 | 1121 | 1125 | 1 | 2 | 40px | | 1920 | 710 | 1313 | 1307 | 1311 | 1 | 2 | 40px | Three theories died in one read. `h1 right` equals `p right` everywhere, so there is no padding. `text-wrap` reads `pretty` and the gap is unchanged, so the wrap mode was never it. And the column is 663px from 768 all the way to 1440, growing only past 1548. That constant is the bug: a 40px serif title in a 663px column breaks into three lines of about 500px, and the next word on each line is too long to fit. No wrap mode moves that. The sweep over font size at the 663px column: | font-size | lines | gap | | --------- | ----- | --- | | 40px | 3 | 145 | | 38px | 3 | 171 | | 36px | 2 | 12 | | 32px | 2 | 3 | Two lines from 36px down. Since the column, not the viewport, decides it, the fix is a container query: `container-type: inline-size` on the layout wrapper and `font-size: clamp(32px, 5.4cqi, 40px)` on the heading, which is 35.8px on the 663px column and 38.3px on 710px. The step-3 loop, re-run: ![](assets/browser-loop-layout-debug-fig4-gap.svg) _Fig. 4: The metric across the axis, before and after. A 145 to 157px plateau across the fixed-column band; 16px everywhere from 600 up after the fix._ | viewport | column | font | lines | gap | | ------------ | ------ | ------ | ----- | --- | | 390 | 358 | 32px | 4 | 9 | | 600 | 568 | 32px | 2 | 1 | | 768 to 1200 | 663 | 35.8px | 2 | 16 | | 1280 to 1440 | 675 | 36.5px | 2 | 16 | | 1548 to 1920 | 710 | 38.3px | 2 | 17 | Both tables went into the pull request's proof-of-done, the second as the green run and the first as the negative control. Total time for the loop, both sweeps and the fix: under fifteen minutes. The three guesses had taken longer and shipped nothing. ## 5. What still goes wrong The loop has its own traps; these are the ones that bit us inside it. The REPL prints only a single bare expression. A multi-statement snippet runs and returns nothing, which looks like a hang. Push rows onto `globalThis` inside the loop and print them with a second call. Headless screenshots lie about fonts. A render taken before the web font arrives wraps text with the fallback face. Numbers from the DOM after a settle delay do not have this problem; a screenshot does. Treat a screenshot as illustration, never as the verdict. Browsers cache images through a page reload. A regenerated SVG was byte-identical on the server (checked with `md5`) and still showed the old version in the reader's browser. If a visual fix "did not take", compare the served bytes to disk before touching the figure again. The settle delay is a guess. 2.5 seconds was enough for this page; a heavier page needs a real readiness signal (a font-load promise, an element's presence) instead of a sleep. And the loop fixes what you measured. The column-relative font size removes the systematic three-line break for titles of this length; another title with other word lengths will still rag by its own words. The metric was "gap for this title", so that is what got fixed. ## 6. Run it on your bug 1. Write the complaint as a number the DOM can report. If you cannot, you do not know what you are fixing yet. 2. Name the axis and list its stops. Cover the whole range, not the size on your desk. 3. Point a real Chromium at the real page with real fonts, over CDP. Give the page a settle signal. 4. Put a control in the row: a neighbouring element's edge, a computed property, anything that rules out a class of cause. 5. Read the table for the constant before you form a theory. 6. Sweep the suspect with the same probe. 7. Fix, re-run the first loop, and paste both tables into the proof. Give the agent this list verbatim. Left alone, it starts at step 3 with a single stop and no table, and that is the guess loop wearing a browser. The tooling is public: [browser-harness-js](https://github.com/monotykamary/browser-harness-js) holds the session; the snippets above run unchanged against any Chromium started with `--remote-debugging-port`. The worked case shipped in the memo frontend (foundation-apps #100). The figures were drawn with fieldnote, our in-house hand-drawn diagram kit, which is not public yet.

Claude Code 2.1.259 turned our Read() deny rules into a Bash tripwire

## TL;DR Since Claude Code 2.1.257, `permissions.deny` rules of the form `Read(...)` apply to Bash commands. The harness parses the command, guesses which files it will read, and checks them against the deny list. 2.1.259 extended the guess to `cd DIR && cmd` compounds and recursive greps. When the guess can't be resolved, the harness prompts the operator, and it does so in `bypassPermissions` mode too. We ran about 40 such rules, installed by our own guardrails package, so unattended sessions kept stopping on reads of the current directory. A prose rule telling the agent to avoid one command shape bought a few hours. The durable fix stripped every `Read()` deny from settings and moved the same file classes into our PreToolUse hook. Verdict: a deny list that the harness enforces against Bash is the wrong place for secret-file rules once you run bypass mode; put them in a hook you control and accept that the hook has a bypass marker. ## 1. The prompt Here is the second one I got in a fresh session, minutes after I thought the problem was closed: ``` Bash command cd ~/workspace && grep -rli "sentosa" --include="*.md" --include="*.toml" \ properties family-office notes _inbox 2>/dev/null; ls properties/listings grep on '--include=*.md' after a cd would search a directory that cannot be determined here, and a Read() deny rule is configured; only you can approve running it anyway. Do you want to proceed? ``` The session runs with `--dangerously-skip-permissions`. The agent was doing a plain search across a workspace for lease files. Nothing in that command touches a secret. And the harness still stopped, because it could not prove the command wouldn't. ![](assets/claude-code-read-deny-fig1-prompt.svg) _Fig. 1: The harness infers file reads from a Bash command. Two of the three branches end in a prompt, and the third fires on the mere existence of a Read() deny._ The first version of the prompt, earlier the same morning, read differently: ``` rg on '.' would read '/Users/.../ops-toolkit', which the deny rule Read(**/*.key) covers; only you can approve running it anyway. ``` That one came from `rg -n "Status" file.ts | rg -n "status:" | head`. The second `rg` reads stdin. The harness saw a reader verb with no path argument, resolved it to the working directory, noticed the directory could contain a file matching `**/*.key`, and asked. ## 2. What changed, and when Our deny rules didn't change. I checked every settings backup back to early August; `Read(**/*.key)` and its siblings sit in all of them. What changed is the harness. Two changelog entries: > **2.1.257** Fixed Bash `Read()`/`Edit()` deny rules not applying to `< file` redirects and reader commands like `tac` and `egrep`; a deny rule on any argument or redirect target now refuses the command. > **2.1.259** Fixed Bash `Read()` deny rules not covering files given as option values (`--ignore-revs-file=.env`, `-f.env`, `@file`), `git diff`/`git grep` file operands, or `cd DIR && cat FILE` compounds; `grep -r`/`cp -r` over a directory holding a denied file now asks. Both are filed as fixes, and from Anthropic's side they are: a deny rule that a `< .env` redirect could walk around wasn't much of a deny rule. The consequence for a bypass-mode operator is a new class of stop. The harness now has three outcomes for a Bash read, and Fig. 1 shows them. An explicit path gets matched against the rules and runs on a miss. A reader verb with no path resolves to the working directory, and the directory matches any relative glob such as `**/*.key` because it could contain such a file. A reader verb after a `cd` cannot be resolved at all, so the harness prompts whenever any `Read()` deny exists, anchored to `~/.ssh/**` or not. We asked whether a setting scopes or disables this check. There isn't one. The docs on permissions, the settings reference, and the permission-modes page describe deny rules as applying in every mode, and the only adjacent knob (`disableBypassPermissionsMode`) tightens rather than loosens. The rule list is the only lever. ## 3. Why the prose fix failed Our first response, that same morning, was a line in the global `CLAUDE.md`: never `cd && `, use absolute paths. It worked for that shape. Within the hour the agent emitted a piped `rg` with no path, which the rule didn't name. After that fix, it emitted `cd X && grep -r`, which the rule also didn't name. The trigger set is open. Piped readers, `grep --include`, `git grep`, option-value files, recursive copies. Each prose rule closes one shape and the model complies with the shape it was told about. A cause that lives in `settings.json` needs a fix that lives in `settings.json`. ## 4. Where the rules came from We publish [claude-guardrails](https://github.com/dwarvesf/claude-guardrails), a small installer that merges a deny list and a set of hooks into `~/.claude/settings.json`. It's how every Dwarves machine gets the same floor. Its deny list carried 37 `Read()` rules: relative globs (`**/*.key`, `**/*.pem`, `**/.env`, `**/.env.*`, `**/*.p12`, `**/*.pfx`, a few bare `.env.local` forms) and anchored paths (`~/.ssh/**`, `~/.aws/**`, `~/.gnupg/**`, `~/.config/gcloud/**`, `~/.kube/**`, and so on). On my machine the same settings file also wires [secret-guard](https://github.com/tieubao/dotfiles/tree/main/home/dot_claude/hooks/secret-guard), a PreToolUse hook that inspects Bash, Read, Grep and Edit calls for secret-shaped reads: `op read` without a sink, cat-class verbs on credential files, context-grep dumps of a config, redirects that capture a secret to disk. The two guards overlapped on most file classes and disagreed on enforcement: the harness deny cannot be bypassed by the model, the hook honours an operator marker (`# secret-guard: allow: `) that the agent is told never to write on its own. ![](assets/claude-code-read-deny-fig2-rings.svg) _Fig. 2: Two rings guarded the same files. The outer ring, enforced by the harness, is the one that now stalls on unresolvable Bash reads._ ## 5. What we did Four PRs on the dotfiles repo, one working day. **#358, strip the relative globs.** The guardrails installer runs from a chezmoi `run_onchange` script, which already had a post-install patch (it removes a push-to-main block hook we don't want on solo repos). I extended the patch with a `jq` filter that drops every `Read()` deny whose pattern isn't anchored to `~` or `/`. That killed the no-path branch. It also opened two holes I only saw when I stopped to ask "does this weaken anything" and wrote the coverage table out: a `cat server.key` in Bash was now guarded by nothing, since the hook's Bash-side file class never listed `.key`, and `.pem` reads were unguarded everywhere. **#360 and #361, close the holes.** `.key` joined the hook's Bash class. `.pem` joined both the Read-tool and Bash classes, with public-cert bundles (`/ssl/certs/`, `/ca-certificates/`, `cacert.pem`) blanked before the match, the same way the hook already blanks `.env.example` and friends. **#362, strip every Read deny.** The after-cd branch prompted on the 22 anchored rules I'd kept. Out they went, and the hook took over their file classes: the whole `~/.ssh` directory (private keys carry arbitrary names, so `config`, `known_hosts*`, `authorized_keys*`, `allowed_signers` and `*.pub` are excepted rather than the keys enumerated), `~/.gnupg`, `~/.azure`, the AWS SSO and CLI caches, and the gcloud token databases and legacy credentials. The filter that now runs after every guardrails install: ```jq .permissions.deny = ((.permissions.deny // []) | map(select( test("^Read[ (]") | not ))) ``` And the hook arm on the Read-tool side, trimmed to the new entries: ```bash case "$P" in */.ssh/*.pub | */.ssh/config | */.ssh/known_hosts* | */.ssh/authorized_keys* | */.ssh/allowed_signers) ;; */.ssh/* | */.gnupg/* | */.azure/* | */.aws/sso/cache/* | */.aws/cli/cache/* \ | */.config/gcloud/*.db | */.config/gcloud/legacy_credentials/*) block "Read tool target is a known secret-bearing path: $P" "R1" ;; */ssl/certs/*.pem | */ca-certificates/*.pem | */cacert.pem) ;; *.pem) block "Read tool target is a known secret-bearing path: $P" "R1" ;; esac ``` ![](assets/claude-code-read-deny-fig3-counts.svg) _Fig. 3: Read() deny rules in settings.json went from 37 to 0 across the four PRs; the hook's false-positive suite grew from 258 to 277 cases, all passing, to cover the same file classes._ Each PR shipped with its cases in the hook's test suites and a negative control: the new cases fail on the previous hook (2 of 18 on the first one), which is how we know the test measures the change and not the harness. ## 6. Did it work Both shapes that prompted, run in a bypass-mode session after #362: ``` $ printf 'status: {\n' | rg -n "status: \{" | head -2 1:status: { $ cd ~/workspace/tieubao && grep -rli "sentosa" --include="*.md" properties | head -2 properties/listings/... ``` No prompt. The deny list holds 10 rules, all `Bash(...)` and `Edit(...)`. The hook suites: fp 277/0, taint-tools 24/0, b9 22/0. ## 7. What it cost Enforcement moved one ring outward. The harness deny was unconditional; the hook has a documented bypass. If an agent ever writes `# secret-guard: allow:` on its own initiative, the guard is gone for that command. We mitigate with an instruction the model reads every session, a hook that refuses a bare marker and writes every reasoned one to its audit log, and I'd still rather have the harness rule if the harness let me scope it to the Read tool. It doesn't, so this is the trade. The `.pem` rule will false-positive on a private cert bundle stored outside the three excepted paths. `.env.*` catches `.env.example`, which the harness rule also caught, so nothing regressed there, and the hook's Bash side already blanks the template family. The patch runs after each guardrails install. A machine that installs guardrails without our chezmoi script gets the deny list back and the prompts with it. That's the right default for a machine we don't manage. On ours, `chezmoi apply` is the reset. Two things I found on the way and fixed because they were in the path: our dotfiles watcher failed `launchctl bootstrap` on every apply, because `bootout` returns before launchd finishes teardown and the 451-path WatchPaths agent wasn't gone yet when the script re-bootstrapped it (#359 adds a five-second retry). And a guardrails reinstall overwrites the hook's shared `secrets.json` pattern file, dropping a false-positive downgrade we'd made on the 64-hex rule; `chezmoi apply` catches the drift and asks. ## 8. If you run guardrails-style deny lists Check your Claude Code version. At 2.1.257 or later, list your `Read()` denies: ```bash python3 -c 'import json;d=json.load(open("'"$HOME"'/.claude/settings.json"))["permissions"]["deny"];print([x for x in d if x.startswith("Read")])' ``` If the list is non-empty and you run bypass mode for unattended work, you will get the cwd prompt. Decide where the guard belongs. Keep the harness rules if a human sits at every session and you want the unconditional block. Move the file classes into a hook if you run the agent unattended, and write the hook's bypass so it leaves a trace. Everything here is public. The installer patch, the hook and its test suites live in [tieubao/dotfiles](https://github.com/tieubao/dotfiles), PRs #358 through #362. [claude-guardrails](https://github.com/dwarvesf/claude-guardrails) still ships the deny list unchanged; its other users may want the harness ring, so that default is a separate decision.

Making our site AI-agent-ready, 50 to 93

A new kind of visitor shows up at our sites now. It runs no JavaScript, and it gives up in about a second if it can't find what it came for. It's an AI agent fetching a page for a person who asked it a question, and it wants text, a status code, and links it can follow. We spent a day making [memo.d.foundation](https://memo.d.foundation) and [dwarves.foundation](https://dwarves.foundation) legible to that visitor. The docs site went from 50 to 93 on one scanner, the marketing site from 52 to 85. Here's what the scanner looks for, and what a day of fixes did to the page an agent sees. ![](assets/agent-ready-website-fig1-visitor.svg) _Fig. 1: what an agent does on arrival. It reads the raw HTML with no scripts run, and inside a one-second budget it either finds real content or gives up._ That gap is what the fixes target. A page that renders its answer client-side reads as blank to the agent, because the agent never runs the code that fills it in. The work lives in the bytes on the wire, which is the only thing the agent reads. ## What is-agentic measures is-agentic.com, built by Ora, scores how readily an AI agent can discover, fetch, understand, and use a public website. You point it at a domain, it drives an agent through the site, and it grades the result out of 100. You can run it three ways: the web UI, `npx is-agentic `, or a read-only report API at `/api/v1/report`. It eats its own dog food, which is a good sign. It ships an OpenAPI spec, an MCP server, an `llms.txt`, and the same read-only report API it grades other people on. ![](assets/agent-ready-website-shot-memo-score.png) _A scan of memo.d.foundation. The score sits on the left, the three pools on the right, and the command that produced it runs across the top._ The methodology page publishes the shape of the rubric but not the individual checks. We pulled the check names out of stored reports for a few well-known sites, so the list below is observed rather than official. The API only names a check when a site fails or partially passes it, so anything a site already does right stays invisible in its report. We assembled the roster by reading several sites' failures together. ## How the score is built Three pools, 100 points plus a bonus. ![](assets/agent-ready-website-fig2-rubric.svg) _Fig. 2: the rubric. Two scored pools set the denominator, the bonus adds on top, and any check that doesn't apply drops out of the denominator instead of scoring zero._ The essential 80 carries most of the grade and covers the fundamentals an agent needs before anything else. The recommended 20 only switches on when the site advertises a developer surface, so a plain content site never gets marked down for lacking an API. The clever part is the last column. A check that doesn't apply is excluded from the denominator rather than scored zero, so a brochure site is never punished for missing an API it never claimed to have. Partial results earn proportional credit, and where a check appears twice (the MCP surface exposes duplicate IDs) the scores average. For reference, on the day we ran this, Vercel scored 85, Stripe 74, GitHub 61, and Shopify 60. So the bar is real. Even good engineering teams sit in the 60s and 70s until they do this work on purpose. ## Every check, and how to pass it This is the part worth keeping. For each check we'll say what it wants, how the scanner probes for it, what a pass looks like, and why an agent cares. You can read your own site against this list without running the scanner at all. ![](assets/agent-ready-website-shot-memo-checks.png) _The scanner's own breakdown of the Essential pool: each check, its verdict, and the evidence behind it._ ### The essential checks **`content-no-js`** wants real content in the raw HTML: an H1 and at least 500 characters, with no JavaScript run. The scanner fetches the page the way a cheap agent does, takes the bytes off the wire, and reads them without a browser engine. A pass means the H1 and the body text sit in the HTML you'd see from a plain `curl`. An agent on a budget won't boot a headless Chrome for you, so if the words live in `__NEXT_DATA__` and get painted by React, the agent sees an empty `__next` div and leaves. Our dwarves.foundation homepage shipped 17,893 bytes with zero `

` and every word behind `__NEXT_DATA__`, which read as blank. `agent-friendly-404` wants a real 404 status on a path that doesn't exist, plus a body that points the agent somewhere useful. The scanner requests a random unknown path and reads both the status line and the body. A pass is a 404 with a short body naming the sitemap, the `llms.txt`, and the homepage. An agent that gets a 200 and a full homepage for `/nope` believes every URL it guesses is a real page, so it can't tell a typo from a route. Our memo baseline answered every unknown path with a 200 and the home shell, and d.foundation answered a 301. `json-error-responses` wants API errors delivered as JSON, not as an HTML error page. The scanner hits an API path that errors and checks the content type of the body. A pass is `{ "error": string }` with the HTTP status preserved. An agent parses an API answer as JSON, so an HTML 500 page makes the parse throw. Our failure was specific: an unrouted `/api/` path fell through to the framework's default and came back as `text/plain 404`, which is exactly the path the scanner probed. `markdown-negotiation-vary` wants the page served as markdown when the caller asks for it with `Accept: text/markdown`, and a `Vary: Accept` header so a cache keeps the two forms apart. The scanner sends `Accept: text/markdown` and inspects the content type and the Vary header on the way back. A pass is `content-type: text/markdown; charset=utf-8` alongside `vary: accept`. Markdown is cheaper for an agent to read than HTML wrapped in layout, and without the Vary header a CDN can hand the markdown to a browser or the HTML to an agent by mistake. Our memo baseline returned `text/html` with no Vary at all. `openapi-spec` wants a machine-readable API description at a URL an agent can guess. The scanner looks for a spec at a predictable path such as `/openapi.json`. A pass is a valid OpenAPI document served there; we published 3.1 covering the 13 public routes. The spec is how an agent learns your routes, params, and response shapes without scraping prose out of a docs page. `oauth-support` and `scoped-permissions` want honest auth when the site has auth: standard OAuth flows, and scopes that bound what a token can do. The scanner looks for OAuth metadata and scope declarations wherever a login exists. A pass is standard endpoints and named scopes. An agent acting for a person needs a sanctioned way in, and scopes limit the blast radius if a token leaks. On a public read-only API neither check applies, so the rubric drops both from the denominator rather than scoring them zero. That's the excluded column doing its job. ### The recommended checks These only switch on once the scanner sees a developer surface: an API, OAuth, GraphQL, MCP, a dev portal, or commerce. memo counts 17 recommended checks because it exposes an API and an MCP surface, so adding surfaces widens the denominator you're graded against. `sitemap` wants `/sitemap.xml` listing the site's URLs. The scanner requests that path. A pass is an XML sitemap; web-engine now builds one with 55 URLs. It's the index an agent uses to find every page without crawling links blind, and dwarves.foundation answered a 404 here at baseline. `json-ld` and `org-schema-completeness` want a schema.org JSON-LD block, and for the Organization type to carry its real fields such as `contactPoint` and `PostalAddress`. The scanner parses the page for `application/ld+json` and checks the Organization shape. A pass is one Organization block per page with values that resolve. It's how an agent reads who publishes the site and how to reach them in a format it doesn't have to infer. We read every value from `site.json` and left `telephone` out, because no phone number exists anywhere in the content repo, and an empty field is more honest than a placeholder. `metadata-completeness` wants a self-referencing canonical, an `html lang`, an `og:image`, and an `og:type`. The scanner reads the head. A pass has all four. The canonical stops an agent treating query-string variants as separate pages, the lang tag tells it the language, and the OG pair give it a title card to quote. memo carried no canonical on any page at baseline; we added it to 1519 of 1521 exported pages. `trust-anchors` wants `/about`, `/contact`, and `/privacy` pages with real substance, 500-plus characters each. The scanner fetches those paths and measures the body. A pass is substantive pages rather than stubs. An agent deciding whether to trust a source reaches for the same anchors a careful person does. `agent-instruction` wants a "when to use this" section inside `llms.txt`. The scanner reads `llms.txt` for guidance beyond a link list. A pass is a section that states what the site is for and when an agent should reach for it. It lets an agent route to you for the right questions instead of guessing from the domain name. memo's `llms.txt` was a bare link index until we added this. `api-versioning-policy` wants a version in the API URL or a documented deprecation policy. The scanner checks for `/v1/`-style paths or a stated policy. A pass is `/api/v1/` with the old unversioned path kept as a permanent alias, plus a written deprecation policy. An agent that hardcodes your endpoint needs to know the contract won't shift under it without warning. `rate-limit-headers` wants the IETF RateLimit headers so a caller can pace itself, and a 429 with `Retry-After` when it goes over. The scanner reads the response headers and the 429 shape. A pass emits `ratelimit` and `ratelimit-policy` on every response. A considerate agent backs off when you tell it the budget, and without the headers it either hammers you or crawls. We sized the limiter by counting real traffic, which the climb section covers. `api-error-model` wants a typed error schema, referenced the same way across every route. The scanner compares error bodies across endpoints for a consistent shape. A pass is one error type, referenced in the OpenAPI spec. An agent writes a single error handler when your errors share a shape, and a tangle of special cases when they don't. `developer-portal` and `public-api-docs` want a docs surface an agent can find by name, like a `/developers` page, with the API documented behind it. The scanner looks for the portal at the obvious path and for linked docs. A pass is a `/developers` page that names the base URL and the auth model in plain language. It's the front door an agent checks before it goes looking for a spec. `function-calling-compat`, `mcp-server`, and `cli-tool` want surfaces an agent can call directly: an API shaped for function-calling, an MCP server, and a command-line tool. The scanner detects each surface where it's advertised. A pass is the surface existing and answering. The closer your site sits to something an agent can invoke, the less it has to improvise. memo scored partial on all of these; its MCP server exists, and adding Streamable HTTP transport would carry it to a full pass. `agentic-search-specific`, `brand-search-accuracy`, `onboarding-friction`, and `api-schema-analysis` read reputation and shape rather than a single header. `brand-search-accuracy` asks whether your name resolves to you on a clean search, and it failed for d.foundation because "d.foundation" doesn't rank, which is a naming reality no header fixes. The other three grade how discoverable your agent-facing surfaces are and how cleanly your schema reads. We didn't get a precise probe shape for these out of the reports we read, so we're describing what they reward rather than a request you can replay. ### The bonus tier The bonus rewards emerging agent-facing formats and never penalizes their absence, so it can only lift a score. The reports we pulled didn't expose the individual bonus check IDs the way they exposed the essential and recommended ones, so we're leaving the specific names out rather than guessing at them. memo carried 1.9 bonus points at baseline and d.foundation 0.6, which tells you the tier is live even on a site nobody targeted it with. ## Where each site comes from, and why it set the ceiling Before any fix, we had to know where each site comes from, because the answer decided what was possible. ![](assets/agent-ready-website-fig3-buildhost.svg) _Fig. 3: build versus host. GitHub Actions builds each site and hands Cloudflare a finished directory. memo lands on a Worker, dwarves.foundation on a Pages project, and that product choice set each site's ceiling._ Cloudflare never sees a repo. GitHub Actions builds each site and hands Cloudflare a finished `./out`. That one fact carried a trap we walked into. The marketing site's renderer, `web-engine`, had been archived weeks earlier, yet the site kept deploying, because an archived public repo still clones at build time. The break only surfaced when we tried to push a fix and the push bounced off a read-only repo. We unarchived it, landed the work, and wrote down the rule: a repo stays unarchived while it's load-bearing. The two sites also sit on different Cloudflare products, and that difference set the ceiling for each. A Worker runs code on every request. A Pages project serves static files. Half the essential checks, a real 404 body and markdown negotiation among them, need code at request time. So memo, already a Worker, could reach every check, while the marketing site on Pages looked stuck. Then we learned Pages runs a `_worker.js` dropped into the build output, with the same asset binding a Worker has. We'd first assumed the marketing site needed a migration off Pages to run any request-time code, and that was wrong. The correction sits in our decision record now, because the mistake nearly cost the site three checks it could keep. ## From 50 to 93, round by round memo moved in four scored jumps: 50, then 62, then 71, then 91. ![](assets/agent-ready-website-fig4-climb-animated.svg) _Fig. 4: the score climb. memo across four PR rounds against dwarves.foundation across three, with Vercel, Stripe, and GitHub drawn in as reference lines. The chart plots the four scored rounds to 91; later polish took memo to 93, where it sits now._ 50 to 62. The baseline homepage answered every unknown path with a 200 and the full home shell, so an agent believed every URL was a real page. We gave `df-memo`'s worker a real 404 with a short markdown body pointing at the sitemap and `llms.txt`. We added a self-referencing canonical and an Organization JSON-LD block to every page, gave `llms.txt` a "when to use" section, and taught the worker to serve a page's markdown on `Accept: text/markdown` with `Vary: Accept`. The homepage itself learned to negotiate and to render its memo rows into the static HTML instead of fetching them client-side. That markdown negotiation is the single mechanism doing the most work, so it's worth seeing whole. ![](assets/agent-ready-website-fig5-negotiation.svg) _Fig. 5: content negotiation. One URL forks on the Accept header: an agent asking for markdown gets the `/content/.md` twin with `Vary: Accept`, a browser gets the rendered page._ The worker maps a page route to its markdown twin under `/content/`, so `/playbook/design/ux-design` has a sibling at `/content/playbook/design/ux-design.md`, and the Accept header decides which one you get. The check that reads cleanest as evidence: ```shell $ curl -sI -H 'Accept: text/markdown' https://memo.d.foundation/playbook/design/ux-design HTTP/2 200 content-type: text/markdown; charset=utf-8 vary: accept $ curl -sI https://memo.d.foundation/nope-a-real-404 HTTP/2 404 content-type: text/markdown; charset=utf-8 vary: accept ``` 62 to 71. memo has an API behind `/api/`, so the recommended pool switched on and the site started failing the developer-surface checks. We wrote an OpenAPI 3.1 spec at `/openapi.json` for the 13 public routes, published a `/developers` page, and made the API answer JSON on every error. The scanner had been failing `json-error-responses` for a plain reason. An unrouted `/api/*` path fell through to the framework's default and came back as `text/plain 404`, exactly what the scanner probed. The worker now re-clothes any non-JSON API error as `{ "error": string }` with the status preserved. One content-model bug hid inside this round. The vault's markdown wraps a JSX heading's newline children in a paragraph, which broke the H1 the `content-no-js` check counts, so the fix landed in the brainery vault rather than in the renderer that serves the page. 71 to 91. The last jump was API maturity. We added `/api/v1/` URL versioning at the edge with the unversioned path kept as a permanent alias, a real per-client rate limiter that answers 429 with `Retry-After` and emits the IETF RateLimit headers, and a documented deprecation policy. We sized the limiter by counting, not guessing. A cold homepage fires eight API calls, so 600 per minute is about ten times what one active human generates and still stops a scraper. ```shell $ curl -sI https://memo.d.foundation/api/v1/tags HTTP/2 200 ratelimit: "public-api";r=599;t=31 ratelimit-policy: "public-api";q=600;w=60 ``` A last pass of smaller fixes after those four rounds, the vault H1 content-model bug and a few metadata gaps, took memo to 93, which is where the scan above sits. dwarves.foundation ran the same play on its `_worker.js`. We server-rendered the page body to one H1 per page, added the sitemap, `llms.txt`, canonical, and Organization JSON-LD, wrote a markdown 404 body, and gave `robots.txt` a Sitemap line. The root cause of its `content-no-js` failure we found by building and bisecting rather than by reading: `template-render.tsx` gated the whole template behind an `isClient` flag and returned `null` on the server, so the static export emitted an empty `__next` div. Removing the gate took `out/index.html` from 0 to 4 `
` and from 77 to 4,235 visible characters, with byte-identical full-page screenshots before and after and no hydration warning on seven routes. That site climbed 52 to 79 to 85. ![](assets/agent-ready-website-shot-dwarves-score.png) _dwarves.foundation after the same work: 85 out of 100, held back only by the markdown negotiation a static Pages site can't do as cheaply as the Worker._ ## The two fixes we refused Two fixes would have raised the number and we refused both. The marketing site is authored as components, so its "markdown" is JSX under the hood. The homepage prose lives inside `title="..."` attributes instead of paragraphs. We could have served those files on `Accept: text/markdown` and passed the negotiation check. We didn't, because what an agent would receive is worse than the server-rendered HTML it already gets. Passing that check would have made the site score higher and read worse. The rubric exists to serve the agent, and a check that rewards a downgrade has lost the plot for that one case. The scanner also wants a developer portal with "API keys and a sandbox". memo's API is public and read-only. We wrote that plainly on `/developers` rather than invent a key-issuance flow and a sandbox that don't exist. A faked surface is a worse answer to an agent than an honest "this is public, here is the base URL", because the agent will try the fake and get nowhere. One more honesty note worth keeping. The scanner's own evidence carries a timestamp. Twice it reported "no H1" on a homepage we'd already fixed, because the scan ran before the deploy finished. We learned to compare the scan time against the last deploy before trusting a single finding, and to verify each claim with a direct request rather than a rescan. ## Run this on your own site Two ways to run this yourself. The fast one is the scanner we used: ```shell $ npx is-agentic your-site.com ``` It prints a score and the failing checks. Read its evidence with a timestamp in mind, and confirm each finding with a direct request before you act on it. The slower one is the checklist we ended up with. Every line is a request you can run by hand against your own domain. Walk it top to bottom, or grab the one-page version below and print it. Essential - [ ] Homepage has an `
` and 500+ chars of text in the raw HTML (curl, no JS) - [ ] An unknown path returns 404 or 410, never 200 with the app shell - [ ] The 404 body carries a short text pointer to `/sitemap.xml` and `/llms.txt` - [ ] API errors come back as JSON with a code and message, never `text/plain` or HTML - [ ] `Accept: text/markdown` returns markdown, with `Vary: Accept` on it and on the HTML - [ ] `/openapi.json` exists and parses as OpenAPI 3.x Recommended (only if you expose an API or dev surface) - [ ] `/sitemap.xml` lists every indexable URL - [ ] Every page has a self-referencing `` - [ ] Every page carries Organization JSON-LD (name, url, logo, sameAs, contactPoint, address) - [ ] ``, `og:image`, `og:type` present - [ ] `/llms.txt` has a "when to use" section, not just a link index - [ ] The API base carries a version (`/v1/`) or a documented deprecation policy - [ ] API responses emit the IETF RateLimit headers, and 429 adds `Retry-After` - [ ] 4xx and 5xx responses reference one consistent typed error schema - [ ] A `/developers` page states the auth reality plainly (no faked sandbox) Grab the [one-page cheat sheet](assets/agent-ready-website-cheatsheet.html) if you want a printable version to tick off by hand. ## The tool we kept We keep the machine version of that list as an internal audit tool, so a site never drifts back down without us noticing. It runs the same three tiers against any domain on demand and files each failing check as a work item in the repo that owns the site. Inside our dev kit it lives as a skill called `web-drift`: name the sites once, run it whenever, and read back a list of findings with the evidence attached. ![](assets/agent-ready-website-fig6-webdrift.svg) _Fig. 6: the audit loop we kept. web-drift reads the sites a repo declares, probes each with the same three tiers, and files every failing check back into that repo's backlog with the evidence._ Building it paid off in a way we didn't plan for. The fresh reimplementation reproduced a security hole in the original tool that a chain of quick patches had walked right past, which is a good reason to rebuild a tool you mean to rely on. Whether we open it up for anyone to run is a decision worth making on its own, because the checklist above is most of the value and it costs nothing to share. The agent that fetched this page ran none of that guesswork. It asked for markdown and got markdown, and it found the sitemap where the `llms.txt` said it would be.

The deploy pipeline formula

The site you're reading publishes itself on every push. A merged post kicks off CI, which compiles about 2,000 markdown files, builds 3,080 static pages, and deploys three Cloudflare surfaces: a static Worker, an API Worker, and a D1 search index. That step showed 1m50s under a green checkmark. We spent a morning reading its raw log line by line. The step now runs in 78 seconds, and the time was the least valuable thing we found. ## Read the log as a timeline A CI step hides a dozen phases behind one duration number. The raw log has a timestamp on every line, so the first move is to index it: mark where each phase starts, subtract, and write down the table. | Phase | Time | | ----- | ---- | | Vault fetch + install | 9s | | Markdown compile (1,954 files) | 9s | | Metadata generators | 4s | | Next.js build (3,080 pages, warm cache) | 27s | | RSS, redirects, lint bundle | 9s | | Deploy static Worker | 17s | | Deploy API Worker | 8s | | R2 upload | 4s | | D1 seed | 11s | Two things jump out of a table like this that never jump out of a checkmark. The build core was already tight: 27 seconds for 3,080 pages with a warm compiler cache is fine, and we didn't touch it. The tail was the problem: 40 seconds of deploys and uploads running one after another, none of which depended on each other. Figure 1 shows the same numbers to scale, before and after. ![](assets/deploy-pipeline-fig1-timeline.svg) _Fig. 1: the publish step to scale. The build core stayed untouched; the entire win came from the tail's shape._ ## The green checkmark was hiding three bugs Reading that closely also surfaced errors that had been shipping for weeks, because a step that exits 0 gets no scrutiny. The generator DAG ran one step a stage too early (fig. 2). `generate-directory-tree` reads two JSON files that another generator writes, and it ran in the stage before the one that writes them. It logged an ENOENT stack trace, caught it, and printed "Done (0.8s)". Every publish shipped a directory tree built from files that didn't exist yet. The fix is one line in the stage list, plus the habit the bug taught us: write the dependency reason as a comment next to the stage, so the next person who reorders it has to argue with the comment. ![](assets/deploy-pipeline-fig2-dag.svg) _Fig. 2: the generator DAG. The dashed box is where directory-tree used to run; its two inputs are written by the stage it now follows._ The API Worker deployed before its database migrations ran. Nothing had blown up yet because no recent migration was load-bearing at deploy time. The day one is, the new code hits production a few seconds before the table it needs. Expand/contract is the boring, correct order: migrate first, deploy second. The cleanup job was failing silently on most runs. Our PR-preview reaper runs under `set -euo pipefail`, and its target list came from a `grep` in a pipeline. On any PR with no worker changes, `grep` matches nothing, exits 1, and pipefail kills the step before it can print "nothing to reap". Six red runs in a row, all from the guard clause. `{ grep ... || true; }` is the whole fix. ## The formula Here's the order we now hold every pipeline to, general first: 1. Path-filter the trigger. A run that starts is the most expensive no-op. 2. Guard before work: check env vars, read secrets capture-first, fail in seconds instead of after the build. 3. Diff the push range per deployable. Our most common push is a memo post; it now skips the API deploy entirely, because the diff proves the API didn't change. Every uncertain answer falls back to deploying, so the skip can only ever be a correct no-op. 4. Run generators as a staged DAG, parallel inside each stage, with the dependency reason written next to the stage. 5. Keep caches on the runner. A persistent local dir for the compiler cache beats a 400MB cloud-cache tarball round trip by about 40 seconds. 6. Run the deploy tail in parallel. Independent jobs cost max() instead of sum(). Ours went from 40 seconds to 18 (fig. 3). 7. Migrations before code, always. 8. Write deltas. Our D1 seeder hash-gates rows ("0 changed of 1,611"), and Wrangler's asset manifest uploads only changed files: one file of 10,921 on a typical post. 9. Retry idempotent network calls three times. Never retry a step whose repeat changes state. 10. Sweep hazards by property. Oversized files get dropped by a size test; a filename list rots on the next addition. ![](assets/deploy-pipeline-fig3-tail.svg) _Fig. 3: the deploy tail restructured. Same four jobs; the only ordering that matters survives inside the data-plane lane, and a diff-clean push skips the api deploy outright._ The memo-specific parts stay memo-specific: the vault submodule advance, the redirect-map dance around Cloudflare's 2,000-rule cap, the search-index seeds. A formula that claims those would be lying about its portability. ## Where it landed The first run on the new pipeline, phase by phase, straight from the log (fig. 4): ![](assets/deploy-pipeline-fig4-landed.svg) _Fig. 4: the landed shape. The step reads 79 seconds; the job wall clock reads ~113, because 34 seconds of Actions overhead (runner prep, toolchain setup, a 1Password CLI download) sits outside the step we measured._ ## The habit underneath The pipeline was "working" the whole time. Pages published, checks were green, nobody was paged. The 110-second version and the 78-second version look identical from the outside, and the outside is where CI dashboards live. The log with timestamps is the only honest surface a pipeline has. Read it top to bottom once a quarter, or the first time a step's duration makes you frown. Budget an hour. Ours paid for itself before lunch.

DeepSeek Harness, dissected

## TL;DR DeepSeek released an open-source agent harness, `dsh`, and we read the codebase within a day of the drop. Under the "everything is a plugin" tagline sits a real architecture: a Cordis plugin tree composed from ordered patch layers, a small control spine surrounded by swappable capability seams, and one load-bearing invariant that says anything the model sees must derive from an append-only session log. It reads Claude Code instruction files natively, bridges Claude Code hooks, and can even drive Claude Code as a subagent. It is also a developer preview that promises breaking changes. Our verdict: study the design now, run it as a cheap DeepSeek-backed worker if you want, and hold off on betting real automation on it until the plugin API settles. ## 1. Background An agent harness is the runtime around a model: the loop that assembles prompts, streams responses, executes tool calls, and keeps session state. Claude Code and Codex CLI live in this slot. `dsh` ([deepseek-ai/deepseek-harness](https://github.com/deepseek-ai/deepseek-harness)) is DeepSeek's entry, and it crossed 33k GitHub stars within hours of release. The pitch is architectural. Every part of the product is a plugin on the [Cordis](https://github.com/cordiverse/cordis) framework, including the model adapter, the tool registry, and the agent loop itself. There is no privileged core to patch. You extend it by mounting a plugin beside the others, and every registration is a reversible effect that unwinds when its plugin unloads. Figure 1 shows where it sits. A harness is one layer of a working stack; the process machinery a team runs on top (specs, gates, review machinery, instruction files) and the models underneath both stay put when the harness changes. ![](assets/deepseek-harness-fig1-slot.svg) _Fig. 1: dsh occupies the harness slot. It competes with Claude Code and Codex CLI, and it leaves the layers above and below untouched._ ## 2. Architecture ### 2.1 Boot: profiles as patch stacks A running dsh is composed at boot from ordered layers over an empty root (fig. 2). A profile names a stack of bundles, each bundle contributes config rows plus the code they mount, and then the user's patch files apply on top. A patch targets a row by id and either replaces it whole or inserts new rows. `web` and `headless` ship as template profiles. ![](assets/deepseek-harness-fig2-boot.svg) _Fig. 2: boot composition. The config model is a layered patch stack over a plugin tree, and `--dump-config` prints exactly what your machine boots._ This replaces the flat settings file most harnesses use. The inspectability matters more than the layering: any row the dump prints, a user patch can replace, which turns "can I change this behavior" from a feature request into a config edit. ### 2.2 The spine and the seams Six core services form the control spine: the session log, the agent registry, the loop driver, the tool registry, prompt assembly, and the model adapter registry. Everything else is a capability seam: a declared interface with swappable providers (fig. 3). ![](assets/deepseek-harness-fig3-seams.svg) _Fig. 3: the control spine and the seams around it. A seam is three roles: a service definition, a provider, and a consumer._ The seam design carries the most interesting consequences. Filesystem and subprocess providers share one execution world, so pointing both at an [E2B](https://e2b.dev) sandbox moves Bash, PTY, and LSP to remote execution with zero forked tools. The subagent seam goes further: a "subagent" can be an in-process child, an ACP peer, a Codex process, or a Claude Code process, all behind one interface. dsh is built to orchestrate other harnesses, which positions it as a meta-harness over the rest of the field. ### 2.3 The turn loop and its one invariant A step is one model request plus the tools it calls; a turn is zero or more steps (fig. 4). Live control flows through typed events, and the interesting ones are waterfalls: around-middleware where a listener wraps the call, then either delegates via `next()` or short-circuits to own the decision. ![](assets/deepseek-harness-fig4-turn.svg) _Fig. 4: turn flow. Durable facts land in the session log; live interception happens on the `agent/*` waterfalls._ The invariant at the bottom of fig. 4 is the soundest piece of the design. Model-visible means logged: anything that reaches a model request must be reconstructable from the append-only session log, and a runtime assertion enforces it. Fork, resume, replay, transcripts, and token metering all derive from that one stream. Context compaction is just another plugin listening for pressure on the pre-step waterfall. The transcript here is the source of truth, and the rest of the system is a projection of it. ### 2.4 The tool pipeline Tool calls run through a guarded pipeline (fig. 5): pre-execute hooks and permission checks, monotonic guards, a one-shot approval prompt, an execute wrapper for timeouts and retries, then post-execute rewriting before the result freezes into the log. ![](assets/deepseek-harness-fig5-pipeline.svg) _Fig. 5: the tool execution pipeline. Policy, sandboxing, and rewriting all attach to waterfall events without touching the loop._ These are the same interception points a Claude Code hook config targets. The trade is expressiveness against simplicity: typed in-process waterfalls are strictly more capable than shell subprocesses speaking exit codes over stdin, and they cost you the write-a-bash-script-in-five-minutes accessibility that made Claude Code hooks spread. ## 3. What carries over from a Claude Code setup We checked the interop surface against a working Claude Code shop: | Existing asset | dsh support | Mechanism | | --- | --- | --- | | `AGENTS.md` / `CLAUDE.md` | Native | Walks root to cwd, dedupes identical siblings, injects as durable context, tracks later file changes | | Claude Code hooks | Partial bridge | `hooks-claude-code` runs the shell command-hook subset on dsh interception points, with CC-shaped payloads and env substitution | | Skills | Concept ports | `ctx.skills` with filesystem discovery and a model-facing loader | | MCP servers | Yes | Built-in MCP client | | Claude Code itself | As a subagent | `subagent-claude-code` delegates a turn to a Claude Code process | | Models | DeepSeek first-class, plus catalog and custom OpenAI-compatible providers | Keys live in `$DSH_HOME/.credentials.yaml`; env-var references supported | The compatibility posture is deliberate. A team keeps its instruction files and hook scripts on day one, and native plugins remain the upgrade path once something outgrows the bridge. ## 4. The dev-kit check We run a spec-driven dev kit, [dwarves-kit](https://github.com/dwarvesf/dwarves-kit), on top of Claude Code. It owns the operating layer in fig. 1: specs, a proof-of-done gate that blocks a push until the change shows a real green run, review lenses, and board state for the work itself. A new harness in the slot below raises one concrete question for us: how much of the kit moves. We audited it piece by piece: | Kit piece | On dsh today | How | | --- | --- | --- | | `AGENTS.md` operate-contract | Moves as-is | Native instruction loading, same precedence walk | | Skills | Moves conceptually | `ctx.skills` filesystem discovery covers the same shape | | Command-hook gates | Moves with limits | The CC bridge runs shell command hooks; config binds per process, so per-repo gating needs care | | Ship-gate ledger, worktree isolation | Stays behind | Assumes Claude Code plumbing; a real port means a native Cordis plugin | The instructive part is why the portable pieces are portable. Everything that lives in files a harness merely reads (contracts, skills, specs) moves for free. Everything wired into one harness's runtime (session hooks, worktree mechanics) pays a port cost. That ratio is a design grade for a dev kit, and it argues for keeping the process layer file-shaped wherever possible. We are leaving the port alone while dsh carries its preview label. The audit already paid for itself: it told us which parts of our own kit are harness-coupled, and that list is now a refactoring target independent of whether dsh wins. ## 5. Design notes Three observations from the read, beyond the diagrams. **The plugin bet is real.** The loop driver itself is a replaceable service. Claude Code exposes fixed extension points; dsh exposes the whole tree. The cost is a steep mental model: Cordis contexts, service injection, reversible effects, and four event dispatch modes stand between you and your first non-trivial plugin. **Log-first state deserves copying.** "Model-visible means logged" is a design rule any agent runtime can adopt, whatever the framework. It buys deterministic replay and honest token accounting, and it forces every new model-visible feature to declare a durable event type instead of smuggling context in from the side. **Web-first is a launch choice worth noticing.** The shipped profiles are `web` and `headless`. The docs mention a TUI profile only as a hypothetical install. Terminal-native developers, the crowd Claude Code won first, are visibly second in line here. ## 6. Limitations The project labels itself a developer preview and promises compatibility-breaking changes, so plugin investments made today may not survive the quarter. DeepSeek's own chat route is text-only; image input needs another provider. And the ecosystem is hours old: lookalike packages appeared on other registries almost immediately, so the official surface is the npm package `@deepseek-ai/dsh` and the `deepseek-ai` GitHub org, nothing else. ## 7. Verdict For a team already running Claude Code: keep your cockpit, read their session-log design, and try dsh where a cheap DeepSeek-backed headless worker fits (`dsh --profile headless "job"`). The architecture is ahead of the product right now. When the preview label comes off, the interop bridges mean switching costs will be lower than they usually are in this space, and that alone makes it worth tracking. ## References - [deepseek-ai/deepseek-harness](https://github.com/deepseek-ai/deepseek-harness), the repository and its `docs/architecture.md`, `docs/cordis-primer.md`, `docs/agent-lifecycle.md`, `docs/tool-execution-pipeline.md` - [Cordis](https://github.com/cordiverse/cordis), the plugin framework underneath dsh - [Agent Client Protocol](https://agentclientprotocol.com), the editor-integration protocol dsh speaks - [E2B](https://e2b.dev), the remote sandbox behind the `fs-e2b` and `subprocess-e2b` providers

Market report August 2026

# Market report August 2026 This edition covers the Elixir ecosystem, current to 2026-08-15. In 2026 the language became gradually typed, and the BEAM became a default home for production AI agents. Both shifts took years, and both landed within months of each other. The report covers the release record, the platform stack, the adoption signal, the durability and data layer, the embedded and local-first flanks, and the security posture. The evidence is the release record, the Hex registry, and the adoption data, not a market projection. The numbers and dates come from the maintainers and the public registries, and they can be checked. ## Key takeaways - **Gradual typing shipped**: Elixir 1.20 infers a set-theoretic type for every program, with a low false positive rate, and many teams drop Dialyzer. - **The web core is mature**: LiveView 1.2 brought colocated CSS, and the patches that followed were security and navigation work. - **The BEAM became an agent runtime**: OpenAI open-sourced Symphony, about 96 percent Elixir and OTP, validating the runtime for agent orchestration. - **The durability layer gained a contender**: Belay runs memoized, durable jobs beside the default, Oban. - **The flanks widened**: Hologram runs Elixir in the browser, and Nerves keeps shipping embedded Elixir. ## The stack at a glance | Component | Current | Released | Note | |---|---|---|---| | Elixir | 1.20.3 | 2026-08-04 | Gradual typing since 1.20.0 (2026-06-03) | | Erlang/OTP | 28.x | 2025 | Base requirement; regex moved from struct defaults | | Phoenix | 1.8.x | 2025-08 | Adopts LiveView 1.2 | | LiveView | 1.2.9 | 2026-06 | Colocated CSS, the 1.2 headline | | Ecto | current | ongoing | The data underlay Ash builds on | | Ash | 3.31.3 | 2026-08-12 | Two security patches this month | | Oban | 2.23.1 | 2026-08-03 | Default for background jobs | | Nx / Axon | 0.8.x | 2026 | Bumblebee models on Nx | | Livebook | current | ongoing | Distributed Python cells | | Hologram | 0.11 | 2026-08 | Pure-Elixir apps in the browser | The dates are release dates from the maintainers. Patch levels move fast. Treat the table as a point-in-time slice. ## Language core The type work shipped in June with v1.20. The compiler infers a set-theoretic type for every program, with no annotations required. It reports two kinds of signal. Verified bugs are typing violations that fail at runtime. Dead code is code the checker can prove unused. The team reports a low false positive rate, and many users drop Dialyzer. The chain is visible across releases. v1.19 checked protocols and anonymous functions in October 2025 and cut compile time by up to four times on large codebases, using lazy module loading and parallel OS-process compilation of dependencies. v1.20 drew the whole language into inference. v1.21, targeted for November 2026, adds recursive and parametric types, then user-facing type signatures. The risk is the one every gradual type system faces in production. False positives must stay low at scale, or teams stop trusting the checker. The signatures do not exist yet. That is the open item to watch. ## Web platform Phoenix and LiveView remain the center of gravity. LiveView 1.2 shipped in June with colocated CSS, styles that live next to the component that uses them and are extracted at compile time for the bundler. It rounds out the colocation story that 1.1 started with hooks and JavaScript. The 1.2 patches that followed were mostly security and navigation work, including redirect scheme fixes and navigation cancellation. The pace is mature, not frantic. ## Durability and data layer Ash keeps a sprint cadence. Three point releases landed this month, two of them security patches on keyset handling. It positions itself as declarative and agent friendly, with generated manifests to call across BEAM nodes. Background jobs gained a contender. Belay runs durable jobs as memoized step sequences, so a crash mid-flight resumes without re-running finished work or paid API calls. It is at 1.0-rc. Oban remains the default and stays close, with AshOban bridging resource actions to Oban. ## The BEAM as an agent runtime Here is the thing that changed the argument for Elixir this year. OpenAI open-sourced Symphony, a reference implementation for orchestrating autonomous coding agents. It polls issue trackers, spawns isolated agent runs, and runs multi-turn work to pull requests. Its reference implementation is about 96 percent Elixir and OTP. The choice was not ceremonial. The BEAM supervises concurrent long-running processes, isolates failures, and hot-reloads code. Those are exactly the primitives agent orchestrators need. The rest of the ecosystem moved to meet the moment. Livebook runs full Python cells with zero-copy Arrow transfers and distributes Python over Erlang distribution. The numerical stack, Nx, Axon, Bumblebee, and Explorer, keeps maturing. Voyager, a new Observer replacement, exposes live BEAM nodes to assistants over MCP. WeaveScope traces agent runs natively on the BEAM. The connector appears everywhere. ## Adoption signal The adoption data draws a clear picture. Figure 1 shows the fifteen largest Elixir-language repositories by stars, from the GitHub topic index on 2026-08-15. ![Horizontal bar chart of GitHub stars for leading Elixir-language repositories, August 2026](assets/fig1-ecosystem-stars.png) **Fig. 1.** Leading Elixir-language repositories by GitHub stars, August 2026. The web, realtime, and analytics core dominates the head; the breadth below is the long tail. Data from GitHub topic search, 2026-08-15. The head is not the whole story. The mid-tail carries the platform bets. Livebook carries the notebooks, Nx the numerics, Nerves the embedded work, and Ash the data layer. Tooling like Credo sits beside the frameworks that built the ecosystem. ## Embedded and local-first Elixir did not stop at the web. Nerves keeps shipping embedded Elixir. AtomVM keeps the tiny VM alive. The VM hobbyists are active. PON-BEAM re-architects the runtime on a notification-oriented paradigm, and LING runs Erlang with no operating system at all. Neither is product-ready, and both are a live proof of how much room the runtime still has. Local-first has a real champion. Hologram runs pure Elixir in the browser, and its latest release runs Elixir regexes on the client with server-matching semantics. It is at 0.11 and carrying its first production apps. Aura, announced in August, is an experimental Elixir variant that compiles to native binaries, a separate direction with no BEAM and no release. ## Security and supply chain The supply chain hardened twice over. HexDocs moved to per-package subdomains after a security audit. Elixir has shipped attested software bills of materials since 1.19, in CycloneDX and SPDX formats. The community warns about a new failure mode. AI-generated SEO posts label critical Elixir remote code execution as safe. On any vulnerability claim, read the primary source. The patch cadence across Phoenix, LiveView, and Ash through August shows the maintainers are responsive. ## Outlook 1. Typing adoption in production. Watch false positives and the v1.21 signatures. 2. Agent orchestration on the BEAM. OpenAI's choice plus distributed Python plus MCP integration. 3. Local-first with Hologram and native-compile Elixir with Aura. 4. Supply chain hardening through 2027. 5. The jobs and durability race, Belay against Oban Pro. Three claims in the report need a check. First, verified bugs with low false positives is a promise; the production record is young, and the signatures do not exist. Second, the agent story is orchestration and operations, not Elixir becoming a better model layer. Third, the security noise means trust is earned per advisory, not inherited. The shape is coherent. The language got a type system. The runtime became an operational model for agents. The base, web, realtime, and fault tolerance, never stopped shipping. That is a rare position for a language to hold at once. Related: [On agentic AI](), and the [arc series]().

What stays valuable when anyone can build anything

# What stays valuable when anyone can build anything When building gets cheap, value moves to the two inputs that cannot be made: judgment inside the firm and trust outside it. This post shows the mechanism from first principles. It uses figures and it names where the argument leaks. It is a framework, not a prediction. Dwarves uses this lens to run its build-by-fleet operations. ## What actually stays valuable when building gets cheap? When production stops being the bottleneck, the scarce goods become the ability to choose and the ability to be chosen. Inside the company, that is judgment. Judgment knows which actions move a goal forward. Outside the company, it is trust and attention. Trust and attention make people believe in you and follow you. Everything else, the execution, becomes a commodity. The market prices it toward zero. All value comes from scarcity. The most fundamental scarcity is biological. You have one body, one mind, and a limited stock of time. Every hour spent on one thing is an hour not spent on another. To beat this limit, you need leverage. Historically, leverage meant the labor of other people. You buy that labor with capital or with equity. Working with other minds has three costs. Context does not transfer cleanly. Objectives do not align. Vision does not survive the passage between minds. Committees average the visions. The output drifts from the intention. AI removes these three costs. AI is synthetic cognitive labor. It gives the same leverage as hiring a team, without the lossy handoff, the politics, or the diluted vision. A firm with one person and a fleet of agents becomes the most efficient unit. This is not because the person is special. The firm has exactly one scarce input left, the owner's capacity to choose. Figure 1 and Figure 2 show the shape. The cost of cognition falls. The value of its complement rises. ![Cheap cognition appreciates its complement: the dashed rising line is the value of judgment and trust, the solid falling line is the cost of cognition](assets/fig1-complementary-goods.png) **Fig. 1.** Cheap cognition appreciates its complement. Cost of cognition (solid) falls toward zero while the value of judgment and trust (dashed) rises to a new equilibrium. Schematic, normalised. ![Relative value shifts as production cheapens: production cost falls while skills, judgment and trust appreciate](assets/fig2-where-value-moves.png) **Fig. 2.** Where value moves when building is cheap. Production cost falls while skills, judgment (inside) and trust (outside) appreciate. Illustrative, not to real scale. ## Where does the value actually sit? Value sits inside where the firm chooses. Value sits outside where the market trusts. Judgment (inside) and trust (outside) are the two scarcities that survive. The cheap thing, cognition, has two complements. The complements match the two acts of business: value creation and distribution. Every act of creation requires an act of selection. Making the thing is cheap. The expensive step is choosing the right thing to make. That is judgment. Judgment is inseparable from competence. Skills do not depreciate. With cheap cognition, you apply leverage to the judgment you hold. You do far more. On the distribution side, cheap content and cheap marketing flood the market. The things consumed with that content, attention and trust, appreciate. Attention is fixed at the biological limit. Trust cannot be bought into existence at scale. People earn trust by being repeatedly right. ## What happened the last four times a factor got cheap? The mechanism is not new. It is the economics of complementary goods. Complements are goods consumed together. When one gets cheaper, the other becomes more valuable. The record is consistent. | Cheap input | Becomes more valuable | |---|---| | Cheap computers | Data (you compute with it) | | Cheap code | Verification (you check it) | | Cheap distribution of media | Attention (you are noticed) | | Cheap cognition (AI) | Judgment (you select), trust (you are trusted) | Each row is the same move. A factor of production deflates. The stuff consumed with it gains value. Cheap cognition is the latest row in a table that has filled for fifty years. The inference follows from the same logic. Judgment and trust are the next columns. We do not predict them from a model that knows nothing. ## How we run on this at Dwarves, with receipts This is not an abstract piece for us. A custom-software firm sells two things. They are the two rising complements. The firm decides what is right to build for a client. The firm is trusted to deliver it. We treat the one-person-company thesis as a load-bearing assumption. We test it on the harness we run. We worked the argument into our internal economics learning track. The complementary-goods row is the transferable concept. Every figure in this post comes from a reproducible script (the `arxiv-style-figure` skill). The numbers and shapes can be regenerated. This is the standard we hold any claim we publish to. ## Where the argument leaks The argument overreaches in three places. First, trust cannot be manufactured is an assertion, not a proof. Brands and platforms produce trust signals constantly. What cannot be faked is repeated, verified trust. Second, the ceiling on what one person can build is the same sits against the same essay. The essay claims one person can now run a large company. The ceiling probably moved too, just less than the floor. Third, attention is fixed per person. Platforms concentrate it. Concentration changes who captures the attention complement. None of these break the direction. They bound it. ## How to reproduce the thinking Apply the complementary-goods lens to the factor that deflates in your market. Name the cheap input. Ask what is consumed with it and cannot be manufactured. That residue is where value moves. Inside a firm, the residue is judgment. Keep it by staying competent and choosing well. Outside the firm, the residue is trust. Keep it by being repeatedly right in public. The method is simple. Watch the cost curve of the factor. Name its two complements. Invest your scarce time in the complement that cannot be automated. Our working answer to the title question is short: judgment inside, trust outside. The rest is the craft of getting good at both.

The tells

A friend sent me a writing checklist last week. One line of instruction came with it: use this when you make the post, so it doesn't sound so load bearing. Load bearing. I knew what he meant before I opened the file. AI prose has a stressed, over-engineered quality, like every sentence was asked to hold up the paragraph above it. You feel the strain before you can name the pattern. We had been through one round of this already. A few weeks back I adopted a writing discipline based on Simplified Technical English, the controlled language that aviation maintenance manuals use: sentences under twenty words, active voice, no nominalization, a banned-word list (leverage, robust, seamless, delve). It helped. The sentences got cleaner. The posts still read like a model wrote them, and for a while I couldn't say why. The checklist answered it. Word-level rules catch word-level defects, and the thing that gives AI writing away now lives a level up, in structure. ## The shapes Some examples, so this stays concrete. - **Corrective negation.** "The problem isn't the AI. The problem is thinking better tools lead to better outcomes." The not-this-but-that pivot, deployed as a reveal. - **The rule of three.** "Readable, maintainable, and solves real problems." Three parallel items, the third stretched a little for rhythm. - **Setup and payoff.** A short question, then the answer delivered as a punchline. "But three weeks later? They hit a tricky bug and were completely stuck." - **The landing sentence.** A paragraph that ends on a tidy epigram, built to be quoted. "The difference is huge." - **Uniform rhythm.** Every sentence between twelve and eighteen words, forever. Every example above comes from a post published on this site under my name. I went back and reread my own writing after the checklist arrived, and it was uncomfortable. The drafts I had run through AI tooling carried these shapes in nearly every paragraph. None of these shapes is wrong on its own. Good essayists use all of them, and they saturate the writing models were trained on because they work: a well-placed triad satisfies, a landing sentence gives a paragraph a click of closure. The tell is density. A human writer spends these effects maybe once a page. A model reaches for one every few sentences, because each one scored well in training and nothing ever taught it to budget them. The result reads like a speech that never stops building toward an applause line. I counted, because the claim felt checkable. Across the older post's 130 prose sentences I tallied 37 of these devices, about 28 per 100 sentences. This post carries one. I also measured sentence lengths, expecting uniform rhythm to be the giveaway, and that one washed out: both posts vary about the same. ![Bar chart of rhetorical devices per 100 sentences across five device families, high in the AI-assisted post and near zero in this one, next to two nearly identical sentence-length distributions.](assets/ai-writing-tells.svg) _Five device families, hand-counted across the two posts, each with a specimen quoted from the older post; beside them, the sentence-length distributions that failed to separate the texts. Prose sentences only; quoted specimens excluded from the counts._ ## What we changed The fix was unglamorous. I turned the checklist into a banned-pattern list and put it beside the word-level rules in the instructions my coding agent loads on every session. It went into the always-on layer deliberately: a style rule sitting in a file the agent may or may not open holds for exactly one session. One existing rule needed surgery. The STE discipline capped sentences at twenty words, and the cap had quietly become a meter. Everything came out the same length, which is its own tell. The cap stays, as a ceiling. Under it, sentence length is supposed to wander. Short. Then something longer that takes its time getting where it's going, because that variation is what a human hand sounds like on the page. There is a caveat taped to all of this. The ruleset fixes form. Whether the post has anything to say is a separate problem, and no checklist catches an empty idea dressed in varied sentence lengths. This post went through the list before publishing. The draft tripped twice, once on a corrective negation and once on a landing sentence, both in the section you just read. I rewrote them, and the paragraph lost nothing.

Releases when agents deploy all day

Our platform monorepo deploys about twenty Cloudflare Workers out of one repository, in one pipeline run, from a manually dispatched GitHub Actions workflow. We added a GitHub Release per production deploy so there would be a durable record of what shipped. Within about half a day the Releases tab had four entries covering roughly two distinct revisions, and we deleted them by hand. Nothing was broken. The pipeline did exactly what we asked. The problem was that we had asked for the wrong thing. ## The three layers ``` Layer Fires Answers --------------- --------------------------- ----------------------------- Deploy every production dispatch did the code ship Release once per merged PR what shipped, and when Live registry on demand what is running right now Drift warning only when inconsistent something is off, look now ``` ![](assets/release-deploy-separation-topology.webp) _The finished pipeline: every dispatch deploys and stamps the commit onto each worker, but only a commit that clears both gates (merged PR, not already released) produces a Release and an alert. The bottom lane reads version state back off the live platform, independent of releases, and pushes a drift warning into the alert only when the fleet is split across commits._ Everything below is the story of arriving at that topology. It looks obvious written down. It was not obvious while we were treating "we deployed" and "we released" as the same event. ## Why the cadence broke the model Release-per-deploy is a fine default when a human decides to ship, writes a changelog, and presses a button on Friday afternoon. It stops being fine when an AI pair-programming session is doing the work. In that mode the loop is tight: make a change, commit, dispatch, look at production, adjust. The deploy button gets pressed because pressing it is how you see whether the thing works, not because a body of work is finished. Some of those dispatches are a one-line copy fix. Some are a retry because the first run looked ambiguous and re-running was cheaper than reading the log carefully. Every one of those minted a release. The tab that was supposed to be a history of meaningful revisions became a log of button presses, and a log of button presses is something we already had, called the Actions tab. The naive fix is a retention policy: keep the last N releases, delete the rest. We did not do that, because it contradicts the reason releases exist. Deleting old releases discards exactly the history worth keeping. The pollution was not a storage problem, it was a trigger problem. ## Gate the release, not the deploy The fix that survived: keep deploying on every dispatch, and gate only the release. Two conditions, either of which skips the whole block (no release, no notification, one log line). **One, the commit came from a merged pull request.** GitHub will tell you directly: ```bash merged_pr=$(curl -sSf -H "Authorization: Bearer ${GH_TOKEN}" \ -H "Accept: application/vnd.github+json" \ "https://api.github.com/repos/${REPO}/commits/${GITHUB_SHA}/pulls" \ | jq -r '[.[] | select(.merged_at != null)][0].html_url // empty') ``` For a squash-merge commit on the default branch, that returns the originating PR. For a direct commit it returns nothing. The job needs `pull-requests: read` for the lookup. We verified it against a real merge commit before trusting it rather than assuming the endpoint behaved as documented. This is the load-bearing gate. A commit that never went through review was never a candidate for the release history in the first place, whatever the deploy pipeline did with it. **Two, this revision is not already released.** Our tags carry a UTC timestamp, which means they never collide, which means a re-dispatch of the same commit happily mints a second release for a revision that already had one. That is precisely how four releases appeared for two revisions. So before minting, check the recent releases for one whose `target_commitish` already matches the deployed SHA, and skip if found. Both gates are cheap and bounded. The net effect is the one we wanted: dispatch as often as the work requires, and the Releases tab grows once per merged PR. ## The label that was quietly lying A smaller thing, worth naming because it is the kind of error that survives review. The deploy notification carried a link labelled `test run: passed`. The link pointed at the whole workflow run, which includes the test job and the deploy loop that actually shipped every worker. So the URL was right and the label was wrong: it framed the message as a test-status check when the reader is trying to learn whether the revision shipped. It now reads `deploy: succeeded`. Same URL, and the word stays literal, because the runner aborts on the first failing command and the line therefore never posts after a failed test or a failed worker deploy. We then found the same stale framing in the release body itself, still saying "test run" while the notification said "deploy". Two surfaces describing one event in two vocabularies is how people learn to distrust both. ## The question the gating created Gating releases behind merged PRs raises an obvious objection: if someone ships a small fix that never becomes a PR, how do we know what is actually running? Answer: not from releases at all. The deploy loop stamps the deployed commit onto every worker as a plain variable, and a script reads that back off the live platform API: ``` worker configs under workers/, env production workers/client/invoice df-client-invoice 5427cca... workers/contractor/payout df-contractor-payout 5427cca... workers/treasury/icy df-treasury-icy 5427cca... ... 5427cca... -> UNRELEASED, https://github.com/.../commit/5427cca... ``` This reads live state, not a deploy log, so it cannot drift. It answers "what is running right now" independently of whether a release exists, which is exactly the property that lets us gate releases aggressively without losing the incident-time answer. The `UNRELEASED` marker is the cross-reference we added afterwards: every distinct live commit is checked against the Releases tab, and if a live revision has no release, the script says so instead of printing a bare hash. In the run above that is correct and expected, because we had just cleared the polluted releases by hand. ## Push the warning, do not wait to be asked A pull-based script only helps someone who thinks to run it. The failure mode worth catching is the one nobody is looking for. Our deploy loop skips any worker whose config does not declare the target environment. That is deliberate, and it means a worker can sit on an older commit while everything around it moves forward, with nothing surfacing the fact. So the same script now runs inside the deploy step and its output is grepped for one line: ``` ⚠️ 3 distinct commits are live. The estate is not on one build. ``` Appended to the deploy notification only when there is drift. Never an all-clear on a clean deploy, because a line that appears every time stops being read. The finished notification: ``` 🚀 platform · production deploy #37 sha: a1b2c3d 📦 release: 20260812.153000 ⚙️ deploy: succeeded 📝 changes: * feat(payout): verify the Drive copy before commit-by-file flips Paid * fix(invoice): missing month paperwork no longer blocks generation ``` The changes list is not ours to generate. GitHub produces it when you pass `generate_release_notes: true` on release creation, and we read it back out of that same response instead of making a second call or parsing git log. Both links are masked markdown, which renders in a bot message's plain content even though Discord strips it from user-typed messages. ## What transfers The specifics are Cloudflare and GitHub Actions. The shape is not. **Deploy frequency and release frequency are different numbers, and agent-driven work makes the gap enormous.** Any pipeline that assumes they are equal will produce noise proportional to how productive the session was, which is a bad incentive. **Gate the record, not the action.** Slowing deploys to protect the release history would have been the wrong trade. Deploys are cheap and should stay cheap; the release is the thing that needs a meaning. **A version marker that reads live state beats one that reads a log.** The registry survived every change to the release policy precisely because it never depended on it. **Notifications should stay quiet when things are fine.** The drift line is valuable because it is rare. An all-clear on every deploy would train everyone to skip the message, and the one time it mattered they would. Five pull requests, one afternoon, most of it spent deleting things we had built earlier the same day. The reverted work was not wasted; a tag scheme keyed on the run number looked correct until we noticed re-runs reuse that number, and finding that out cost less than shipping it would have.

CAP breakdown

[Cap](https://github.com/CapSoftware/Cap) is an open-source, cross-platform screen recording system. It provides desktop and web apps for recording, editing, and sharing videos. All components are modular and can be self-hosted. ![demo](./assets/cap-instant-mode.gif) This documentation is a technical breakdown of Cap's Instant mode screen recording implementation. It describes the architecture, performance characteristics, and trade-offs made in the current implementation. ## Components Cap is organized as a monorepo with two main types of components: **Apps** — TypeScript/JavaScript applications that provide user interfaces and services: - **apps/web** — Next.js 14 web application (sharing, management, dashboard). - **apps/desktop** — Tauri v2 desktop app (recording, editing) with SolidJS. - **apps/tasks** — Background processing service for AI and post-processing. **Crates** — Rust libraries that handle performance-critical operations: - **crates/recording** — Core recording functionality and pipeline management. - **crates/camera\*** — Platform-specific camera capture implementations. - **crates/scap-\*** — Screen capture implementations (ScreenCaptureKit, Direct3D, etc.). - **crates/media-encoders** — Video/audio encoding modules with hardware acceleration. - **crates/rendering** — Video rendering and compositing engine. - **crates/editor** — Non-destructive editing system for advanced recording modes. - **crates/export** — Output generation in various formats (MP4, GIF, WebM). - **crates/cursor-capture** — Cursor movement and click tracking. This architecture separates performance-critical capture/processing (Rust) from user interface logic (TypeScript). Note: The architecture shows all available components. Instant mode uses a subset of these - specifically, it does not use the camera crate or the cursor-capture crate (which provides advanced cursor tracking for other modes). Instant mode embeds the cursor directly via OS APIs. ### Architecture The following diagram illustrates how these components interact in Cap's overall system architecture: ```mermaid flowchart TD subgraph CORE[Core Apps] desktop["apps/desktop (Tauri)"] web["apps/web (Next.js)"] tasks["apps/tasks (background)"] end subgraph DESKTOP_CAPTURE[Desktop Recording] recording["crates/recording"] scap["crates/scap-*"] camera["crates/camera-*"] cursorcapture["crates/cursor-capture"] audio["crates/audio"] end subgraph PROCESSING[Processing] encoder["crates/media-encoders"] editor["crates/editor"] export["crates/export"] rendering["crates/rendering"] end subgraph STORAGE[Storage] s3["S3-compatible storage"] database["Database (MySQL)"] end desktop --> recording recording --> scap recording --> camera recording --> cursorcapture recording --> audio recording --> encoder editor --> rendering editor --> export export --> s3 tasks --> s3 tasks --> database web --> database web --> s3 ``` ## Instant screen recording Having examined Cap's overall architecture, let's focus on how the instant recording mode leverages these components. Instant mode produces a single MP4 file that can be played immediately. While the file requires no post-processing for playback, standard MP4 editing tools can be used for trimming, cropping, or other modifications. This mode trades built-in editing features for reduced complexity and faster file availability. ### Recording flow The instant recording pipeline consists of three phases: ```mermaid flowchart LR subgraph INIT[Init] perm[Permissions] setup[Setup Encoders] end subgraph VIDEO[Video Pipeline] screen[Screen BGRA32] convert[→NV12] h264[H.264] end subgraph AUDIO[Audio Pipeline] sources[Mic + System] aac[AAC] end subgraph OUTPUT[Output] mux[MP4 Mux] file[MP4 File] end perm --> setup setup --> screen setup --> sources screen --> convert --> h264 --> mux sources --> aac --> mux mux --> file ``` #### Platform-specific capture implementation The recording flow begins with platform-specific implementations. Cap uses different native APIs for each platform to capture screen content and system audio, optimizing for performance and feature availability on each operating system. ```rust // crates/recording/src/sources/screen_capture/mod.rs #[cfg(windows)] mod windows; // Windows.Graphics.Capture #[cfg(target_os = "macos")] mod macos; // ScreenCaptureKit ``` **macOS (ScreenCaptureKit)**: - Unified API for screen + system audio - Native cursor compositing - Display stream capability up to 120fps (instant mode uses 30fps) - Typical latency: 16-20ms (measured via custom timestamps) **Windows (Windows.Graphics.Capture)**: - Direct3D11 capture pipeline - Separate WASAPI for audio loopback - Manual cursor rendering - GPU-accelerated color conversion Both platforms capture frames in BGRA32 format, which includes the desktop content and cursor. These raw frames must then undergo processing to prepare them for video encoding. ### Image recording Once captured from the platform APIs, the image recording subsystem handles pixel format conversion and resolution management, with cursor capture integrated directly into the screen capture process. ```mermaid flowchart TB subgraph MAC[macOS] sckit[Native Screen+Cursor] end subgraph WIN[Windows] d3d[Screen] --> composite[Composite] cursor[Cursor] --> composite end sckit --> frame[BGRA32 Frame] composite --> frame frame --> convert[→NV12] convert --> encode[H.264] ``` BGRA32 is the native GPU framebuffer format - when you see content on screen, it's stored in video memory as BGRA32 pixels (Blue, Green, Red, Alpha channels, 8 bits each). Both macOS and Windows capture APIs return frames in this format since it requires no conversion from the display buffer. NV12 is a YUV format that separates brightness (Y) from color (UV) information, using only 12 bits per pixel instead of BGRA32's 32 bits. This format matches how human vision works (more sensitive to brightness than color) and is required by H.264 encoders. H.264 is the video compression codec that reduces the video data by ~99% (from 248MB/s to 2.3MB/s) by encoding only the differences between frames and using perceptual compression techniques. The captured BGRA32 frames with embedded cursor must be converted to a format suitable for video encoding — a critical performance bottleneck optimized through GPU acceleration. #### Pixel format conversion The captured BGRA32 frames (with cursor already composited) undergo transformation: 1. **Native formats**: OS provides BGRA32 (GPU framebuffer format) 2. **Encoder requirements**: H.264 requires YUV color space (NV12) 3. **Bandwidth reduction**: - BGRA32: 32 bits/pixel (4 bytes) - NV12: 12 bits/pixel (1.5 bytes) - **Result**: 62.5% size reduction before encoding 4. **Performance at scale**: ``` 1080p@30fps BGRA32: 1920×1080×4×30 = 248.832 MB/s (237.3 MiB/s) 1080p@30fps NV12: 1920×1080×1.5×30 = 93.312 MB/s (89.0 MiB/s) ``` **GPU-accelerated conversion**: ```rust // crates/gpu-converters/src/nv12_rgba/mod.rs pub struct NV12ToRGBA { device: wgpu::Device, queue: wgpu::Queue, pipeline: wgpu::ComputePipeline, bind_group_layout: wgpu::BindGroupLayout, } ``` The conversion preserves cursor quality while maintaining color accuracy across the frame. #### Resolution strategy While capture happens at native resolution (including high-DPI displays), instant mode applies automatic downscaling when necessary: 1. **Capture resolution**: Always native display resolution - 5K iMac: 5120×2880 - 4K display: 3840×2160 - Ultrawide: 3440×1440 2. **Encoding resolution** (instant mode): - **Fixed**: Maximum 1080p (1920×1080) - **Frame rate**: Target 30fps (captures every 33.33ms, may reduce to 24fps under system stress) - **Downscaling**: Automatic if source > 1080p 3. **Downscaling pipeline**: - GPU compute shaders when available - Lanczos/bicubic filtering for sharp text - Cursor remains crisp during downscaling - Maintains even dimensions (H.264 requirement) While the video pipeline processes frames at 30fps intervals, audio data flows continuously from hardware sources — requiring its own parallel processing pipeline. ### Audio recording The audio recording subsystem operates concurrently with video capture, handling multiple responsibilities: 1. **Source management**: Captures from microphone and/or system audio with platform-specific APIs 2. **Audio mixing**: Combines multiple sources into a single stereo stream at 48kHz 3. **Buffering strategy**: Maintains elastic buffers to handle timing variations 4. **AAC encoding**: Compresses audio to 320 kbps constant bitrate #### Audio sources Instant mode supports two audio sources that can be used individually or combined: ```rust // Microphone audio (optional) if let Some(audio) = audio { let sink = audio_mixer.sink(*audio.audio_info()); let source = AudioInputSource::init(audio, sink.tx, SystemTime::now()); builder.spawn_source("microphone_capture", source); } // System audio (optional) if let Some(system_audio) = system_audio { audio_mixer.add_source(system_audio.1, system_audio.0); } ``` **Microphone capture**: - **Sample format**: Float32 PCM - **Sample rate**: 48kHz (industry standard for digital audio; resampled if necessary) - **Channels**: Mono or stereo based on device - **Buffer depth**: 64 slots for queuing (~83ms at 48kHz, balances latency vs. reliability) - **Processing**: Noise suppression available **System audio capture**: - **macOS**: Captured via ScreenCaptureKit alongside video - Zero additional latency - Synchronized with screen content - Requires screen recording permission only - **Windows**: WASAPI loopback capture (separate API) - ~10-20ms additional latency - Requires manual video alignment - May need additional permissions After capturing these audio sources, they must be combined into a single cohesive stream that matches the output requirements of the AAC encoder. #### Audio mixing The `AudioMixer` component takes the individual audio sources and combines them into a single unified stream: ```rust pub struct AudioMixer { sources: Vec, output_tx: Sender<(ffmpeg::frame::Audio, f64)>, } // Output configuration AudioInfo { sample_rate: 48000, // 48kHz: professional audio standard channels: 2, // Stereo output for spatial audio preservation } ``` **Mixing pipeline**: 1. **Input normalization**: All sources resampled to 48kHz 2. **Channel mapping**: - Mono mic → Stereo (duplicated to both channels) - Stereo system audio → Passthrough 3. **Level mixing**: Simple additive mixing (no compression) 4. **Overflow prevention**: Soft clipping at ±1.0 (prevents harsh digital distortion) The mixed audio now exists as a continuous stream of PCM samples, but a fundamental timing challenge emerges: audio flows continuously while video arrives in discrete 33.33ms frames. This mismatch necessitates sophisticated buffering. #### Audio buffering Audio buffering bridges the gap between continuous audio flow and discrete video timing. The buffer solves a fundamental mismatch: audio hardware produces samples continuously while video arrives in discrete frames (see [Audio-video synchronization](#audio-video-synchronization) for why video frames serve as the master clock), and must align with AAC format requirements for audio encoding. Without buffering, this mismatch would cause clicks, pops, and synchronization drift. **Buffer implementation**: ```rust pub struct AudioBuffer { pub data: Vec>, // Per-channel elastic queues pub frame_size: usize, // 1024 samples (AAC requirement) config: AudioInfo, } ``` The buffer operates elastically, growing and shrinking to accommodate timing variations while maintaining a target depth of 21-42ms (1-2 AAC frames). This balances low latency with protection against underruns during CPU spikes. **Key timing relationships**: - Audio hardware: Delivers samples in variable chunks (256, 512, etc.) - AAC encoder: Requires exactly 1024 samples per frame (21.3ms) - Video frames: Arrive every 33.33ms (≈1,600 audio samples) - Buffer: Accumulates samples and aligns both requirements With the audio samples properly buffered and aligned to frame boundaries, they're ready for compression. #### Audio encoding The final step in the audio pipeline transforms uncompressed PCM audio into AAC (Advanced Audio Coding), reducing file size by approximately 75% while maintaining perceptual quality. **Why AAC?** AAC was chosen as the audio codec for several technical reasons: 1. **Universal compatibility**: Works in all browsers, mobile devices, and video players 2. **MP4 standard**: Native audio format for MP4 containers (no remuxing needed) 3. **Compression efficiency**: Better quality than MP3 at same bitrate 4. **Low latency**: LC profile adds minimal encoding delay **Understanding audio compression**: ``` Uncompressed PCM audio (48kHz stereo): - Size: 48,000 samples × 2 channels × 4 bytes = 384 KB/second - Quality: Perfect reproduction - Problem: 23 MB/minute is too large for screen recordings AAC compression at 320 kbps: - Size: 320,000 bits ÷ 8 = 40 KB/second - Quality: Transparent to human hearing for most content - Result: 2.4 MB/minute (83.3% size reduction) ``` **Encoding configuration**: ```rust // AAC encoder configuration const OUTPUT_BITRATE: usize = 320 * 1000; // 320 kbps (high quality, ~2.4MB/min) const SAMPLE_FORMAT: Sample = Sample::F32(Type::Planar); ``` Note: 320 kbps chosen for maximum compatibility while maintaining high quality. Variable bitrate (VBR) could reduce file size by 20-30% but was avoided due to compatibility concerns with some video players and streaming services. **Quality considerations**: - 320 kbps provides transparency for most content (comparable to streaming services) - Voice remains clear even with background music - System sounds preserved without artifacts - Suitable for professional presentations The audio pipeline — from capture through mixing, buffering, and encoding — now produces a high-quality AAC stream running in parallel with the H.264 video stream. However, these independent streams must maintain perfect temporal alignment to create a cohesive viewing experience. ### Audio-video synchronization Synchronizing separate audio and video streams represents one of the most critical technical challenges in screen recording. Human perception is remarkably sensitive to A/V misalignment — timing errors exceeding 40ms are immediately noticeable and significantly degrade the viewing experience. **Real-world example**: Imagine recording a balloon pop ``` What happens without proper sync: ┌─────────────┬─────────────┬─────────────┬──────────┬───────────┐ │ 0ms │ 33ms │ 66ms │ 100ms │ 133ms │ ├─────────────┼─────────────┼─────────────┼──────────┼───────────┤ │ Video: │ Pin touches │ Balloon │ Balloon │ Pieces │ │ │ balloon │ deforming │ bursting │ flying │ ├─────────────┼─────────────┼─────────────┼──────────┼───────────┤ │ Audio │ (silence) │ (silence) │ (silence)│ "POP!" │ │ (50ms late):│ │ │ │ │ └─────────────┴─────────────┴─────────────┴──────────┴───────────┘ Result: The pop sound occurs after the balloon has already burst, breaking the cause-effect relationship. With proper sync: ┌────────┬─────────────┬─────────────┬─────────────┬─────────────┐ │ 0ms │ 33ms │ 66ms │ 100ms │ 133ms │ ├────────┼─────────────┼─────────────┼─────────────┼─────────────┤ │ Video: │ Pin touches │ Balloon │ Balloon │ Pieces │ │ │ balloon │ deforming │ bursting │ flying │ ├────────┼─────────────┼─────────────┼─────────────┼─────────────┤ │ Audio: │ (silence) │ (silence) │ "POP!" │ (echo) │ └────────┴─────────────┴─────────────┴─────────────┴─────────────┘ Result: Sound aligns perfectly with the visual burst ``` #### The synchronization challenge Multiple factors make A/V sync difficult in screen recording: **Independent hardware clocks**: ``` Video clock: Display refresh (60Hz, 120Hz, etc.) Audio clock: Sample rate oscillator (48kHz ± 0.01%) System clock: CPU high-resolution timer Drift example over 1 hour: - Video: 30fps × 3600s = 108,000 frames expected - Audio: 48000Hz × 3600s = 172,800,000 samples expected - With 0.01% clock drift: 17,280 sample difference = 360ms desync - Cap's correction: Maintains <40ms offset through elastic buffering ``` **Variable capture latencies**: - Screen capture: 5-20ms (varies by GPU load) - Microphone: 10-50ms (depends on buffer size) - System audio: 20-100ms (especially on Windows) - Network cameras: 100-500ms (USB/compression delays) #### Master clock architecture Cap uses a video-driven master clock design: ```rust // Instant recording timing struct InstantRecordingActorState { segment_start_time: f64, // Wall clock reference // Video frames provide timing heartbeat } // Fixed video frame intervals const FRAME_DURATION_30FPS: f64 = 1.0 / 30.0; // 33.33ms ``` **Why video as master?** 1. **Predictable intervals**: Exactly 33.33ms per frame 2. **User expectation**: Dropped audio less noticeable than frozen video 3. **Simpler pipeline**: Audio can adapt buffer size, video cannot 4. **Display sync**: Aligns with monitor refresh rate #### Timestamp management Each media source maintains its own timestamps, which must be correlated: ```rust // Video timestamp (from capture) video_pts = capture_time - recording_start_time // Audio timestamp calculation audio_pts = sample_position / sample_rate // But must align to video frames: aligned_audio_pts = round(audio_pts / FRAME_DURATION) * FRAME_DURATION ``` **Dual timestamp system**: ```rust // Wall clock for absolute reference segment_start_time: f64 // Unix timestamp // Monotonic clock for relative timing let elapsed = Instant::now() - start_instant; let pts = elapsed.as_secs_f64(); ``` This prevents system clock adjustments from causing sync issues. #### Elastic buffer synchronization The audio buffer adapts elastically to maintain synchronization with video timing: ```rust impl AudioBuffer { fn read_frame(&mut self, video_pts: f64) -> Option { let target_samples = self.samples_for_video_pts(video_pts); if self.available_samples() < target_samples * 0.8 { // Underrun: repeat samples or insert silence self.handle_underrun(target_samples) } else if self.available_samples() > target_samples * 1.2 { // Overrun: drop oldest samples self.handle_overrun(target_samples) } else { // Normal operation self.read_samples(target_samples) } } } ``` **Example: Processing balloon pop audio** ``` Video Frame 1 (0ms): Need 1,600 audio samples for 33.33ms ├─ Buffer has 1,500 samples of silence ├─ Status: Underrun (93%) └─ Action: Duplicate last 100 samples to fill gap Video Frame 2 (33ms): Need next 1,600 samples ├─ Buffer has 1,650 samples (silence + pop beginning) ├─ Status: Normal (103%) └─ Action: Read exactly 1,600 samples Video Frame 3 (66ms): Need next 1,600 samples ├─ Buffer has 2,100 samples ("POP!" sound) ├─ Status: Overrun (131%) └─ Action: Drop oldest 500 samples to stay in sync ``` The buffer maintains synchronization through gradual adjustments, using 80%/120% thresholds to trigger corrections while avoiding audible artifacts. #### Platform-specific synchronization **macOS (Unified capture)**: ```objc // ScreenCaptureKit provides synchronized timestamps SCStreamHandler { didOutputVideoFrame: (frame, timestamp) { // Video and audio share same time base video_pts = CMTimeGetSeconds(timestamp) } didOutputAudioData: (data, timestamp) { audio_pts = CMTimeGetSeconds(timestamp) // Timestamps are pre-synchronized by the OS } } ``` **Windows (Separate APIs)**: ```rust // Manual synchronization required let capture_delay = estimate_capture_latency(); let audio_delay = measure_wasapi_latency(); // Correlate using system clock video_pts = video_capture_time - recording_start; audio_pts = audio_capture_time - recording_start - (audio_delay - capture_delay); ``` #### Synchronization quality metrics The pipeline monitors sync quality in real-time: ```rust struct SyncMetrics { avg_offset: f64, // Running average offset max_offset: f64, // Worst case seen drift_rate: f64, // ms/minute corrections: u32, // Number of adjustments } // Acceptable thresholds const MAX_SYNC_ERROR: f64 = 0.040; // 40ms const DRIFT_THRESHOLD: f64 = 0.001; // 1ms/minute ``` **Sync preservation strategies**: 1. **Frame dropping policy**: Drop P-frames first, preserve I-frames for seeking 2. **No resampling**: Avoid audio quality loss 3. **Minimal correction**: Small, gradual adjustments (<5ms per second) 4. **Early detection**: Monitor drift continuously When frames must be dropped: - P-frames dropped first (minimal visual impact) - I-frames preserved to maintain seekability - Audio never dropped (more noticeable than video drops) #### Muxer synchronization The MP4 muxer enforces final synchronization by interleaving audio and video data: ```rust // Interleaving based on DTS (Decode Time Stamp) loop { let next_video = video_queue.peek(); let next_audio = audio_queue.peek(); match (next_video, next_audio) { (Some(v), Some(a)) => { if v.dts <= a.dts { write_video_sample(v)?; video_queue.pop(); } else { write_audio_sample(a)?; audio_queue.pop(); } } (Some(v), None) => { write_video_sample(v)?; video_queue.pop(); } (None, Some(a)) => { write_audio_sample(a)?; audio_queue.pop(); } (None, None) => break, } } ``` **Example: Muxing the balloon pop sequence** ``` Queue state during muxing: ┌──────────────────────────────────────────────────────────────┐ │ Video Queue: [V0:0ms] [V1:33ms] [V2:66ms] [V3:100ms] │ │ Audio Queue: [A0:0ms] [A1:21ms] [A2:42ms] [A3:64ms] [A4:85ms]│ └──────────────────────────────────────────────────────────────┘ Muxing order (by timestamp): 1. Write V0 (0ms) - Pin touches balloon 2. Write A0 (0ms) - Silence 3. Write A1 (21ms) - Silence 4. Write V1 (33ms) - Balloon deforming 5. Write A2 (42ms) - Silence 6. Write A3 (64ms) - "POP!" begins 7. Write V2 (66ms) - Balloon bursting 8. Write A4 (85ms) - "POP!" peak 9. Write V3 (100ms) - Pieces flying Result: Synchronized playback with pop sound aligned to burst ``` ![cap-muxing](./assets/cap-muxing.png) **Edit lists for start alignment**: ``` // If audio starts 50ms late: Video track: [edts] media_time=0, duration=full Audio track: [edts] media_time=50ms, duration=full-50ms ``` This aligns playback start for both tracks. With both streams properly synchronized, they must be combined into a single file that maintains this timing relationship during playback. ### MP4 muxing implementation The muxing process combines the synchronized audio and video streams into a standard MP4 container. The `MP4AVAssetWriterEncoder` carefully interleaves the streams while preserving their temporal relationships, creating an MP4 file with the following structure: 1. **File type box (ftyp)**: ``` - Major brand: mp42 - Compatible brands: mp42, isom - Version: 0 ``` 2. **Media data box (mdat)**: - Interleaved samples in decode order - Chunk-based organization - No random access without moov 3. **Movie box (moov)**: - **mvhd**: Movie header (duration, timescale) - **trak** (video): - tkhd: Track header - mdia/minf/stbl: Sample tables - stts: Sample timing - stss: Sync samples (keyframes) - stco: Chunk offsets - **trak** (audio): - Similar structure for AAC track 4. **Faststart optimization**: ``` Initial: [ftyp][mdat][moov] Final: [ftyp][moov][mdat] // Enables progressive download ``` The faststart optimization repositions metadata to enable progressive playback during download — a crucial feature for web sharing. ### Encoding configuration Throughout the recording pipeline, Cap must balance quality with real-time performance constraints. The system uses FFmpeg's codec support with carefully tuned parameters: ```rust // Hardware encoder selection priority 1. VideoToolbox (macOS) 2. NVENC (NVIDIA) 3. QuickSync (Intel) 4. AMF (AMD) 5. Software x264 (fallback) ``` **H.264 parameters**: - **Preset**: "ultrafast" (optimized for real-time) - **Profile**: High (when supported by hardware encoder, falls back to Main) - **Level**: Auto (based on resolution) - **B-frames**: 0 (reduce latency) - **Reference frames**: 3 - **Rate control**: Calculated based on resolution (≈18.7 Mbps for 1080p@30fps) **AAC parameters**: - **Sample rate**: 48 kHz - **Bitrate**: 320 kbps - **Channels**: Stereo when available, mono fallback - **Profile**: AAC-LC (Low Complexity) These encoding parameters reflect extensive tuning to balance output quality with the stringent performance requirements of real-time capture. ### Performance characteristics The careful optimization throughout the pipeline results in the following measured resource usage: | Component | CPU Usage\* | Memory | Notes | | -------------- | ----------- | ------ | ----------------------- | | Screen capture | 1-3% | 20MB | OS-handled | | BGRA→NV12 | 2-5% | 50MB | GPU when available | | H.264 encode | 3-8% | 80MB | Hardware accelerated | | AAC encode | 1-2% | 10MB | Hardware when available | | MP4 muxing | <1% | 5MB | Sequential writes | \*CPU percentages are estimates and due to parallel execution and shared resources, individual components may not sum to the total in actual measurement. **Throughput metrics**: - 1080p@30fps: ~248.8 MB/s raw → 18.7 Mbps encoded - Audio: 1.5 Mbps raw → 320 kbps encoded These modest resource requirements enable smooth concurrent operation with other applications on typical hardware — a key design goal for a tool meant to record other software in action. ### Error handling Real-world recording scenarios present numerous failure modes — from permission issues to resource exhaustion. The instant mode pipeline implements comprehensive error recovery strategies across all components, prioritizing recording continuity over perfect quality when failures occur. Errors are logged to system telemetry (when enabled) with the following metrics: - `dropped_frames_count` - `audio_underrun_count` - `encoder_fallback_count` - `sync_correction_count` - `disk_space_warnings` #### Permission & initialization errors **Screen recording permission denied**: ```rust // macOS: Direct user to System Preferences // Windows: Retry with fallback to BitBlt API match check_screen_permission() { Err(PermissionDenied) => { show_permission_dialog(); return Err("Screen recording requires permission"); } Ok(_) => continue, } ``` **Audio device unavailable**: ```rust // Continue recording without audio rather than failing match init_microphone() { Err(_) => { log_warning("Microphone unavailable, continuing without audio"); None } Ok(mic) => Some(mic), } ``` #### Runtime capture errors **Frame drops and recovery**: ```rust // Monitor frame timing and adapt if elapsed > FRAME_DURATION * 1.5 { // Missed frame deadline stats.dropped_frames += 1; if stats.dropped_frames > 10 { // Persistent issues - reduce capture rate reduce_framerate_to_24fps(); } } else { // Reset counter on successful capture stats.dropped_frames = 0; } ``` **Encoder failures with fallback chain**: ``` 1. Try hardware encoder (VideoToolbox/NVENC) ↓ Fails (GPU overloaded) 2. Try alternative hardware (QuickSync) ↓ Fails (not available) 3. Fall back to software x264 ↓ Fails (CPU overloaded) 4. Reduce resolution to 720p and retry ↓ Success - continue recording ``` #### Resource management **Disk space monitoring**: ```rust // Check available space every second fn monitor_disk_space(&self) -> Result<()> { let available = get_free_space(&self.output_path)?; match available { 0..=100_000_000 => { // <100MB self.stop_recording(); Err("Insufficient disk space") } 100_000_000..=500_000_000 => { // 100-500MB (0.7-3.5 minutes at 142.7MB/min) self.show_warning("Low disk space"); self.reduce_quality(); // Switch to lower bitrate Ok(()) } _ => Ok(()) // Sufficient space } } ``` **Memory pressure handling**: ```rust // Adapt buffer sizes based on available memory let buffer_size = match available_memory() { 0..=1_000_000_000 => 32, // <1GB: minimal buffers 1_000_000_000..=4_000_000_000 => 64, // 1-4GB: standard _ => 128, // >4GB: larger buffers }; ``` #### Synchronization recovery **Audio drift correction**: ```rust // Detect and correct audio/video drift if audio_pts - video_pts > MAX_DRIFT { // Audio running ahead audio_buffer.drop_samples(drift_samples); log_event("Dropped {} audio samples to maintain sync", drift_samples); } else if video_pts - audio_pts > MAX_DRIFT { // Video running ahead audio_buffer.insert_silence(drift_samples); log_event("Inserted {} silence samples to maintain sync", drift_samples); } ``` #### Graceful degradation priority When multiple errors occur, the system follows this degradation hierarchy: 1. **Maintain recording** - Never stop unless critical failure 2. **Preserve video** - Drop audio before dropping video 3. **Reduce quality** - Lower resolution/framerate before failing 4. **Simplify pipeline** - Disable effects, cursor, etc. 5. **Alert user** - Clear indication of degraded state **Example cascade**: ``` Normal: 1080p30 + audio + cursor → 142.7MB/min Degraded 1: 1080p24 + audio + cursor → 115MB/min (thermal throttle) Degraded 2: 720p24 + audio + cursor → 65MB/min (memory pressure) Degraded 3: 720p24 + no audio → 60MB/min (audio failure) Emergency: 480p15 + no audio → 20MB/min (critical resources) ``` This comprehensive error handling strategy ensures recordings continue even under adverse conditions, with graceful degradation that users can understand. **User-facing error states**: - Recording indicator changes color (green→yellow→red) - Toast notifications for degraded quality - Final recording includes metadata about any quality reductions ### Constraints & trade-offs Every engineering decision involves trade-offs. Instant mode's design choices prioritize simplicity, immediate availability, and low resource usage — but these benefits come with specific limitations. #### Feature constraints **What instant mode CANNOT do**: | Feature | Why It Is Excluded | Impact | | --------------------- | ----------------------------------------- | --------------------------------------------- | | Camera overlay | Requires real-time compositing (+30% CPU) | No picture-in-picture presentations | | Cursor customization | Cursor baked into frames during capture | Cannot enhance or hide cursor after recording | | Pause/resume | Implementation choice for simplicity\* | Must stop and start new recording | | Variable quality | Encoders locked during capture | Quality decisions must be made upfront | | Built-in editing | Not included in instant mode\*\* | Use Studio mode or external tools | | Multiple audio tracks | Single AAC stream in MP4 | Cannot separate mic/system audio later | \*MP4 supports pause/resume through segment concatenation or edit lists, but instant mode prioritizes one-click simplicity over complex timeline management. \*\*The MP4 files produced by instant mode are standard format and fully compatible with video editing software (FFmpeg, Adobe Premiere, DaVinci Resolve, etc.). Instant mode omits built-in editing features to maintain simplicity and reduce complexity. #### Technical trade-offs **Performance vs. Flexibility**: ``` Cap Instant Mode: Traditional Screen Recorders (OBS, etc.): ├─ Single encoding pass ├─ Capture raw → encode → remux ├─ Direct-to-MP4 muxing ├─ MKV/FLV → convert to MP4 ├─ 5-15% CPU usage (typical) ├─ 20-40% CPU usage ├─ 165MB memory ├─ 400MB+ memory ├─ Direct MP4 output ├─ Intermediate format → MP4 └─ Ready in <100ms └─ Ready in 5-30 seconds ``` **Quality vs. File Size**: - **Current**: 1080p30 @ 18.7 Mbps video + 320 kbps audio = 142.7 MB/minute - **Alternative 1**: 4K30 @ 50 Mbps video + 320 kbps audio = 377.4 MB/minute (2.6x larger) - **Alternative 2**: 1080p60 @ 25 Mbps video + 320 kbps audio = 189.9 MB/minute (1.3x larger) - **Decision**: 1080p30 balances quality with reasonable file sizes #### Design philosophy The constraints reflect three core principles: 1. **Immediate availability** - No waiting for processing - No intermediate files - Direct upload capability 2. **Universal compatibility** - Standard MP4 container - H.264/AAC codecs work everywhere - No special players required 3. **Predictable performance** - Consistent resource usage - No surprise CPU spikes - Works on modest hardware #### Ideal use cases **Instant mode excels at**: - Short demos and explanations (1-10 minutes) - Bug reports and issue documentation - Meeting recordings and presentations - Social media content (sub-5 minute videos) - Live troubleshooting sessions - Educational content without heavy editing needs **Instant mode struggles with**: - Long recordings (>30 minutes due to file size) - Content requiring post-production - Multi-camera or complex audio setups - Recordings needing precise editing - Ultra-high quality requirements (4K/60fps) These deliberate trade-offs create a tool optimized for a specific workflow: users who need to record and share screen content quickly without post-processing requirements. ## Summary This technical breakdown has traced the complete journey of a screen recording through Cap's instant mode pipeline — from initial permission checks to final MP4 output. The implementation demonstrates how careful architectural choices enable high-quality screen recording with minimal system impact. Cap's instant screen recording mode leverages platform-native APIs, GPU acceleration, and sophisticated synchronization mechanisms to achieve: - **One-click recording** with no configuration required - **Low resource usage** (5-10% CPU on M1 Max, 10-15% on i7-12700K) - **Immediate sharing** with standard MP4 output - **Professional quality** at 1080p30 with synchronized audio - **Cross-platform consistency** between macOS and Windows The single-pass architecture deliberately trades post-processing flexibility for reduced latency and simplified implementation. Every component — from platform-specific capture APIs to elastic audio buffers to synchronized muxing — serves the core design goals of immediate file availability, universal playback compatibility, and predictable resource usage. This architectural approach positions Cap's instant mode as an ideal solution for modern screen recording needs, where the ability to quickly capture and share content often outweighs the need for complex editing features. --- _Disclaimer: Additional appendices covering Performance Measurement Methodology, Platform Support & Limitations, Security & Privacy Considerations, and Known Issues have been excluded from this document to keep it focused on the core technical implementation._

Social proof

> **tl;dr** > Clients only buy from people who have already done the thing. If you haven't done the thing, you manufacture the appearance of having done it; truthfully, cheaply, and fast. ## The catch-22 Clients only buy from people who have already done the thing. If you haven't done the thing, you don't get clients. If you don't get clients, you never do the thing. The loop is brutal and most people spend years trying to break it the "fair" way; sending cold pitches with zero credibility and wondering why no one replies. The economy does not reward playing fair; it rewards playing well. Below are three ways to play well. ## 1. Monetary association claim **Rule:** never lead with the artifact you built; lead with the money it moved. | Weak claim | Strong claim | | --------------------------------------- | ------------------------------------------------------------ | | Built a marketing system for XYZ agency | Generated $15k in two weeks through a marketing system | | Wrote a React component library | Reduced page-load cost by $8k/mo with a component library | | Did a summer internship at a fintech | Saved a fintech $120k annually by pruning dead features | If you don't have direct revenue numbers, borrow them: - "Built the same checkout flow that powers $50M of Shopify GMV." - "Deployed the same fraud model that caught $3M in attempts at Stripe." The dollar sign is the universal language; everything else is dialect. ## 2. Team association principle You do not need to have worked _for_ Google; you only need to have worked _with_ someone who works at Google. 1. Pick a big-name company in your niche. 2. On LinkedIn, filter for non-executive employees (they say yes more often). 3. Offer a micro-deliverable worth ≥ $500: scrape their last ten posts and write ten more in their tone, build a Notion dashboard, audit their landing page Core Web Vitals; anything that takes you < 1 day but saves them > 1 hour. 4. Deliver, then add one line to your bio: "Have delivered value for people on the Google Ads team." Use the qualifier "members of" or "people at" so the claim stays truthful. The brand rubs off; the objection "Has this person done the thing?" disappears. ## 3. Overflow contractor method When you have neither money nor logos, trade _leads_ for _logos_. 1. Buy or scrape 50 qualified leads you cannot yet service. 2. Cold-call niche agencies: "I have leads I can't fulfill; want them for 15% referral?" 3. Sign a one-page referral agreement that lets you list them as "team members." 4. Now your site can truthfully say: "Our videographers have shot for Gillette, Pfizer, and three Fortune 500s." You are not claiming you shot the spots; only that _members of your extended team_ did. The prospect's brain hears the brands and stops asking questions. ## Compound interest Each tactic above is interest-bearing. Stack them: - Week 1: land two monetary claims worth $40k combined. - Week 3: add a Microsoft association. - Week 6: overflow five agencies and inherit their client list. After 60 days you can write: "I've helped teams that have generated over $1M in new revenue and worked with people at Microsoft, Shopify, and Stripe." All technically true, all acquired with time instead of track record. ## Ethics guardrails - Never claim you _worked for_ a company when you only worked _with_ an employee. - Never invent dollar figures; associate with existing ones. - Always deliver the free value you promised; reputation compounds faster than any hack. Social proof is not a static asset; it is a resource you manufacture by strategically trading time, value, and language. Start today and you can buy yourself a million dollars of credibility before the quarter ends. --- > Next: [Test the water](test-the-water.md)

How knowledge work organizes itself

## It is what it is To be honest, both you and I would be useless time travelers: There is something implicit on how knowledge works naturally to organize itself, not by ideology or planning, but by computational necessity. We don't really want to overload our brains learning everything. Conversely, we don't want to be a product of our own ignorance. Each approach represents a different relationship with [knowledge compression and fidelity](the-five-stages-of-learning.md). You end up with 3 personas: ## Operators: those who apply compressed rules ![operators](./assets/operators.webp) Most people in knowledge work apply socially bootstrapped knowledge without necessarily understanding the underlying principles. A software developer using React doesn't need to understand virtual DOM diffing algorithms; they need to know that components re-render when state changes. These knowledge workers rely on compressed heuristics; fuzzy rules of thumb that usually work. "Redux for complex state management," "use TypeScript for large projects," "follow the Airbnb style guide." These aren't derived from first principles but transmitted socially, like folklore. The power of this approach lies in scale. When thousands of developers use the same compressed abstractions, they can coordinate massive projects. The cost is brittleness. When the underlying assumptions shift; when the virtual DOM model no longer fits the problem space; the entire edifice can crumble. Consider how medical knowledge operates. General practitioners diagnose common conditions using diagnostic flowcharts and established protocols. They don't derive treatment plans from molecular biology; they apply socially transmitted knowledge that "strep throat gets amoxicillin." This enables them to see dozens of patients daily; but leaves them vulnerable when encountering rare diseases that don't fit the patterns. **Why they are foundationally important**: **Society needs billions applying compressed rules to coordinate massive projects. Without operators, we couldn't build or maintain civilization at scale.** ## Adapters: those who connect the dots ![adapters](./assets/adapters.webp) Some knowledge workers recognize when heuristics break down and adjust them without reverting to first principles. A senior engineer debugging a complex system doesn't need to understand every component; they can recognize that "this performance issue looks like that memory leak we saw last quarter, except the symptoms are slightly different." These workers excel at analogical reasoning and tinkering; mapping problems across domains. When the standard microservices architecture starts failing at scale; they don't rebuild from scratch. They borrow patterns from distributed systems theory, adjust them pragmatically. and iterate quickly based on feedback. The strength of this approach is resilience. When COVID-19 disrupted supply chains; operations managers didn't redesign global logistics from base principles. They adapted existing just-in-time systems to handle sudden demand spikes; borrowed patterns from disaster response protocols, and improvised solutions that kept essential goods flowing. In medicine, specialists adapt treatment protocols for rare conditions. An oncologist treating an unusual cancer doesn't start from molecular biology; they adapt existing chemotherapy protocols, borrowing patterns from similar cancers, and adjusting based on patient response. This keeps systems functional under moderate change without requiring complete redesign. **Why you need them**: **Systems need resilience when assumptions break; adapters prevent total collapse by bridging old rules to new realities without starting from scratch.** ## Explorers: those who derive new principles ![explorers](./assets/explorers.webp) A minority deliberately abandon compressed heuristics to reconstruct from base constraints. When the existing abstractions collapse, when distributed systems theory can't handle the scale, when standard cancer treatments stop working; they burn down the scaffolding and rebuild from ground truth. These researchers operate on first-principles thinking. A scientist developing mRNA vaccines didn't adapt existing vaccine technology but derived new therapeutic approaches from molecular biology. When traditional chemotherapy reached its limits, researchers developed CAR-T cell therapy by understanding immune system mechanisms at the cellular level. The value of this approach emerges at discontinuities. When compressed knowledge fails catastrophically, when financial models collapse during market crashes, when software architectures crumble under unexpected load; they provide the new foundations that enable the cycle to begin again. **Why you should have at least 1 bro for this**: **Civilization needs first-principles thinkers to derive new foundations when compressed knowledge catastrophically fails. Without them; the world would be pretty boring, and be straight up less innovative.** ## The equilibrium dynamics This is an intentionally unbalanced system. Civilizations need many people applying compressed rules for scale, some recognizing when rules break for resilience, and few deriving new principles for renewal. The knowledge flows in cycles: researchers derive new principles from first principles, others compress these into usable heuristics, and most apply them at scale. When environmental conditions shift; when the underlying assumptions that compressed knowledge relies upon no longer hold; the cycle accelerates. The 2008 financial crisis forced researchers to derive new economic models; others to compress these into regulatory frameworks; and most to apply new risk management protocols. ## Implications for AI development Understanding this organization suggests that AGI development won't eliminate these approaches, but will augment them. AI will handle routine and basic heuristic application, assist in pattern transfer, and accelerate hypothesis generation. Unlike the consultants that tout that AI would replace every one, **AI replaces no one here**. What it does give us is more [*leverage*](https://www.indiehackers.com/post/lifestyle/the-leverage-paradox-ksRiX6y6W7NzfBE57dzt) at each part of the system.

The five stages of learning

## The cognitive continuum When a child first learns that a hot stove burns, the lesson arrives as immediate sensation rather than understanding. This moment captures the earliest stage of learning - forming simple associations between stimuli and responses without grasping why these connections matter. The same process occurs when a neural network first learns to recognize edges in pixels. Both represent the beginning of a journey that biological and artificial systems undertake toward increasingly sophisticated understanding. This progression from surface pattern recognition to deep understanding follows a predictable path across both human development and artificial intelligence. Rather than distinct categories, these stages represent a continuum where each level builds upon the previous, trading specificity for generality while maintaining essential features through compression. ![the-five-stages-of-learning](./assets/the-five-stages-of-learning.webp) ## Stage one: associative learning Picture a toddler reaching toward a glowing burner. The lesson is immediate and visceral - hot surface equals pain. There's no understanding of thermal conductivity or heat transfer, just a simple association burned into memory. This represents the foundation where both humans and early AI systems form basic stimulus-response mappings without underlying comprehension. In artificial systems, this mirrors the earliest perceptrons and simple neural networks that could learn linearly separable patterns but failed at anything requiring deeper abstraction. The representations remain shallow, the generalization minimal, but the learning immediate and energy-efficient. ## Stage two: procedural learning Consider learning to ride a bicycle. At first, every movement requires conscious attention - balance, pedaling, steering. Through repetition, these actions become automatic. The knowledge moves from explicit to implicit, from conscious effort to muscle memory that operates below awareness. This mirrors how reinforcement learning agents master specific tasks through countless iterations. A robotic arm learns to grasp objects not by understanding physics, but through trial and error that gradually refines its movements. The expertise becomes context-dependent, difficult to articulate, but deeply internalized. ## Stage three: conceptual learning When students learn that grammar governs how words combine to form meaning, they're moving beyond simple associations to extract rules and categories. This enables symbolic reasoning - understanding that "the cat sat on the mat" follows grammatical rules regardless of whether an actual cat is involved. In AI systems, this corresponds to classical expert systems where humans manually designed features to capture relevant patterns. The knowledge becomes explicit, transferable across domains, but requires conscious effort to apply. ## Stage four: metacognitive learning Watch a skilled researcher develop new study techniques. They're not just learning content but learning how to learn. They reflect on their learning process, adjust strategies based on what works, and transfer these strategies across domains. This mirrors meta-learning algorithms that learn how to optimize their own learning processes. The focus shifts from specific content to general learning strategies that adapt to new domains without starting from scratch. ## Stage five: deep learning Consider an experienced physician who can glance at a patient's symptoms and immediately sense something is wrong, even when the presentation is atypical. This intuition emerges from years of experience compressed into hierarchical abstractions that operate below conscious awareness. This represents the pinnacle of both human expertise and artificial intelligence - systems that automatically discover multi-level representations without explicit feature design. The compression is massive, the fidelity maintained through hierarchical abstraction, and the processing occurs beyond what can be explicitly articulated. ## The compression-fidelity trade-off Each stage represents a systematic trade-off between how much information we compress versus how accurately we maintain essential features. Early stages preserve maximal fidelity to specific instances with minimal compression. Later stages achieve massive compression while maintaining predictive power through hierarchical abstraction. This explains why most human cognition operates on compressed heuristics rather than first-principles reasoning. It's computationally efficient, not necessarily more accurate. We navigate daily life using fuzzy rules of thumb rather than deriving everything from base principles because the cognitive load would be unsustainable. ## Practical implications Understanding these stages illuminates why experts often cannot articulate their intuition, why teaching requires moving up and down the hierarchy, and why human learning remains more efficient than current AI training. The progression isn't linear; humans and advanced AI systems operate across multiple stages simultaneously, using the appropriate level of abstraction for each context. > Next: [How knowledge work organizes itself](how-knowledge-work-organizes-itself.md)

Stagehand breakdown

**Stagehand** a browser automation framework that fundamentally redefines how we approach web interaction programmatically. Developed by Browserbase, Stagehand successfully bridges the long-standing gap between the brittleness of traditional automation tools and the unpredictability of pure AI agents. This innovation allows developers to seamlessly blend deterministic code with natural language instructions, achieving unparalleled resilience and adaptability in automation workflows. ![demo](./assets/stagehand.gif) Stagehand offers several advantages over conventional methods: - **Enhanced resilience:** Adapts automatically to website changes, significantly reducing maintenance overhead. - **AI-powered adaptability:** Integrates natural language processing for flexible, intent-driven automation. - **Production readiness:** Provides the predictability and control essential for enterprise-grade systems. - **Cost optimization:** Intelligently manages LLM usage to minimize operational expenses. ## What stagehand does Stagehand is a TypeScript/JavaScript framework that transforms browser automation from a fragile, maintenance-heavy process into a resilient, AI-enhanced workflow that adapts to website changes automatically. It provides three core modes of browser interaction, allowing developers to combine the precision of traditional Playwright code with the flexibility of natural language instructions: - **AI actions (`page.act()`):** Enables natural language-driven browser actions. For instance, `await page.act("click the login button")` allows Stagehand to intelligently find and interact with the correct element, even on dynamic or unfamiliar interfaces, without relying on brittle selectors. - **Data extraction (`page.extract()`):** Facilitates structured data retrieval. Developers can provide natural language instructions along with a Zod schema, and Stagehand will extract the relevant data from the page, ensuring type safety and validation. This is ideal for content scraping or extracting form data. - **Element analysis (`page.observe()`):** Provides AI-powered element identification and analysis. This method helps in understanding the page structure, identifying specific elements (e.g., `await page.observe("find all buttons")`), and can be used for debugging or gaining insights into a web page's interactive components. Beyond these core AI-enhanced methods, Stagehand also integrates an **Agent System** for multi-step autonomous browser automation. This system allows for high-level instructions (e.g., `agent.execute("find all available apartments with floor plans")`) to be broken down into a sequence of AI-driven and programmatic browser actions, enabling complex workflows that would traditionally require extensive, brittle code. The framework integrates with major LLM providers (OpenAI, Anthropic, Google) and supports both local Playwright browsers and cloud browsers via Browserbase. ## How stagehand operates under the hood Stagehand's core innovation lies in its **hybrid intelligence architecture**, which combines Playwright's reliability with advanced AI capabilities. This hybrid approach allows developers to seamlessly mix traditional, deterministic automation code (e.g., precise CSS selectors for stable elements) with flexible, AI-driven natural language instructions (e.g., "click the submit button" for dynamic elements). This strategic blend ensures that automation scripts are both resilient to UI changes and maintain the predictability and control required for production systems. We leverage several key architectural pillars to deliver this unique functionality: ### Overall system architecture ```mermaid graph TB subgraph "User Interface Layer" DEV[Developer Code] NL[Natural Language Instructions] SCHEMA[Zod schemas] end subgraph "Stagehand Core" API[Stagehand API Layer] ATOMIC[Atomic Primitives] AGENT[Agent Orchestrator] CACHE[Action cache] ATOMIC --> ACT[act<>] ATOMIC --> EXTRACT[extract<>] ATOMIC --> OBSERVE[observe<>] end subgraph "Intelligence Layer" LLM[Multi-Model LLM Provider] OPENAI[OpenAI] ANTHROPIC[Anthropic] GEMINI[Gemini] LOCAL[Local Models] end subgraph "Browser Layer" PW[Playwright Core] A11Y[Accessibility Tree] CDP[Chrome DevTools Protocol] BROWSER[Browser Instance] end subgraph "Infrastructure" BB[Browserbase Cloud] SESSION[Session Management] METRICS[Observability] end DEV --> API NL --> API SCHEMA --> API API --> ATOMIC API --> AGENT API --> CACHE ATOMIC --> LLM AGENT --> LLM LLM --> OPENAI LLM --> ANTHROPIC LLM --> GEMINI LLM --> LOCAL ACT --> PW EXTRACT --> A11Y OBSERVE --> A11Y PW -.-> BB BB --> SESSION BB --> METRICS ``` ### Revolutionary accessibility tree processing The migration from raw DOM parsing to Chrome's Accessibility Tree represents Stagehand's most significant architectural innovation. Instead of relying on brittle HTML structures, Stagehand leverages Playwright's capability to access Chrome's Accessibility Tree. This tree provides a semantic representation of web pages, filtered to include only interactive and meaningful elements. This architectural choice dramatically improves both performance and resilience: the accessibility tree remains stable even when visual layouts change, offering a cleaner and more stable view of web pages by filtering out unnecessary noise. This typically reduces the data size by 80-90% compared to raw DOM, directly translating to lower token usage and faster LLM processing. The core AI handlers (`ActHandler`, `ExtractHandler`, `ObserveHandler`) utilize this semantic tree, sending an optimized representation to the LLM for interpretation. This approach provides multiple engineering advantages: element roles and ARIA labels offer semantic meaning that maps naturally to human language instructions, and the tree structure's stability across visual redesigns ensures that automation scripts represent functional intent rather than visual layout. Furthermore, Stagehand injects a helper script (`lib/dom/process.ts`) into the browser context to enable robust Shadow DOM piercing, allowing its custom selector engine to traverse and interact with elements hidden within both open and closed shadow roots. ```mermaid graph LR subgraph "Traditional Approach" DOM1[Raw DOM] PARSE1[DOM Parser] SELECT1[CSS/XPath Selectors] ACTION1[Browser Action] DOM1 --> PARSE1 PARSE1 --> SELECT1 SELECT1 --> ACTION1 end subgraph "Stagehand Approach" DOM2[Raw DOM] A11Y[Accessibility Tree] SEMANTIC[Semantic Analysis] LLM[LLM Processing] ACTION2[Browser Action] DOM2 --> A11Y A11Y --> SEMANTIC SEMANTIC --> LLM LLM --> ACTION2 end style A11Y fill:#f9f,stroke:#333,stroke-width:4px style SEMANTIC fill:#bbf,stroke:#333,stroke-width:2px ``` #### Core accessibility implementation ```typescript // Simplified representation of A11Y tree processing class StagehandPage extends Page { async extractFromA11Y(instruction: string) { // Get accessibility tree snapshot const a11yTree = await this.accessibility.snapshot(); // Filter to interactive elements only const interactiveNodes = filterInteractiveElements(a11yTree); // Convert to semantic representation const semanticTree = { buttons: interactiveNodes.filter(n => n.role === 'button'), inputs: interactiveNodes.filter(n => n.role === 'textbox'), links: interactiveNodes.filter(n => n.role === 'link'), // Include name, description, and state for each element metadata: interactiveNodes.map(n => ({ role: n.role, name: n.name, description: n.description, state: n.pressed || n.checked || n.selected })) }; // Send optimized tree to LLM return await this.llm.process(semanticTree, instruction); } } ``` ### Caching Stagehand's caching system operates through a unified LLM response cache to minimize API costs and improve performance: - **File-based LLM cache**: The `LLMCache` class extends `BaseCache` and stores LLM responses in JSON files on disk. When `enableCaching` is enabled, all LLM provider clients check for cached responses before making API calls. - **Cache integration pattern**: Every LLM client (`OpenAIClient`, `AnthropicClient`, `AISdkClient`, etc.) follows the same caching pattern - checking cache before API calls and storing responses after successful calls. - **Action cache**: There is also an `ActionCache` class that stores browser action steps (in a JSON format), but this operates independently as a separate caching mechanism for Playwright commands and browser actions. ```mermaid stateDiagram-v2 [*] --> Observe: User Instruction Observe --> Preview: Generate Action Preview --> Decision: Developer Reviews Decision --> Cache: Approve Action Decision --> Modify: Adjust Instruction Modify --> Observe: Retry Cache --> Execute: Run Cached Action Execute --> [*]: Complete state Cache { [*] --> LLMCache: Store LLM Response [*] --> ActionCache: Store Browser Action LLMCache --> FileSystem: JSON File Storage ActionCache --> FileSystem: JSON File Storage } ``` #### Caching implementation pattern ```typescript class ActionCache { private memoryCache = new Map(); private sessionCache: SessionStorage; private globalCache: CloudCache; async cacheAction(instruction: string, action: BrowserAction) { const cacheKey = this.generateKey(instruction, action.context); // Multi-level cache write this.memoryCache.set(cacheKey, action); await this.sessionCache.persist(cacheKey, action); // Global cache for high-confidence actions only if (action.confidence > 0.95) { await this.globalCache.share(cacheKey, action); } } async retrieveAction(instruction: string, context: PageContext) { const cacheKey = this.generateKey(instruction, context); // Hierarchical retrieval return this.memoryCache.get(cacheKey) || await this.sessionCache.get(cacheKey) || await this.globalCache.get(cacheKey); } } ``` ### Multi-model LLM provider abstraction Stagehand employs a sophisticated **multi-model LLM routing system** that abstracts away the complexities of various LLM providers. Through extensive empirical testing and a comprehensive `modelToProviderMap`, we discovered that different large language models excel at distinct tasks. For instance, Claude is optimal for high-level reasoning and planning, GPT-4o performs best for executing specific browser actions, and Gemini offers superior cost-performance for observation tasks. The system intelligently routes each operation to the most suitable model, maximizing both accuracy and cost-effectiveness. Stagehand supports a wide array of LLM providers including OpenAI, Anthropic, Google, Cerebras, and Groq, and further extends its compatibility through integration with the `@ai-sdk` ecosystem, allowing for seamless use of models from providers like xAI, Azure, TogetherAI, Mistral, Perplexity, and Ollama. This flexible architecture ensures optimal model selection for diverse automation needs. ```mermaid graph TD REQUEST[Automation Request] --> ANALYZER[Task Analyzer] ANALYZER --> REASONING{High-Level Reasoning?} REASONING -->|Yes| CLAUDE[Claude 3.5] REASONING -->|No| SPECIFIC{Specific Action?} SPECIFIC -->|Yes| GPT4O[GPT-4o Mini] SPECIFIC -->|No| OBSERVE{Observation Task?} OBSERVE -->|Yes| GEMINI[Gemini Pro] OBSERVE -->|No| FALLBACK[Default Model] CLAUDE --> EXECUTE[Execute Task] GPT4O --> EXECUTE GEMINI --> EXECUTE FALLBACK --> EXECUTE ``` #### Model router implementation ```typescript class LLMRouter { private modelBenchmarks = { claude: { reasoning: 0.95, actions: 0.82, observe: 0.78, cost: 3 }, gpt4o: { reasoning: 0.85, actions: 0.94, observe: 0.83, cost: 2 }, gemini: { reasoning: 0.75, actions: 0.79, observe: 0.91, cost: 1 } }; selectModel(task: AutomationTask): ModelSelection { // Analyze task characteristics const taskProfile = this.analyzeTask(task); // Score each model for this specific task const scores = Object.entries(this.modelBenchmarks).map(([model, bench]) => { const performanceScore = bench.reasoning * taskProfile.reasoningWeight + bench.actions * taskProfile.actionWeight + bench.observe * taskProfile.observeWeight; // Cost-adjusted score const costAdjustedScore = performanceScore / Math.log(bench.cost + 1); return { model, score: costAdjustedScore }; }); // Select optimal model return scores.sort((a, b) => b.score - a.score)[0].model; } } ``` ### TypeScript-first schema extraction The schema extraction system leverages Zod's powerful validation capabilities to ensure type-safe data extraction from unstructured web content. This approach transforms web scraping from a fragile string-parsing exercise into a robust, typed data pipeline that catches errors at compile time rather than runtime. ```mermaid sequenceDiagram participant Dev as Developer participant SH as Stagehand participant Schema as Zod Schema participant LLM as LLM participant Page as Web Page Dev->>SH: extract({schema: ProductSchema}) SH->>Page: Get Accessibility Tree Page-->>SH: A11Y Nodes SH->>Schema: Generate Extraction Prompt Schema-->>SH: Typed Prompt with Constraints SH->>LLM: Process with Schema Context LLM-->>SH: Raw Extraction SH->>Schema: Validate & Transform Schema-->>SH: Typed Result SH-->>Dev: Fully Typed Data ``` #### Schema extraction implementation ```typescript // Example of production schema extraction const ProductSchema = z.object({ title: z.string().min(1).max(200), price: z.number().positive().transform(val => Math.round(val * 100) / 100), availability: z.enum(['in-stock', 'out-of-stock', 'pre-order']), images: z.array(z.string().url()).min(1), specifications: z.record(z.string(), z.string()).optional(), reviews: z.object({ average: z.number().min(0).max(5), count: z.number().int().nonnegative() }).optional() }); class SchemaExtractor { async extract(page: Page, schema: ZodSchema, instruction: string): Promise { // Generate JSON schema from Zod const jsonSchema = zodToJsonSchema(schema); // Create extraction prompt with schema constraints const prompt = ` Extract the following information: ${instruction} Required format: ${JSON.stringify(jsonSchema, null, 2)} Extraction rules: - Only include fields defined in the schema - Ensure all required fields are present - Transform data to match type constraints - Use null for optional missing fields `; // Get raw extraction from LLM const rawData = await this.llm.extract(page, prompt); // Validate and transform through Zod const result = schema.safeParse(rawData); if (!result.success) { // Intelligent retry with error context const retryPrompt = this.generateRetryPrompt(result.error, rawData); const retryData = await this.llm.extract(page, retryPrompt); return schema.parse(retryData); // Throw if still invalid } return result.data; } } ``` ### Observe-act caching pattern To address the inherent unpredictability of AI-driven automation, Stagehand implements an **observe-act caching pattern**. This allows developers to preview what the AI intends to do (`observe`) before execution. Once an action is validated and successful, it can be cached for deterministic replay. This pattern ensures reliability through consistent execution, boosts performance by eliminating redundant LLM calls, and optimizes costs by reducing API usage. Cached actions can persist across browser sessions and deployments, building a knowledge base of proven automation patterns. ### Agent orchestration for complex workflows Stagehand introduces an **agent layer** capable of handling complex, multi-step workflows. The `StagehandAgent` class delegates the core intelligence to an underlying `AgentClient` (e.g., `OpenAICUAClient`), which leverages specialized LLM APIs for computer use. These agents operate through an iterative execution loop: 1. **Instruction to action:** The agent receives a high-level instruction (goal). 2. **LLM reasoning:** The `AgentClient` sends the current state (including a screenshot of the browser) and the instruction to the LLM (e.g., OpenAI's Responses API for Computer Use). The LLM then reasons about the next best action. 3. **Action execution:** The LLM returns a structured action (e.g., a click, type, or navigation). The `AgentClient` executes this action in the browser. 4. **Visual feedback loop:** After executing an action, a new screenshot of the browser's state is captured and sent back to the LLM. This visual feedback allows the agent to "observe" the outcome of its action and adapt its subsequent steps. 5. **Self-healing and adaptation:** If an action fails or the page state is unexpected, the `AgentClient` can send error information back to the LLM. The LLM then dynamically adjusts its approach, tries alternative methods, or even reformulates the problem, enabling sophisticated self-healing capabilities without explicit planner or decomposer classes. The planning and decomposition logic are implicitly handled by the LLM itself within this iterative request/response cycle. This iterative process allows agents to maintain context across numerous actions, adapt to unexpected situations, and recover from errors, making them suitable for production environments where websites change frequently and unpredictably. ### Browser session persistence Leveraging Browserbase's cloud infrastructure, Stagehand provides robust **browser session persistence**. This ensures that long-running automation tasks can survive network disconnections, process crashes, and system restarts while maintaining full browser state, including cookies, local storage, and page context. This capability is crucial for enterprise-grade, resilient automation. ```mermaid stateDiagram-v2 [*] --> CreateSession: Initialize Browser CreateSession --> ActiveSession: Session ID Generated ActiveSession --> SaveContext: Periodic Checkpoint SaveContext --> CloudStorage: Persist State CloudStorage --> ActiveSession: Continue Execution ActiveSession --> Disconnect: Network Issue Disconnect --> Reconnect: Retry Connection Reconnect --> RestoreContext: Load from Cloud RestoreContext --> ActiveSession: Resume Execution ActiveSession --> Complete: Task Finished Complete --> [*] ``` #### Session management implementation ```typescript class SessionManager { private browserbase: BrowserbaseClient; private checkpointInterval = 30000; // 30 seconds async createPersistentSession(options: SessionOptions): Promise { // Create cloud-hosted browser session const session = await this.browserbase.sessions.create({ projectId: options.projectId, persistent: true, keepAlive: true, region: options.region || 'auto' }); // Set up automatic checkpointing const checkpointTimer = setInterval(async () => { await this.checkpoint(session); }, this.checkpointInterval); // Configure reconnection logic session.on('disconnect', async () => { clearInterval(checkpointTimer); await this.handleDisconnection(session); }); return { ...session, resume: async () => this.resumeSession(session.id), checkpoint: async () => this.checkpoint(session) }; } private async checkpoint(session: Session) { const state = { cookies: await session.context.cookies(), localStorage: await session.evaluate(() => ({ ...localStorage })), sessionStorage: await session.evaluate(() => ({ ...sessionStorage })), url: session.url(), viewport: session.viewportSize(), // Custom application state customState: await session.evaluate(() => window.__appState) }; await this.browserbase.sessions.saveState(session.id, state); } async resumeSession(sessionId: string): Promise { const session = await this.browserbase.sessions.connect(sessionId); const state = await this.browserbase.sessions.loadState(sessionId); // Restore browser state await session.context.addCookies(state.cookies); await session.goto(state.url); await session.evaluate((state) => { Object.entries(state.localStorage).forEach(([k, v]) => { localStorage.setItem(k, v); }); Object.entries(state.sessionStorage).forEach(([k, v]) => { sessionStorage.setItem(k, v); }); window.__appState = state.customState; }, state); return session; } } ``` ### Advanced performance optimization strategies The framework incorporates several advanced strategies to reduce latency, minimize costs, and improve reliability: - **DOM chunking:** Intelligently segments large pages into processable chunks, preventing token limit errors and preserving context. - **Parallel execution:** Identifies independent operations and executes them concurrently, significantly reducing end-to-end execution time. - **Token minimization:** Optimizes prompts by removing redundant information, compressing descriptions, and using references for repeated elements, leading to substantial cost savings. - **Connection pooling:** Further enhances performance by efficiently managing browser connections. ```mermaid graph LR subgraph "Performance optimizations" OPT1[DOM chunking] OPT2[Parallel execution] OPT3[Token minimization] OPT4[Connection pooling] OPT5[Predictive Caching] end subgraph "Metrics" LATENCY[Latency: -67%] TOKENS[Tokens: -71%] COST[Cost: -63%] RELIABILITY[Reliability: +34%] end OPT1 --> TOKENS OPT2 --> LATENCY OPT3 --> COST OPT4 --> LATENCY OPT5 --> COST style LATENCY fill:#9f9,stroke:#333,stroke-width:2px style RELIABILITY fill:#9f9,stroke:#333,stroke-width:2px ``` #### Performance optimization implementation ```typescript class PerformanceOptimizer { // Intelligent DOM chunking for large pages async chunkDOM(page: Page, maxTokens: number = 4000): Promise { const fullTree = await page.accessibility.snapshot(); const chunks: DOMChunk[] = []; // Smart chunking that preserves context const chunkBoundaries = this.identifySemanticBoundaries(fullTree); for (const boundary of chunkBoundaries) { const chunk = { content: this.extractSubtree(fullTree, boundary), context: this.preserveContext(fullTree, boundary), tokens: this.estimateTokens(boundary) };

// Compress element descriptions const compressed = this.compressDescriptions(deduped); // Use references for repeated elements const referenced = this.createReferences(compressed); // Generate minimal prompt return this.generateMinimalPrompt(instruction, referenced); } } ``` ## Data structures and algorithms Stagehand's architecture is built upon a set of key TypeScript classes and data structures that orchestrate its hybrid intelligence operations: - **`Stagehand` Class (`lib/Stagehand.ts`):** This is the main orchestrator class, responsible for managing the browser lifecycle, initialization (`stagehand.init()`), and providing access to core functionalities like agent creation (`stagehand.agent()`) and cleanup (`stagehand.close()`). - **`StagehandPage` Class (`lib/StagehandPage.ts`):** An enhanced Playwright `Page` object that exposes Stagehand's AI-powered methods (`act()`, `extract()`, `observe()`). It handles the translation of natural language instructions into precise browser actions. - **`StagehandContext` Class (`lib/StagehandContext.ts`):** Manages browser contexts, allowing for the creation of new pages (`newPage()`) and managing multiple pages within a session. - **`LLMProvider` Class (`lib/llm/LLMProvider.ts`):** Acts as a multi-model LLM client factory, abstracting away the specifics of different LLM providers (OpenAI, Anthropic, Google, local models). It's responsible for selecting and interfacing with the appropriate LLM based on task requirements. - **Handler classes (`lib/handlers/`):** - **`ActHandler`:** Implements the logic for natural language action execution (`act()` method). - **`ExtractHandler`:** Manages structured data extraction (`extract()` method), integrating with Zod schemas. - **`ObserveHandler`:** Handles AI-powered element identification and analysis (`observe()` method). - **Accessibility tree snapshot:** A filtered, semantic representation of the web page, used as a key input for LLM processing. It typically contains interactive elements (buttons, inputs, links) and their metadata (role, name, description, state). - **Zod schemas:** Used extensively for defining the structure and validation rules for extracted data. These schemas are transformed into JSON Schema for LLM prompting and then used to `safeParse` and validate the raw LLM output, ensuring type safety and data integrity. - **`ActionCache`:** Internally uses a `Map` for in-memory caching, and interacts with `SessionStorage` and `CloudCache` for persistent and global caching. It stores `CachedAction` objects, which encapsulate the browser action and its context. - **`LLMRouter`:** Employs a `modelBenchmarks` object (a dictionary of models with their performance scores across reasoning, actions, and observation tasks, along with cost metrics) to calculate a cost-adjusted score and select the optimal LLM for a given `AutomationTask`. - **`StagehandAgent`:** Orchestrates complex workflows using a `TaskPlanner` (to create `plan` objects with `tasks`), an `AtomicExecutor` (to execute tasks, potentially in parallel), and `ContextMemory` (to maintain state and context). It manages `executionState` objects, tracking `completed`, `pending`, and `failed` tasks, and their associated context. - **`SessionManager`:** Manages `Session` objects, which represent persistent browser instances. It checkpoints and restores `state` objects containing cookies, local storage, session storage, URL, viewport size, and custom application state. - **`PerformanceOptimizer`:** Works with `DOMChunk` objects (containing content, context, and token estimates) for intelligent page segmentation. It builds `dependencyGraph` and `executionPlan` (via topological sort) for parallel task execution, and processes `Task` and `Result` objects. ## Technical challenges and solutions We have successfully addressed several fundamental challenges that have historically plagued browser automation: - **The brittleness problem:** Traditional tools break when UI changes. Stagehand solves this by combining semantic understanding via the **Accessibility Tree** with AI's ability to interpret intent. This allows scripts to understand their goal rather than relying on rigid selectors, making them resilient to UI modifications. - **The unpredictability challenge:** Pure AI agents lack consistency for production systems. The **hybrid approach** provides granular control: developers can preview AI actions (`observe`), cache successful patterns for deterministic reuse, and seamlessly mix traditional code with AI instructions within the same script. This ensures the predictability required for business-critical automation. - **The performance and cost problem:** Frequent, expensive LLM calls can be prohibitive. Stagehand addresses this critical challenge through a multi-pronged approach to LLM cost management. This includes **intelligent caching** (memory, session, and global caching) to eliminate redundant LLM calls, **session affinity** for connection reuse, and **DOM chunking** strategies that minimize the amount of data sent to LLMs, thereby reducing token usage. Furthermore, the **multi-model routing system** dynamically selects the most cost-effective LLM for each specific task, ensuring that simpler operations utilize cheaper models while reserving premium models for complex reasoning. These comprehensive optimizations have collectively reduced LLM costs by up to 70% compared to naive implementations, while simultaneously improving reliability through cached action replay. While Stagehand excels, we continuously identify areas for improvement. Handling **complex Single Page Applications (SPAs)**, especially those with heavy Shadow DOM usage or intricate state management, remains an ongoing challenge. We are also focused on enhancing the **local development experience** with better tooling for debugging AI decisions and improving **model cost predictability** through more robust estimation and budget enforcement mechanisms. ## Clever tricks and tips discovered along the way Stagehand has yielded several key insights and innovative approaches: - **Accessibility tree as a semantic filter:** This was a game-changer. By processing the accessibility tree instead of the raw DOM, we not only achieved significant performance gains (80-90% data reduction) but also gained a more stable and semantically rich representation of web pages, which is ideal for AI interpretation. - **Optimized multi-model LLM routing:** Recognizing that no single LLM is best for all tasks allowed us to create a dynamic routing system. This "best tool for the job" approach dramatically improves both accuracy and cost-efficiency by leveraging the unique strengths of models like Claude, GPT-4o, and Gemini. - **The `observe` primitive:** This unique feature provides an unprecedented level of control and transparency over AI actions. Developers can "see" what the AI intends to do before it acts, fostering trust and enabling the caching of validated actions for future deterministic execution. - **TypeScript-first with Zod for data extraction:** This combination transforms web scraping from a fragile, error-prone process into a robust, type-safe data pipeline. Compile-time validation catches errors early, and full TypeScript inference throughout the extraction process significantly enhances developer experience. - **Self-healing agent orchestration with visual feedback:** The agents go beyond simple retries. Leveraging specialized LLM APIs for computer use, they operate through an iterative execution loop. After each action, a new screenshot of the browser's state is captured and sent back to the LLM as visual feedback. This allows the agent to "observe" the outcome, analyze failure contexts, dynamically adjust its approach, and even reformulate problems. This resilience is critical for automating complex, real-world workflows that are prone to unexpected changes. - **Persistent browser sessions:** The ability to maintain full browser state across disconnections and restarts ensures that long-running automation tasks are incredibly reliable, a crucial feature for enterprise-level operations. - **Holistic performance optimizations:** Beyond caching, strategies like intelligent DOM chunking, parallel execution with dependency resolution, and meticulous prompt optimization for token minimization have collectively delivered 3-5x speed improvements and 60-70% cost reductions, demonstrating that performance and cost-efficiency can be achieved simultaneously. ## Future improvement considerations ### Architecture improvements **Simplify caching strategy** The current caching implementation is already quite simple with just LLM response caching, but future improvements could include: - Predictive caching based on common automation patterns - Better cache invalidation strategies for dynamic content - Cross-session cache sharing for enterprise deployments **Enhanced error recovery** While Stagehand has self-healing capabilities, future improvements could include: - More granular error classification with specific recovery strategies - Better context preservation during error recovery - Automated fallback to simpler automation methods when AI fails ### Performance optimizations **Reduce token usage further** The framework already optimizes token usage through accessibility tree processing, but could improve with: - Better DOM chunking algorithms for complex SPAs - More aggressive prompt compression techniques - Dynamic model selection based on page complexity **Faster action execution** Recent changes show focus on performance improvements, with future enhancements including: - Parallel execution of independent actions - Better prediction of action success before execution - Reduced screenshot frequency for agent workflows ### Developer experience enhancements **Better debugging tools** The framework has improved logging, but could add: - Visual debugging interface for AI decision-making - Better action replay and modification tools - More detailed metrics on automation reliability **Improved local development** Recent work on local browser options could be extended with: - Better hot-reloading for automation scripts - Improved browser profile management - Enhanced stealth mode for local testing ### AI model integration **Better model routing** While Stagehand supports multiple providers, future improvements could include: - Dynamic model switching based on real-time performance - Cost-aware model selection with budget constraints - Better handling of model-specific capabilities **Enhanced agent capabilities** The agent system introduced could be improved with: - Better long-term memory across sessions - More sophisticated planning algorithms - Integration with external knowledge bases ### Production readiness **Better Monitoring and Observability** Current metrics tracking could be enhanced with: - Real-time automation health dashboards - Predictive failure detection - Better integration with existing monitoring tools **Enhanced security** Future improvements could include: - Better credential management for automation scripts - Enhanced browser fingerprint protection - Audit logging for compliance requirements ### Framework integration **Broader ecosystem support** The framework already integrates with LangChain and CrewAI, but could expand to: - More workflow orchestration platforms - Better CI/CD pipeline integration - Enhanced testing framework support ## Conclusion Stagehand represents a pivotal advancement in browser automation, successfully merging deterministic reliability with AI-driven adaptability. Its rapid adoption and the profound technical innovations—from the accessibility tree architecture to the observe-act pattern and multi-model routing—underscore its capacity to solve long-standing challenges in the field. Stagehand's production readiness, robust TypeScript implementation, and enterprise-grade features position it as the definitive solution for organizations seeking to harness AI in their automation workflows. We believe Stagehand is not merely a tool, but a foundational platform for the next generation of human-computer interaction through the browser, offering an optimal balance of power, reliability, and cost-effectiveness for engineering teams.

Context7 breakdown

## Overview Context7 is an intelligent documentation indexing and retrieval system that fundamentally changes how technical documentation becomes usable for AI systems. Unlike traditional approaches that dump raw markdown into vector databases, Context7 transforms documentation through a sophisticated 5-stage pipeline - parsing, enriching, vectorizing, reranking, and caching - to produce AI-optimized snippets that LLMs can actually use to generate working code. ### The problem is real Traditional documentation retrieval systems fail spectacularly for AI code generation. When developers query "Next.js app router setup", they get either outdated examples from training data, raw documentation dumps that waste precious context tokens, or worse - AI hallucinations. LLMs confidently generate APIs that never existed, mix syntax from different versions, or create plausible-looking but completely fictional function names. The core issue: documentation isn't optimized for AI consumption, and without authoritative context, LLMs fill gaps with convincing but broken code. Raw markdown mixed with project metadata, unranked code snippets, and version mismatches create noise that confuses LLMs and generates broken code. **Context7's core innovation**: A 5-stage documentation processing pipeline that transforms raw library docs into AI-optimized, ranked snippets. The system parses 33k+ libraries, enriches content with LLM-generated metadata, vectorizes using multiple embedding models, applies a 5-metric ranking system, and caches results for instant retrieval. The MCP integration is just the delivery mechanism - the real magic happens in the indexing and ranking algorithms. ### Key technical advances - **Multi-stage documentation processing**: 5-pipeline transformation from raw docs to AI-ready snippets - **5-metric quality ranking**: Question relevance, LLM evaluation, formatting, metadata filtering, initialization guidance - **Intelligent snippet structuring**: Consistent TITLE/DESCRIPTION/CODE format with 40-dash delimiters - **Real-time cache invalidation**: Version-aware caching that automatically updates when libraries change ### Architecture components **Documentation Processing Pipeline**: - Parse stage: Multi-format extraction (Markdown, MDX, rST, Jupyter) - Enrich stage: LLM-powered metadata generation - Vectorize stage: Multi-model embedding generation - Rerank stage: 5-metric evaluation and scoring - Cache stage: Redis-powered optimization with smart invalidation **Quality Evaluation System**: - Question relevance engine: 15 developer questions tested per snippet - LLM quality assessment: Gemini AI technical evaluation - Rule-based validation: Formatting and completeness checks - Noise detection: Citations, licenses, directory structure filtering - Setup guidance: Import/install instruction prioritization **Search and Retrieval Infrastructure**: - Library resolution: Fuzzy matching with LLM disambiguation - Token-aware filtering: Budget-constrained result optimization - Version tracking: Git-based change detection and cache invalidation ### Real-world impact **Before Context7**: "Create a Next.js app with app router" → Generic response based on Next.js 12 training data → Broken code → Manual documentation lookup → Trial and error → 30+ minutes wasted **With Context7**: "Create a Next.js app with app router. use context7" → Real Next.js 15 docs injected → 5-metric ranking applied → Best snippets surfaced first → Working code with current APIs → 0 minutes debugging **See it in action**: Watch how Context7's intelligent ranking delivers better code examples compared to traditional documentation injection, demonstrated through building an MCP Python agent for Airbnb using the MCPUs framework. ## How it works ### Architecture overview The magic happens through a sophisticated pipeline that intercepts LLM prompts, identifies library references, fetches current documentation, and seamlessly injects it into the conversation context. The entire process takes milliseconds but saves hours of debugging. ```mermaid graph TB subgraph "MCP Clients" Cursor["Cursor IDE"] VSCode["VS Code"] Claude["Claude Desktop"] Windsurf["Windsurf"] Other["20+ Other Clients"] end subgraph "Context7 MCP Server" CLI["CLI Entry Point

Please try again later.` ); return { results: [], error: `Rate limited due to too many requests. Please try again later.`, } as SearchResponse; } // Generic error handling console.error(`Failed to search libraries. Error code: ${errorCode}`); return { results: [], error: `Failed to search libraries. Error code: ${errorCode}`, } as SearchResponse; } return await response.json(); } catch (error) { console.error("Error searching libraries:", error); return { results: [], error: `Error searching libraries: ${error}`, } as SearchResponse; } } ``` Why this works: The LLM evaluates results based on: - Name similarity (exact matches prioritized) - Description relevance to query intent - Documentation coverage (`totalSnippets` as quality signal) - Trust score (7-10 considered authoritative) - Document state (prefer "finalized" over "initial") ### Token-aware documentation filtering The clever bit is Context7 enforces a minimum token guarantee while keeping the client simple: ```typescript // Actual implementation from Context7 MCP const DEFAULT_MINIMUM_TOKENS = 10000; server.tool( "get-library-docs", "Fetches up-to-date documentation for a library", { context7CompatibleLibraryID: z .string() .describe("Exact Context7-compatible library ID"), topic: z.string().optional().describe("Topic to focus documentation on"), tokens: z .preprocess( (val) => (typeof val === "string" ? Number(val) : val), z.number() ) // The trick: Never go below minimum for quality .transform((val) => val < DEFAULT_MINIMUM_TOKENS ? DEFAULT_MINIMUM_TOKENS : val ) .optional() .describe( `Maximum tokens of documentation (min: ${DEFAULT_MINIMUM_TOKENS})` ), }, async ({ context7CompatibleLibraryID, tokens = DEFAULT_MINIMUM_TOKENS, topic = "", }) => { // Fetch with token budget const fetchDocsResponse = await fetchLibraryDocumentation( context7CompatibleLibraryID, { tokens, topic }, clientIp ); if (!fetchDocsResponse) { return { content: [ { type: "text", text: "Documentation not found or not finalized for this library.", }, ], }; } // Return raw documentation - ranking happens server-side return { content: [ { type: "text", text: fetchDocsResponse, }, ], }; } ); ``` The magic happens on Context7's servers - proprietary ranking algorithms select the most valuable documentation chunks within the token budget. This keeps the MCP server lightweight while allowing continuous algorithm improvements. ### Data indexing and processing pipeline Behind Context7's real-time documentation injection lies a sophisticated 5-stage pipeline that transforms raw documentation into AI-optimized content. This isn't just scraping docs - it's intelligent processing that makes documentation actually useful for LLMs. ```mermaid flowchart LR A[Raw Documentation] --> B[Stage 1: Parse
Extract code snippets] B --> C[Stage 2: Enrich
Add LLM metadata] C --> D[Stage 3: Vectorize
Generate embeddings] D --> E[Stage 4: Rerank

Redis optimization] F --> G[AI-Ready Snippets] classDef stage fill:#e8f5e9,stroke:#2e7d32,stroke-width:2px class B,C,D,E,F stage ``` #### Stage 1: Parse - Documentation extraction Context7 doesn't discriminate - it parses everything: Markdown, MDX, plain text, reStructuredText, even Jupyter notebooks. The clever bit: projects can control parsing behavior with a `context7.json` config: ```json { "description": "Brief description of what your library does", "folders": ["docs", "guides"], "excludeFolders": ["src", "build", "node_modules"], "excludeFiles": ["CHANGELOG.md", "LICENSE"], "rules": ["Always use TypeScript for better type safety"], "previousVersions": [{ "tag": "v2.0.0", "title": "Version 2.0" }] } ``` Why this works: Instead of blindly indexing everything, Context7 respects project structure. Documentation stays documentation, source code doesn't pollute the index. #### Stage 2: Enrich - LLM-powered metadata generation Raw code snippets aren't enough. Context7 uses LLMs to generate contextual metadata - not just what the code does, but when and why to use it. This enrichment phase transforms dead examples into living documentation. #### Stage 3: Vectorize - Embedding generation Context7 leverages Upstash Vector with multiple embedding model options: - **WhereIsAI/UAE-Large-V1**: 1024 dimensions for maximum precision - **BAAI/bge-m3**: 8192 sequence length for handling large code blocks - **sentence-transformers/all-MiniLM-L6-v2**: 384 dimensions for speed The trick: Different models for different use cases. Small snippets get fast models, complex examples get high-precision embeddings. #### Stage 4: Rerank - Proprietary relevance scoring This is where the 5-metric evaluation system kicks in. Context7's proprietary algorithm doesn't just rely on vector similarity - it considers question relevance, code quality, formatting, metadata, and initialization guidance to surface the best snippets first. #### Stage 5: Cache - Redis-powered optimization The final optimization: Redis caching at multiple levels. Popular snippets, common queries, frequently accessed libraries - all cached for instant retrieval. No redundant processing, just immediate responses. ### Documentation quality ranking system The problem with documentation retrieval isn't finding snippets - it's finding the RIGHT snippets. Context7 fetches hundreds of code examples per library, but without intelligent ranking, developers waste time scrolling through irrelevant examples. The solution: a 5-metric evaluation system that creates a "quality leaderboard" for code snippets. ```mermaid flowchart TD A[Library Snippets from Context7 API] --> B[5-Metric Evaluation Pipeline] B --> C[Question Relevance

Unlike generic quality metrics, this tests against real developer questions: ```typescript // From src/services/search.ts - Actual question evaluation implementation async evaluateQuestions(questions: string, contexts: string[][]): Promise { const prompt = questionEvaluationPromptHandler(questions, contexts, this.prompts?.questionEvaluation); const config: object = { responseMimeType: "application/json", responseSchema: { type: Type.OBJECT, properties: { questionAverageScore: { type: Type.NUMBER }, questionExplanation: { type: Type.STRING }, }, required: ["questionAverageScore", "questionExplanation"], }, ...this.llmConfig } const response = await runLLM(prompt, config, this.client); const jsonResponse = JSON.parse(response); return { questionAverageScore: jsonResponse.questionAverageScore, questionExplanation: jsonResponse.questionExplanation }; } ``` Why this works: The system evaluates each snippet against 15 actual developer questions, scoring how well it answers each one. A snippet showing "npm install react" scores 100 for "How to install React?" but 0 for "How to optimize React performance?". This laser focus on actual developer needs is why the metric gets 80% weight. #### Metric 2: LLM quality assessment (5% weight) Gemini AI evaluates the technical substance of each snippet: ```typescript // From src/services/llmEval.ts - Actual LLM evaluation implementation async llmEvaluate(snippets: string): Promise { const snippetDelimiter = "\n" + "-".repeat(40) + "\n"; const prompt = llmEvaluationPromptHandler(snippets, snippetDelimiter, this.prompts?.llmEvaluation); const config: object = { responseMimeType: 'application/json', responseSchema: { type: 'object', properties: { llmAverageScore: { type: Type.NUMBER }, llmExplanation: { type: Type.STRING }, }, required: ["llmAverageScore", "llmExplanation"], }, ...this.llmConfig } const response = await runLLM(prompt, config, this.client); const jsonResponse = JSON.parse(response); return { llmAverageScore: jsonResponse.llmAverageScore, llmExplanation: jsonResponse.llmExplanation }; } ``` The trick: LLM evaluation catches subtle issues like deprecated APIs or anti-patterns that rule-based checks miss. The AI evaluates relevancy, clarity, and correctness, but at 5% weight, it refines rather than dominates the ranking. #### Metric 3: Formatting validation (5% weight) Rule-based checks ensure structural completeness: ````typescript // From src/lib/textEval.ts - Actual formatting evaluation formatting(): TextEvaluatorOutput { const snippetsList = this.splitSnippets(); let improperFormatting = 0; for (const snippet of snippetsList) { const missingInfo = metrics.snippetIncomplete(snippet); const shortCode = metrics.codeSnippetLength(snippet); const descriptionForLang = metrics.languageDesc(snippet); const containsList = metrics.containsList(snippet); if ([missingInfo, shortCode, descriptionForLang, containsList].some(test => test)) { improperFormatting++; } } return { averageScore: ((snippetsList.length - improperFormatting) / snippetsList.length) * 100 }; } // From src/lib/textMetrics.ts - Formatting validation rules export function snippetIncomplete(snippet: string): boolean { const components = ["TITLE:", "DESCRIPTION:", "LANGUAGE:", "SOURCE:", "CODE:"]; return !components.every((c) => snippet.includes(c)); } export function codeSnippetLength(snippet: string): boolean { const codes = accessCategory(snippet, "CODE") as string[]; return codes.some(code => { const codeSnippets = code.split("CODE:") const codeBlock = codeSnippets[codeSnippets.length - 1].replace(/```/g, "") const cleanedCode = codeBlock.trim().replace(/\r?\n/g, " "); return cleanedCode.split(" ").filter(token => token.trim() !== "").length < 5; }) } ```` The formatting checks penalize snippets with missing sections, code blocks shorter than 5 words, or improper structure - ensuring only complete, usable examples rank highly. #### Metric 4: Metadata filtering (2.5% weight) Removes project-specific noise that doesn't help developers: ```typescript // From src/lib/textEval.ts - Actual metadata evaluation metadata(): TextEvaluatorOutput { const snippetsList = this.splitSnippets(); let projectMetadata = 0; for (const snippet of snippetsList) { const citations = metrics.citations(snippet); const licenseInfo = metrics.licenseInfo(snippet); const directoryStructure = metrics.directoryStructure(snippet); if ([citations, licenseInfo, directoryStructure].some(test => test)) { projectMetadata++; } } return { averageScore: ((snippetsList.length - projectMetadata) / snippetsList.length) * 100 }; } // From src/lib/textMetrics.ts - Metadata detection patterns export function citations(snippet: string): boolean { const citationFormats = ["bibtex", "biblatex", "ris", "mods", "marc", "csl json"] const langs = accessCategory(snippet, "LANGUAGE") as string[]; return langs.some(lang => { const langSnippet = lang.split("CODE:")[0]; const cleanLang = langSnippet.trim().replace(/\r?\n/g, "").toLowerCase(); return citationFormats.some(format => cleanLang.includes(format)) }) } export function licenseInfo(snippet: string): boolean { const source = (accessCategory(snippet, "SOURCE") as string).toLowerCase(); return source.includes('license') } ``` The metadata filter identifies and penalizes snippets containing citations, license information, or directory structures - noise that clutters documentation without helping developers write code. #### Metric 5: Initialization guidance (2.5% weight) Prioritizes snippets that help developers get started: ````typescript // From src/lib/textEval.ts - Actual initialization evaluation initialization(): TextEvaluatorOutput { const snippetsList = this.splitSnippets(); let initializationCheck = 0; for (const snippet of snippetsList) { const imports = metrics.imports(snippet); const installs = metrics.installs(snippet); if ([imports, installs].some(test => test)) { initializationCheck++; } } return { averageScore: ((snippetsList.length - initializationCheck) / snippetsList.length) * 100 }; } // From src/lib/textMetrics.ts - Initialization detection logic export function imports(snippet: string): boolean { const importKeywords = ["import", "importing"] const title = (accessCategory(snippet, "TITLE") as string).toLowerCase(); const codes = accessCategory(snippet, "CODE") as string[]; return importKeywords.some((t) => title.includes(t)) && codes.some(code => { const codeSnippet = code.split("CODE:") const cleanedCode = codeSnippet[codeSnippet.length - 1].trim().replace(/```/g, ""); const singleLine = cleanedCode.split(/\r?\n/).filter(line => line.trim() !== "").length == 1; const noPath = !cleanedCode.includes("/"); return singleLine && noPath; }) } export function installs(snippet: string): boolean { const installKeywords = ["install", "initialize", "initializing", "installation"]; const title = (accessCategory(snippet, "TITLE") as string).toLowerCase(); const codes = accessCategory(snippet, "CODE") as string[]; return installKeywords.some((t) => title.includes(t)) && codes.some(code => { const codeSnippet = code.split("CODE:") const cleanCode = codeSnippet[codeSnippet.length - 1].trim().replace(/```/g, ""); const singleLine = cleanCode.split(/\r?\n/).filter(line => line.trim() !== "").length === 1; return singleLine; }) } ```` The initialization check identifies snippets with import statements or installation commands - prioritizing examples that show developers how to set up and start using the library. #### The scoring algorithm All metrics combine into a single quality score: ```typescript // From src/lib/utils.ts - Actual weighted average calculation export function calculateAverageScore( scores: Metrics, weights?: Record ): number { const defaultWeights = { question: 0.8, llm: 0.05, formatting: 0.05, metadata: 0.025, initialization: 0.025, }; const finalWeights = weights || defaultWeights; return ( scores.question * finalWeights.question + scores.llm * finalWeights.llm + scores.formatting * finalWeights.formatting + scores.metadata * finalWeights.metadata + scores.initialization * finalWeights.initialization ); } ``` The weighted calculation ensures question relevance dominates (80%), while other metrics act as quality filters. This creates a ranking where the most helpful snippets - those that directly answer developer questions with clean, complete code - rise to the top. #### Library comparison mode The clever bit: Context7 can compare snippet quality across different libraries for the same product: ```typescript // Library comparison implementation class LibraryComparator { // Same product check using fuzzy matching isSameProduct(lib1: string, lib2: string): boolean { return fuzzyMatch(lib1, lib2) > 0.8; // 80% similarity threshold } compareLibraries(library1: Library, library2: Library): ComparisonResult { // Verify comparing apples to apples if (!this.isSameProduct(library1.name, library2.name)) { throw new Error("Libraries are for different products"); } // Parallel evaluation using identical metrics const scores1 = this.evaluateLibrary(library1); const scores2 = this.evaluateLibrary(library2); return { library1: { name: library1.name, averageScore: scores1.average, strengths: this.identifyStrengths(scores1), weaknesses: this.identifyWeaknesses(scores1), }, library2: { name: library2.name, averageScore: scores2.average, strengths: this.identifyStrengths(scores2), weaknesses: this.identifyWeaknesses(scores2), }, recommendation: scores1.average > scores2.average ? library1 : library2, }; } } ``` #### Real-world ranking example Consider a query for "React hooks useState": ```typescript // Snippet A: Direct useState implementation { TITLE: "Using useState Hook", DESCRIPTION: "Manage component state with useState", CODE: ` import { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return ; } `, // Scoring breakdown questionRelevance: 95, // Directly answers useState question llmQuality: 85, // Clean, modern React code formatting: 100, // All sections present metadata: 100, // No project-specific noise initialization: 90, // Has import, missing install command finalScore: 95 * 0.8 + 85 * 0.05 + 100 * 0.05 + 100 * 0.025 + 90 * 0.025 = 76 + 4.25 + 5 + 2.5 + 2.25 = 90.0 } // Snippet B: Generic React tutorial { TITLE: "React Basics", DESCRIPTION: "Introduction to React components", CODE: ` class Welcome extends React.Component { render() { return

Hello, {this.props.name}

; } } `, // Scoring breakdown questionRelevance: 20, // Tangentially related to hooks llmQuality: 70, // Outdated class component formatting: 100, // Structure is fine metadata: 100, // Clean code initialization: 60, // No imports shown finalScore: 20 * 0.8 + 70 * 0.05 + 100 * 0.05 + 100 * 0.025 + 60 * 0.025 = 16 + 3.5 + 5 + 2.5 + 1.5 = 28.5 } // Result: Snippet A (90.0) ranks 3× higher than Snippet B (28.5) // Developer gets the useState example first, not generic React info ``` #### Why this ranking system works **Question-first approach**: The 80% weight on question relevance means developers get exactly what they're looking for, not just "high-quality" documentation in general. **Quality over quantity**: A library with 10 excellent snippets ranks higher than one with 100 mediocre snippets. **Consistent standards**: Every library gets evaluated by the same metrics, enabling fair comparisons. **Developer-centric focus**: The metrics prioritize what actually helps developers ship code - clear examples, proper setup instructions, and relevant answers. The result: Instead of scrolling through 100+ random snippets, developers see the best examples first. The top 3 snippets typically contain everything needed to solve their problem. No more documentation diving, just immediate answers. ## Technical challenges and solutions ### Challenge 1: Keeping 33k+ libraries updated vs static snapshots **The problem**: Documentation changes constantly. Libraries release new versions, APIs get deprecated, examples become outdated. Traditional documentation systems take snapshots and serve stale data for months. By the time you notice the documentation is wrong, you've already wasted hours debugging. **Context7's solution**: Scheduled sync cycles with intelligent change detection and manual override capabilities. The system operates on three levels: **Automatic sync cycle (10-15 days)**: Context7 automatically crawls all 33k+ libraries on a rolling schedule. Each library gets checked every 10-15 days for updates, ensuring the index stays current without overwhelming source servers. **Manual trigger via Context7 UI**: Users can manually trigger documentation updates for specific libraries through the Context7 interface. This is crucial when developers know a library just released a major update and need the latest docs immediately. **Change detection system**: Before reprocessing, Context7 checks if the library actually has new changes. The system compares: - Git commit hashes for repository-based documentation - Package version numbers from registries (NPM, PyPI, Maven) ![](./assets/context7-refresh-library.png) ### Challenge 2: Context window limitations **The problem**: Modern LLMs have context windows ranging from 8K to 200K tokens. Naive documentation injection could easily consume the entire context, leaving no room for conversation history or causing the LLM to "forget" important instructions. **Context7's solution**: Server-side token management with a default guarantee of 10,000 tokens. The MCP client sends a token limit, Context7's API applies proprietary ranking to return the most relevant documentation within that budget. Code examples rank higher than prose, API signatures higher than descriptions. The result: maximum value per token. ![](./assets/context7-token-limit.gif) ### Challenge 3: Library name ambiguity **The problem**: Users type "React", "react.js", "ReactJS", or "Facebook React" - all referring to the same library. Simple string matching fails, fuzzy matching returns wrong libraries entirely. **Context7's solution**: The `resolve-library-id` tool returns multiple search results with metadata (trust scores, snippet counts, descriptions) and lets the LLM select the most appropriate match. This hybrid approach combines algorithmic search with LLM-powered disambiguation. No complex string matching in the MCP client, just smart delegation. ### Challenge 4: Multi-client compatibility **The problem**: Different MCP clients (Cursor, VS Code, Claude Desktop) have different configuration formats, transport preferences, and connection methods. A one-size-fits-all approach doesn't work. **Context7's solution**: Multi-transport support with auto-detection. The CLI accepts `--transport` flags for stdio (default), HTTP, and SSE. The HTTP server creates different endpoints (`/mcp`, `/sse`, `/messages`) to handle various client patterns. This architecture enables the same server to work across 20+ different MCP clients without modification. ## What we would do differently ### Current limitations and future improvements **Documentation versioning**: Currently, Context7 serves the latest documentation by default. The better approach: ```typescript // Proposed improvement: Version-aware documentation interface VersionedDocRequest { libraryId: string; version?: string; // "15.0.0" or "latest" or "^14.0.0" preferStable?: boolean; // Avoid RC/beta versions } // This would enable: // "Create Next.js 14 app" -> Specifically Next.js 14 docs // "Create Next.js app" -> Latest stable version ``` **Intelligent caching strategy**: The current approach fetches documentation on every request. An improved design would: - Cache documentation locally with smart invalidation - Pre-fetch commonly used libraries during idle time - Use ETags for efficient cache validation - Implement differential updates for documentation changes **Private package support**: Many organizations need documentation for internal packages: ```typescript // Proposed: Private registry support interface PrivateRegistry { authenticate(credentials: Credentials): Promise; indexPrivatePackages(registry: string): Promise; servePrivateDocs(packageId: string, token: Token): Promise; } ``` ### Architectural enhancements **Event-driven architecture**: The current request-response model could benefit from event streaming: ```typescript // Better: Event-driven documentation updates class DocumentationEventStream { async *streamUpdates(libraryId: string) { yield { type: "metadata", data: await this.fetchMetadata(libraryId) }; yield { type: "quickstart", data: await this.fetchQuickStart(libraryId) }; yield { type: "api", data: await this.fetchAPIReference(libraryId) }; yield { type: "examples", data: await this.fetchExamples(libraryId) }; } } ``` ### The bottom line Context7 MCP elegantly solves a real problem every developer faces: LLMs generating outdated or broken code. Its architecture is clean, the implementation is thoughtful, and the results are immediately valuable. While there's room for improvement in versioning, caching, and private package support, the current implementation already saves developers hours of debugging time per week. The true innovation isn't just the technology - it's recognizing that the gap between LLM training and real-world documentation is a solvable problem. By bridging this gap with MCP, Context7 transforms AI coding assistants from frustrating approximators into reliable partners. No more broken imports, no more hallucinated APIs, just working code on the first try.

E2b breakdown

E2B is a cloud-based code execution platform designed for AI applications. By leveraging [Firecracker microVMs](https://firecracker-microvm.github.io/) instead of traditional [containers](https://en.wikipedia.org/wiki/OS-level_virtualization), E2B provides fast startup times and hardware-level isolation for untrusted AI-generated code. This technical breakdown analyzes E2B's architecture and the key components that power its performance. ![E2B](./assets/e2b-illustration-01.png) ## Introduction: The AI code execution challenge ### The problem space AI-powered development tools require secure, fast code execution platforms. Unlike traditional development workflows, AI agents require: - **Rapid iteration cycles** with sub-second response times - **Untrusted code execution** with complete isolation - **Persistent development environments** that maintain state - **[Multi-tenant](https://en.wikipedia.org/wiki/Multitenancy) security** for enterprise deployment ### What is E2b? E2B is an open-source, secure cloud runtime designed for AI applications and agents[¹](https://e2b.dev/docs). The platform provides secure, isolated [sandboxes](https/enwikipedia.org/wiki/sandbox_computer_security)>) in the cloud where AI agents can execute code, access browsers, and use full operating system capabilities. E2B offers JavaScript/TypeScript and Python SDKs for creating and managing sandboxes, connecting LLMs, and executing code across multiple programming languages[¹](https://e2b.dev/docs). ```mermaid graph TB subgraph "E2B Platform Overview" subgraph "AI Development Stack" Dev[AI Developers] --> SDK[E2B SDK] Agent[AI Agents] --> SDK LLM[Language Models] --> SDK end SDK --> API[E2B API Gateway] API --> Orchestrator[Sandbox Orchestrator] subgraph "Compute Infrastructure" Orchestrator --> Pool[Pre-warmed VM Pool] Pool --> VM1[Firecracker VM 1

The boot times shown reflect Firecracker's performance characteristics[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf): ```mermaid sequenceDiagram participant Client as AI Agent/Developer participant API as E2B API participant SessionMgr as Session Manager participant VMPool as VM Pool participant Firecracker as Firecracker VM participant Storage as Persistent Storage Client->>API: Create Sandbox Request API->>SessionMgr: Allocate Resources alt VM Available in Pool SessionMgr->>VMPool: Get Pre-warmed VM VMPool->>Firecracker: Assign VM (Fast) else No VM Available SessionMgr->>VMPool: Create New VM VMPool->>Firecracker: Boot VM (~125-180ms) end Firecracker-->>SessionMgr: VM Ready SessionMgr->>Storage: Load User State Storage-->>Firecracker: Mount Persistent Volume SessionMgr-->>API: Sandbox ID + Connection Details API-->>Client: Sandbox Ready Note over Client,Storage: Active Development Session Client->>API: Execute Code API->>Firecracker: Run Code in VM Firecracker-->>API: Execution Results API-->>Client: Output + Logs Client->>API: Pause Session API->>SessionMgr: Suspend VM SessionMgr->>Storage: Save State Snapshot SessionMgr->>Firecracker: Pause VM Firecracker-->>SessionMgr: VM Suspended Note over Client,Storage: Session Paused (State Preserved) Client->>API: Resume Session API->>SessionMgr: Resume VM SessionMgr->>Storage: Load State Snapshot Storage-->>Firecracker: Restore VM State Firecracker-->>SessionMgr: VM Active SessionMgr-->>API: Session Resumed ``` --- ## What are Firecracker microVMs and why E2B chose them? ### What is a MicroVM? A **[microVM](https://en.wikipedia.org/wiki/Hypervisor#Classification)** (micro virtual machine) is a lightweight virtual machine designed to provide the security and isolation of traditional VMs while maintaining the resource efficiency and rapid startup times of containers[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf). MicroVMs achieve this through a minimalist approach that includes only essential components needed to run applications, eliminating unnecessary OS services and drivers. Unlike traditional VMs, which typically require ~131 MB of memory overhead and boot in seconds, microVMs are optimized for minimal resource usage with only **3-5 MB of memory overhead per instance** and can boot in **≤125 ms (pre-configured) to ~160-180 ms end-to-end**[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf). MicroVMs leverage [KVM](https://en.wikipedia.org/wiki/Kernel-based_Virtual_Machine)-based hardware virtualization to provide hardware-enforced isolation, preventing malicious code from compromising the host system while maintaining the speed and resource efficiency of containers. ### E2B's Firecracker implementation E2B uses **[Firecracker microVMs](https://firecracker-microvm.github.io/)** instead of traditional containers. Firecracker is AWS's purpose-built Virtual Machine Monitor (VMM) written in Rust with approximately **50,000 lines of code compared to QEMU's 1.4 million lines**[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf). Firecracker introduces MicroVMs as a minimalist virtual machine abstraction that combines the security isolation of traditional VMs with the speed and resource efficiency of containers[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf). Key design principles include: - **RESTful API control**: Each MicroVM is configured and controlled via a RESTful API over a UNIX socket, enabling asynchronous setup and fast "start" calls[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Minimal device emulation**: Scoped to essentials—virtio block and network, serial console, and minimal keyboard controller—trading flexibility for dramatically reduced Trusted Computing Base[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Built-in rate limiting**: Token-bucket rate limiters on disk and network I/O enforce bandwidth and IOPS caps per MicroVM, ensuring noisy-neighbor containment[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) #### Architecture and Thread Model ![Firecracker architecture](./assets/e2b-illustration-02.png) Each Firecracker process encapsulates one microVM and runs three types of threads[³](): - **API thread**: Handles Firecracker's REST API server and control plane - **VMM thread**: Manages the machine model and device emulation - **vCPU threads**: Execute guest code via KVM (one thread per virtual CPU) #### Security and Isolation Firecracker implements multi-layered security[³](): - **Hardware-level isolation** with KVM-based virtualization and separate kernels per sandbox[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Jailer process**: In production, runs Firecracker in a secure sandbox with dropped privileges, cgroups, and namespaces[³]() - **Thread-specific seccomp filters**: Limit system calls per thread type for enhanced security[³]() - **Minimal attack surface** through limited device emulation (VirtIO block/network, serial console)[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) #### Performance and Resource Management - **Memory overhead**: ~3-5 MB per MicroVM, regardless of guest memory size (versus ~131 MB for QEMU)[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Boot latency**: Cold-start to guest init in ≤125 ms (pre-configured) and ~160-180 ms end-to-end (including API calls), roughly 2× faster than QEMU[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Creation throughput**: Up to **150 MicroVMs per second per host** without contention[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Rate limiting**: Built-in token bucket algorithm for I/O operations to ensure fair resource usage[³]() - **Production scale**: Supports millions of simultaneous workloads and processes trillions of serverless invocations per month in AWS Lambda and Fargate[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Persistent state management** across code executions with up to 24-hour session duration[¹](https://e2b.dev/docs) #### Serverless Specialization and Production Readiness Firecracker's design reflects specialization for serverless workloads, enabling massive simplification[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf): - **Focused scope**: Drops legacy device support, VM migration, BIOS, and PCI emulation to focus on the 80% of use-cases that power functions and containers[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Memory safety**: Rust's memory safety combined with minimal VMM features reduces attack surface compared to monolithic hypervisors[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Economic efficiency**: Fast startup and low overhead enable high levels of oversubscription and soft resource allocation, delivering multi-tenant serverless benefits without compromising isolation[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) - **Production validation**: Seamless AWS Lambda migration from containers to Firecracker showed no customer-visible regressions, demonstrating production readiness[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf) ### Technical comparison The following comparison is based on the official Firecracker research[²](https://www.usenix.org/system/files/nsdi20-paper-agache.pdf): | Dimension | Linux Containers | QEMU/KVM Virtualization | Firecracker MicroVMs | | --------------------- | ------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------- | ------------------------------------------------------------------------------------ | | **Security** | Depends on kernel syscalls and namespaces; tradeoffs between compatibility and syscall filtering | Full guest kernel, hardware-enforced isolation, large TCB (QEMU+KVM) | Hardware-enforced isolation via KVM, minimal Rust VMM (≈50 KLOC), seccomp-bpf jailer | | **Resource Overhead** | Negligible per container; shared kernel footprint | ~131 MB per VM; seconds-scale boot | ~3–5 MB per MicroVM; < 150 ms boot | | **Boot Time** | Milliseconds (container start) | Seconds (VM) | 125–180 ms | | **Feature Scope** | Full Linux API surface | Broad device and BIOS emulation | Minimal device set (virtio block, net, serial) | | **Multi-Tenancy** | Soft isolation, noisy-neighbor risk | Strong isolation, high overhead | Strong isolation, low overhead | ### Why E2B chose Firecracker E2B's architectural decision to adopt Firecracker microVMs was driven by specific technical requirements for AI code execution platforms: #### Security and isolation requirements E2B requires strong isolation for executing untrusted AI-generated code. Firecracker provides **hardware-level isolation via KVM-based virtualization**, ensuring each sandbox operates with its own kernel and preventing cross-tenant attacks. Unlike container-based solutions that share the host kernel, Firecracker's **minimalist design reduces the attack surface** by excluding unnecessary devices and guest functionality. #### Performance requirements AI development workflows require **rapid environment provisioning** to maintain developer productivity. Firecracker's **≤125 millisecond boot times** enable near-instantaneous sandbox creation, while the **<5 MiB memory overhead per microVM** allows for high-density deployments essential for multi-tenant platforms. #### Resource efficiency E2B's cloud infrastructure requires efficient resource utilization for cost-effective scaling. Firecracker's **built-in rate limiters for network and storage resources** enable optimized sharing across thousands of concurrent microVMs, while the minimal resource footprint allows **high-density deployment on single hosts**[⁶](https://aws.amazon.com/blogs/opensource/firecracker-open-source-secure-fast-microvm-serverless/). #### Persistent state management AI agents require **stateful development environments** that maintain installed packages, file systems, and project state across sessions. Firecracker's VM-based architecture provides **native filesystem persistence** without requiring complex external state management systems, supporting E2B's up to 24-hour session duration. --- ## Technical challenges ### Achieving fast cold starts with full VM isolation The **cold start problem** represents a fundamental challenge for AI code execution platforms: the latency between a user request and when code can actually execute. Traditional solutions force a choice between **security** (slow VM startup) or **speed** (fast but vulnerable containers). - **Containers**: Fast startup (~50-200ms) but **shared kernel vulnerabilities** - **Traditional VMs**: Strong isolation but **slow startup (seconds)** and high memory overhead (~131MB) - **Required solution**: VM-level security with container-like performance By leveraging Firecracker's microVM technology, E2B achieves **<200ms sandbox initialization** and "effectively eliminate cold starts" for AI applications, providing immediate responsiveness while maintaining VM-level security isolation required for untrusted code execution. **Further optimizations:** - **Pre-warmed infrastructure**: E2B maintains ready microVM pools to reduce allocation latency - **Hardware isolation with minimal overhead**: Firecracker's ~5 MiB memory footprint enables high-density deployments - **Session persistence**: Up to 24-hour session duration eliminates repeated cold starts for ongoing workflows ### Template-based environment provisioning and VM pooling E2B implements a **sophisticated template-based resource management system** that enables efficient resource reuse through pre-built, snapshotted environments that can be rapidly instantiated multiple times. #### Template creation and snapshotting **Template build process** Templates are created using the `e2b template build` command, which builds sandbox templates from Dockerfiles and converts them to microVM snapshots. The system uses an `e2b.toml` configuration file to store template metadata including resource specifications with configurable CPU and memory settings. Docker images serve as **build artifacts** during template creation but are converted to Firecracker microVM snapshots for runtime execution. **Template lifecycle process** The template creation process involves several key steps that optimize resource utilization: ```mermaid graph TD A[Dockerfile Input] --> B[Docker Image Build] B --> C[Convert to MicroVM] C --> D[Dependency Installation] D --> E[Start Command Execution] E --> F[Environment Readiness Check] F --> G[VM State Snapshotting] G --> H[Template Ready for Use] B1[Standard Docker build
process] --> B C1[Convert Docker image
to Firecracker microVM] --> C E1[Pre-initialize services
Seed databases] --> E F1[Verify all services
running correctly] --> F G1[Serialize complete VM state
Save as reusable snapshot] --> G ``` This process transforms a standard Dockerfile into a **pre-configured, snapshotted microVM** that can be instantly restored without rebuilding. The final output is a Firecracker microVM snapshot, not a container image. **Snapshotting technology** This snapshotting approach captures the complete running state, including all processes and filesystem changes, allowing for **near-instantaneous restoration** and eliminating the need to rebuild environments from scratch for each sandbox. #### Node-based orchestration and resource management **Cluster resource tracking** E2B manages resources through a cluster of nodes, where each node monitors: - **CPU allocation**: Total CPU cores allocated across running sandboxes - **Memory tracking**: Real-time memory usage across all instances - **Sandbox capacity**: Current running instances and sandboxes being started **Local template caching** Each cluster node maintains **locally cached templates** - pre-built environments stored locally for immediate sandbox creation, reducing startup latency by eliminating the need to fetch and prepare VM images from remote storage. **Node state management** The platform employs a **node-based orchestration system** for managing sandboxes across a distributed cluster. Each node tracks critical metrics including allocated CPU cores, allocated memory, sandbox count, and operational status: ```mermaid graph TB subgraph "Node Orchestration System" subgraph "Node States" Ready[Ready
Available for workloads] Draining[Draining
Completing existing work] Connecting[Connecting
Joining cluster] Unhealthy[Unhealthy

Sandbox creation requests specify template ID and resource parameters, allowing the orchestrator to schedule VMs on appropriate nodes based on available capacity. #### Advanced resource optimization **Start command pre-initialization** Templates support start commands that pre-initialize services and applications, reducing runtime startup overhead. This feature allows running servers or seeded databases to be ready immediately when spawning sandboxes, eliminating wait times during runtime. **Pause and resume functionality** The system supports pause and resume functionality, allowing VMs to be temporarily suspended while preserving state, effectively extending the pre-warmed pool concept to running instances. **Template management operations** E2B provides comprehensive template management through CLI commands: - **Template listing**: View all templates with their resource allocations - **Template publishing**: Share templates across teams for resource standardization - **Template deletion**: Clean up unused templates to free resources This template-based architecture represents a sophisticated approach to environment reuse that significantly reduces resource overhead compared to traditional container-per-request models, enabling **sub-second sandbox startup times** while maintaining full isolation between instances. --- ## Security and isolation models E2B implements a **multi-layered security and isolation model** that combines Firecracker microVM isolation, dual authentication mechanisms, and secure communication protocols to provide safe execution environments for AI agents. ### Authentication and access control #### Dual authentication model E2B uses a **dual authentication architecture** where API keys authenticate with the main API while access tokens secure communication with individual sandbox environments: ```mermaid graph TB subgraph "E2B Security Architecture" Client[AI Agent/Client] --> API[Main API Server] API --> |API Key Auth| Lifecycle[Sandbox Lifecycle] API --> |Generate| Token[Access Token] Token --> |Secure Auth| Sandbox1[Sandbox Environment 1] Token --> |Secure Auth| Sandbox2[Sandbox Environment 2] subgraph "Sandbox Security" Sandbox1 --> EnvD1[Environment Daemon] Sandbox2 --> EnvD2[Environment Daemon] EnvD1 --> MicroVM1[Firecracker MicroVM] EnvD2 --> MicroVM2[Firecracker MicroVM] end subgraph "Communication Protocols" REST[REST API
Lifecycle Management] GRPC[gRPC Protocol
Real-time Operations] end API --> REST Token --> GRPC end ``` **Optional Secure Mode** The system supports an **optional secure mode** that requires access token authentication for all sandbox operations. When enabled, this mode generates per-sandbox access tokens that must be included in all subsequent requests. #### MicroVM-based isolation Each sandbox runs as an **isolated Firecracker microVM** with its own environment daemon (`envd`) that provides secure access to filesystem, process, and terminal operations. The sandboxes are built from **Docker images** that are converted to microVM snapshots through customizable templates, providing VM-level security boundaries while maintaining rapid startup capabilities. ### Secure communication architecture #### Dual protocol design The platform uses **dual protocols** for different types of operations: - **REST API**: Sandbox lifecycle management (create, kill, timeout) with API key authentication - **gRPC Protocol**: Real-time operations (filesystem, commands, terminals) with access token authentication All gRPC communications include authentication headers when access tokens are available, ensuring secure communication channels between clients and sandbox environments. #### Network security All communications use **HTTPS/TLS encryption** for data in transit, with the system automatically switching between HTTP (debug mode) and HTTPS (production) based on configuration. ### File access security #### **Signature-based access control** E2B implements **signature-based file access control** for enhanced security. In secure mode, file upload and download operations require cryptographic signatures that include the file path, operation type, user, and access token. **Time-limited access** The signature system supports **time-limited access** with configurable expiration times, providing fine-grained control over file access permissions. Without proper signatures in secure mode, file access requests are rejected with authentication errors. ### Runtime environment isolation #### Multi-layer isolation architecture E2B implements **defense-in-depth isolation** through multiple security boundaries, from hardware to application level: ```mermaid graph TB subgraph "E2B Isolation Layers" subgraph "Layer 4: Application Security" App1[AI Agent Code] App2[User Processes] EnvD[Environment Daemon

The environment daemon runs on a dedicated port (49983) within each microVM and manages all interactions within the sandbox. #### VM snapshotting technology E2B leverages **VM snapshotting technology** that allows the entire VM state (filesystem + running processes) to be serialized and restored in **~150ms**. This enables rapid instantiation of pre-configured environments while maintaining complete isolation between sandboxes. #### Lifecycle management Sandboxes have **timeout-based lifecycle management** where microVMs are automatically terminated after a specified duration, providing resource cleanup and preventing long-running processes from consuming system resources indefinitely. --- ## Infrastructure and scaling patterns E2B's infrastructure design enables **scalable AI code execution** by building upon the technical foundations described earlier. The platform's scaling strategy leverages its **Firecracker microVM architecture**, **template-based provisioning**, and **node orchestration** to support diverse workload patterns[¹¹](https://deepwiki.com/e2b-dev/E2B). ### Scaling architecture overview Building on the **template lifecycle** and **node orchestration** systems detailed in the technical challenges section, E2B's infrastructure supports both horizontal and vertical scaling patterns: ```mermaid graph TB subgraph "E2B Scaling Strategy" subgraph "Foundation Layer (Covered in Technical Challenges)" Templates[Template Creation

Dify breakdown

[Dify.ai](https://dify.ai/) represents a significant advancement in LLM application development, evolving from a simple workflow builder to a comprehensive production platform serving **180,000+ developers** and powering enterprise AI deployments at banks and tech companies. The platform's Beehive architecture enables modular, scalable development while its visual workflow builder democratizes AI application creation for both technical and non-technical teams. With **100k+ GitHub stars** and releases every 2-4 weeks, Dify has established itself as the leading open-source alternative to proprietary AI development platforms, offering a unique combination of no-code accessibility and production-grade infrastructure. ![](assets/dify.gif) ## Overall system architecture ![](assets/dify-architecture.webp) ## Visual AI development at scale Dify addresses a fundamental challenge in AI development: the gap between rapid prototyping and production deployment. While tools like LangChain excel at providing flexible code-based components, and platforms like OpenAI's Assistants API offer powerful but vendor-locked solutions, Dify occupies a unique position as a **complete production platform** that maintains flexibility without sacrificing ease of use. The platform enables three primary capabilities that define modern AI applications. First, it provides **visual workflow orchestration** through a drag-and-drop canvas where complex AI logic can be designed, tested, and deployed without writing code. Second, it offers **comprehensive RAG pipelines** that handle everything from document ingestion to semantic search with hybrid retrieval strategies. Third, it delivers **agent orchestration** with support for multiple reasoning strategies including ReAct, Function Calling, and Chain-of-Thoughts patterns. What makes Dify particularly compelling is its target audience diversity. Startups use it to rapidly validate AI ideas and build MVPs that secure funding. Established businesses integrate it through RESTful APIs to enhance existing applications with LLM capabilities while maintaining clean separation between prompts and business logic. Enterprises deploy it as an internal LLM gateway, providing centralized governance and compliance for AI adoption across departments. Even AI enthusiasts leverage it as a learning platform for understanding prompt engineering and agent architectures. ## Architecture bridges simplicity and complexity Dify's technical foundation rests on a **hexagonal Beehive architecture** introduced in version 0.4.0, representing a complete architectural transformation from its earlier monolithic design. This modular structure organizes components like cells in a beehive, where each module functions independently yet collaborates seamlessly with others. The architecture enables horizontal scaling across various application scenarios without waiting for official updates, while maintaining API consistency between different touchpoints. The platform is built on a **microservices architecture** with three core services. The API service, written in Python using Flask, handles all REST endpoints and business logic. The worker service leverages Celery for asynchronous task processing, managing everything from document indexing to model invocations. The web service delivers a Next.js-based frontend that provides the visual workflow builder and management interface. Supporting these core services is a sophisticated **data layer** comprising PostgreSQL for metadata storage, Redis for caching and message queuing, and configurable vector databases (Weaviate, Qdrant, pgvector) for embedding storage. The system also includes a custom-built DifySandbox for secure code execution and an SSRF proxy for security isolation. ## Solving critical LLM development challenges Dify addresses several technical challenges that plague LLM application development. The **model abstraction complexity** problem, where integrating multiple LLM providers requires extensive custom code, is solved through a unified Model Runtime system that provides consistent interfaces across 100+ models from dozens of providers. This abstraction layer handles credential management, token counting, streaming responses, and error handling transparently. The **workflow orchestration challenge** of coordinating complex multi-step AI processes is addressed through a graph-based execution engine with dependency resolution. This engine supports both sequential and parallel execution, enabling sophisticated patterns like map-reduce operations over document collections or parallel API calls to different models for ensemble predictions. **RAG implementation complexity** typically requires months of engineering effort to build production-quality retrieval systems. Dify provides an out-of-the-box RAG engine with sophisticated features including hybrid search (combining semantic and keyword search), parent-child retrieval for maintaining context, and multi-path retrieval strategies that achieve **20% better retrieval hit rates** than OpenAI's Assistants API. The **secure code execution problem** in AI workflows is solved through a custom sandbox environment using Linux chroot isolation. This allows users to write Python or JavaScript code within workflows while maintaining security boundaries, enabling powerful custom transformations without compromising system integrity. ## Business impact beyond technical metrics Dify's business impact manifests in three key dimensions. **Developer productivity** improvements are substantial. Teams report building their first AI applications in hours rather than weeks. The visual interface enables non-technical team members to participate in AI application design, breaking down traditional silos between business and technical teams. The platform's Backend-as-a-Service approach means developers can focus on business logic rather than infrastructure. **Cost optimization** comes through intelligent model selection and usage tracking. Organizations can compare costs across different providers, optimize prompt lengths, and implement caching strategies to reduce API calls. The ability to switch between cloud and local models provides flexibility in balancing performance against cost. **Enterprise governance** capabilities address the critical need for centralized AI management. Banks and financial institutions use Dify as an internal LLM gateway, ensuring all AI interactions comply with regulatory requirements. The platform provides comprehensive audit trails, usage analytics, and access controls that satisfy enterprise security teams. ## Competitive advantages from architecture Dify's competitive positioning reveals several key advantages over alternatives. Unlike **LangChain**, which provides a toolbox of components requiring significant coding expertise, Dify offers a complete scaffolding system with visual interfaces. While LangChain excels at flexibility for developers, Dify democratizes AI development for entire organizations. Compared to **Flowise**, another visual LLM application builder, Dify provides superior workflow iteration capabilities and a more intuitive interface for beginners. The platform's performance characteristics, handling approximately 10 QPS per pod, are adequate for most use cases, though Flowise shows better scalability in high-traffic enterprise environments. Against **OpenAI's Assistants API**, Dify's model-agnostic approach prevents vendor lock-in while providing comparable features. Organizations can use OpenAI models through Dify today and switch to open-source alternatives tomorrow without rewriting applications. The platform's **open-source nature** with a strong community (100,000+ GitHub stars) ensures rapid innovation and vendor independence. However, some licensing concerns have been raised about Dify's "Apache 2.0-like but not really" license, which allows the company to change terms for future versions. ## Technical deep-dive ### Beehive architecture for infinite extensibility ![](assets/dify-plugin-ecosystem.webp) The Beehive architecture's most clever implementation is its **plugin system with multiple runtime environments**. Located in the plugin daemon service, this system provides four distinct execution modes. The local runtime uses subprocess communication via STDIN/STDOUT for development. The debug runtime maintains TCP long connections with stateful management through Redis, enabling hot-reload during development. The serverless runtime integrates with AWS Lambda for automatic scaling in SaaS deployments. The enterprise runtime provides a controlled environment for private deployments. What makes this particularly sophisticated is the security model. Instead of restrictive sandboxing that limits functionality, Dify uses cryptographic signatures to verify plugin integrity. This allows plugins to have full capabilities while maintaining security through public-key verification. ### Workflow engine parallel processing ![](assets/dify-workflow-execution-engine.webp) The workflow engine's **parallel execution system** (`/api/core/workflow/nodes/iteration/iteration_node.py`) demonstrates engineering excellence through its thread pool management: ```python if self.node_data.is_parallel: thread_pool = GraphEngineThreadPool(max_workers=self.node_data.parallel_nums) futures = [] for item in iterator_list_value: future = thread_pool.submit(self._run_single_iteration, item) futures.append(future) # Intelligent result aggregation with error handling results = self._collect_results(futures) ``` This implementation cleverly handles both sequential and parallel execution modes, with proper resource management and error propagation. The system maintains execution context across parallel branches through a sophisticated **variable pool system** that implements hierarchical scoping. Variables can be accessed across nodes while maintaining isolation. ### Model runtime abstracts 100+ providers ![](assets/dify-model-runtime-layer.webp) The **Model Runtime abstraction** (`/api/core/model_runtime/`) provides a unified interface that makes switching between providers transparent: ```python class ModelRuntime: def invoke_llm(self, model: str, **kwargs) -> LLMResult: # Provider detection and credential management provider = self._get_provider(model) # Unified invocation with automatic retry and fallback with self._telemetry_context(): result = provider.invoke( self._transform_inputs(kwargs), streaming=kwargs.get('streaming', False) ) # Token counting and cost tracking self._track_usage(result) return self._transform_output(result) ``` This abstraction handles credential management, token counting, streaming responses, and error handling transparently across all providers. The system supports YAML-based model configuration, enabling new models to be added without code changes. ### HTTP request node intelligent file handling The **HTTP Request Node** (`/api/core/workflow/nodes/http_request/node.py`) demonstrates sophisticated file handling: ```python def extract_files(self, url: str, response: Response) -> list[File]: content_type = response.headers.get('content-type', '') # Intelligent MIME type detection and handling if content_type.startswith('image/'): return self._handle_image(response) elif content_type.startswith('application/pdf'): return self._handle_pdf(response) elif 'json' in content_type: # Extract embedded files from JSON responses return self._extract_json_files(response.json()) # Automatic file transfer to Dify's storage system file_obj = self._create_file_from_response(response) self._transfer_to_storage(file_obj) return [file_obj] ``` This implementation automatically detects file types, extracts embedded content, and seamlessly integrates with Dify's file management system, enabling workflows to process files from APIs without manual intervention. ### Code execution sandbox balances security and functionality The **Code Node** (`/api/core/workflow/nodes/code/code_node.py`) provides secure code execution: ```python def _run(self) -> NodeRunResult: # Transform variables for sandbox environment sandbox_vars = self._prepare_sandbox_variables(variables) # Execute with depth limiting and timeout result = CodeExecutor.execute_workflow_code_template( language=code_language, code=code, inputs=sandbox_vars, timeout=30, # 30-second timeout max_depth=5 # Prevent infinite recursion ) # Validate output against schema validated = self._transform_result(result, self.node_data.outputs) return NodeRunResult( status=WorkflowNodeExecutionStatus.SUCCEEDED, outputs=validated ) ``` The sandbox uses Linux chroot for isolation while maintaining access to standard libraries. This enables powerful custom transformations without compromising security, a balance many platforms struggle to achieve. ### Tool node dynamic parameter resolution The **Tool Node's** parameter generation (`/api/core/workflow/nodes/tool/tool_node.py`) showcases dynamic configuration: ```python def _generate_parameters(self, tool_parameters, variable_pool): resolved_params = {} for param in tool_parameters: if param.type == ToolParameter.ToolParameterType.SELECT: # Dynamic option resolution from variable pool options = variable_pool.get(param.options_selector) resolved_params[param.name] = self._validate_selection( param.value, options ) elif param.type == ToolParameter.ToolParameterType.FILE: # Handle file uploads with automatic conversion file_var = variable_pool.get(param.value_selector) resolved_params[param.name] = self._prepare_file(file_var) return resolved_params ``` This system enables complex parameter passing between nodes, supporting everything from simple values to file uploads and dynamic selections based on previous node outputs. ## Performance architecture scaling patterns ![](assets/dify-load-distribution.webp) Performance testing reveals Dify handles approximately **10 QPS per pod** with 1 CPU and 2GB RAM. Under load testing with 8 cores and 16GB RAM across 2 pods, the system achieves **11 requests/second without model integration** and **6 requests/second with model integration**. These numbers indicate suitability for small-to-medium workloads but highlight scaling limitations for high-traffic scenarios. The primary bottleneck is **database interaction patterns**. Each workflow node queries the database individually, creating latency in complex workflows. The community has identified this as a key area for improvement, with proposals for a Redis-based caching layer between nodes. ## Engineering decisions and trade-offs The decision to replace Poetry with UV as the package manager in v1.3.0 demonstrates pragmatic optimization. UV provides **10-100x faster** dependency resolution, significantly improving developer experience and CI/CD pipeline performance. The choice of **Flask over FastAPI** for the backend might seem counterintuitive for a modern application, but it reflects Dify's evolution from a simpler tool to a complex platform. Flask's maturity and extensive ecosystem provide stability, while the team focuses innovation efforts on the core AI capabilities rather than framework migration. The **hybrid vector database approach**, supporting Weaviate, Qdrant, pgvector, and others, acknowledges that vector search is a rapidly evolving space. Rather than betting on a single solution, Dify provides flexibility to switch as better options emerge. ## Bottlenecks and improvement paths Current bottlenecks center on three areas. **Workflow processing** becomes slow with many nodes due to synchronous database calls. The proposed solution involves implementing a caching layer and batch database operations. **Document processing** shows memory leaks with large knowledge bases, requiring optimization of the embedding pipeline and better memory management. **Horizontal scaling** is limited by stateful components. The roadmap includes moving toward stateless services and external session management. The team's transparency about these limitations builds trust. Rather than hiding weaknesses, they actively discuss them in GitHub issues and the roadmap, with clear plans for addressing each bottleneck. The v0.8.0 introduction of parallel processing and the ongoing Beehive architecture evolution demonstrate commitment to solving these challenges. ## Technical learnings for similar systems Engineers building similar platforms can extract several valuable lessons from Dify's architecture. The **plugin system's multiple runtime environments** solve the deployment flexibility challenge elegantly. Development, debugging, and production needs are addressed without compromising security or functionality. The **variable pool system with hierarchical scoping** provides a blueprint for managing state in complex workflows. This pattern enables both isolation and sharing, crucial for workflow systems where nodes need controlled access to each other's outputs. The **unified model abstraction** demonstrates how to future-proof against API changes. By centralizing provider-specific logic and exposing a consistent interface, applications remain stable even as underlying APIs evolve. The **decision to use cryptographic signatures over sandboxing** for plugin security shows innovative thinking. This approach provides better performance and functionality while maintaining security, a lesson applicable to any extensible system. ## Conclusion Dify.ai represents a sophisticated engineering achievement that successfully bridges the gap between visual simplicity and production complexity. Its Beehive architecture provides the modularity needed for enterprise scale while maintaining the accessibility that democratizes AI development. With clever implementations like the multi-runtime plugin system, parallel workflow execution, and unified model abstraction, Dify demonstrates that production-grade AI platforms can be both powerful and approachable. The platform's rapid growth (>100k GitHub stars, 180,000+ developers, and enterprise deployments) validates its architectural decisions. While performance limitations exist around database interactions and horizontal scaling, the transparent roadmap and active development (releases every 2-4 weeks) suggest these will be addressed. For organizations seeking to build LLM applications, Dify offers a compelling combination of immediate productivity and long-term flexibility, making it a strong foundation for the next generation of AI-powered systems. ## References - https://github.com/langgenius/dify - https://deepwiki.com/langgenius/dify - https://dify.ai/blog/dify-rolls-out-new-architecture - https://docs.dify.ai/en/introduction - https://dify.ai/blog/dify-plugin-system-design-and-implementation - https://dify.ai/blog/dify-ai-workflow - https://dify.ai/blog/dify-ai-rag-technology-upgrade-performance-improvement-qa-accuracy - https://dify.ai/blog/accelerating-workflow-processing-with-parallel-branch - https://github.com/langgenius/dify/discussions - https://github.com/langgenius/dify-sandbox

Maybe finance breakdown

## Overview Maybe is an open-source personal finance application originally developed as a commercial product with over $1 million in development investment. After the commercial venture ended in 2023, the codebase was open-sourced to enable individuals to manage their finances using a sophisticated, feature-rich platform. ![Demo](./assets/maybe-illu.gif) **Key components:** - **Multi-tenant family-based architecture**: Central organizational structure around families - **Multi-currency support**: Powered by Synth Finance API for exchange rates - **Financial institution integration**: Plaid API for US/EU bank connections - **Manual data management**: CSV imports and manual entry capabilities - **Investment tracking**: Securities data and portfolio management - **Self-hosting capabilities**: Complete Docker-based deployment stack ## How it works ### Application infrastructure Maybe implements a Rails 7.2 application with specialized subsystems for financial data management, external integrations, and multi-tenant organization. The architecture is built around the Family model as the central aggregate root and tenant boundary. ```mermaid graph TB %% External Integrations (top) subgraph "External Integrations" PlaidAPI["Plaid API

Each family serves as an isolated tenant with complete ownership of their financial data, users, and configurations. ```mermaid flowchart TD Family["Family (Tenant Root)"] Family --> Users Family --> Categories Family --> Tags Family --> FamilyMerchants Family --> Rules Family --> Budgets Family --> Imports Family --> InvitationsReceived["Invitations (received)"] Family --> PlaidItems Users --> Sessions Users --> InvitationsInviter["Invitations (as inviter)"] Family --> Accounts Accounts --> Entries Accounts --> Balances Accounts --> Holdings PlaidItems --> PlaidAccounts PlaidAccounts --> Accounts ``` #### Primary models **Family (Aggregate Root)** - Central tenant boundary for data isolation - Owns all financial data (accounts, transactions, categories) - Stores default currency and family-wide configuration - Enables shared access for multiple family members **User (Access Control)** - Belongs to family, inherits access to all family data - Supports multiple users per family (spouses, advisors) - No direct data ownership - all data belongs to family unit **Account (Financial Foundation)** - Uses Rails delegated types for account specialization - Supports checking, savings, credit, investment, loan, property accounts - Polymorphic design enables type-specific behavior while maintaining unified interface - Links to financial institutions via Plaid integration **Entry (Financial Events)** - Base class for all financial events using polymorphic relationships - Handles transactions, valuations, and trades through "entryable" pattern - Provides consistent chronological ordering and amount handling - Maintains family-level aggregation capabilities #### Specialized models **Transaction** - Core personal finance activity (purchases, deposits, transfers) - Automatic transfer detection prevents double-counting in budgets - Supports categorization and tagging for organization - Handles complex transfer scenarios between family accounts **Investment system** - Security: Investable assets with market data - Holding: Current positions in investment accounts - Trade: Buy/sell transactions with quantity, price, fees - Enables portfolio valuation and performance tracking **Category & tag system** - Categories: Hierarchical organization for budgeting - Tags: Flexible, non-hierarchical cross-cutting analysis - Supports both income and expense classification **Import system** - Handles CSV imports, Mint exports, other financial software - Type-specific models (TransactionImport, TradeImport, AccountImport) - Intelligent format detection and validation - Robust data migration capabilities **Institution Integration** - Institution: Financial institution metadata - PlaidItem/PlaidAccount: API integration management - Supports both automated syncing and manual entry - Fallback mechanisms for connection failures **Multi-currency support** - Consistent currency storage at account level - Family-level default currency for aggregation - Money objects handle conversion and arithmetic - Exchange rate integration for accurate cross-currency calculations ## Technical challenges #### Caching performance optimization **Multi-Layered Caching Architecture** Maybe implements a comprehensive multi-layered caching strategy to handle the performance demands of financial data processing. The core caching system is built around the Family model's cache key management, which creates cache keys that automatically invalidate when account data changes, using sync timestamps and account update times as invalidation triggers. The system also maintains separate cache versioning for entry-related calculations, ensuring that different types of financial data have appropriate invalidation strategies. ```mermaid flowchart TD %% User Entry A[User Request] --> B{HTTP ETag} %% Three Cache Layers B -->|Hit| C[304 Not Modified] B -->|Miss| D{Rails Cache} D -->|Hit| E[Return Cached Data] D -->|Miss| F{Memoization} F -->|Hit| G[Return Memoized Data] F -->|Miss| H[Execute Query] %% Data Flow H --> I[Store in All Layers] I --> J[Return Data] %% Invalidation K[Data Changes] --> L[Clear All Caches] L --> B ``` **Three-tier cache strategy** **Layer 1: HTTP ETag cache** The fastest response path uses HTTP ETags to return 304 Not Modified responses when client-side data hasn't changed. This eliminates server processing entirely for frequently accessed dashboard elements like sparklines and financial summaries, providing sub-millisecond response times. **Layer 2: Rails Cache** Server-side caching handles expensive database queries and financial calculations using intelligent cache key generation. The system uses memory store in development and Redis in production, with cache keys that automatically invalidate when underlying financial data changes through sync timestamps and account update tracking. **Layer 3: Memoization** Instance-level caching stores calculation results in Ruby instance variables during single requests. This prevents redundant balance calculations and chart data generation when the same financial metrics are accessed multiple times within a request cycle. **Smart cache key management** The caching mechanism centers around the Family model as the cache coordinator, generating composite cache keys that include family ID for multi-tenant isolation, sync completion timestamps for data-dependent invalidation, and account update times for granular cache control. This hierarchical approach ensures cache invalidation cascades appropriately from family-level changes down to individual account calculations. ### Multi-currency complexity **Challenge**: Supporting global users requires handling multiple currencies within the same family's financial data. Exchange rate fluctuations, currency conversion accuracy, and meaningful aggregation across currencies present significant technical challenges. **Solution**: The architecture stores both amount and currency for every financial entry, using the Synth Finance API for real-time exchange rates. The family's default currency serves as the base for aggregation, while individual accounts maintain their native currencies. Money objects handle conversion mathematics with proper precision. ![multi-currency-system](./assets/maybe-multi-currency.png) #### Exchange rate caching strategy **Multi-layer caching architecture** Maybe implements a sophisticated caching strategy to minimize external API calls while ensuring rate accuracy. The system employs a database-first lookup approach where exchange rates are stored locally in a dedicated ExchangeRate model. When a rate is needed, the system first checks the local cache before making external provider requests to Synth Finance API. **Cache optimization logic** The caching mechanism uses intelligent cache management where rates are stored with currency pair and date as composite keys, enabling fast lookups for historical data. The system can optionally cache newly fetched rates for future use, reducing redundant API calls for commonly requested currency pairs. Cache invalidation ensures stale rates don't affect calculations while maintaining performance benefits. #### LOCF (Last Observation Carried Forward) algorithm ``` -- Last observation carried forward (LOCF), use the most recent balance on or before the chart date LEFT JOIN LATERAL ( SELECT b.balance, b.cash_balance FROM balances b WHERE b.account_id = accounts.id AND b.date <= d.date ORDER BY b.date DESC LIMIT 1 ) last_bal ON TRUE -- Last observation carried forward (LOCF), use the most recent exchange rate on or before the chart date LEFT JOIN LATERAL ( SELECT er.rate FROM exchange_rates er WHERE er.from_currency = accounts.currency AND er.to_currency = :target_currency AND er.date <= d.date ORDER BY er.date DESC LIMIT 1 ) er ON TRUE ``` **Gap-filling strategy** LOCF represents the core algorithm for handling missing exchange rate data across weekends, holidays, and provider outages. When the system encounters missing rate data for a specific date, it automatically carries forward the most recent available rate from a previous date. **Implementation process** The LOCF algorithm iterates through each date in a target range, checking for existing rates in both database cache and external providers. When no rate is available from either source, the algorithm uses the previous rate value to fill the gap. This previous rate value is continuously updated as the algorithm progresses through the date range, ensuring continuous data coverage. **Application areas** LOCF is implemented across multiple system components. In exchange rate imports, it ensures continuous rate coverage when external providers don't return weekend or holiday data. For security price data, the same strategy fills gaps in stock and investment prices when markets are closed. In balance chart calculations, LOCF operates at the SQL level using lateral joins to find the most recent balance and exchange rate on or before each chart date. **Data consistency benefits** The LOCF strategy prevents broken financial charts and ensures consistent calculations even when external data sources have gaps. This approach is particularly crucial for time series analysis where continuous data is essential for accurate trend visualization and portfolio valuation. The algorithm maintains historical accuracy while providing seamless user experience across different market conditions and data provider limitations. ## Clever tricks and tips ### Polymorphic account architecture with delegated types The system uses Rails' delegated types pattern to implement account specialization while maintaining a unified interface. This approach enables account-type-specific behavior (credit limits for credit cards, interest rates for loans) while preserving common operations like balance calculations and transaction aggregation. ``` def balance_type case accountable_type when "Depository", "CreditCard" :cash when "Property", "Vehicle", "OtherAsset", "Loan", "OtherLiability" :non_cash when "Investment", "Crypto" :investment else raise "Unknown account type: #{accountable_type}" end end ``` ### Transfer auto-detection algorithm Maybe implements smart transfer detection that finds matching amounts and dates across family accounts. The algorithm handles processing delays and amount differences while avoiding mistakes that could wrongly classify regular transactions as transfers. ```ruby module Family::AutoTransferMatchable def transfer_match_candidates Entry.select([ "inflow_candidates.entryable_id as inflow_transaction_id", "outflow_candidates.entryable_id as outflow_transaction_id", "ABS(inflow_candidates.date - outflow_candidates.date) as date_diff" ]).from("entries inflow_candidates") .joins(" JOIN entries outflow_candidates ON ( inflow_candidates.amount < 0 AND outflow_candidates.amount > 0 AND inflow_candidates.account_id <> outflow_candidates.account_id AND inflow_candidates.date BETWEEN outflow_candidates.date - 4 AND outflow_candidates.date + 4 ) ").joins(" LEFT JOIN transfers existing_transfers ON ( existing_transfers.inflow_transaction_id = inflow_candidates.entryable_id OR existing_transfers.outflow_transaction_id = outflow_candidates.entryable_id ) ") .joins("LEFT JOIN rejected_transfers ON ( rejected_transfers.inflow_transaction_id = inflow_candidates.entryable_id AND rejected_transfers.outflow_transaction_id = outflow_candidates.entryable_id )") .joins("LEFT JOIN exchange_rates ON ( exchange_rates.date = outflow_candidates.date AND exchange_rates.from_currency = outflow_candidates.currency AND exchange_rates.to_currency = inflow_candidates.currency )") .joins("JOIN accounts inflow_accounts ON inflow_accounts.id = inflow_candidates.account_id") .joins("JOIN accounts outflow_accounts ON outflow_accounts.id = outflow_candidates.account_id") .where("inflow_accounts.family_id = ? AND outflow_accounts.family_id = ?", self.id, self.id) .where("inflow_accounts.status IN ('draft', 'active')") .where("outflow_accounts.status IN ('draft', 'active')") .where("inflow_candidates.entryable_type = 'Transaction' AND outflow_candidates.entryable_type = 'Transaction'") .where(" ( inflow_candidates.currency = outflow_candidates.currency AND inflow_candidates.amount = -outflow_candidates.amount ) OR ( inflow_candidates.currency <> outflow_candidates.currency AND ABS(inflow_candidates.amount / NULLIF(outflow_candidates.amount * exchange_rates.rate, 0)) BETWEEN 0.95 AND 1.05 ) ") .where(existing_transfers: { id: nil }) .order("date_diff ASC") # Closest matches first end ``` ``` def auto_match_transfers! # Exclude already matched transfers candidates_scope = transfer_match_candidates.where(rejected_transfers: { id: nil }) # Track which transactions we've already matched to avoid duplicates used_transaction_ids = Set.new candidates = [] Transfer.transaction do candidates_scope.each do |match| next if used_transaction_ids.include?(match.inflow_transaction_id) || used_transaction_ids.include?(match.outflow_transaction_id) Transfer.create!( inflow_transaction_id: match.inflow_transaction_id, outflow_transaction_id: match.outflow_transaction_id, ) Transaction.find(match.inflow_transaction_id).update!(kind: "funds_movement") Transaction.find(match.outflow_transaction_id).update!(kind: Transfer.kind_for_account(Transaction.find(match.outflow_transaction_id).entry.account)) used_transaction_ids << match.inflow_transaction_id used_transaction_ids << match.outflow_transaction_id end end end ``` ### Git-Style checkpoint system for financial data The application implements a checkpoint system similar to Git commits, allowing users to create snapshots of their financial state before major changes. This enables safe experimentation with categorization rules and import processes with reliable rollback capabilities. #### Anchor-based balance management ```mermaid flowchart TD %% Account Types A[Account Created] --> B{Account Type} B -->|Manual| C[Opening Anchor] B -->|Linked| D[Current Anchor] %% Calculation Direction C --> E[Forward Calculation] D --> F[Reverse Calculation] %% Balance Flow E --> G[Opening Balance + Transactions = Current Balance] F --> H[Current Balance - Transactions = Historical Balance] %% Anchor System Benefits subgraph "Anchor Benefits" I[Reference Points] J[Safe Rollback] K[Data Integrity] end %% Immutable Foundation G --> L[Immutable Entry Ledger] H --> L L --> I L --> J L --> K %% User Experience I --> M[Experiment Safely] J --> M K --> M ``` **Core anchor system architecture** Maybe's checkpoint-like functionality is built on an anchor-based balance management system through the `Account::Anchorable` concern. This system uses two types of anchors as reference points: Opening anchors that establish starting balances when accounts are first created, and Current anchors that track the most recent balance state, particularly for accounts linked to external providers like Plaid. **Dual calculator strategy** The system implements two distinct balance calculation strategies depending on account management approach. The `Forward Calculator` is used for manual accounts where users enter transactions directly, calculating balances chronologically from entries starting from zero or an opening anchor. The `Reverse Calculator` is used for linked accounts that sync from external providers, starting with the current balance and calculating backwards to derive historical balances. **Balance update management** implements different strategies based on account characteristics. For cash accounts without reconciliations, the Transaction Adjustment Strategy adjusts the opening balance by calculating the delta needed to reach the desired current balance, preventing timeline clutter with unnecessary reconciliation entries. For accounts with existing reconciliations, the Value Tracking Strategy appends new reconciliation valuations to track value changes over time. #### Entry-based immutable ledger **Immutable financial records** Rather than traditional git-style commits, Maybe uses an entry-based ledger where all financial events (transactions, trades, valuations) are stored as immutable Entry records. This approach creates a complete audit trail without requiring explicit checkpoints, as the balance calculators can process these entries to derive account balances at any point in time. **Checkpoint-like functionality** The anchor system provides checkpoint-like functionality while being specifically optimized for financial data management. Unlike git's commit-based history, Maybe's system maintains continuous balance calculations and supports both forward and reverse synchronization patterns needed for manual entry and external data integration scenarios. **Safe experimentation framework** Users can safely experiment with categorization rules and import processes because the immutable entry system preserves the original financial data. The anchor points serve as stable reference points that enable rollback capabilities, allowing users to revert changes without losing historical accuracy or data integrity. ### Smart import template suggestions The import system learns from previous successful imports, suggesting column mappings and configurations based on similar import types and file formats. This reduces repetitive configuration for users who regularly import data from the same sources. The system searches for templates using these criteria: - Same family - Same import type (TransactionImport, TradeImport, etc.) - Same target account (if specified) - Completed status only - Most recent first ## Conclusion Maybe Finance demonstrates how sophisticated financial software can be built using Ruby on Rails while maintaining focus on accuracy, usability, and architectural clarity. The open-sourcing of this million-dollar codebase provides valuable insights into production-grade financial application development. The architecture successfully balances complexity and maintainability through careful domain modeling, intelligent automation, and user-centric design. The multi-tenant family structure, polymorphic account system, and transfer-aware transaction handling represent thoughtful solutions to common personal finance software challenges. While the original company has pivoted away from personal finance, the open-source codebase continues to serve as an excellent reference implementation for developers building financial applications. The emphasis on self-hosting capabilities and manual data management makes Maybe particularly valuable for users who prioritize data ownership and privacy in their financial management tools. The codebase exemplifies how modern web applications can handle complex financial domains while maintaining clean, testable, and deployable architecture suitable for both individual use and community-driven development.

The platform operates through **four integration layers**: 1. **Client-side tracker** for data collection 2. **API endpoints** for data processing and validation 3. **Database layer** with multi-engine support 4. **Analytics engine** for report generation and visualization ### Database architecture The system supports **three database engines** to accommodate different scale requirements: - **PostgreSQL** and **MySQL** for standard deployments with full relational capabilities - **ClickHouse** for high-volume analytics with columnar storage optimization ### Data structure design The platform employs a **hierarchical data model** optimized for analytics performance: #### Core entities: - `User` and `Team` for access management and multi-tenant support - `Website` for tracking configuration and ownership - `Session` for visitor identification with device and location data - `WebsiteEvent` for all user interactions and page views - `EventData` and `SessionData` for custom analytics parameters - `Report` for saved analytics configurations The database schema includes **strategic indexing** on time-based queries and website-specific lookups to ensure optimal query performance across millions of analytics events. #### Performance infrastructure: **ClickHouse integration**: For high-scale deployments, Umami supports ClickHouse for analytics workloads. This includes optimized query functions for time-series data and advanced filtering capabilities. ```typescript function getUTCString(date?: Date | string | number) { return formatInTimeZone(date || new Date(), 'UTC', 'yyyy-MM-dd HH:mm:ss'); } function getDateStringSQL(data: any, unit: string = 'utc', timezone?: string) { if (timezone) { return `formatDateTime(${data}, '${CLICKHOUSE_DATE_FORMATS[unit]}', '${timezone}')`; } return `formatDateTime(${data}, '${CLICKHOUSE_DATE_FORMATS[unit]}')`; } function getDateSQL(field: string, unit: string, timezone?: string) { if (timezone) { return `toDateTime(date_trunc('${unit}', ${field}, '${timezone}'), '${timezone}')`; } return `toDateTime(date_trunc('${unit}', ${field}))`; } function getDateQuery(filters: QueryFilters = {}) { const { startDate, endDate, timezone } = filters; if (startDate) { if (endDate) { if (timezone) { return `and created_at between toTimezone({startDate:DateTime64},{timezone:String}) and toTimezone({endDate:DateTime64},{timezone:String})`; } return `and created_at between {startDate:DateTime64} and {endDate:DateTime64}`; } else { if (timezone) { return `and created_at >= toTimezone({startDate:DateTime64},{timezone:String})`; } return `and created_at >= {startDate:DateTime64}`; } } return ''; } ``` **Caching strategy**: Redis-based caching reduces database load for frequently accessed data, while JWT tokens enable stateless session management. ```typescript const cacheHeader = request.headers.get('x-umami-cache'); if (cacheHeader) { const result = await parseToken(cacheHeader, secret()); if (result) { cache = result; } } ``` **Kafka streaming**: For enterprise deployments, Kafka integration enables real-time event processing and horizontal scaling. ```typescript async function sendMessage( topic: string, message: { [key: string]: string | number } | { [key: string]: string | number }[], ): Promise { try { await connect(); return producer.send({ topic, messages: Array.isArray(message) ? message.map(a => { return { value: JSON.stringify(a) }; }) : [ { value: JSON.stringify(message), }, ], timeout: SEND_TIMEOUT, acks: ACKS, }); } catch (e) { console.log('KAFKA ERROR:', serializeError(e)); } } ``` ### Data access layer Umami implements a sophisticated data access layer that abstracts database differences. The `rawQuery` function handles parameterized queries across different database types: ```typescript async function rawQuery(sql: string, data: object): Promise { if (process.env.LOG_QUERY) { log('QUERY:\n', sql); log('PARAMETERS:\n', data); } const db = getDatabaseType(); const params = []; if (db !== POSTGRESQL && db !== MYSQL) { return Promise.reject(new Error('Unknown database.')); } const query = sql?.replaceAll(/\{\{\s*(\w+)(::\w+)?\s*}}/g, (...args) => { const [, name, type] = args; const value = data[name]; params.push(value); return db === MYSQL ? '?' : `$${params.length}${type ?? ''}`; }); return process.env.DATABASE_REPLICA_URL ? client.$replica().$queryRawUnsafe(query, ...params) : client.$queryRawUnsafe(query, ...params); } ``` This abstraction allows the same application code to work with different database backends by translating query syntax appropriately. ## Technical challenges and solutions ### Privacy protection and bot detection Umami addresses the core problem of **privacy-compliant analytics** through multiple protective mechanisms: **Do Not Track compliance**: Umami implements comprehensive Do Not Track (DNT) detection in the client-side tracker. The system checks multiple DNT sources: - Browser's `doNotTrack` property - Navigator's `doNotTrack` and `msDoNotTrack` properties - Data attribute override (`data-do-not-track="true"`) The tracking is disabled when any DNT signal equals `1`, `'1'`, or `'yes'`. Additionally, users can manually disable tracking by setting `umami.disabled` in localStorage, providing granular user control over data collection. ```typescript const hasDoNotTrack = () => { const dnt = doNotTrack || ndnt || msdnt; return dnt === 1 || dnt === '1' || dnt === 'yes'; }; ``` **Bot filtering with isbot library**: The server-side API implements sophisticated bot detection using the `isbot` npm library. When a bot is detected through user agent analysis, the system returns a playful `{ beep: 'boop' }` response instead of processing the analytics data. This filtering can be disabled via the `DISABLE_BOT_CHECK` environment variable for testing scenarios. The bot detection occurs early in the request pipeline, preventing automated traffic from polluting analytics data. **IP address handling and anonymization**: Umami implements a sophisticated IP address extraction system that supports multiple proxy headers. The system checks headers in priority order: - CloudFlare: `cf-connecting-ip` - Custom headers via `CLIENT_IP_HEADER` environment variable - Standard proxy headers: `x-forwarded-for`, `x-real-ip`, etc. For `x-forwarded-for` headers, only the first IP is extracted to avoid proxy chain pollution. The system also includes IP blocking functionality through the `IGNORE_IP` environment variable, supporting both exact matches and CIDR notation for network ranges. ```typescript export const IP_ADDRESS_HEADERS = [ 'cf-connecting-ip', 'x-client-ip', 'x-forwarded-for', 'do-connecting-ip', 'fastly-client-ip', 'true-client-ip', 'x-real-ip', 'x-cluster-client-ip', 'x-forwarded', 'forwarded', 'x-appengine-user-ip', ]; //----- export function hasBlockedIp(clientIp: string) { const ignoreIps = process.env.IGNORE_IP; if (ignoreIps) { const ips = []; if (ignoreIps) { ips.push(...ignoreIps.split(',').map(n => n.trim())); } return ips.find(ip => { if (ip === clientIp) { return true; } // CIDR notation if (ip.indexOf('/') > 0) { const addr = ipaddr.parse(clientIp); const range = ipaddr.parseCIDR(ip); if (addr.kind() === range[0].kind() && addr.match(range)) { return true; } } }); } return false; } ``` **Geolocation with privacy safeguards**: The geolocation system prioritizes privacy by first checking if the IP is localhost. For legitimate IPs, it uses a hierarchical approach: 1. **Header-based location** (CloudFlare, Vercel) for faster processing 2. **MaxMind GeoLite2 database** for IP-to-location mapping when headers unavailable The system extracts only essential geographic data (country, region, city) without storing precise coordinates. ```typescript // Database lookup if (!global[MAXMIND]) { const dir = path.join(process.cwd(), 'geo'); global[MAXMIND] = await maxmind.open(path.resolve(dir, 'GeoLite2-City.mmdb')); } // When the client IP is extracted from headers, sometimes the value includes a port const cleanIp = ip?.split(':')[0]; const result = global[MAXMIND].get(cleanIp); if (result) { const country = result.country?.iso_code ?? result?.registered_country?.iso_code; const region = result.subdivisions?.[0]?.iso_code; const city = result.city?.names?.en; return { country, region: getRegionCode(country, region), city, }; } ``` **Minimal data collection architecture**: Umami's data collection is designed around privacy-first principles. The core payload structure collects only essential analytics data: > - Website ID and screen resolution > - Page title and URL (with configurable exclusions) > - Language and referrer information > - Optional identity for user tracking The system supports URL sanitization through `excludeSearch` and `excludeHash` options, allowing websites to exclude sensitive query parameters or hash fragments from analytics. ### Performance optimization for high-volume analytics The platform handles **scale challenges** through several architectural decisions: **Session Management:** - **Unique session identification** using UUID generation with website ID, IP address, user agent, and time-based salt - **Visit expiration logic** with 30-minute timeouts to accurately track user engagement sessions - **Caching mechanism** using JWT tokens to reduce database queries for repeated requests ```typescript const sessionSalt = hash(startOfMonth(createdAt).toUTCString()); const visitSalt = hash(startOfHour(createdAt).toUTCString()); const sessionId = id ? uuid(websiteId, id) : uuid(websiteId, ip, userAgent, sessionSalt); // Find session if (!clickhouse.enabled && !cache?.sessionId) { const session = await fetchSession(websiteId, sessionId); // Create a session if not found if (!session) { try { await createSession({ id: sessionId, websiteId, browser, os, device, screen, language, country, region, city, distinctId: id, }); } catch (e: any) { if (!e.message.toLowerCase().includes('unique constraint')) { return serverError(e); } } } } // Visit info let visitId = cache?.visitId || uuid(sessionId, visitSalt); let iat = cache?.iat || now; // Expire visit after 30 minutes if (!timestamp && now - iat > 1800) { visitId = uuid(sessionId, visitSalt); iat = now; } ``` **Database Query Optimization:** - **Dual query system** supporting both relational and columnar database engines - **Parallel processing** for complex analytics reports across multiple data dimensions - **Time-based partitioning** strategies for efficient data retrieval ```typescript async function pagedQuery( query: string, queryParams: { [key: string]: any }, pageParams: PageParams = {}, ) { const { page = 1, pageSize, orderBy, sortDescending = false } = pageParams; const size = +pageSize || DEFAULT_PAGE_SIZE; const offset = +size * (+page - 1); const direction = sortDescending ? 'desc' : 'asc'; const statements = [ orderBy && `order by ${orderBy} ${direction}`, +size > 0 && `limit ${+size} offset ${+offset}`, ] .filter(n => n) .join('\n'); const count = await rawQuery(`select count(*) as num from (${query}) t`, queryParams).then( res => res[0].num, ); const data = await rawQuery(`${query}${statements}`, queryParams); return { data, count, page: +page, pageSize: size, orderBy }; } ``` ### Marketing attribution modeling Umami provides **sophisticated attribution analysis** through configurable models: - **First-click attribution** for customer acquisition analysis - **Last-click attribution** for conversion optimization ```sql ## First Click model AS (select e.session_id, min(we.created_at) created_at from events e join website_event we on we.session_id = e.session_id where we.website_id = {{websiteId::uuid}} and we.created_at between {{startDate}} and {{endDate}} group by e.session_id) ## Last Click model AS (select e.session_id, max(we.created_at) created_at from events e join website_event we on we.session_id = e.session_id where we.website_id = {{websiteId::uuid}} and we.created_at between {{startDate}} and {{endDate}} and we.created_at < e.max_dt group by e.session_id)`; ``` - **Revenue attribution** with currency-specific tracking ```sql WITH events AS ( select we.session_id, max(ed.created_at) max_dt, sum(coalesce(cast(number_value as decimal(10,2)), cast(string_value as decimal(10,2)))) value from event_data ed join website_event we on we.event_id = ed.website_event_id and we.website_id = ed.website_id join (select website_event_id from event_data where website_id = {{websiteId::uuid}} and created_at between {{startDate}} and {{endDate}} and data_key ${like} '%currency%' and string_value = {{currency}}) currency on currency.website_event_id = ed.website_event_id where ed.website_id = {{websiteId::uuid}} and ed.created_at between {{startDate}} and {{endDate}} and ${column} = {{conversionStep}} and ed.data_key ${like} '%revenue%' group by 1), ``` - **Paid advertising detection** across multiple platforms with specific parameter through click IDs and storing them to database: - Google Ads: `gclid` parameter - Facebook/Meta: `fbclid` parameter - Microsoft Ads: `msclkid` parameter - TikTok Ads: `ttclid` parameter - LinkedIn Ads: `li_fat_id` parameter - Twitter Ads: `twclid` parameter - **Attribution data analysis**: report analyzes multiple marketing dimensions: - **Referrer domains**: External websites driving traffic - **Paid advertising**: Platform-specific click ID attribution - **UTM parameters**: Campaign tracking across source, medium, campaign, content, and term - **Total metrics**: Overall pageviews, visitors, and visits for context The attribution results are displayed through specialized UI components that show both tabular data and pie charts for visual attribution analysis ## Implementation insights and best practices ### Client-side data collection strategy The tracking implementation employs **several clever techniques** for comprehensive yet unobtrusive data collection: **Automatic Event Detection:** - **History API hooking** to capture single-page application navigation without page reloads - **Click tracking** with automatic event data extraction from HTML attributes, eg: can add `data-umami-event` attributes to any element to automatically track clicks without writing JavaScript. - **Before-send callbacks** implements a flexible callback system that allows custom data validation and modification before events are sent to the server. This enables developers to: - Filter sensitive data from URLs or event parameters - Add custom metadata to all events - Implement client-side data validation rules - Transform event data based on business logic **Data Quality Assurance:** - **URL normalization** with configurable search parameter and hash exclusion - **Search parameter exclusion**: The system supports configurable exclusion of URL search parameters through `excludeSearch` options, preventing sensitive query parameters from being tracked. - **Hash fragment handling**: Hash fragments can be optionally excluded via `excludeHash` configuration, useful for applications that use hash routing but don't want to track fragment changes. - **Referrer validation** to distinguish internal from external traffic sources - **Domain filtering** for multi-site deployments with centralized analytics ### Revenue and conversion tracking The platform handles **complex e-commerce analytics** through flexible event data structures: - **Multi-currency support** with automatic currency detection and conversion calculation - **Custom event parameters** for detailed transaction and user behavior analysis - **Attribution modeling** linking revenue events back to marketing touchpoints, that enabling businesses to: - Track revenue by marketing channel - Calculate return on advertising spend (ROAS) - Analyze conversion value across different traffic sources - Support both first-click and last-click revenue attribution models --- Umami represents a **comprehensive solution** for privacy-focused web analytics that successfully balances detailed business intelligence with user privacy protection. The platform's **multi-database architecture** ensures scalability from small websites to enterprise-level deployments, while its **extensible report system** provides the analytical depth required for data-driven decision making. The system's **dual query implementation** for both relational and columnar databases demonstrates sophisticated technical architecture that maintains consistent functionality across different performance and scale requirements. This approach ensures optimal performance whether processing thousands or millions of analytics events.

Markdown lint

Maintaining a healthy knowledge base requires attention to detail: consistent headings, complete frontmatter, valid links, and stylistic coherence over time. However, enforcing quality across a multi-repository system—where content is authored by many contributors and rules evolve—presents a significant challenge. We address this complexity through a sophisticated Markdown linting and formatting pipeline, integrating traditional rule engines with generative AI to ensure consistency and efficiency. ## Why automate markdown quality? Initially, relying on contributors to follow conventions might seem sufficient. However, as our knowledge base expanded, we encountered increasing entropy: inconsistent headings, missing metadata, broken links, and gradual stylistic divergence. Manual review became unsustainable, driving us to develop a system capable of: - Enforcing structural integrity (frontmatter completeness, heading levels, link validity) - Standardizing stylistic elements (sentence case, Prettier formatting) - Seamlessly integrating with local developer workflows and CI/CD pipelines - Adapting to evolving rules and diverse content types ## Modular linting: rules as code We developed a modular linting engine that dynamically loads rule modules from `scripts/formatter/rules/`. Each rule is implemented as a TypeScript file following a standardized interface: it analyzes files, reports violations, and optionally provides automated fixes. Our current rule set includes: - **Frontmatter validation**: Guarantees every note contains required fields (`title`, `description`, `date`), proper YAML structure, and canonical field ordering. - **No H1 headings**: Prohibits the use of `#` level headings in content, ensuring titles are consistently sourced from frontmatter. - **Relative link existence**: Verifies that all relative links within content point to valid, existing files. - **Prettier formatting**: Applies Prettier across the entire file, leveraging project-specific configuration when available. - **Sentence case via LLM**: Utilizes OpenRouter (GPT-4) to convert headings, titles, and key phrases to sentence case while intelligently preserving proper nouns and acronyms. This linting system operates flexibly, capable of processing any file set recursively or by pattern, and offers straightforward extensibility—new rules can be added simply by dropping additional TypeScript files into the `rules/` directory. ## How does lint work? The cornerstone of our linting system is `scripts/formatter/note-lint.ts`, a TypeScript module that orchestrates the entire linting and formatting process through these key steps: 1. **File discovery:** Accepts file paths or glob patterns, recursively identifying all Markdown files requiring linting. 2. **Config loading:** Dynamically loads linting rules from `.notelintrc.js`, `.notelintrc.json`, or `package.json` if present, otherwise falling back to a default configuration. 3. **Rule execution:** For each file, parses frontmatter and content, then sequentially executes each rule module. Rules can report errors, warnings, and optionally provide auto-fixes. 4. **Auto-fixing:** When executed with `--fix` or within git hook/CI contexts, applies all available fixes—including Prettier formatting and LLM-based sentence case—then stages changes using `git add`. 5. **Reporting:** Generates a comprehensive summary of errors, warnings, and fixes printed to the console. In CI environments, it sets outputs for GitHub Actions to facilitate auto-commit and PR comment generation. 6. **Extensibility:** New rules can be seamlessly integrated by adding a file to the `rules` directory and updating the index. This modular, rule-driven methodology enables us to enforce structural integrity, stylistic consistency, and even AI-powered conventions across thousands of Markdown files—both locally and in CI—without requiring manual intervention. ## Generative formatting: LLMs in the loop A particularly innovative aspect of our system is the integration of generative models for style normalization. The `sentence-case.ts` rule extracts all headings, frontmatter titles, and key phrases, then leverages OpenRouter's GPT-4 API to convert them to sentence case. This process intelligently preserves acronyms and proper nouns while maintaining stylistic consistency—a subtle yet powerful approach to standardization, especially as new content and contributors join the ecosystem. This methodology operates recursively: the linter extracts content, the LLM rewrites it, and the linter applies the changes. If the API key is unavailable locally, the rule gracefully skips execution; however, it always runs in CI environments to ensure consistent quality. ## Markdown lint overview ![overview-markdown-lint](assets/markdown-lint.png) ### Git hooks: local enforcement To proactively identify and resolve issues before they reach the repository, we employ a sophisticated shell-based Git hook manager (`scripts/git-shell-hook.ts`). This script transcends simple hook installation—it orchestrates a robust, recursive, and self-updating system for Markdown quality enforcement across all submodules. The system operates through these key capabilities: - **Recursive submodule discovery:** Identifies all Dwarves Foundation submodules by parsing `.gitmodules` files and exploring nested submodule structures. - **Standalone hook script generation:** Produces dedicated hook scripts (`pre-commit-hook.sh`, `pre-push-hook.sh`, etc.) within each submodule, containing embedded logic to fetch and execute the latest linting script from a trusted URL. - **Comprehensive documentation:** Creates a README for each hook, detailing usage instructions, troubleshooting guidance, and security considerations. - **Flexible command handling:** Manages install, remove, and status operations for each hook, both from the root repository and within individual submodules. - **GitHub Actions workflow integration:** Supports automated generation of GitHub Actions workflows to ensure CI/CD parity. The hooks themselves are engineered for resilience: they retrieve the latest linting script on every execution, support both TypeScript and JavaScript execution environments, and automatically update as the central linting logic evolves. This design ensures that every commit—across every submodule—adheres to the same Markdown quality standards with minimal manual oversight. ### GitHub Actions: CI for markdown everywhere For continuous integration, the same `scripts/git-shell-hook.ts` script generates tailored GitHub Actions workflows for each submodule. These workflows operate through a defined sequence: 1. **Script acquisition:** Downloads the latest linting script (available in both TypeScript and JavaScript formats). 2. **Environment setup:** Installs necessary dependencies, including `tsx` for TypeScript execution environments. 3. **Change detection:** Identifies modified Markdown files within pull requests or push events. 4. **Linting execution:** Runs the linter, applying Prettier and sentence case fixes automatically when required. 5. **Automated updates:** Auto-commits and pushes formatting changes back to the pull request branch. 6. **Feedback mechanism:** Posts a persistent PR comment summarizing all applied modifications. The workflow architecture emphasizes modularity, allowing triggering via push events, pull requests, or manual dispatch. It securely manages sensitive information like the OpenRouter API key and executes formatting steps only when necessary, optimizing both performance and resource utilization. ## Lessons and open questions Our implementation has yielded several key insights: - **Rule modularity is fundamental.** Adding or updating a rule simplifies to editing a single file—eliminating the need to modify the linter's core functionality. - **Cross-repository consistency is achievable.** By generating hooks and workflows for every submodule, we maintain high standards uniformly across all repositories, not merely the primary repository. - **Automation potential remains vast.** We are actively exploring how LLMs could further enhance our workflows through applications like link rewriting, automated summary generation, and even changelog composition. This approach ensures we maintain both structural integrity and stylistic coherence across our knowledge base while continuously exploring new frontiers for automation and enhancement.

Monitoring the ICY Swap backend

In most software, monitoring is an accessory. For a system that moves money, like a crypto swap service, it's a core part of the engine. If your gauges are wrong, the engine is broken. When building the observability for the ICY Backend, our problem wasn't just to see if the server was 'up.' It was to build a nervous system for it, one that could feel its own state without revealing secrets that would be financially fatal. ## What not to measure This led us to the central tension: we needed total observability but also near-total secrecy. Most monitoring thrives on detailed labels like user IDs. In crypto, a wallet address isn't just a label; it's a key. Exposing it in a dashboard would be like engraving your bank password on the outside of your house. So our first principle was ruthless selectivity. Metric cardinality became a security feature, not just a technical one. The rule was absolute: no transaction hashes, no addresses, no amounts. Our metrics could show what operation failed, but never for whom or for how much. ## The shape of a request So if we can’t use the most revealing labels, what is left to measure at the system’s front door, its HTTP API? The question becomes finding the most expressive yet safe dimensions of a request. We found the answer in the three primary colors of web service observability: rate, errors, and duration. These tell you almost everything you need to know about the load on the system and its ability to cope. We captured them with a few fundamental metrics. A counter for total requests, a histogram for request duration, and a gauge for active requests. The power, as always, was in the labels. We settled on three: the HTTP method, the endpoint template, and the resulting status code. This combination is powerful. It lets you ask questions like, "What is the 95th percentile latency for POST requests to /swaps that result in a 200 status?" without ever touching sensitive data. ![alt text](assets/icy-swap-http.png) The key insight here was in the endpoint label. We couldn't use the raw request path, like `/api/v1/user/123/transactions`, because that would create a new metric series for every user, defeating our security goal. Instead, we instrumented the router to provide the normalized path template: `/api/v1/user/:id/transactions`. This small distinction is what makes high-utility HTTP metrics possible in a secure environment. And the gauge for active requests turned out to be surprisingly insightful. While rate and duration tell you what has already happened, the number of active requests tells you about pressure in the system right now. If it starts climbing while the request rate stays flat, you know something is slowing down. It’s an early warning sign of saturation, a leading indicator of trouble. ## What is health? The next question was, how do you know if the system is truly healthy? A simple /healthz endpoint is trivial; it's like checking for a pulse. It confirms the system is alive, but not that it can do any real work. So we built a richer set of probes, a form of synthetic monitoring designed for an external service like Uptime Robot to watch. Instead of one status, our dashboard shows several vital signs. The first is the simple pulse check (/healthz). We then added another, `/api/v1/health/db`, to ask a more meaningful question: "Can you talk to your database?" The trickiest part is handling unreliable external APIs. Treating a failure from the Bitcoin network like a local one would cause unnecessary downtime. This is where the circuit breaker pattern is critical. It gracefully isolates external failures, preventing them from taking down our whole system. Our health check for these services, `/api/v1/health/external`, uses this logic. If a circuit is open, it reports a "degraded" status, not "unhealthy." ![alt text](assets/icy-swap-healthz.png) This gives our Uptime Robot dashboard a richer vocabulary. It’s no longer just green or red, but also has a yellow light for when the system is "wounded, but alive", giving a much more accurate picture of its state. ## Gauges on the outside world But these health checks, these green and yellow lights, are just a summary. They tell you if something is wrong, but not how wrong. A service being "degraded" is useful information, but is it slow? Is it erroring out? Is the circuit breaker about to trip again? To answer these questions, you need quantitative data. This is where we go beyond the simple status check and measure the performance of every single call to an external service. We created a standard set of Prometheus metrics for this purpose. A histogram, `icy_backend_external_api_duration_seconds`, to track latency. A counter, `icy_backend_external_api_calls_total`, to track the rate of calls and their success or failure status. And most importantly, a gauge, `icy_backend_circuit_breaker_state`, that explicitly reports whether each circuit is closed (1), open (0), or half-open (0.5). ![alt text](assets/icy-swap-metrics-external.png) This is what we plot in Grafana. It gives us a high-fidelity view of our dependencies. We can see the latency to the Bitcoin API begin to creep up minutes before our circuit breaker trips. We can overlay our application's error rate with the external API's error rate and see a direct correlation. These graphs tell a story. They don't just tell us that a service is degraded; they show us the precise shape of its degradation. This is the difference between knowing a storm is coming and having a weather radar to track its every move. ## The silent workers The most subtle layer of health, however, was in the background. A great deal of the work in a crypto system, such as indexing new transactions and processing swaps, happens in cron jobs. These are silent workers. They can fail, or worse, become stuck in an infinite loop, consuming resources without anyone noticing until it’s too late. How do you monitor something that has no user-facing request? ![alt text](assets/icy-swap-job-metrics.png) Our solution was a thread-safe manager that every job had to check in with. When a job started, it registered itself. When it finished, it reported its status as either success or failure. We built a watchdog to detect jobs running for an unusually long time, for example more than 15 minutes for a swap process, and flag them as “stalled.” This brought our background processes, the most hidden part of the machine, into the light. ## The cost of watching Of course, all this watching comes at a cost. Every check, every metric, every log adds a tiny bit of overhead. In a high-frequency financial system, nanoseconds matter. We set ourselves an almost absurdly low budget for the overhead of our main HTTP monitoring middleware: less than 1 millisecond per request. Achieving this felt like tuning a race car engine. We pre-computed metric labels at startup so we weren't doing string manipulation on every request. We were careful about memory allocations. The final result was an overhead of around 493 nanoseconds per request. This number wasn't just a performance metric; it was proof that observability didn't have to come at the expense of speed. We could have our microscope without slowing down the patient. ## What we learned What we built feels less like a collection of tools and more like a coherent system. We learned that security must be designed in from the start, not sanitized later. That "health" is not one question, but a series of layered ones. And that you must assume the world will fail, and build mechanisms like circuit breakers to survive. The work isn't finished. The next frontier is moving from passive observation to active response, like distributed tracing or automated recovery. But what we've built is a solid foundation: an engine where the gauges are part of the design, not just bolted on.

The Coding Agent Team

## Thinking in teams I recently got a request to "track user visits to more pages," which sounded simple. But it unraveled into questions about scope, performance, and privacy that most AI coding assistants can't handle. They're great for writing a single function, but ask for a full feature, and they start losing context. My own attempts felt like this. Using a single AI was like having a distractible intern doing everything from architecture to QA. It was clear I was on a path to building the wrong solution. The problem wasn't the AI's capability, but my approach. I was asking a soloist to perform a symphony. It finally clicked for me that you can’t expect one person to do the work of an entire engineering department. You have to build a team. That sparked a thought: what if AI was organized as a group of specialists? One agent could handle research, another could focus on planning, and another on testing. It reflects how we approach building software, and it seemed like a promising direction to take. ## The Five-phase flow This led me to design a workflow with five distinct agent roles, organized into a five-phase process. The key idea is that the agents don't all talk to each other at once. That would be chaos. Instead, they work sequentially, each producing documentation that becomes the input for the next. The system is managed by a master orchestrator that handles the handoffs, much like a project manager ensuring each person has what they need to start their work. It looks something like this: 1. **Analyze & Research:** A Researcher agent digs into the problem space. 2. **Planning:** A Project Manager agent creates architectural plans and specifications. 3. **Test Case Design:** A Test Case Designer defines how we'll know if the solution works, before a line of code is written. 4. **Implementation:** A Feature Implementer writes the code to pass those tests. 5. **Quality Assurance:** A QA Engineer validates the whole thing against the original requirements. Before any of this happens, though, there's a critical pre-phase. The master orchestrator has a detailed conversation with the user to clarify the requirements. This isn't just about getting a yes or no; it's an exploration that often uncovers hidden assumptions. The goal is to turn a vague request into a concrete, documented plan. ## How it works in practice Let's return to that "track more page visits" request. My initial prompt was, "I want to track user visits to more pages. Currently, we only track when users go to the home page." A simple AI might have just started spitting out code. Instead, the master orchestrator analyzed the existing codebase and came back with questions. It had already figured out I only tracked one visit per session and laid out four possible interpretations of my request, from simply tracking more pages to adding deep engagement metrics. It recommended Option 1—tracking individual page navigations—and asked clarifying questions about API calls, privacy, and the admin dashboard. ![alt text](assets/coding-agent-team-0.png) This initial back-and-forth was transformative. My vague idea became a concrete plan. I decided to track every page navigation, make a single API call per page to avoid spamming the server, and enhance the admin dashboard. The orchestrator documented this in a file, `final-requirements.md`, complete with timestamps and unique IDs for each requirement. This document became the source of truth for the entire project. With the requirements locked in, the team got to work. The **Researcher** spent four minutes and used 14 tool calls to analyze my routing architecture and research best practices for the specific stack. The **Project Manager** then created Architecture Decision Records (ADRs) and detailed specifications. It broke the work down into route-level tracking, session management, and dashboard components, all tracing back to the IDs in the requirements file. Next, the **Test Case Designer** spent fourteen minutes and 35 tool calls creating a comprehensive suite of tests. There were unit tests for the tracking logic, integration tests for the analytics service, and end-to-end tests for user journeys. This felt like a lot of work upfront, but it was really just diligence. Only then did the **Feature Implementer** start writing code. It built the TypeScript interfaces, the tracking middleware, and the new dashboard components, with the explicit goal of making all the tests pass. ![alt text](assets/coding-agent-team-1.png) Finally, the **QA Engineer** validated the whole implementation. It checked not only that the code worked but that it correctly fulfilled the original requirements from `final-requirements.md`. Did it track *all* page visits? Did it avoid duplicate API calls? Did the dashboard show meaningful insights? This phase wasn't just about finding bugs; it was about ensuring I had built what I'd set out to build. ![alt text](assets/coding-agent-team-2.png) The result was a production-ready analytics system, complete with tests and documentation that explained not just what was built, but why. ## What I learned The difference was noticeable. I saw fewer post-deployment bugs, especially for complex features. The documentation became radically better because every decision was captured as it was made. And onboarding new engineers became easier because they could read the session logs and understand the thinking behind a feature. The "works on my machine" problem for complex setups virtually disappeared. But the biggest change wasn't a number on a chart. It was a feeling of predictability. Complex features no longer felt like a gamble. If you wanted to build something like this, the lessons I learned are straightforward. **First, think in terms of roles, not just prompts.** Start with three: a Researcher, a Planner, and an Implementer. You can add more specialized roles as you find you need them. **Second, make documentation the centerpiece of the workflow.** Every task should start with a timestamped directory. The structure I use looks like this: ```text docs/sessions/YYYY-MM-DD-HHMM/ ├── requirements/ ├── research/ ├── planning/ ├── test-cases/ └── implementation/ ``` The output of one agent in its directory becomes the input for the next. This creates an audit trail that is invaluable. Each phase ends by creating a `STATUS.md` file, which is a narrative of what was done, what decisions were made, and why, all linked back to the original requirements. It’s a quality gate, not just a checkbox. The most surprising thing is that this system feels less like operating a machine and more like managing a very efficient team. The documentation reads like a series of well-documented conversations and handoffs. ## Realistic expectations This workflow isn’t magic. It doesn't produce a perfect, finished feature in a single pass. What it does produce is a very strong first draft—maybe 50-70% of the way to the final solution. From there, a human developer needs to step in, assess what's missing, and perhaps run the process again on smaller, more targeted tasks. And maybe that's the right model. The goal isn't to replace human developers, but to give them a much better starting point. I've spent so much of my time on the scaffolding of software development—understanding requirements, setting up tests, writing boilerplate. The agent team automates much of that, leaving me to focus on the hard parts that require real judgment and creativity. It turns out that a simple request to track page visits led me to a new way of thinking about building software with AI. The answer wasn't a better AI, but a better process. By structuring the work like a human team, I didn't just get better code; I got a system that documents its own thinking. And in the long run, that might be the most valuable thing it builds.

Mem0 & Mem0-Graph breakdown

## Overview ### Introduction to Mem0 and the problems it solves Large Language Models (LLMs) are limited by fixed context windows, which restrict their ability to maintain consistency over long, multi-session dialogues. Without persistent memory, AI agents may forget user preferences, repeat questions, or contradict previously established facts, undermining user experience and trust. For example, an agent might recommend chicken to a user who previously stated they were vegetarian and dairy-free. Even with large context windows (e.g., GPT-4, Claude 3.7 Sonnet, Gemini), these improvements only delay the problem, as meaningful conversation histories eventually exceed any window size. Additionally, important information can be buried under irrelevant tokens, and attention mechanisms degrade over distant tokens. **Mem0** addresses these limitations with a scalable memory-centric architecture that dynamically extracts, consolidates, and retrieves salient information from ongoing conversations. This enables AI agents to build and maintain long-term memory, supporting stateful and contextually aware interactions that span days, weeks, or months. By integrating such memory mechanisms, Mem0 allows AI agents to maintain consistent personas, track evolving user preferences, and build upon prior exchanges—transforming AI from forgetful responders into reliable, long-term collaborators. Beyond conversation, memory mechanisms enhance agent performance in interactive environments, enabling anticipation of user needs, learning from mistakes, generalization across tasks, and improved decision-making. ### Key technical advances - **Two-Phase Memory Pipeline:** Mem0 processes each new message pair (user message and assistant response) in two phases: - **Extraction:** Uses both a conversation summary and a sequence of recent messages to provide context. An LLM-based extraction function identifies salient memories (candidate facts) for the knowledge base. - **Update:** Each candidate fact is compared to existing memories using vector similarity. An LLM determines whether to ADD, UPDATE, DELETE, or NOOP (no change) for each fact, ensuring consistency and avoiding redundancy. - **Graph-Based Memory Representation:** The Mem0g variant represents memories as a directed labeled graph, where: - **Nodes** represent entities (with types, embeddings, and metadata). - **Edges** represent relationships as triplets (source, relation, destination). - **Labels** assign semantic types to nodes. LLMs extract entities and relationships, and an update resolver manages conflicts and temporal reasoning. This structure supports advanced reasoning and multi-hop queries. - **Implicit Forgetting via Relevance Filtering:** Mem0 avoids context overload by selectively extracting and retrieving only relevant information, rather than processing entire conversation histories. This reduces computational overhead, latency, and token costs, while preventing the model from being burdened by irrelevant data. ### Component categories and responsibilities - **Extractor:** Identifies and extracts key facts from new message pairs, using both a conversation summary and recent messages. An LLM analyzes this context to produce candidate facts for the knowledge base. - **Updater:** Consolidates information and ensures memory consistency. For each candidate fact, it retrieves similar existing memories and uses an LLM to decide whether to ADD, UPDATE, DELETE, or NOOP. - **Retriever:** Accesses relevant information from the memory store. - For Mem0: Uses dense embeddings in a vector database for similarity search. - For Mem0g: Combines entity-centric graph traversal and semantic triplet matching for flexible retrieval. - **Memory Store:** Pluggable backend for persistent storage and vector-based indexing. - Mem0 supports a wide range of vector store providers (e.g., Qdrant, ChromaDB, PineconeDB, FAISS). - Mem0g primarily uses Neo4j and other graph databases, combining structural richness with semantic flexibility. ### Example use cases - **Personalized AI Assistants:** Remember user preferences and details across sessions for tailored assistance (e.g., dietary restrictions for dinner recommendations). - **Multi-Session Customer Support:** Maintain context across multiple interactions, enabling seamless and effective support over days or weeks. - **Complex Problem-Solving Agents:** Recall facts and constraints from long-running tasks, anticipate needs, learn from mistakes, and generalize knowledge for improved decision-making and long-term reasoning. - **Cross-Platform Memory Sync:** The [Mem0 Chrome Extension](https://github.com/mem0ai/mem0-chrome-extension) maintains and synchronizes memory context across different AI chat interfaces, ensuring consistent experiences regardless of the platform used. - **Conversational Memory Management:** The [OpenMemory MCP Server](https://mem0.ai/openmemory-mcp) manages and surfaces relevant memories during conversations, enabling AI systems to maintain contextual awareness across sessions. - **Ambient Intelligence Applications:** When deployed in ambient computing scenarios, Mem0 can power: - **Recommendation Engines:** Learn user preferences over time to provide increasingly personalized suggestions. - **Health Trackers:** Monitor patterns, behaviors, and health metrics across extended periods for comprehensive wellness insights. - **Procedural Memory for Automation:** Store and recall complex workflows and automation sequences, adapting to user habits. - **Interactive Storytelling:** Create rich, persistent narrative experiences in gaming (imagine AI Dungeon with deep, consistent world memory and character development). --- ## How it works Mem0 is a scalable, memory-centric architecture designed to overcome the fixed context window limitations of Large Language Models (LLMs) in maintaining long-term, multi-session consistency. It achieves this by dynamically extracting, consolidating, and retrieving salient information from conversations. The enhanced Mem0g variant leverages graph-based memory representations to capture complex relationships among conversational elements. ### Architecture overview LLMs typically "forget" information once it falls outside their context window, leading to issues like lost user preferences or contradictory responses. Mem0 addresses this by externalizing memory management through several core components: - **Extractor:** Identifies and captures key information from ongoing conversations. - **Updater:** Compares extracted information with existing memories to maintain consistency and avoid redundancy. - **Retriever:** Dynamically fetches relevant information from the memory store for new interactions. - **Memory Store:** Central repository for storing and organizing memories. Mem0 uses dense, text-based storage, while Mem0g represents memories as directed labeled graphs (entities as nodes, relationships as edges). This architecture mimics human cognition by selectively storing, consolidating, and retrieving important information, even as conversations exceed context window limits or lose thematic continuity. ![memory pipeline architecture](assets/mem0-vector-architecture.png) ![memory graph architecture](assets/mem0-graph-architecture.png) ### Request flow A typical interaction with a Mem0-powered AI agent follows a structured, incremental process across two main phases: extraction and update. 1. **User Message:** The user sends a message, initiating a new interaction. 2. **Memory Retrieval:** The agent retrieves relevant memories using the message as a query. - Mem0 uses two sources: a conversation summary (semantic overview of the history) and a sequence of recent messages (controlled by a recency window hyperparameter, e.g., last 10 messages). - Mem0g combines entity-centric graph traversal (identifying key entities and relationships) with semantic triplet matching (using dense embeddings to match relationship triplets). 3. **Context Construction:** Retrieved memories, the conversation summary, recent messages, and the new message are combined into a prompt for the LLM. 4. **LLM Response:** The LLM generates a response using the constructed context. 5. **Extraction Phase:** The conversation turn (user message + agent response) is sent to the Extractor, which uses an LLM to extract salient facts (candidate memories) from the exchange. - In Mem0g, this involves entity extraction and relationship generation to form triplets. 6. **Update Phase:** The Updater evaluates each candidate fact against existing memories. - Retrieves the top-k semantically similar memories using vector embeddings. - Presents these to an LLM via a function-calling interface ("tool call"). - The LLM decides to ADD, UPDATE, DELETE, or NOOP each fact. - In Mem0g, conflict detection and an LLM-based resolver handle relationship updates, supporting temporal reasoning by marking relationships as invalid rather than deleting them. This pipeline enables Mem0 to dynamically capture, organize, and retrieve information, allowing AI agents to maintain coherent, context-aware conversations over extended periods—closely resembling human communication patterns. ```mermaid graph TD subgraph Conversation Context direction LR A[Latest Exchange] B[Rolling Summary] C[Most Recent Messages] end subgraph "Phase 1: Extraction" direction TB D(LLM with FACT_RETRIEVAL_PROMPT) E[Salient Facts Extracted] end subgraph "Phase 2: Update" direction TB F[1.

Each memory object includes: - **Fact/Data:** The core content of the memory. - **Vector Embedding:** A dense vector capturing the semantic meaning of the memory, generated by an Embedder component. - **Metadata:** Contextual details such as a unique ID, hash, timestamps (`created_at`, `updated_at`), and identifiers like `user_id` and `agent_id`. For Mem0g, entities also have a type classification. - **Conversation Turn:** A complete exchange (user message and agent response), serving as the main source for fact extraction. Each turn is processed by the Extractor to identify new facts. - **Retrieved Context:** A curated set of relevant Memory Objects fetched to inform the LLM's current turn. This context combines a conversation summary and a sequence of recent messages, forming a comprehensive prompt for the LLM. ### Key algorithms Mem0 employs several algorithms throughout its memory management lifecycle: - **Salient Fact Extraction:** An LLM analyzes conversational text using a specialized prompt that includes the conversation summary, recent messages, and the current message pair. The Extractor identifies salient memories (candidate facts) for the knowledge base. In Mem0g, this involves: - Entity extraction (identifying key entities and types). - Relationship generation (deriving connections between entities as triplets), using tools like `EXTRACT_ENTITIES_TOOL` and `RELATIONS_TOOL`. - **Memory Consolidation:** The Updater maintains consistency and avoids redundancy: - Retrieves the top `s` semantically similar memories using vector embeddings. - Presents these and the new candidate fact to an LLM via a function-calling interface. - The LLM determines whether to **ADD**, **UPDATE**, **DELETE**, or **NOOP** each fact. - In Mem0g, conflict detection and an LLM-based resolver mark relationships as invalid (supporting temporal reasoning) rather than deleting them, using tools such as `ADD_MEMORY_TOOL_GRAPH`, `UPDATE_MEMORY_TOOL_GRAPH`, `DELETE_MEMORY_TOOL_GRAPH`, and `NOOP_TOOL`. - **Relevance-Based Retrieval:** Efficiently fetches the most pertinent information for the LLM's context window: - Uses vector similarity search (e.g., cosine similarity) to find the top-k relevant memories. - Mem0g combines entity-centric graph traversal with semantic triplet matching (encoding queries as dense vectors and matching against relationship triplets). - Supports various vector database providers (e.g., Qdrant, Chroma, Pinecone, FAISS, and others). ### Storage and memory management Mem0 features an abstracted storage layer and mechanisms for organizing conversational history: - **Vector Store Structure:** An abstracted `VectorStore` layer supports multiple vector databases, enabling flexible deployment. Memories are indexed by embeddings for efficient retrieval. The `VectorStoreBase` class defines standard operations: - `create_col`, `insert`, `search`, `update`, `delete`, `get`, `list_cols`, `delete_col`, `col_info`, `list`, `reset`. - **Conversation Chains:** Memories are logically associated with users or agents via metadata (`user_id`, `agent_id`), enabling: - Separation and retrieval of individual conversation histories. - Consistent personas and tracking of evolving preferences. - In Mem0g, graph nodes include metadata for precise querying and management, with temporal awareness to prioritize recent information. ## Technical challenges and solutions ### Stateless LLMs vs. stateful conversations Large Language Models (LLMs) are inherently stateless, limited by fixed context windows that cause them to "forget" information once it falls outside the window. This makes it difficult to maintain consistency and coherence across long, multi-session dialogues. **Mem0** addresses this by externalizing conversational state into a persistent memory layer. By dynamically extracting, consolidating, and retrieving salient information, Mem0 enables LLMs to recall past interactions, user preferences, and established facts across sessions. ### Memory redundancy and bloat Continuous fact extraction can lead to redundant or bloated memory stores. Mem0 mitigates this through its **Memory Consolidation (Update Phase)** algorithm. After extracting salient facts from a conversation turn, the Updater compares new facts against existing memories using vector similarity. An LLM, via a function-calling interface, determines the appropriate operation for each fact: - **ADD:** Insert genuinely new information. - **UPDATE:** Augment existing memories with more recent or detailed information (e.g., updating "User likes to play cricket" to "Loves to play cricket with friends"). - **DELETE:** Remove memories contradicted by new information. - **NOOP:** Ignore if the fact already exists or is irrelevant. This process prevents duplication and maintains a coherent, temporally consistent knowledge base. In Mem0g, conflict detection and an LLM-based resolver mark conflicting relationships as invalid, supporting temporal reasoning without deleting data. ### Maintaining contextual coherence To respond contextually, an AI agent needs both recent and relevant long-term information. Mem0 creates a **Retrieved Context** for each conversational turn by combining: - A conversation summary (semantic overview of the history). - A sequence of recent messages (e.g., last 10 messages). - The new message pair (user input and agent response). This dual-context approach, along with selective retrieval of relevant Memory Objects, ensures the LLM has both broad thematic understanding and specific recent details. Mem0g enhances this with entity-centric retrieval and semantic triplet matching, exploring relationships within the knowledge graph for richer context. ### Fixed token budget management LLMs have strict token limits, making it impractical to feed the entire conversation history. Mem0 addresses this by: - **Salient Fact Extraction:** Using LLMs to extract only the most important facts and preferences, resulting in concise, structured memories. - **Relevance-Based Retrieval:** Employing vector similarity search to retrieve only the top-k most relevant memories for each turn. This selective approach significantly reduces token consumption and latency, achieving substantial cost and performance improvements over full-context methods. ### Ensuring memory accuracy The quality of an agent's responses depends on memory accuracy. Mem0 leverages LLMs at critical stages: - **Extraction:** LLMs analyze conversation turns and convert them into structured facts, minimizing missed or misrepresented information. - **Consolidation:** LLMs resolve conflicts, augment existing memories, and avoid redundancy during the update phase. These LLM-driven processes reduce hallucinations and outdated information. Mem0's evaluation on the LOCOMO benchmark demonstrates higher factual accuracy compared to existing memory systems. ### Backend flexibility Production-ready AI agents require flexible storage solutions. Mem0 provides an abstracted **VectorStore** layer, defining standard operations (add, get, search, update, delete) implemented by various vector databases. Supported providers include Qdrant, Chroma, PGVector, Milvus, Upstash Vector, Azure AI Search, Pinecone, MongoDB, Redis, Elasticsearch, Vertex AI Vector Search, Supabase, Weaviate, FAISS, and Langchain. This modular design allows users to swap vector database backends without modifying Mem0's core logic, supporting diverse deployment needs. ## Clever tricks and tips we discovered - **Prioritizing Recent Information:** Mem0 focuses memory extraction on the most immediate and relevant conversational exchanges, operating on the assumption that new information is typically the most pertinent. Extraction is triggered upon ingestion of each new message pair (user message and assistant response), with additional context provided by a configurable window of recent messages (e.g., last 10). This approach efficiently captures evolving user needs and preferences. - **Dual Context Extraction:** To ensure comprehensive context, Mem0 combines two sources for memory extraction: - A **conversation summary** (semantic overview of the entire history), asynchronously generated and periodically refreshed to provide global thematic understanding. - A **sequence of recent messages** (e.g., last 10), offering granular temporal context and capturing details not yet consolidated into the summary. This dual-context prompt enables the LLM to extract salient memories while maintaining awareness of both broad themes and recent specifics. - **Proactive Fact Extraction:** Mem0 keeps its memory store consistently up-to-date by extracting and evaluating salient facts after every conversation turn. This continuous, proactive process ensures that the memory reflects the latest interactions, reducing the risk of stale or outdated information. - **Implicit Forgetting:** Rather than explicitly deleting old data, Mem0 "forgets" by selectively storing only the most salient facts and preferences. As new, more relevant information is extracted, older or less important details naturally become less likely to be retrieved. While DELETE operations exist for contradictions, the main mechanism is relevance-based retrieval—ensuring that only the most pertinent information is surfaced for each query. - **Switching to Graphs for Complexity:** Mem0 supports two memory architectures: - The base **Mem0** uses dense natural language memories in vector databases, excelling at rapid retrieval and efficient multi-hop reasoning with low latency and token cost. - For tasks requiring deeper relational understanding, **Mem0g** leverages graph-based memory, structuring memories as directed labeled graphs (entities as nodes, relationships as edges). This enables nuanced temporal and contextual reasoning, at the cost of moderate additional latency and token usage, making it ideal for complex, open-domain queries. ## What we would do differently & future improvements ### Memory persistence & auditing **Current State:** Mem0 implements memory persistence and auditing through its ADD, UPDATE, DELETE, and NOOP operations during the update phase. Each memory modification is logged with `old_memory`, `new_memory`, event type, and timestamps, creating an audit trail. In Mem0g, relationships can be marked as invalid (soft deletion) to preserve historical context for temporal reasoning. **Future Improvements:** While change logging exists, there is no explicit human-in-the-loop review or comprehensive versioning beyond the current fields. Future work could introduce interfaces for human oversight, allowing review and override of AI-generated memory updates. A more robust versioning system would enable easier rollback and comparison of memory states. Further, developing memory consolidation mechanisms inspired by human cognition could enhance auditing and versioning. ### Handling nuance **Current State:** Mem0 uses LLMs for memory extraction, providing contextual understanding and basic multilingual support by recording facts in the detected language of user input. **Future Improvements:** Current methods do not explicitly address advanced linguistic nuances such as sarcasm, idioms, or complex multilingual interpretations. Future enhancements would focus on improving extraction functions to better capture these subtleties, ensuring memories reflect user intent even in indirect or culturally specific expressions. ### Dynamic triggering **Current State:** Memory extraction is triggered by each new message pair, with a configurable recency window (e.g., last 10 messages). **Future Improvements:** The trigger mechanism is static. Future research could explore dynamic strategies, such as: - Detecting topic shifts to trigger extraction when conversations change direction. - Using information density to trigger extraction when significant new information appears. - Inferring user intent to prompt targeted memory updates. ### Formal benchmarking **Current State:** Mem0 includes a comprehensive evaluation framework, using the LOCOMO benchmark and LLM-as-a-Judge metrics to assess factual accuracy, relevance, and contextual appropriateness. Mem0 and Mem0g outperform existing systems, with Mem0g excelling in temporal reasoning. ![Benchmark latency](assets/mem0-benchmarck-latency.png) **Future Improvements:** Potential directions include: - Standardizing evaluation protocols with the broader AI community for long-term memory systems. - Developing adversarial tests to challenge the system’s robustness as memory size and complexity increase. - Extending benchmarks to new domains, such as procedural reasoning and multimodal interactions, to measure memory accuracy in diverse contexts.

customServers: 'AI-assisted server development with scaffolding'; configuration: '~/Documents/Cline/MCP directory'; naturalLanguage: 'Create tools through conversation ("add a tool that searches the web")'; } ``` ### API provider factory pattern Cline supports 33+ AI providers through a unified factory pattern with provider-specific optimizations: ```typescript // Multi-provider API factory class ApiHandlerFactory { static create( provider: string, config: ApiConfig, mode: 'plan' | 'act', ): ApiHandler { const modeConfig = mode === 'plan' ? config.planMode : config.actMode; switch (provider) { case 'anthropic': return new AnthropicHandler({ ...config, ...modeConfig }); case 'openai': return new OpenAiHandler({ ...config, ...modeConfig }); case 'qwen': return new QwenHandler({ ...config, ...modeConfig, contextBuffer: 0.85, }); case 'bedrock': return new BedrockHandler({ ...config, ...modeConfig }); //... other providers default: return new ClineProviderHandler(config); } } } ``` ### Stream processing architecture Cline implements sophisticated streaming for real-time AI interaction with race condition prevention: ```typescript // Stream processing with race condition prevention class StreamProcessor { private presentationLock = false; private pendingUpdates = false; async processStream(stream: AsyncGenerator) { for await (const chunk of stream) { switch (chunk.type) { case 'usage': this.trackTokenUsage(chunk); break; case 'reasoning': await this.streamReasoning(chunk.reasoning); break; case 'text': this.contentBlocks.push(...this.parseContent(chunk.text)); await this.presentContent(); break; case 'tool_call': await this.handleToolCall(chunk); break; } if (this.shouldAbort()) break; } } private async presentContent() { if (this.presentationLock) { this.pendingUpdates = true; return; } this.presentationLock = true; try { await this.renderContentBlocks(); if (this.pendingUpdates) { this.pendingUpdates = false; await this.presentContent(); } } finally { this.presentationLock = false; } } } ``` ```mermaid graph TB subgraph "Provider Layer" AnthropicProvider["AnthropicHandler"] BedrockProvider["AwsBedrockHandler"] ClineProvider["ClineHandler"] VertexProvider["VertexHandler"] OtherProviders["Other Providers..."] end subgraph "Stream processing Core" ApiStream["ApiStream

Cline implements a sophisticated multi-stage optimization system that dynamically adapts to different token pressure scenarios while preserving the most critical conversational context. **The Challenge**: AI models have finite context windows (ranging from 64K tokens for smaller models to 200K+ for larger ones), but development conversations can easily exceed these limits through: - Large file contents being read and discussed - Extensive conversation history across multiple development sessions - Tool execution results and code changes accumulating over time - Memory bank updates and project context information **The Solution**: Context optimization strategy that intelligently prioritizes content based on relevance, recency, and criticality: **Critical Context Preservation Rules**: - **System prompts**: Always preserved (defines AI behavior and capabilities) - **Memory bank content**: High priority (maintains project understanding) - **Recent tool results**: Critical for current task context - **User instructions**: Never truncated (maintains user intent) - **Error messages**: High priority (debugging context) - **File modifications**: Recent changes preserved over historical ones ```typescript // Context window management with intelligent truncation class ContextWindowManager { async optimizeContext( messages: Message[], api: ApiHandler, maxTokens: number, ) { // Stage 1: Remove redundant content const optimized = this.removeDuplicates(this.removeObsolete(messages)); const currentTokens = await this.calculateTokens(optimized, api); if (currentTokens <= maxTokens) return { messages: optimized, truncated: false }; // Stage 2: Intelligent truncation preserving critical context const strategy = this.selectStrategy(currentTokens / maxTokens); const truncated = this.applyTruncation(optimized, strategy); return { messages: truncated, truncated: true, strategy }; } private selectStrategy(pressure: number): TruncationStrategy { if (pressure > 2.0) return { type: 'aggressive', keepRatio: 0.25 }; if (pressure > 1.5) return { type: 'moderate', keepRatio: 0.5 }; return { type: 'conservative', keepRatio: 0.75 }; } } ``` ### File context tracking system The file context tracker intelligently manages which files are included in the AI's context through a sophisticated scoring algorithm that adapts to developer behavior patterns and project needs. This system ensures that the most relevant files are always available to the AI while staying within token budget constraints. **The Challenge**: Development projects can contain thousands of files, but AI context windows can only accommodate a limited subset. The system must dynamically determine which files are most relevant to the current development task without losing important project context. **Key Factors in File Selection**: - **Recency**: Files are tracked with `cline_read_date`, `cline_edit_date`, and `user_edit_date` timestamps - **Frequency**: Files frequently referenced in conversations get boosted scores - **Modification status**: Recently modified files are prioritized through the `recentlyModifiedFiles` set - **File type awareness**: The system tracks different operation types (`read_tool`, `user_edited`, `cline_edited`, `file_mentioned`) ```mermaid flowchart TD subgraph "File Context Intelligence System" FileWatchers[👁️ VS Code File Watchers

Context window management **Challenge**: Long conversations and large codebases exceed AI model token limits, causing API failures and loss of conversational context. Different models have varying context windows (64K for DeepSeek, 200K for Claude), making it difficult to maintain consistent behavior across providers. **Innovation**: Intelligent multi-stage context optimization that preserves critical information while staying within limits: - Remove redundant content (duplicate file reads, obsolete information) - Apply adaptive truncation strategies (25%, 50%, or 75% retention based on pressure) - Preserve critical context (system prompts, original tasks, recent tool results) - Provider-aware buffers with different safety margins (27K-40K token buffers) ### 2. Safe autonomous operation with Git shadow versioning **Challenge**: Enabling AI to perform autonomous coding actions while preventing system damage, maintaining user control, and providing reliable rollback capabilities. Users need confidence that they can safely allow AI to modify their codebase. **Innovation**: Git shadow versioning system that creates invisible rollback points: ```typescript // Git shadow versioning for safe rollbacks class ShadowGitManager { private shadowNamespace = 'refs/cline/shadow'; async createShadowCommit( changes: FileChange[], taskId: string, ): Promise { const shadowRef = `${this.shadowNamespace}/${taskId}`; const commitHash = await this.git.commit(changes, { ref: shadowRef, message: `Cline checkpoint: ${new Date().toISOString()}`, author: { name: 'Cline Assistant', email: 'cline@ai-assistant.dev' }, }); await this.storeCheckpointMetadata(commitHash, { taskId, changes, userBranch: await this.git.getCurrentBranch(), }); return commitHash; } async rollbackToCheckpoint(checkpointHash: string): Promise { const metadata = await this.getCheckpointMetadata(checkpointHash); await this.git.checkoutFiles(checkpointHash, { force: true }); // Clean up created files without affecting user's Git history } } ``` ### 3. Real-time streaming with tool execution **Challenge**: Coordinating streaming AI responses with tool execution requests while maintaining UI responsiveness. Race conditions can occur when multiple tool calls happen simultaneously, and users need real-time feedback during long-running operations. **Innovation**: Sophisticated streaming architecture with presentation locking and incremental diff streaming: ```typescript // File diff streaming with VSCode integration class VscodeDiffViewProvider extends DiffViewProvider { private activeDiffEditor?: vscode.TextEditor; private fadedOverlayController?: DecorationController; private activeLineController?: DecorationController; override async openDiffEditor(): Promise { const uri = vscode.Uri.file(this.absolutePath); const fileName = path.basename(uri.fsPath); const fileExists = this.editType === 'modify'; // Create virtual document for original content using custom URI scheme this.activeDiffEditor = await new Promise( (resolve, reject) => { const disposable = vscode.window.onDidChangeActiveTextEditor( (editor) => { if ( editor && arePathsEqual(editor.document.uri.fsPath, uri.fsPath) ) { disposable.dispose(); resolve(editor); } }, ); // Execute diff command with virtual URI for original content vscode.commands.executeCommand( 'vscode.diff', vscode.Uri.parse(`${DIFF_VIEW_URI_SCHEME}:${fileName}`).with({ query: Buffer.from(this.originalContent ?? '').toString('base64'), }), uri, `${fileName}: ${ fileExists ? "Original ↔ Cline's Changes" : 'New File' } (Editable)`, { preserveFocus: true }, ); }, ); // Set up real-time visual feedback controllers this.fadedOverlayController = new DecorationController( 'fadedOverlay', this.activeDiffEditor, ); this.activeLineController = new DecorationController( 'activeLine', this.activeDiffEditor, ); this.fadedOverlayController.addLines( 0, this.activeDiffEditor.document.lineCount, ); } // Stream incremental updates with visual feedback override async replaceText( content: string, rangeToReplace: { startLine: number; endLine: number }, currentLine: number | undefined, ): Promise { const document = this.activeDiffEditor?.document; const edit = new vscode.WorkspaceEdit(); const range = new vscode.Range( rangeToReplace.startLine, 0, rangeToReplace.endLine, 0, ); edit.replace(document.uri, range, content); await vscode.workspace.applyEdit(edit); // Update visual indicators for streaming progress if (currentLine !== undefined) { this.activeLineController?.setActiveLine(currentLine); this.fadedOverlayController?.updateOverlayAfterLine( currentLine, document.lineCount, ); } } } ``` The system integrates with VS Code's native diff viewer through `extension.ts` a custom text document content provider that serves virtual documents for the "before" state, while streaming updates are applied to the actual file in real-time. The streaming JSON replacement system for advanced models handles incremental updates through `ToolExecutor.ts` callbacks that update the diff view as content arrives, enabling users to see file changes being applied character by character during AI generation. This architecture prevents race conditions through `DiffViewProvider.ts` presentation locking mechanisms and provides immediate visual feedback through decoration controllers that highlight the currently streaming content sections. ### 4. XML tool calling innovation **Challenge**: Most AI models (especially Google Gemini, Alibaba Qwen, and local models) lack native JSON tool calling support, limiting their participation in the agent ecosystem. Traditional approaches require separate training for structured output, creating barriers for model adoption. **Innovation**: XML-based tool calling that democratizes agent capabilities across all models: ```typescript // XML tool calling parser that works with any model class XmlToolCallParser { parseToolCalls(response: string): ToolCall[] { const toolCallRegex = /\s*\s*(.*?)\s*<\/invoke>\s*<\/tool_call>/gs; const calls: ToolCall[] = []; let match; while ((match = toolCallRegex.exec(response)) !== null) { const [, toolName, parametersXml] = match; const parameters = this.parseXmlParameters(parametersXml); calls.push({ name: toolName, parameters }); } return calls; } private parseXmlParameters(xml: string): Record { const paramRegex = /(.*?)<\/parameter>/gs; const params: Record = {}; let match; while ((match = paramRegex.exec(xml)) !== null) { params[match[1]] = match[2].trim(); } return params; } } ``` This approach enables: - **Universal model support**: Any model that can generate text can participate in agent workflows - **Training-free integration**: No additional fine-tuning required for tool calling capabilities - **Adoption by major engineering teams**: Google and Alibaba engineers use Cline specifically for this XML tool calling capability - **Graceful degradation**: Falls back seamlessly when native JSON tool calling isn't available ### 5. Generative streaming UI **Challenge**: Traditional AI interfaces provide static responses, losing the dynamic nature of tool execution. Users need real-time feedback for long-running operations like file editing, command execution, and browser automation. **Innovation**: XML tool calling serves as semantic labels for streaming generative UI components: ```typescript // Generative UI streaming with XML-driven components class GenerativeUIStreamer { async streamToolExecution(toolCall: ToolCall): Promise { const componentLabel = ``; await this.ui.streamComponent(componentLabel); switch (toolCall.name) { case 'edit_file': await this.streamFileDiff(toolCall.parameters); break; case 'execute_command': await this.streamTerminalOutput(toolCall.parameters); break; case 'browser_action': await this.streamBrowserInteraction(toolCall.parameters); break; } await this.ui.streamComponent( ``, ); } private async streamFileDiff(params: any): Promise { // Stream diff visualization as it's being generated const diffStream = this.generateDiff(params.file_path, params.new_content); for await (const chunk of diffStream) { await this.ui.updateComponent('file-diff', chunk); } } } ``` This approach differs from CLI tools or simple chat interfaces by providing: - **Real-time tool visualization**: See file diffs being generated line by line - **Interactive browser sessions**: Watch Cline navigate web pages with visual feedback - **Streaming command output**: Terminal interactions appear as they execute - **Progressive disclosure**: Complex operations break down into understandable steps ### 6. Multi-provider API integration **Challenge**: Supporting 33+ AI providers with different APIs, authentication methods, capabilities, and quirks. Each provider has unique token counting, error handling, streaming formats, and feature support. **Innovation**: Unified API handler factory with provider-specific optimizations and graceful feature degradation: - Factory pattern with single interface for all providers - Mode-aware configuration (Plan vs Act mode model selection) - Provider-specific handling for tokenization, context buffers, and error recovery - Feature detection with graceful degradation when capabilities aren't supported - Unified streaming interface despite different provider implementations ### 7. Dual-mode architecture **Challenge**: Balancing comprehensive analysis with efficient execution. Different types of work require different AI behaviors, models, and tool sets. **Innovation**: Separate Plan and Act modes with optimized configurations and seamless mode switching: ```typescript // Dual-mode architecture with mode-specific behavior interface ModeConfig { plan: { models: ['claude-opus', 'gpt-4']; tools: ['read', 'search']; focus: 'analysis'; }; act: { models: ['claude-sonnet', 'gpt-4-turbo']; tools: ['write', 'edit', 'bash']; focus: 'execution'; }; } class ModeManager { async switchMode(newMode: 'plan' | 'act'): Promise { await this.createModeTransitionCheckpoint(); this.currentMode = newMode; await this.updateSystemConfiguration(); await this.notifyModeChange(newMode); } getOptimalModel(mode: 'plan' | 'act', complexity: number): string { const models = ModeConfig[mode].models; return complexity > 0.7 ? models[0] : models[1]; // Capability-based selection } } ``` The system provides distinct behavioral modes through system prompt differentiation, where Plan mode focuses on information gathering and strategy development using the `plan_mode_respond` tool, while Act mode provides access to all execution tools except planning-specific ones. ### 8. Intelligent file context management **Challenge**: Determining which files to include in AI context from large codebases while staying within token limits. Need to balance relevance, recency, and importance while adapting to user behavior patterns. **Innovation**: Multi-factor file scoring system with dynamic context budgeting: - Combine recency, access frequency, file type, and user modifications into importance scores - Dynamic context budgeting that allocates tokens based on file importance - Real-time file monitoring that distinguishes between user and AI modifications - Adaptive learning that adjusts scores based on user interaction patterns - Context-aware inclusion that prioritizes files relevant to current task ### 9. Client-side architecture and security design **Challenge**: Ensuring data privacy and security while maintaining full functionality in an AI coding assistant. Users need confidence that their code and proprietary information remain secure while enabling powerful AI capabilities. **Innovation**: Complete client-side processing with zero server-side components: **Core Architecture Components:** 1. **Extension entry** (`src/extension.ts`): Main extension entry point 2. **WebviewProvider** (`src/core/webview/index.ts`): Manages webview lifecycle and communication 3. **Controller** (`src/core/controller/index.ts`): Handles state and task management 4. **Task** (`src/core/task/index.ts`): Executes API requests and tool operations 5. **React frontend** (`webview-ui/src/App.tsx`): React-based webview interface **Direct API Architecture**: User input → React Webview → Controller → Task Manager → Direct Provider API → Tool Execution → Human Approval → Memory Bank Update → UI Response **Security Design**: All processing occurs client-side with direct cloud provider API connections. No code is sent to central servers, ensuring complete data privacy. ### 10. Multi-layered storage and state management **Challenge**: Efficiently managing different types of data (user preferences, conversation history, API credentials, project context) while working within VS Code's extension storage constraints and ensuring data persistence across sessions. **Innovation**: Multi-layered storage architecture designed for VS Code extension requirements: ```typescript // Multi-layered storage system interface ClineStorage { global: { location: 'VS Code globalState'; contains: 'user_preferences, api_keys'; }; workspace: { location: 'VS Code workspaceState'; contains: 'task_history, active_sessions'; }; secrets: { location: 'VS Code secretStorage'; contains: 'api_credentials' }; files: { location: 'workspace_files'; contains: 'configuration, memory_bank'; }; } ``` **Configuration Management:** - **`.clinerules`**: Project-specific configuration stored in repository - **`.clineignore`**: Specifies files/directories Cline should not access - **`cline_mcp_settings.json`**: Central storage for MCP server configurations - **`~/Documents/Cline/MCP`**: Directory for custom MCP servers **Memory Bank Integration**: Structured context management using hierarchical markdown files that maintain project understanding across development sessions. ``` projectbrief.md (foundation) → ├── productContext.md (project purpose) ├── systemPatterns.md (architecture) ├── techContext.md (technologies) └── activeContext.md (current focus) → progress.md (status) ``` ## UI/UX patterns and design innovation ### Streaming user interface and real-time feedback **Challenge**: Providing immediate visual feedback during AI response generation and tool execution while preventing race conditions and maintaining UI responsiveness. **Innovation**: Generative streaming UI that dynamically creates interface components based on AI actions: ```mermaid sequenceDiagram participant User participant UI as "React Webview" participant SP as "Stream Processor" participant Lock as "Presentation Lock" participant Tools as "Tool Executor" User->>UI: Initiates request UI->>SP: Start streaming process loop Streaming Response SP->>SP: Process chunk (reasoning/text/tool_call) alt Reasoning Chunk SP->>UI: 💭 Stream reasoning display UI->>User: Show AI thought process else Text Chunk SP->>Lock: Request presentation alt Lock Available Lock->>UI: 📝 Stream text content UI->>User: Character-by-character display else Lock Busy Lock->>Lock: Queue pending updates end else Tool Call Chunk SP->>Tools: Execute tool operation Tools->>UI: 📊 Stream tool execution UI UI->>User: Real-time progress feedback end end ``` **Key UX Patterns**: - **Character-by-character streaming**: Real-time AI response display with typing effect - **Progressive disclosure**: Complex operations broken into understandable steps - **Tool execution visualization**: See file diffs, command outputs, browser actions as they happen - **Reasoning display**: Show AI thought process transparently ### Dual-mode interface and behavioral adaptation **Challenge**: Optimizing user interface and interaction patterns for different types of development work (analysis vs. implementation) while maintaining workflow continuity. **Innovation**: Mode-specific UI adaptation that fundamentally changes interface behavior: ```typescript // Mode-specific interface configuration interface ModeUIConfig { plan: { tools: ['read_file', 'list_files', 'search_files']; behavior: 'analysis_focused'; approvals: 'minimal'; visualization: 'read_only'; }; act: { tools: ['write_file', 'edit_file', 'execute_command', 'browser_action']; behavior: 'execution_focused'; approvals: 'comprehensive'; visualization: 'diff_streaming'; }; } class ModeManager { async switchMode(newMode: 'plan' | 'act'): Promise { await this.createModeTransitionCheckpoint(); await this.updateUIConfiguration(newMode); await this.notifyModeChange(newMode); } } ``` **Plan Mode UI Features**: - Read-only interface emphasis - Information gathering tools prominent - Strategy development workspace - Safe exploration without modification risk **Act Mode UI Features**: - Execution tools prominently displayed - Real-time diff streaming - Comprehensive approval dialogs - Git checkpoint creation indicators ### Human-in-the-loop approval workflow design **Challenge**: Creating approval interfaces that maintain user control without disrupting development flow, balancing safety with efficiency. **Innovation**: Context-aware approval system with graduated risk assessment: ```mermaid flowchart TD subgraph "Approval Workflow UX" Action[🤖 AI Requests Action] RiskAssess{🎯 Risk Assessment} LowRisk[File read, search] MedRisk[File modification] HighRisk[Terminal commands, deletions] AutoApprove[✅ Auto-approve

The system operates beyond simple command execution, engaging in software development processes while maintaining safety mechanisms and user control through sophisticated visual feedback and interaction patterns. **Workspace Snapshots:** Cline creates workspace snapshots for rollback functionality: ```typescript // Workspace snapshot system interface WorkspaceSnapshot { id: string; timestamp: string; taskId: string; fileStates: Map; memoryBankState: MemoryBankSnapshot; diffSummary: { filesChanged: number; linesAdded: number; linesRemoved: number; }; } // Memory bank file purposes interface MemoryBankFiles { projectbrief: 'Foundation document shaping all other files'; productContext: 'Project existence rationale and functionality'; activeContext: 'Current work focus and recent changes'; systemPatterns: 'System architecture and technical decisions'; techContext: 'Technologies, frameworks, and development setup'; progress: 'Project status, completed work, and known issues'; } ``` ### Token and cost tracking **Challenge**: Providing transparency and control over AI API costs while maintaining seamless user experience. Users need visibility into token usage patterns and cost implications of their development workflows. **Innovation**: Comprehensive cost tracking with real-time monitoring and budget management: ```typescript // Token tracking with budget management interface TokenTracker { currentSession: { inputTokens: number; outputTokens: number; totalCost: number; }; providerStats: Map; budgetControl: { dailyLimit: number; currentSpend: number; warningThresholds: [0.8, 0.9]; }; optimization: { enableCaching: boolean; preferCheaperModels: boolean }; } ``` ### Mode-specific system prompts and behavioral differentiation **Challenge**: Optimizing AI behavior for different types of development work. Analysis and planning require different approaches than implementation and execution, but traditional AI assistants use the same behavioral patterns for all tasks. **Innovation**: Sophisticated, mode-specific system prompts that fundamentally change AI behavior: ```typescript // Mode-specific system prompts const SYSTEM_PROMPTS = { plan: `You are Cline in PLAN mode. Focus on analysis and planning: 1. Analyze user requests and project context 2. Ask clarifying questions when needed 3. Break down tasks into actionable steps 4. Identify challenges and dependencies 5. Create detailed plans for user approval Tools: read_file, list_files, search_files Approach: Understand first, then plan thoroughly.`, act: `You are Cline in ACT mode. Focus on implementation: 1. Execute approved plans step by step 2. Make concrete file changes and run commands 3. Test and validate changes 4. Create checkpoints before major changes 5. Request approval for destructive operations Tools: write_file, edit_file, execute_command, browser_action Principle: Safety first, then execution.`, shared: `Core principles: Be methodical, explain reasoning, follow best practices, ask for clarification, prioritize quality, respect existing patterns.`, }; ``` **Behavioral Differentiation**: Plan mode focuses on information gathering and strategy development using the `plan_mode_respond` tool, while Act mode provides access to all execution tools except planning-specific ones. ### State storage implementation and persistence **Challenge**: Reliably persisting complex application state across VS Code sessions while working within extension storage limitations and ensuring data integrity. **Innovation**: VS Code's native storage APIs with JSON serialization optimization: ```typescript // VSCode state management with JSON serialization class VSCodeStateManager { constructor(private context: vscode.ExtensionContext) {} async setGlobalState(key: string, value: T): Promise { await this.context.globalState.update(`cline.${key}`, value); } getGlobalState(key: string): T | undefined { return this.context.globalState.get(`cline.${key}`); } async setWorkspaceState(key: string, value: T): Promise { await this.context.workspaceState.update(`cline.${key}`, value); } getWorkspaceState(key: string): T | undefined { return this.context.workspaceState.get(`cline.${key}`); } async storeSecret(key: string, value: string): Promise { await this.context.secrets.store(`cline.${key}`, value); } async saveCompleteState(state: ClineState): Promise { await Promise.all([ this.setGlobalState('settings', state.settings), this.setGlobalState('tokenUsage', state.tokenUsage), this.setWorkspaceState('tasks', state.tasks), this.setWorkspaceState('conversations', state.conversations), ]); } } ``` ## Architectural improvements Based on analysis of the current implementation, here are key areas for architectural enhancement: ### 1. Simplified event-driven architecture - **Current**: Complex Controller → Task → Stream architecture with multiple layers - **Better**: Direct event-driven architecture with clear separation of concerns - **Benefits**: Reduced complexity, improved debugging, easier testing ### 2. Unified state management - **Current**: Dual-layer state (VSCode storage + React context) with complex synchronization - **Better**: Single source of truth with reactive updates (Redux/Zustand pattern) - **Benefits**: Eliminates race conditions, simpler state flow, better debugging ### 3. Plugin-based tool system - **Current**: Monolithic tool definitions with hardcoded schemas - **Better**: Dynamic plugin architecture with runtime registration - **Benefits**: Better extensibility, easier testing, community contributions ### 4. Vector-based context management - **Current**: Token-based truncation with optimization phases - **Better**: Semantic embeddings with importance scoring - **Benefits**: Preserves semantic context better, more predictable behavior ### 5. Risk-based safety system - **Current**: Binary approval gates with auto-approval settings - **Better**: Graduated risk assessment with granular permissions - **Benefits**: More nuanced control, better user experience, adaptive safety ```typescript // Improved architecture patterns interface ImprovedToolSystem { plugins: Map; registerTool(plugin: ToolPlugin): void; executeTool(name: string, params: unknown): Promise; getRiskLevel(name: string, params: unknown): RiskLevel; } interface SemanticContextManager { embeddings: Map; scoreImportance(message: Message): number; preserveSemanticClusters(messages: Message[]): Message[]; } interface GranularSafetySystem { riskAssessment: (action: Action) => RiskScore; permissionMatrix: Map; requestPermission(action: Action): Promise; } ``` This architecture provides a comprehensive foundation for an AI coding assistant that balances autonomy with safety, performance with reliability, and flexibility with maintainability.

Ax framework breakdown

![](assets/ax-framework-cheatsheet.png) ## Overview ### TL;DR Ax is the essential toolkit you wish to have in the new emerging trend of context engineering because it frees you from all the hassles of prompt engineering and enable you to focus more on your business domain logic. You might think it looks wizardry and PhD-level kind of things but at the end of the day it's just string templates. - **Template literal signatures**: Structured input/output, no more `"please output with JSON my life depends on it please 🙏"` shenanigans - **Fluent workflow engine**: Define workflows with declarative fluent API - **Advanced optimization**: Make your LLM smarter by literally teaching it, using the teacher-student pattern (no cap) Ax brings DSPy’s signature and optimization to TypeScript. Less prompt maneuver, more context engineering. ### You lost me at DSPy, wtf is that? Let's break it down, **D**eclarative **S**elf-improving **Py**thon: - Declarative: refers to the signature pattern - Self-improving: refers to the optimization flow where it learns by your examples - Python: quite self-explanatory ![](https://github.com/user-attachments/assets/059865cd-dfc3-4db1-9e04-7e9fc55a1f90) Ax is the faithful port of DSPy, preserving the core concepts. ### Problems it fixed LLM dev in TypeScript used to suck: - **No type safety**: Find out at runtime your LLM output is garbage - **Manual workflows**: Wire up multi-step operations by hand like a caveman - **Bad prompts**: Different prompt works with different model, tweaking your prompt to work correctly is even harder than asking your girl what to eat - **Vendor lock-in**: Switch providers? Rewrite everything. Fun. ### This sounds too good to be true, what's the catch? Compared to other frameworks/libraries like Mastra, VoltAgent or even the original DSPy itself: - Maturity: obviously because TypeScript is not the de-factor language of choice in the ML world, community adoption is still small. As a result, documentation is not as rich as others - Usecase: Ax takes the doubling down approach on conversational agents, it's no coincidence that most of the examples are just chatbots. So unless you want to omega-optimize your agent to provide 100/10 answers otherwise it's quite overkill ### The three foundational pillars - 🏛️ **Ax Signature (`AxSignature`)**: The most primitive unit of Ax, used in everywhere else - 🏛️ **Ax Flow (`AxFlow`)**: Fluent API with nodes that can be defined using Signatures -> Declarative workflows - 🏛️ **Ax Optimizer (`AxBaseOptimizer`, `AxBootstrapFewShot`, `AxMiPRO`)**: Help reduce time, cost of using smaller model when optimized ### The possibilities that Ax unlocks for you #### Wall-of-prompt-be-gone abracadabra Look mom, no prompts ```typescript import { AxAI, ax } from '@ax-llm/ax'; const textToSummarize = ` The technological singularity—or simply the singularity[1]—is a hypothetical future point in time at which technological growth becomes uncontrollable and irreversible, resulting in unforeseeable changes to human civilization.[2][3] ...`; const ai = new AxAI({ name: 'openai', apiKey: process.env.OPENAI_APIKEY as string, }); // no prompt, just input and output (*cough* context *cough*) const gen = ax`textToSummarize -> textType:class "note, email, reminder", shortSummary "summarize in 5 to 10 words"`; const res = await gen.forward(ai, { textToSummarize }); console.log('>', res); ``` #### Agent Smith would be proud Connect agents together, and they intercommunicate solely on signature (\*cough\* again context engineering \*cough\*) Look mom still no prompts ```typescript const researcher = new AxAgent({ name: 'researcher', description: 'Researcher agent', signature: `physicsQuestion "physics questions" -> answer "reply in bullet points"`, }); const summarizer = new AxAgent({ name: 'summarizer', description: 'Summarizer agent', signature: `text "text so summarize" -> shortSummary "summarize in 5 to 10 words"`, }); const agent = new AxAgent({ name: 'agent', description: 'A an agent to research complex topics', signature: `question -> answer`, agents: [researcher, summarizer], }); agent.forward(ai, { questions: 'How many atoms are there in the universe' }); ``` #### Make o4-mini as smart as o4? Hold my beer You token cost will go up, but isn't it always the case when it comes to education 🤷🏻‍♂️? ```typescript import { AxAI, AxChainOfThought, AxMiPRO } from '@ax-llm/ax'; // 1. Setup your AI service const ai = new AxAI({ name: 'openai', config: { model: AxOpenAIModel.O4Mini, }, apiKey: process.env.OPENAI_API_KEY, }); // 2. Create your program const program = new AxChainOfThought(`input -> output`); // 3. Configure the optimizer const optimizer = new AxMiPRO({ studentAI: ai, examples: trainingData, // Your training examples options: { numTrials: 20, // Number of configurations to try verbose: true, }, }); // 4. Define your evaluation metric // this is where the teaching happens const metricFn = ({ prediction, example }) => { return prediction.output === example.output; }; // 5. Run the optimization const result = await optimizer.compile(program, metricFn, { valset: validationData, // Optional validation set auto: 'medium', // Optimization level }); // 6. Use the optimized program const result = await optimizedProgram.forward(ai, { input: 'test input' }); ``` Hopefully by now you're intrigued in what Ax has to offer, read on to if you are ## How it works ### Architecture overview ```mermaid graph TD DEV[Developer Code] TL[Template Literals ax] SIG[AxSignature System] FLOW[AxFlow Engine] OPT[Optimizer Engine] AI[Multi-Provider AI Layer] DEV --> TL TL --> SIG SIG --> FLOW FLOW --> OPT SIG --> AI FLOW --> AI OPT --> AI subgraph "Type System" TS[TypeScript Compiler] RT[Runtime Validation] TL --> TS SIG --> RT end subgraph "Execution Engine" PAR[Parallel Planner] DEP[Dependency Analyzer] EXEC[Step Executor] FLOW --> PAR PAR --> DEP DEP --> EXEC end subgraph "Optimization Layer" BS[Bootstrap FewShot] MIPRO[MiPRO v2] BAY[Bayesian Optimization] OPT --> BS OPT --> MIPRO MIPRO --> BAY end ``` ### Request flow ```mermaid sequenceDiagram participant Dev as Developer participant TL as Template Literal participant Sig as Signature Parser participant Flow as Flow Engine participant Dep as Dependency Analyzer participant AI as AI Provider participant Optimizer as Optimizer Note over Dev,Optimizer: Signature Creation Dev->>TL: ax`userInput:string -> result:string` TL->>Sig: Parse template with field builders Sig->>Sig: Validate field names & types Sig->>Dev: Return typed AxGen instance Note over Dev,Optimizer: Flow Execution Dev->>Flow: .node().execute().map() Flow->>Dep: Analyze dependencies Dep->>Flow: Return execution plan Flow->>AI: Execute steps (parallel where possible) AI->>Flow: Return results Flow->>Dev: Type-safe results Note over Dev,Optimizer: Optimization Dev->>Optimizer: compile(program, metric) Optimizer->>AI: Generate instruction candidates Optimizer->>AI: Bootstrap few-shot examples Optimizer->>Optimizer: Bayesian parameter search Optimizer->>Dev: Optimized program + stats ``` ### Data structures and algorithms #### Signature system (Pillar #1) ![](./assets/ax_signature.png) ##### AxSignature: The core type definition ```typescript class AxSignature { private inputFields: AxIField[]; private outputFields: AxIField[]; private sigHash: string; private validatedAtHash?: string; // Template literal parsing with field builder support constructor(signature: string | TemplateStringsArray | AxSignatureConfig) { if (typeof signature === 'string') { const parsed = parseSignature(signature); this.inputFields = parsed.inputs.map(this.parseParsedField); this.outputFields = parsed.outputs.map(this.parseParsedField); } this.validateSignatureConsistency(); [this.sigHash, this.sigString] = this.updateHash(); } } ``` ##### Field builder system ```typescript export const f = { string: (desc?: string): AxFieldType => ({ type: 'string', description: desc, }), class: (options: readonly string[], desc?: string): AxFieldType => ({ type: 'class', options, description: desc, }), array: ( baseType: T, ): T & { readonly isArray: true } => ({ ...baseType, isArray: true, }), optional: ( baseType: T, ): T & { readonly isOptional: true } => ({ ...baseType, isOptional: true, }), // Multi-modal types image: (desc?: string): AxFieldType => ({ type: 'image', description: desc }), file: (desc?: string): AxFieldType => ({ type: 'file', description: desc }), url: (desc?: string): AxFieldType => ({ type: 'url', description: desc }), }; ``` - **Time complexity**: O(1) for field creation, O(n) for signature validation where n = number of fields - **Space complexity**: O(f) where f = total number of fields across all signatures - **Validation performance**: Cached validation using SHA-256 hashing to avoid re-validation ##### Extract and validate response ```typescript export const streamingExtractFinalValue = ( sig: Readonly, values: Record, // eslint-disable-next-line functional/prefer-immutable-types xstate: extractionState, content: string, strictMode = false ) => { if (xstate.currField) { const val = content.substring(xstate.s).trim(); const parsedValue = validateAndParseFieldValue(xstate.currField, val); if (parsedValue !== undefined) { values[xstate.currField.name] = parsedValue; } } // In strict mode, if we have content but no fields were extracted and no current field, // this means field prefixes were missing when they should have been present if (strictMode && !xstate.currField && xstate.extractedFields.length === 0) { const trimmedContent = content.trim(); if (trimmedContent) { // Find the first required field to report in the error const outputFields = sig.getOutputFields(); const firstRequiredField = outputFields.find( (field) => !field.isOptional ); if (firstRequiredField) { throw new ValidationError({ message: "Expected field not found", fields: [firstRequiredField], }); } // If only optional fields exist, ignore unprefixed content in strict mode } } // Check for optional fields that might have been missed by streaming parser parseOptionalFieldsFromFullContent(sig, values, content); // Check all previous required fields before processing current field checkMissingRequiredFields(xstate, values, sig.getOutputFields()); }; ``` #### Flow execution engine (Pillar #2) ##### Dynamic signature inference algorithm ```typescript private inferSignatureFromFlow(): AxSignature { const executionPlan = this.executionPlanner.getExecutionPlan(); const allProducedFields = new Set(); const allConsumedFields = new Set(); // Analyze execution plan for data flow for (const step of executionPlan.steps) { step.produces.forEach(field => allProducedFields.add(field)); step.dependencies.forEach(field => allConsumedFields.add(field)); } // Input fields = consumed but not produced const inputFields = [...allConsumedFields].filter(f => !allProducedFields.has(f)); // Output fields = produced but not consumed (special handling for final operations) const lastStep = executionPlan.steps[executionPlan.steps.length - 1]; let outputFields: string[]; if (lastStep && (lastStep.type === 'map' || lastStep.type === 'merge')) { outputFields = lastStep.produces.filter(f => !f.startsWith('_')); } else { outputFields = [...allProducedFields].filter(f => { return !executionPlan.steps.some(step => step.dependencies.includes(f)); }); } return this.buildSignatureFromFields(inputFields, outputFields); } ``` ##### Parallel execution planning ```typescript class AxFlowExecutionPlanner { createOptimizedExecution(batchSize: number): AxFlowStepFunction[] { const groups = this.identifyParallelGroups(); const optimizedSteps: AxFlowStepFunction[] = []; for (const group of groups) { if (group.steps.length === 1) { optimizedSteps.push(group.steps[0]!); } else { // Create parallel execution wrapper const parallelStep = async (state: AxFlowState, context: any) => { const results = await processBatches( group.steps, async (step, _index) => await step(state, context), batchSize, ); // Merge results maintaining execution order return results.reduce( (merged, result) => ({ ...merged, ...result }), state, ); }; optimizedSteps.push(parallelStep); } } return optimizedSteps; } private identifyParallelGroups(): AxFlowParallelGroup[] { const dependencies = this.analyzeDependencies(); const groups: AxFlowParallelGroup[] = []; const processed = new Set(); for (let i = 0; i < this.steps.length; i++) { if (processed.has(i)) continue; const parallelSteps = [this.steps[i]!]; processed.add(i); // Find steps that can run in parallel (no dependencies between them) for (let j = i + 1; j < this.steps.length; j++) { if (processed.has(j)) continue; const canRunInParallel = !this.hasDependency(dependencies, i, j) && !this.hasDependency(dependencies, j, i); if (canRunInParallel) { parallelSteps.push(this.steps[j]!); processed.add(j); } } groups.push({ steps: parallelSteps, dependencies: dependencies[i] || [], }); } return groups; } } ``` #### Optimization algorithms (Pillar #3) ![](./assets/ax_optimize.png) ##### MiPRO v2 implementation ```typescript class AxMiPRO extends AxBaseOptimizer { async compile(program: AxGen, metricFn: AxMetricFn): Promise { // Step 1: Bootstrap few-shot examples using teacher-student approach const bootstrappedDemos = await this.bootstrapFewShotExamples(program, metricFn); // Step 2: Generate instruction candidates with contextual awareness const instructions = await this.proposeInstructionCandidates(program); // Step 3: Bayesian optimization loop const { bestConfig, bestScore } = await this.runOptimization( program, bootstrappedDemos, labeledExamples, instructions, validationSet, metricFn ); return { demos: bootstrappedDemos, bestScore, optimizedGen: this.createOptimizedProgram(bestConfig) }; } private async runOptimization(...): Promise<{ bestConfig: ConfigType; bestScore: number }> { let bestConfig: ConfigType = { instruction: instructions[0], bootstrappedDemos: 1, labeledExamples: 1 }; let bestScore = 0; for (let trial = 0; trial < this.numTrials; trial++) { let config: ConfigType; if (this.bayesianOptimization && this.configHistory.length > 2) { config = await this.selectConfigurationViaBayesianOptimization(instructions, bootstrappedDemos, labeledExamples); } else { config = this.randomConfiguration(instructions, bootstrappedDemos, labeledExamples); } const score = await this.evaluateConfig(program, config, validationSet, metricFn); this.updateSurrogateModel(config, score); if (score > bestScore + this.minImprovementThreshold) { bestScore = score; bestConfig = config; } // Early stopping and progress tracking if (this.shouldEarlyStop(trial, bestScore)) break; } return { bestConfig, bestScore }; } } ``` ##### Bayesian optimization with acquisition functions ```typescript private calculateAcquisitionValue(config: ConfigType): number { const prediction = this.predictPerformance(config); const { mean, variance } = prediction; const std = Math.sqrt(variance); const bestScore = Math.max(...this.configHistory.map(entry => entry.score)); switch (this.acquisitionFunction) { case 'expected_improvement': { const improvement = mean - bestScore; if (std === 0) return Math.max(0, improvement); const z = improvement / std; const phi = 0.5 * (1 + this.erf(z / Math.sqrt(2))); // CDF const pdfValue = Math.exp(-0.5 * z * z) / Math.sqrt(2 * Math.PI); // PDF return improvement * phi + std * pdfValue; } case 'upper_confidence_bound': { return mean + this.explorationWeight * std; } case 'probability_improvement': { const improvement = mean - bestScore; if (std === 0) return improvement > 0 ? 1 : 0; const z = improvement / std; return 0.5 * (1 + this.erf(z / Math.sqrt(2))); } } } ``` ##### Bootstrap few shot execution flow The teacher-student pattern that makes your prompts actually good: ```mermaid flowchart TD A[Start: compile method] --> B[Initialize parameters

''; if (i < values.length) { const val = values[i]; // Smart field marker handling for optional/internal fields if (isAxFieldType(val)) { const fieldNameMatch = result.match(/(\w+)\s*:\s*$/); if (fieldNameMatch && (val.isOptional || val.isInternal)) { const fieldName = fieldNameMatch[1]!; let modifiedFieldName = fieldName; if (val.isOptional) modifiedFieldName += '?'; if (val.isInternal) modifiedFieldName += '!'; result = result.replace(/(\w+)(\s*:\s*)$/, `${modifiedFieldName}$2`); } result += convertFieldTypeToString(val); } } } return new AxGen(result); } // Phase 2: Runtime validation with cached results class AxSignature { private validatedAtHash?: string; public validate(): boolean { if (this.validatedAtHash === this.sigHash) { return true; // Use cached validation } this.inputFields.forEach((field) => validateField(field, 'input')); this.outputFields.forEach((field) => validateField(field, 'output')); this.validateSignatureConsistency(); this.validatedAtHash = this.sigHash; // Cache successful validation return true; } } ``` **Result**: Perfect integration of compile-time type checking with runtime validation, enabling both developer productivity and runtime safety. ### Challenge 2: Workflow node also need to be typed (knows the signature input/output) **Why it's a pain**: - Workflows can branch, loop, and merge however they want - State changes every step, collecting more fields - Final signature depends on analyzing the whole execution path - Type info can't get corrupted along the way **How we solved it**: Analyze execution plans and track type changes ```typescript private inferSignatureFromFlow(): AxSignature { const executionPlan = this.executionPlanner.getExecutionPlan(); if (this.nodeGenerators.size === 0 && executionPlan.steps.length === 0) { return this.createDefaultSignature(); } // Analyze data flow through execution plan const allProducedFields = new Set(); const allConsumedFields = new Set(); for (const step of executionPlan.steps) { step.produces.forEach(field => allProducedFields.add(field)); step.dependencies.forEach(field => allConsumedFields.add(field)); } // Input fields = consumed but not produced by any step const inputFieldNames = new Set(); for (const consumed of allConsumedFields) { if (!allProducedFields.has(consumed)) { inputFieldNames.add(consumed); } } // Special handling for final map/merge operations const outputFieldNames = new Set(); const lastStep = executionPlan.steps[executionPlan.steps.length - 1]; if (lastStep && (lastStep.type === 'map' || lastStep.type === 'merge')) { // Use fields produced by final transformation lastStep.produces.forEach(field => { if (!field.startsWith('_')) { // Skip internal fields outputFieldNames.add(field); } }); // Special case: conditional merges that produce _mergedResult if (lastStep.type === 'merge' && lastStep.produces.includes('_mergedResult')) { // Include all node result fields as potential outputs for (const step of executionPlan.steps) { if (step.type === 'execute' && step.produces.length > 0) { step.produces.forEach(field => outputFieldNames.add(field)); } } } } else { // Standard logic: find leaf fields (produced but not consumed) for (const produced of allProducedFields) { let isConsumed = false; for (const step of executionPlan.steps) { if (step.dependencies.includes(produced)) { isConsumed = true; break; } } if (!isConsumed) { outputFieldNames.add(produced); } } } return this.buildSignatureFromAnalysis(inputFieldNames, outputFieldNames); } ``` **The trick**: Treat the workflow like a data flow graph, then use graph analysis to figure out the right signature automatically. **The key trick**: Copy state immutably plus dependency analysis ensures safe parallel execution without race conditions. ### Challenge 3: LLM providers don't like each other **Provider differences**: - Different ways to authenticate (API keys, OAuth, custom headers) - Different request/response formats - Different features (image support, function calling, streaming) - Different error handling and retry approaches - Different rate limits and pricing **How we solved it**: Layered abstraction that detects what each provider can do ```typescript // Base abstraction layer export abstract class AxBaseAI implements AxAIService { abstract getName(): string; abstract getModelInfo(): AxModelInfo; abstract getCapabilities(): AxModelCapabilities; // Unified chat interface async chat(req: AxChatRequest): Promise { // Pre-processing: validate request against capabilities this.validateRequest(req); // Provider-specific implementation const response = await this.chatImplementation(req); // Post-processing: normalize response format return this.normalizeResponse(response); } protected abstract chatImplementation( req: AxChatRequest, ): Promise; } // Provider-specific implementations export class AxAIOpenAI extends AxBaseAI { getCapabilities(): AxModelCapabilities { return { functions: true, streaming: true, vision: this.modelId.includes('vision'), maxTokens: this.getMaxTokensForModel(this.modelId), }; } protected async chatImplementation( req: AxChatRequest, ): Promise { const openaiRequest = this.convertToOpenAIFormat(req); const response = await this.openaiClient.chat.completions.create( openaiRequest, ); return this.convertFromOpenAIFormat(response); } } // Capability-aware routing export class AxAIRouter { selectProvider(requirements: AxCapabilityRequirements): AxAIService { for (const provider of this.providers) { const capabilities = provider.getCapabilities(); if (this.satisfiesRequirements(capabilities, requirements)) { return provider; } } throw new Error('No provider satisfies requirements'); } } ``` **Cool feature**: Automatic fallback chain that keeps capabilities ensures requests always reach a provider that can handle them. ### Challenge 4: DSPy optimization in TypeScript **The problem**: Building complex optimization algorithms like MiPRO v2 in TypeScript while keeping the math correct from the original Python version. **Math stuff that'll melt your brain**: - Bayesian optimization with Gaussian processes - Multiple ways to pick next parameters (EI, UCB, PI) - Teacher-student optimization patterns - Multi-goal optimization with Pareto frontiers - Advanced sampling strategies **How we solved it**: Pure TypeScript version with optional Python backend **WARNING**: Math zone detected, big brains alert ```typescript // Native TypeScript Bayesian optimization class AxMiPRO extends AxBaseOptimizer { private surrogateModel = new Map< string, { mean: number; variance: number } >(); private calculateAcquisitionValue(config: ConfigType): number { const prediction = this.predictPerformance(config); const { mean, variance } = prediction; const std = Math.sqrt(variance); const bestScore = Math.max( ...this.configHistory.map((entry) => entry.score), ); switch (this.acquisitionFunction) { case 'expected_improvement': { const improvement = mean - bestScore; if (std === 0) return Math.max(0, improvement); const z = improvement / std; const phi = 0.5 * (1 + this.erf(z / Math.sqrt(2))); // CDF const pdfValue = Math.exp(-0.5 * z * z) / Math.sqrt(2 * Math.PI); // PDF return improvement * phi + std * pdfValue; } // ... other acquisition functions } } // Error function approximation for statistical calculations private erf(x: number): number { // Abramowitz and Stegun approximation const a1 = 0.254829592, a2 = -0.284496736, a3 = 1.421413741; const a4 = -1.453152027, a5 = 1.061405429, p = 0.3275911; const sign = x >= 0 ? 1 : -1; const absX = Math.abs(x); const t = 1.0 / (1.0 + p * absX); const y = 1.0 - ((((a5 * t + a4) * t + a3) * t + a2) * t + a1) * t * Math.exp(-absX * absX); return sign * y; } // Optional Python backend integration private async compilePython( program: AxGen, metricFn: AxMetricFn, ): Promise { if (!this.pythonClient) throw new Error('Python client not initialized'); const optimizationRequest = { study_name: `mipro_${Date.now()}`, parameters: [ { name: 'temperature', type: 'float', low: 0.1, high: 2.0 }, { name: 'bootstrappedDemos', type: 'int', low: 0, high: this.maxBootstrappedDemos, }, ], objective: { name: 'score', direction: 'maximize' }, n_trials: this.numTrials, sampler: 'TPESampler', }; const job = await this.pythonClient.createOptimizationJob( optimizationRequest, ); // ... handle optimization loop with Python backend } } ``` **Best of both**: Pure TypeScript works in browsers, optional Python backend for advanced math stuff. ## Smart tricks we found Ax doesn't have many tricks to begin with, its selling point is with the signature pattern and collection of optimizers. The biggest trick of Ax/DSPy is how it managed to stay so low-key for so many years that no one has mentioned it in mainstream media (blog posts, tutorials, etc...) until context engineering become the new trend ### Trick 1: Runtime checks that play nice with TypeScript **The problem**: Making sure field names are descriptive at runtime without breaking TypeScript's compile-time checking. **How we did it**: Multiple layers of validation with ~~tons of @ts-ignores~~ compile-time hints. ```typescript function validateField(field: AxField, context: 'input' | 'output'): void { if (!field.name || field.name.length === 0) { throw new AxSignatureValidationError( 'Field name cannot be blank', field.name, ); } // Runtime validation for field name descriptiveness if (axGlobals.signatureStrict) { const reservedNames = [ 'text', 'object', 'data', 'value', 'result', 'response', 'request', 'item', ]; if (reservedNames.includes(field.name.toLowerCase())) { const suggestions = context === 'input' ? ['userInput', 'questionText', 'documentContent', 'messageText'] : ['responseText', 'analysisResult', 'categoryType', 'summaryText']; throw new AxSignatureValidationError( `Field name '${field.name}' is too generic`, field.name, `Use a more descriptive name. Examples: ${suggestions.join(', ')}`, ); } } // Case validation if (!isValidCase(field.name)) { throw new AxSignatureValidationError( `Invalid field name '${field.name}' - must be camelCase or snake_case`, field.name, 'Use camelCase (e.g., "userInput") or snake_case (e.g., "user_input")', ); } } // Type-level enforcement through branded types type DescriptiveFieldName = string & { __brand: 'descriptive' }; function createField(name: DescriptiveFieldName, type: AxFieldType): AxField { return { name, type }; // Compile-time guarantee of descriptive name } ``` **The cool part**: Mix runtime validation with TypeScript's branded types to get both type safety and runtime checks. ### Trick 2: Finding parallel operations automatically **The problem**: Finding operations that can run in parallel without making developers mark them explicitly. **How we did it**: Control flow analysis with execution graph optimization. ```typescript class AxFlowExecutionPlanner { setInitialFields(fields: string[]): void { this.availableFields = new Set(fields); } createOptimizedExecution(batchSize: number): AxFlowStepFunction[] { const executionGraph = this.buildExecutionGraph(); const optimizedGroups = this.optimizeExecution(executionGraph); return optimizedGroups.map((group) => { if (group.length === 1) { return group[0]!.step; } // Create batched parallel execution return async (state: AxFlowState, context: any) => { console.log(`Executing ${group.length} operations in parallel`); const results = await processBatches( group, async (stepInfo, _index) => { const stepResult = await stepInfo.step(state, context); return { [stepInfo.id]: stepResult }; }, batchSize, ); // Merge all parallel results return results.reduce( (merged, result) => ({ ...merged, ...result }), state, ); }; }); } private buildExecutionGraph(): ExecutionNode[] { const nodes: ExecutionNode[] = []; for (let i = 0; i < this.steps.length; i++) { const step = this.steps[i]!; const node: ExecutionNode = { id: i, step: step.step, dependencies: step.dependencies, produces: step.produces, canExecuteAfter: new Set(), mustExecuteBefore: new Set(), }; // Find dependencies on previous steps for (let j = 0; j < i; j++) { const prevStep = this.steps[j]!; const hasDataDependency = step.dependencies.some((dep) => prevStep.produces.includes(dep), ); if (hasDataDependency) { node.canExecuteAfter.add(j); nodes[j]?.mustExecuteBefore.add(i); } } nodes.push(node); } return nodes; } private optimizeExecution(graph: ExecutionNode[]): ExecutionNode[][] { const groups: ExecutionNode[][] = []; const scheduled = new Set(); while (scheduled.size < graph.length) { const readyNodes = graph.filter( (node) => !scheduled.has(node.id) && [...node.canExecuteAfter].every((dep) => scheduled.has(dep)), ); if (readyNodes.length === 0) { throw new Error('Circular dependency detected in execution graph'); } groups.push(readyNodes); readyNodes.forEach((node) => scheduled.add(node.id)); } return groups; } } ``` **Just works**: Complex workflows automatically get parallel execution without any setup.

Crawl4AI breakdown

![](assets/crawl4ai-cheatsheet.png) ## What Crawl4AI does Crawl4AI is a specialized web crawler designed specifically for AI applications. Unlike traditional scrapers that merely extract HTML, it intelligently processes web content to create clean, structured data that language models can effectively utilize. The framework delivers 6x faster performance while producing higher quality results by employing algorithms that identify meaningful content regardless of HTML structure. The output is clean Markdown and structured JSON optimized for AI consumption. For **RAG systems**, it delivers source-tracked content with noise (menus, ads) removed. **AI agents** receive consistently formatted data following predefined schemas. **Training datasets** benefit from filtered, high-quality content, and **real-time applications** can process multiple pages concurrently without performance issues. Crawl4AI's key advantages include independence from external APIs (avoiding rate limits and extra costs), AI-first design philosophy, flexible extraction methods (CSS, XPath, regex, or LLMs), and robust handling of anti-bot measures, session management, and IP rotation. ## How it works under the hood ### Core architecture Crawl4AI implements a layered architecture with clear separation between orchestration, browser management, and content processing: ```mermaid graph TB subgraph "User Interface Layer" CLI[crwl CLI Tool] API[AsyncWebCrawler API] Docker[FastAPI Server :11235] MCP[MCP Protocol] end subgraph "Orchestration Layer" AWC[AsyncWebCrawler] CP[CrawlerPool] ADM[AsyncDatabaseManager] AUS[AsyncUrlSeeder] end subgraph "Browser Management" BM[BrowserManager] APCS[AsyncPlaywrightCrawlerStrategy] MB[ManagedBrowser] BP[BrowserProfiler] end subgraph "Content Processing Pipeline" WSS[WebScrapingStrategy] DMG[DefaultMarkdownGenerator] CF[Content Filters] ES[Extraction Strategies] end CLI --> AWC API --> AWC Docker --> AWC MCP --> AWC AWC --> CP AWC --> ADM AWC --> AUS CP --> BM BM --> APCS APCS --> MB MB --> BP APCS --> WSS WSS --> DMG DMG --> CF CF --> ES %% Highlight the most critical component classDef important fill:#ff6b6b,stroke:#d63031,stroke-width:3px,color:#fff,font-weight:bold %% Apply to core orchestrator only class AWC important ``` ### Execution flow The `AsyncWebCrawler.arun()` method orchestrates the entire crawling process: 1. **Cache check**: Query `AsyncDatabaseManager` for existing results 2. **Browser acquisition**: Get pre-warmed browser instance from `BrowserManager` 3. **Page navigation**: Use `AsyncPlaywrightCrawlerStrategy` for actual crawling 4. **Content processing**: Apply `WebScrapingStrategy` for HTML cleaning 5. **Markdown generation**: Transform content through `DefaultMarkdownGenerator` 6. **Strategy execution**: Run configured `ExtractionStrategy` for structured data 7. **Result assembly**: Package everything into `CrawlResult` object 8. **Cache storage**: Persist results for future use ### Browser management strategy Crawl4AI uses sophisticated browser pooling to handle concurrent requests efficiently: ```python # Browser pool with pre-warmed instances class BrowserManager: def __init__(self): self.browser_pool = {} # Pre-warmed browsers self.session_contexts = {} # Persistent sessions async def get_browser_page(self, config: BrowserConfig): # Return existing or create new browser instance # Handles session persistence, proxy rotation, anti-detection ``` **Key Features:** - **Pre-warmed instances**: Browsers ready before requests arrive - **Session persistence**: Maintain state across multiple crawls - **Anti-detection**: Randomized fingerprints, user agents, viewport sizes - **Profile management**: Persistent user data directories for complex workflows ## Data structures and algorithms ### Core data structures **CrawlResult - The primary output object** ```python @dataclass class CrawlResult: # Basic info url: str # Final URL after redirects success: bool # Crawl success status status_code: int # HTTP status code # Content variants html: str # Raw HTML content cleaned_html: str # Sanitized HTML markdown: MarkdownGenerationResult # Multiple markdown variants # Extracted data extracted_content: str # JSON structured data from strategies media: Dict # Images, videos, tables with metadata links: Dict # Internal/external links with scores # Generated assets screenshot: str # Base64 encoded screenshot pdf: bytes # PDF representation network_logs: List # HTTP request/response logs ``` **Configuration objects hierarchy** ```python # Browser-level configuration BrowserConfig: headless: bool = True user_data_dir: str = None chrome_channel: str = "chrome" browser_type: str = "chromium" # Per-crawl configuration CrawlerRunConfig: cache_mode: CacheMode = CacheMode.ENABLED extraction_strategy: ExtractionStrategy = NoExtractionStrategy() session_id: str = None word_count_threshold: int = 10 content_filter: ContentFilter = None ``` ### Algorithms The content processing algorithms work together in a specific sequence to transform raw HTML into clean, AI-ready content: ```mermaid flowchart TD A[Raw HTML Content] --> B[WebScrapingStrategy Cleanup] B --> C[DefaultMarkdownGenerator] C --> D{Content Filter Type?} D -->|PruningContentFilter| E[PruningContentFilter] D -->|BM25ContentFilter| F[BM25ContentFilter] D -->|LLMContentFilter| G[LLMContentFilter] D -->|None| H[No Filtering] E --> J[Filtered Markdown] F --> J G --> J H --> J J --> K[ExtractionStrategy] K --> L{Strategy Type?} L -->|LLM| M[LLMExtractionStrategy

PruningContentFilter - The Smart content cleaner** The `PruningContentFilter` is Crawl4AI's main content cleaning workhorse. It runs right after the basic HTML cleanup but before the final markdown gets generated. Its job is to throw out the junk (like navigation menus, ads, and footer links) while keeping the actual content you care about. **What makes this different from other tools like Boilerpipe:** - **Smarter link handling**: Instead of just counting links versus text, Crawl4AI actually looks at what kind of links they are and where they appear. A navigation menu gets treated differently than a citation in an article. - **Works with multiple crawlers**: When you're running several browser instances at the same time, each filter keeps its own state so they don't interfere with each other. - **Self-adjusting thresholds**: This is the clever bit - the filter adapts to different types of pages: - `"fixed"` mode: Every piece of content needs to hit the same score to survive - `"dynamic"` mode: The scoring adjusts based on what type of page it's looking at, so it doesn't accidentally remove good content from sparse pages or leave junk on cluttered ones Everything happens in memory while processing, and the results get cached so you don't have to reprocess the same URL later. ```python class PruningContentFilter: def __init__(self, threshold: float = 0.48, threshold_type: str = "dynamic"): self.threshold = threshold self.threshold_type = threshold_type # "fixed" or "dynamic" def filter_content(self, content: str) -> str: # Parse DOM and calculate node scores # Apply link density heuristics # Use dynamic thresholding for adaptive filtering # Return pruned content with high information density ``` **2. BM25 content filtering** The BM25 filter kicks in during content processing, right after the HTML gets cleaned up but before it becomes final markdown. When you give it a search query, Crawl4AI uses this to keep only the content that actually matches what you're looking for, which makes the output much more focused. **How it works:** The filter breaks content into chunks and scores how well each chunk matches your query terms using the [BM25 algorithm](https://www.geeksforgeeks.org/nlp/what-is-bm25-best-matching-25-algorithm/) (a variation of TF-IDF that's better for short documents). It then throws out anything that doesn't score high enough. ```python class BM25ContentFilter: def __init__(self, user_query: str, bm25_threshold: float = 1.0): self.query_terms = user_query.lower().split() self.threshold = bm25_threshold def filter_content(self, content: str) -> str: # Calculate BM25 scores for content chunks # Filter chunks below threshold # Return high-relevance content only ``` This runs when you set up the `content_filter` parameter in your crawler config. It happens after the basic HTML cleanup but before the final markdown gets generated. The filter breaks content into chunks and scores how well each chunk matches your query terms, then throws out anything that doesn't score high enough. **3. Strategy pattern for extraction** Crawl4AI uses the Strategy pattern to support multiple extraction methods. This allows you to choose the best approach for each website - whether that's AI-powered extraction for complex pages, CSS selectors for structured sites, or regex patterns for predictable content. **Available strategies:** - **LLM-based**: Uses AI models for intelligent, flexible extraction - **CSS-based**: Fast extraction using CSS selectors with JSON schema mapping - **Regex-based**: Pattern matching for predictable, structured content ```python class ExtractionStrategy(ABC): @abstractmethod async def extract(self, url: str, html: str) -> str: pass # Concrete implementations class LLMExtractionStrategy(ExtractionStrategy): # Uses OpenAI/Anthropic/Ollama for intelligent extraction class JsonCssExtractionStrategy(ExtractionStrategy): # Uses CSS selectors with JSON schema mapping class RegexExtractionStrategy(ExtractionStrategy): # Pattern-based extraction for structured content ``` **4. Priority queue for deep crawling** For deep crawling scenarios where you need to explore multiple pages from a starting URL, Crawl4AI uses a priority queue to intelligently decide which pages to crawl next. This ensures the most relevant or important pages are processed first. **How it works:** URLs are scored based on factors like link relevance, page importance, and content quality. The crawler then processes the highest-scoring URLs first, making deep crawling much more efficient than simple breadth-first or depth-first approaches. ```python class BestFirstCrawlStrategy: def __init__(self): self.url_queue = PriorityQueue() # (score, url) tuples self.visited = set() async def crawl(self, start_url: str, max_pages: int): while not self.url_queue.empty() and len(self.visited) < max_pages: score, url = await self.url_queue.get() # Process highest-scoring URLs first ``` **5. Adaptive learning - Getting smarter over time** The learning system kicks in after each successful crawl to figure out what worked well and what didn't. It tracks how good the extraction was and adjusts its approach for similar websites in the future. All this learning gets saved to a local SQLite database, so the crawler gets better at handling specific sites over time. **Learning process:** The system analyzes extraction quality, updates pattern weights, and persists learned strategies. This happens in the background after each crawl, with updates batched every 10 successful extractions to maintain performance during heavy crawling. ```python class AdaptiveConfig: def __init__(self): self.pattern_history = {} # URL patterns → extraction success self.persistence_manager = SQLitePatternStore() def learn_from_result(self, url: str, extraction_quality: float): # Update pattern weights based on extraction success # Persist learned patterns for future sessions # Improve future extraction strategies ``` ## Technical challenges and solutions ### Challenge 1: Browser anti-detection **Problem**: Modern websites use sophisticated bot detection including fingerprinting, behavioral analysis, and CAPTCHA systems. **Solution**: Multi-layered anti-detection strategy Crawl4AI implements several layers of anti-detection to bypass modern bot detection systems. This includes randomized browser fingerprints, behavioral simulation, and proxy rotation to make requests appear more human-like. **Anti-detection techniques:** - **Fingerprint randomization**: Rotating user agents, viewport sizes, locales, and timezones - **Behavioral simulation**: Human-like scrolling, mouse movements, and timing delays - **Proxy rotation**: Distributing requests across multiple IP addresses - **Session persistence**: Maintaining cookies and state like real users ```python # Randomized browser fingerprints browser_config = BrowserConfig( user_agent_mode="random", # Rotate user agents viewport_width=random.randint(1024, 1920), viewport_height=random.randint(768, 1080), locale=random.choice(["en-US", "en-GB", "de-DE"]), timezone_id=random.choice(["America/New_York", "Europe/London"]) ) # Stealth techniques magic=True # Enable stealth mode proxy_config=ProxyConfig(rotation_enabled=True) ``` ### Challenge 2: Large-scale concurrent crawling **Problem**: Memory exhaustion and resource contention when crawling thousands of URLs concurrently. **Solution**: Memory-adaptive dispatching with intelligent resource management To handle large-scale concurrent crawling without overwhelming system resources, Crawl4AI implements intelligent resource management that monitors system memory and adjusts crawling behavior accordingly. **Resource management features:** - **Memory monitoring**: Dynamically adjusts concurrency based on available system memory - **Semaphore-based rate limiting**: Controls the number of concurrent browser instances - **Browser pooling**: Reuses browser instances across requests to reduce overhead - **Graceful degradation**: Reduces concurrency under memory pressure ```python class MemoryAdaptiveDispatcher: def __init__(self, memory_threshold: float = 0.8): self.memory_threshold = memory_threshold self.active_crawlers = 0 async def dispatch_crawl(self, url: str): current_memory = psutil.virtual_memory().percent / 100 if current_memory > self.memory_threshold: await self.wait_for_memory_relief() # Proceed with crawl only when memory is available ``` ### Challenge 3: Content quality for LLMs **Problem**: Raw web content contains navigation menus, ads, footers, and other noise that degrades LLM performance. **Solution**: Multiple content filtering strategies Crawl4AI provides three main content filter types that can be used individually or in combination to transform raw web content into clean, AI-ready text: **Available content filters:** - **PruningContentFilter**: Heuristic-based filtering using text density, link density, and tag importance - **BM25ContentFilter**: Query-based relevance filtering using BM25 ranking algorithm - **LLMContentFilter**: AI-powered intelligent content filtering and formatting ```python # Heuristic-based filtering (most common) content_filter = PruningContentFilter(threshold=0.48, threshold_type="dynamic") # Query-based filtering for targeted content content_filter = BM25ContentFilter(user_query="product information", bm25_threshold=1.0) # AI-powered filtering for intelligent selection content_filter = LLMContentFilter(instruction="Keep only product details and specifications") # Configure crawler with chosen filter config = CrawlerRunConfig(content_filter=content_filter) result = await crawler.arun(url, config=config) ``` ### Challenge 4: Dynamic content handling **Problem**: JavaScript-heavy websites with infinite scroll, lazy loading, and dynamic content generation. **Solution**: Advanced browser automation with virtual scrolling For JavaScript-heavy websites with infinite scroll, lazy loading, and dynamic content, Crawl4AI uses advanced browser automation techniques to ensure all content is captured. **Dynamic content strategies:** - **Virtual scrolling**: Automatically detects and handles infinite scroll pages - **JavaScript execution**: Runs custom JS code to trigger dynamic content loading - **Wait strategies**: Intelligently waits for content to load before proceeding - **Content change detection**: Monitors DOM changes to ensure completeness ```python # Virtual scroll configuration for infinite content virtual_scroll_config = VirtualScrollConfig( wait_time=2.0, # Wait between scroll actions check_scroll_position=True, # Detect scroll position changes max_scroll_attempts=10, # Limit scroll attempts scroll_delay=1.0 # Delay between scrolls ) # Execute JavaScript for dynamic content js_code = [ "window.scrollTo(0, document.body.scrollHeight);", "await new Promise(resolve => setTimeout(resolve, 2000));", "return document.querySelectorAll('.dynamic-content').length;" ] ``` ## Clever tricks and tips ### Performance optimizations **1. Browser pool pre-warming** ```python # Pre-warm browser instances during application startup async def setup_browser_pool(): browser_manager = BrowserManager() # Create 5 ready-to-use browser instances for i in range(5): await browser_manager.create_browser_instance() ``` **2. Intelligent caching strategy** ```python # Cache modes for different use cases cache_config = { "development": CacheMode.BYPASS, # Always fresh content "production": CacheMode.ENABLED, # Use cache when available "research": CacheMode.READ_ONLY, # Never update cache "batch_processing": CacheMode.WRITE_ONLY # Always cache results } ``` **3. Chunk-based processing for large content** ```python # Process large documents in chunks to avoid memory issues def process_large_content(content: str, chunk_size: int = 10000): chunks = [content[i:i+chunk_size] for i in range(0, len(content), chunk_size)] processed_chunks = [process_chunk(chunk) for chunk in chunks] return "".join(processed_chunks) ``` ### AI-Specific features **1. Schema-based extraction with Pydantic** ```python from pydantic import BaseModel class ProductInfo(BaseModel): name: str price: float description: str availability: bool # LLM extracts data conforming to schema extraction_strategy = LLMExtractionStrategy( schema=ProductInfo.schema(), instruction="Extract product information from the page" ) ``` **2. Multiple markdown variants** ```python # Different markdown formats for different use cases result = await crawler.arun(url) raw_content = result.markdown.raw_markdown # Unfiltered clean_content = result.markdown.fit_markdown # Filtered for quality cited_content = result.markdown.markdown_with_citations # With source links references = result.markdown.references_markdown # Citation list ``` **3. Network traffic analysis** ```python # Capture network requests for debugging and analysis config = CrawlerRunConfig( capture_network=True, capture_console=True ) result = await crawler.arun(url, config=config) # Access network logs for API discovery, performance analysis network_requests = result.network_logs console_messages = result.console_messages ``` ## Considerations **Performance trade-offs:** - **LLM strategies** provide highest accuracy but cost $0.001-0.01 per page - **CSS/XPath strategies** are free and fast (~50ms) but require structured HTML - **Browser pooling** improves performance but increases memory usage - **Caching** reduces API calls but may serve stale content **Reliability concerns:** - **Anti-detection bypassing** may violate website terms of service - **Large-scale crawling** can overwhelm target servers without rate limiting - **Session persistence** requires careful cleanup to avoid memory leaks - **Browser automation** depends on Playwright which may break with browser updates **Cost optimization:** - Use **hybrid strategies**: Generate schemas once with LLM, reuse with CSS extraction - Implement **smart caching** to avoid re-crawling unchanged content - Configure **memory thresholds** to prevent system resource exhaustion - Apply **content filtering** before expensive LLM processing --- #### References - [Crawl4AI GitHub Repository](https://github.com/unclecode/crawl4ai) - [Crawl4AI Official Documentation](https://docs.crawl4ai.com/) - [DeepWiki Crawl4AI Analysis](https://deepwiki.com/unclecode/crawl4ai)

Zen MCP breakdown

![](assets/zen-mcp-cheatsheet.png) ## Overview The Zen MCP Server is a sophisticated Model Context Protocol (MCP) server that enables multi-AI orchestration, conversation memory, and advanced workflow management. ### Solved problems Traditional MCP tools call are stateless - each request is independent, with no memory. For complex tasks, this creates significant friction: - **Context loss**: Need to re-explain the same codebase across multiple interactions - **Tool isolation**: Different AI tools can't build upon each other's work - **Manual state magements**: Developers must manually manage state between AI interactions - **Inefficient workflows**: Repetitive context setting for systematic analysis tasks ### Key technical advances 1. **Stateless-to-stateful bridge**: Converts MCP's inherently stateless protocol into persistent conversation threads 2. **Cross-tool continuation**: Seamless handoffs between different tools while preserving full context 3. **Dual prioritization strategy**: Sophisticated file and conversation prioritization with token-aware budgeting 4. **Multi-provider architecture**: Unified interface supporting multiple AI providers (Gemini, OpenAI, OpenRouter, Custom APIs) 5. **Workflow-enforced tools**: Advanced tools that enforce systematic investigation patterns ### Tool categories and responsibilities **Simple tools (4 tools)**: - `chat`: General conversation and collaborative thinking - `challenge`: Critical analysis to prevent reflexive agreement - `listmodels`: Display available AI models by provider - `version`: Server version and configuration information **Workflow tools (11 tools)**: - `thinkdeep`: Multi-stage workflow for complex problem analysis - `debug`: Systematic self-investigation for root cause analysis - `analyze`: Comprehensive code analysis with expert validation - `codereview`: Step-by-step code review with security focus - `consensus`: Multi-model consensus with stance-based analysis - `planner`: Interactive sequential planning with branching - `secaudit`: Comprehensive security audit workflow - `testgen`: Test generation with edge case coverage - `refactor`: Refactoring analysis with code smell detection - `precommit`: Pre-commit validation workflow - `docgen`: Documentation generation workflow **Special Tools (2 tools)**: - `tracer`: Code tracing workflow for execution flow analysis - `challenge`: Hybrid tool preventing reflexive agreement **Multi-provider AI Access**: - **Direct APIs**: Gemini, OpenAI, X.AI GROK - **Aggregated APIs**: OpenRouter (50+ models) - **Local models**: Ollama, vLLM, LM Studio - **Unified APIs**: DIAL platform - **Auto selection**: Intelligent model routing based on task requirements ### Usecases **Scenario 1 - Cross-tool investigation**: ``` 1. Claude: "Analyze this codebase for security issues" → analyze tool creates thread_id, examines architecture 2. Claude: "Now do a detailed security audit" + continuation_id=thread_id → secaudit tool sees FULL analyze context + files, performs deep security review 3. Claude: "Debug the SQL injection issues found" + continuation_id=thread_id → debug tool sees BOTH analyze + secaudit findings, debugs specific vulnerabilities ``` **Scenario 2 - Multi-model consensus**: ``` Claude: "Should we migrate from Express to Fastify?" → consensus tool calls: - O3 (arguing FOR migration) - Gemini (arguing AGAINST migration) - O3-mini (neutral analysis) → Returns synthesized recommendation with evidence from all perspectives ``` **Scenario 3 - Context revival after reset**: ``` 1. Long conversation with Claude analyzing complex system 2. Claude's context gets reset (hits token limit) 3. User: "Continue our discussion" + continuation_id 4. New Claude instance gets FULL conversation history 5. Seamless continuation as if context never reset ``` ## How it works ### Architecture overview ```mermaid graph TD CLI[Claude CLI

File deduplication algorithm **Problem**: In multi-turn conversations, the same files get requested repeatedly. Without deduplication, a 50KB file could be embedded in every turn, quickly exhausting token budgets and degrading performance. **Why this matters**: A typical 5-turn conversation might request the same 3 files repeatedly, resulting in 15 file embeddings instead of 3 unique ones. This wastes 80% of the file token budget. **Solution**: The filter_new_files algorithm tracks which files have been embedded in previous conversation turns and only embeds truly new files. Previously embedded files remain accessible through conversation history. ```python def filter_new_files(self, requested_files: list[str], continuation_id: Optional[str]) -> list[str]: """Prevents duplicate file embeddings using conversation history""" if not continuation_id: return requested_files # New conversation, all files are new # Get files already embedded in conversation embedded_files = set(self.get_conversation_embedded_files(continuation_id)) # Return only files that haven't been embedded yet new_files = [f for f in requested_files if f not in embedded_files] logger.debug(f"Filtered {len(requested_files) - len(new_files)} duplicate files") return new_files ``` - **Time complexity**: O(n) where n = number of conversation turns - **Space complexity**: O(f) where f = unique files across conversation - **Cache behavior**: Files cached in conversation memory, not re-read from disk #### 2. Token budget allocation algorithm **Problem**: Different AI models have vastly different context windows (O3: 200K tokens, Gemini: 1M tokens). A one-size-fits-all allocation strategy either underutilizes large models or overwhelms small ones. **Why this matters**: Poor token allocation leads to either truncated conversations (losing important context) or inefficient usage (leaving 800K tokens unused on Gemini models). **Solution**: The calculate_token_allocation algorithm dynamically adjusts allocation ratios based on model capacity. Smaller models prioritize conversation history over files, while larger models can afford generous file embedding. ```python def calculate_token_allocation(self, reserved_for_response: Optional[int] = None) -> TokenAllocation: """Model-specific token budgeting for optimal context utilization""" total_tokens = self.capabilities.context_window # Dynamic allocation based on model capacity if total_tokens < 300_000: content_ratio, response_ratio = 0.6, 0.4 # Conservative for smaller models file_ratio, history_ratio = 0.3, 0.5 # Prioritize conversation history else: content_ratio, response_ratio = 0.8, 0.2 # Generous for large models file_ratio, history_ratio = 0.4, 0.4 # Balanced allocation return TokenAllocation( total_tokens=total_tokens, content_tokens=int(total_tokens * content_ratio), response_tokens=int(total_tokens * response_ratio), file_tokens=int(content_tokens * file_ratio), history_tokens=int(content_tokens * history_ratio), ) def build_conversation_history(context: ThreadContext, token_budget: int) -> str: total_tokens = 0 included_turns = [] # Process turns newest-to-oldest for budget allocation for idx in range(len(context.turns) - 1, -1, -1): turn = context.turns[idx] turn_tokens = estimate_tokens(turn.content) if total_tokens + turn_tokens > token_budget: break # Exclude older turns first included_turns.append((idx, turn.content)) total_tokens += turn_tokens # Reverse for chronological presentation included_turns.reverse() # Build final conversation string conversation_parts = [] for idx, content in included_turns: conversation_parts.append(f"Turn {idx + 1}: {content}") if len(included_turns) < len(context.turns): conversation_parts.insert(0, f"[Showing most recent {len(included_turns)} of {len(context.turns)} turns]") return "\n\n".join(conversation_parts) ``` **Adaptive behavior**: - **O3 models** (200K context): Conservative split, prioritize history over files - **Gemini models** (1M context): Generous split, balanced file/history allocation #### 3. Provider resolution algorithm **Problem**: Multiple AI providers offer overlapping models with different performance characteristics. Users shouldn't need to know which provider hosts which model. **Why this matters**: Direct APIs (Google, OpenAI) offer better performance and cost than aggregated APIs (OpenRouter), but don't support all models. A poor routing strategy could send all requests to the slowest provider. **Solution**: The get_provider_for_model algorithm routes through a performance-optimized priority order: Direct APIs first, then unified APIs, then catch-all providers. First match wins. ```python def get_provider_for_model(cls, model_name: str) -> Optional[ModelProvider]: """Route model requests through provider priority order""" PROVIDER_PRIORITY_ORDER = [ ProviderType.GOOGLE, # Direct APIs first (performance + cost) ProviderType.OPENAI, ProviderType.XAI, ProviderType.DIAL, # Unified APIs second ProviderType.CUSTOM, # Local models third ProviderType.OPENROUTER, # Catch-all last ] for provider_type in PROVIDER_PRIORITY_ORDER: provider = cls.get_provider(provider_type) if provider and provider.validate_model_name(model_name): return provider # First match wins return None # No provider supports this model ``` - **Direct APIs**: Lowest latency, best cost efficiency - **Aggregated APIs**: Broader model selection, higher latency - **Local APIs**: Privacy + control, limited model selection #### 4. Dual prioritization strategy **Problem**: For optimal token usage, we want newest content first (recent context is most relevant). But for LLM understanding, we want chronological order (natural conversation flow). **Why this matters**: When token budgets are tight, we must choose which content to exclude. Excluding the most recent context would break conversation coherence, but presenting content out-of-order confuses LLMs. **Solution**: Two-phase approach that prioritizes newest content but presents chronologically. ```python def get_prioritized_files(context: ThreadContext) -> list[str]: # Phase 1: Collection (Newest-First Priority) seen_files = set() prioritized_files = [] # Walk backwards through turns (newest to oldest) for i in range(len(context.turns) - 1, -1, -1): turn = context.turns[i] for file_path in turn.files or []: if file_path not in seen_files: prioritized_files.append(file_path) # Newest reference wins seen_files.add(file_path) # Phase 2: Presentation (Chronological Order) prioritized_files.reverse() # Now oldest-first for LLM understanding return prioritized_files ``` ### Storage and memory management **Data structure**: Hash map with expiration tracking ```python class InMemoryStorage: def __init__(self): self._store = {} # thread_id -> ThreadContext JSON self._expiry = {} # thread_id -> expiration timestamp self._lock = threading.Lock() # Thread safety def store(self, thread_id: str, context: ThreadContext): with self._lock: self._store[thread_id] = context.model_dump_json() self._expiry[thread_id] = time.time() + (3 * 3600) # 3 hours TTL def get(self, thread_id: str) -> Optional[ThreadContext]: with self._lock: if thread_id not in self._store: return None # Check expiration if time.time() > self._expiry[thread_id]: del self._store[thread_id] del self._expiry[thread_id] return None return ThreadContext.model_validate_json(self._store[thread_id]) ``` **Operations**: - **Create**: O(1) with JSON serialization overhead - **Read**: O(1) with JSON deserialization overhead - **Update**: O(1) replacement of entire context - **Delete**: O(1) explicit deletion, automatic via TTL cleanup **Key characteristics**: - **TTL**: 3 hours (configurable via `CONVERSATION_TIMEOUT_HOURS`) - **Turn limit**: 20 turns max (configurable via `MAX_CONVERSATION_TURNS`) - **Thread safety**: All operations protected by threading.Lock() - **Automatic cleanup**: Expired threads removed on access #### Conversation chains ```python # Parent-child thread relationships enable conversation spanning thread_1 = create_thread("analyze", initial_request) thread_2 = create_thread("codereview", follow_up, parent_thread_id=thread_1) # build_conversation_history() traverses entire chain def build_conversation_history(context: ThreadContext): if context.parent_thread_id: parent_context = get_thread(context.parent_thread_id) parent_history = build_conversation_history(parent_context) return f"{parent_history}\n{current_history}" ``` ## Technical challenges and solutions ### Challenge 1: Stateless protocol + stateful conversations **The problem**: MCP is inherently stateless. Each tool call is independent with no knowledge of previous interactions. But real AI collaboration requires memory. **The solution: In-memory process-persistent storage** ```python # server.py: Single persistent process handles all requests # utils/conversation_memory.py: Thread-safe in-memory storage def create_thread(tool_name: str, initial_request: dict) -> str: thread_id = str(uuid.uuid4()) # Cryptographically secure IDs context = ThreadContext( thread_id=thread_id, tool_name=tool_name, turns=[], # Empty initially initial_context=filtered_request ) # Store with 3-hour TTL storage.setex(f"thread:{thread_id}", CONVERSATION_TIMEOUT_SECONDS, context.json()) return thread_id ``` **Why this works**: - **Performance**: O(1) thread lookup, no I/O overhead - **Simplicity**: No external dependencies, pure Python - **Security**: UUID-based keys prevent injection attacks - **Auto-cleanup**: TTL prevents memory leaks **Trade-offs**: - ❌ **Process restart** loses conversations (acceptable for development tool) - ❌ **Single process** (not distributed), but MCP is single-process anyway - ✅ **Perfect for MCP use case**: Desktop integration, development workflows ### Challenge 2: file content deduplication **The problem**: In multi-turn conversations, the same files get requested repeatedly. Embedding the same 50KB file in every turn wastes tokens and degrades performance. **The solution: Conversation-aware file filtering** ```python def filter_new_files(self, requested_files: list[str], continuation_id: Optional[str]) -> list[str]: if not continuation_id: return requested_files # New conversation, all files are new embedded_files = set(self.get_conversation_embedded_files(continuation_id)) new_files = [f for f in requested_files if f not in embedded_files] logger.debug(f"Filtered {len(requested_files) - len(new_files)} duplicate files") return new_files ``` **The Magic**: Tools can request `["file1.py", "file2.py", "file3.py"]` but only new files are actually embedded. Previously embedded files are accessible through conversation history. **Example**: ``` Turn 1: analyze tool requests ["auth.py", "user.py"] → Both embedded (2 files) Turn 2: codereview tool requests ["auth.py", "user.py", "test.py"] → Only test.py embedded (1 file) Turn 3: debug tool requests ["auth.py", "bug.py"] → Only bug.py embedded (1 file) Total: 4 unique files embedded across 3 turns instead of 7 total files ``` ### Challenge 3: Cross-tool context sharing **The problem**: How do you hand off context from `analyze` tool to `codereview` tool to `debug` tool seamlessly? **The MCP reality**: Each tool call is completely independent. No shared state, no knowledge of previous tools. **The solution: Context injection via conversation reconstruction** ```python async def reconstruct_thread_context(arguments: dict[str, Any]) -> dict[str, Any]: """Transform stateless MCP request into stateful continuation""" # 1. Load full conversation thread context = get_thread(continuation_id) # 2. Build comprehensive history with dual prioritization conversation_history, tokens_used = build_conversation_history( context, model_context=model_context, read_files_func=read_files ) # 3. Inject into current tool's prompt user_prompt = arguments.get("prompt", "") enhanced_prompt = f"{conversation_history}\n\n{user_prompt}" arguments["prompt"] = enhanced_prompt # 4. Pass remaining token budget to tool token_allocation = model_context.calculate_token_allocation() remaining_tokens = token_allocation.content_tokens - tokens_used arguments["_remaining_tokens"] = remaining_tokens return arguments ``` **What the tool sees**: ```` === CONVERSATION HISTORY (CONTINUATION) === Thread: abc-123-def Tool: analyze Turn 2/20 === FILES REFERENCED IN THIS CONVERSATION === The following files have been shared and analyzed: ```12:45:auth/user.py class UserManager: def authenticate(self, username, password): # SECURITY ISSUE: Plain text password comparison return self.users.get(username) == password ``` === END REFERENCED FILES === Previous conversation turns: --- Turn 1 (Claude) --- Files used: auth/user.py, auth/session.py Analyze this authentication system for security vulnerabilities. --- Turn 2 (Gemini using analyze via google/gemini-2.5-flash) --- I found several critical security issues: 1. Plain text password storage and comparison 2. No session timeout mechanism 3. Missing CSRF protection [... full analysis ...] === END CONVERSATION HISTORY === CURRENT REQUEST: Now do a comprehensive security audit focusing on the issues found. ```` **Result**: The `secaudit` tool has complete context from the `analyze` tool without any manual re-explanation. ### Challenge 4: Token budget management across models **The problem**: Different AI models have vastly different context windows: - **O3**: 200K tokens - **Gemini 2.5**: 1M tokens - **Custom models**: 8K-128K tokens How do you allocate tokens efficiently across conversation history, file content, and response space? **The solution: Adaptive token allocation strategy** ```python def calculate_token_allocation(self) -> TokenAllocation: total_tokens = self.capabilities.context_window # Dynamic allocation based on model capacity if total_tokens < 300_000: # Smaller models: Conservative allocation content_ratio = 0.6 # 60% for content response_ratio = 0.4 # 40% for response file_ratio = 0.3 # 30% of content for files history_ratio = 0.5 # 50% of content for conversation else: # Larger models: Generous allocation content_ratio = 0.8 # 80% for content response_ratio = 0.2 # 20% for response file_ratio = 0.4 # 40% of content for files history_ratio = 0.4 # 40% of content for conversation return TokenAllocation( total_tokens=total_tokens, content_tokens=int(total_tokens * content_ratio), response_tokens=int(total_tokens * response_ratio), file_tokens=int(content_tokens * file_ratio), history_tokens=int(content_tokens * history_ratio), ) ``` **Examples**: **O3 Model (200K tokens)**: - Content: 120K tokens (60%) - Response: 80K tokens (40%) - Files: 36K tokens (30% of content) - History: 60K tokens (50% of content) - Tool prompts: 24K tokens (remaining) **Gemini 2.5 Pro (1M tokens)**: - Content: 800K tokens (80%) - Response: 200K tokens (20%) - Files: 320K tokens (40% of content) - History: 320K tokens (40% of content) - Tool prompts: 160K tokens (remaining) **Adaptive behavior**: Smaller models prioritize conversation history over files. Larger models can afford generous file embedding. ### Challenge 5: Workflow tool step enforcement **The problem**: How do you ensure users actually investigate between workflow steps instead of just calling the tool repeatedly without doing any work? **The solution: Forced pause with required actions** ```python def get_step_guidance_message(self, request) -> str: next_step = request.step_number + 1 return ( f"MANDATORY: DO NOT call the {self.get_name()} tool again immediately. " f"You MUST first work using appropriate tools. " f"REQUIRED ACTIONS before calling {self.get_name()} step {next_step}:" f"\n{self._get_required_actions(request)}" ) def _get_required_actions(self, request) -> str: """Tool-specific actions based on current progress""" if request.confidence == "low": return ( "- Search for code related to the reported issue\n" "- Examine relevant files and understand implementation\n" "- Trace method calls and data flow through system" ) elif request.confidence == "high": return ( "- Examine exact code sections where you believe issue occurs\n" "- Verify your hypothesis with code analysis\n" "- Confirm root cause before proceeding" ) ``` **Enforcement mechanism**: The tool responds with required actions but does NOT continue automatically. This forces Claude to actually do the investigation work before the next step. **Example flow**: ``` 1. User calls debug tool step 1 → Tool returns investigation guidance 2. Claude MUST use codebase_search, read_file, grep_search tools 3. Only after investigation can Claude call debug tool step 2 4. Step 2 has NEW evidence from actual code examination 5. Process repeats until confidence = "certain" ``` **Why this works**: - ✅ **Enforces thoroughness**: No shortcuts allowed - ✅ **Builds evidence**: Each step requires new findings - ✅ **Natural workflow**: Mimics real debugging process - ✅ **Quality control**: Tools track confidence progression ### Challenge 6: Multi-provider model routing **The problem**: Supporting 6+ different AI providers (Google, OpenAI, OpenRouter, XAI, DIAL, Custom) with different APIs, model names, capabilities, and failure modes. **Why it's hard**: - Each provider has different authentication, endpoints, and request formats - Model names aren't standardized (gpt-4o vs gemini-2.5-pro vs claude-sonnet-4) - Capabilities vary wildly (context windows, image support, temperature constraints) - Failures need different retry strategies **The solution**: Priority-based provider registry with graceful fallbacks ```python # Provider priority order optimizes for performance and cost PROVIDER_PRIORITY_ORDER = [ ProviderType.GOOGLE, # Direct APIs first (fastest, cheapest) ProviderType.OPENAI, ProviderType.XAI, ProviderType.DIAL, # Unified APIs next ProviderType.CUSTOM, # Local models (privacy but lower availability) ProviderType.OPENROUTER, # Catch-all last (higher latency, cost) ] def get_provider_for_model(model_name: str) -> Optional[ModelProvider]: """Route model to first available provider that supports it""" for provider_type in PROVIDER_PRIORITY_ORDER: provider = get_provider(provider_type) # Skip if provider not configured or available if not provider or not provider.is_available(): continue # Check if provider supports this model if provider.validate_model_name(model_name): return provider return None # No provider found # Each provider handles its own model validation and aliases class GeminiProvider(ModelProvider): MODEL_ALIASES = { "flash": "gemini-2.5-flash", "pro": "gemini-2.5-pro", "flash2": "gemini-2.0-flash" } def validate_model_name(self, model_name: str) -> bool: canonical_name = self.MODEL_ALIASES.get(model_name.lower(), model_name) return canonical_name in self.SUPPORTED_MODELS class OpenRouterProvider(ModelProvider): def validate_model_name(self, model_name: str) -> bool: return True # OpenRouter accepts any model, validates at API level ``` **Robustness**: This architecture gracefully handles provider outages, API key issues, and model availability changes without user-visible failures. ### Challenge 7: Auto vs manual model selection **The problem**: Users want both simplicity (just work!) and control (use the right model for the job). How do you provide both without confusing UX? **Why it's hard**: - Different tasks need different models (reasoning vs speed vs cost) - Available models depend on configured API keys - Users have varying levels of AI model expertise - Tool schemas must adapt to available models **The solution**: Effective auto mode with intelligent defaults by using 4-Layer Architecture The automatic model selection system operates through four sophisticated layers: #### Layer 1: Configuration detection (`config.py`) ```python # Auto mode activation patterns DEFAULT_MODEL = "auto" # Explicit auto mode DEFAULT_MODEL = "unavailable-model" # Fallback to auto mode ``` **Auto mode logic**: ```python def is_effective_auto_mode(self) -> bool: # Case 1: Explicit auto mode if DEFAULT_MODEL.lower() == "auto": return True # Case 2: Model not available (fallback to auto) provider = ModelProviderRegistry.get_provider_for_model(DEFAULT_MODEL) return not bool(provider) ``` #### Layer 2: Tool category requirements **Tool category distribution**: - **EXTENDED_REASONING**: - Tools: `thinkdeep`, `debug`, `analyze`, `codereview`, `secaudit`, `testgen`, `refactor`, `docgen`, `precommit`, `planner`, `tracer`, `consensus` - Selection priority: `o3` → `grok-3` → `gemini-2.5-pro` → `openrouter thinking models` - **FAST_RESPONSE**: - Tools: `chat`, `challenge`, `listmodels`, `version` - Selection priority: `o4-mini` → `o3-mini` → `grok-3-fast` → `gemini-2.5-flash` - **BALANCED**: Default fallback category for new tools - Selection priority: `o4-mini` → `o3-mini` → `grok-3` → `gemini-2.5-flash` #### Layer 3: Provider priority routing **Provider priority order**: ```python PROVIDER_PRIORITY_ORDER = [ ProviderType.GOOGLE, # Direct Gemini access (highest priority) ProviderType.OPENAI, # Direct OpenAI access ProviderType.XAI, # Direct X.AI GROK access ProviderType.DIAL, # DIAL unified API access ProviderType.CUSTOM, # Local/self-hosted models ProviderType.OPENROUTER, # Catch-all for cloud models (lowest priority) ] ``` **Model resolution algorithm**: ```python def get_provider_for_model(model_name: str) -> Optional[ModelProvider]: for provider_type in PROVIDER_PRIORITY_ORDER: provider = get_provider(provider_type) if provider and provider.validate_model_name(model_name): return provider # First match wins return None ``` #### Layer 4: Early resolution (`server.py:639`) **Request Processing Flow**: ```python # Early model resolution prevents runtime failures if model_name.lower() == "auto": tool_category = tool.get_model_category() resolved_model = ModelProviderRegistry.get_preferred_fallback_model(tool_category) arguments["model"] = resolved_model # Model validation and context creation provider = ModelProviderRegistry.get_provider_for_model(model_name) model_context = ModelContext(model_name, provider, capabilities) arguments["_model_context"] = model_context ``` ### Model restriction **Environment-based restrictions**: ```bash OPENAI_ALLOWED_MODELS="o3-mini,o4-mini" GOOGLE_ALLOWED_MODELS="flash,pro" OPENROUTER_ALLOWED_MODELS="opus,sonnet" ``` **Multi-level enforcement**: 1. **Provider level**: Applied during model validation 2. **Schema generation**: Restricted models excluded from enums 3. **Alias-aware**: Checks both canonical names and aliases 4. **Graceful gallback**: Intelligent alternative selection ## Clever tricks and tips we discovered ### Trick 1: The "newest-first" file strategy **The challenge**: In multi-turn conversations, the same file often appears multiple times. Which version should we use? **The solution**: Walk backwards through conversation turns so newer file references take precedence: ```python def get_conversation_file_list(context: ThreadContext) -> list[str]: seen_files = set() file_list = [] # Walk BACKWARDS (newest to oldest turns) for i in range(len(context.turns) - 1, -1, -1): turn = context.turns[i] if turn.files: for file_path in turn.files: if file_path not in seen_files: seen_files.add(file_path) file_list.append(file_path) # Newest wins! return file_list ``` **Result**: Tools always see the most recent version of files, preventing outdated content from contaminating analysis. ### Trick 2: The dual prioritization strategy **The challenge**: For optimal token usage, we want newest content first. But for LLM understanding, we want chronological order. **The solution**: Collect newest-first, present chronologically: ```python def build_conversation_history(context: ThreadContext) -> tuple[str, int]: turn_entries = [] total_tokens = 0 # PHASE 1: Collection (newest-first for token budget) for idx in range(len(all_turns) - 1, -1, -1): # BACKWARDS turn = all_turns[idx] if total_tokens + turn_tokens > budget: break # Exclude OLDER turns first turn_entries.append((idx, turn_content)) # PHASE 2: Presentation (chronological for LLM) turn_entries.reverse() # Now oldest-first return format_turns_chronologically(turn_entries) ``` **Result**: Optimal token allocation AND natural conversation flow. ### Trick 3: Early model resolution **The challenge**: Model resolution is expensive and error-prone when done repeatedly. **The solution**: Resolve "auto" mode and validate models once at the MCP boundary: ```python @server.call_tool() async def handle_call_tool(name: str, arguments: dict[str, Any]): # BEFORE tool execution, resolve "auto" to specific model if model_name.lower() == "auto": resolved_model = ModelProviderRegistry.get_preferred_fallback_model(tool_category) arguments["model"] = resolved_model # Validate model availability ONCE provider = ModelProviderRegistry.get_provider_for_model(model_name) if not provider: return early_error_response(f"Model {model_name} not available") return await tool.execute(arguments) ``` **Result**: Single point of failure, consistent resolution, clear error messages. ### Trick 4: Model-specific token allocation **The challenge**: O3 has 200K tokens, Gemini has 1M tokens. How do you allocate efficiently? **The solution**: Adaptive allocation based on model capacity: ```python def calculate_token_allocation(self) -> TokenAllocation: if total_tokens < 300_000: # Smaller models: Conservative, prioritize history content_ratio, response_ratio = 0.6, 0.4 file_ratio, history_ratio = 0.3, 0.5 else: # Larger models: Generous, balanced allocation content_ratio, response_ratio = 0.8, 0.2 file_ratio, history_ratio = 0.4, 0.4 ``` **Examples**: O3 gets 36K for files, 60K for history. Gemini gets 320K for files, 320K for history. ### Trick 5: Provider priority cascade **The challenge**: Not all AI providers are equal in performance and cost. **The solution**: Route through a performance-optimized priority order: ```python PROVIDER_PRIORITY_ORDER = [ ProviderType.GOOGLE, # Direct APIs: Fast, cheap ProviderType.OPENAI, ProviderType.XAI, ProviderType.DIAL, # Unified APIs: More latency ProviderType.CUSTOM, # Local: Privacy, limited ProviderType.OPENROUTER, # Catch-all: Highest latency ] ``` **Result**: Best performance provider is always chosen first, with automatic fallback. ### Trick 6: The "continuation offer" pattern **The challenge**: How do you make cross-tool collaboration feel natural? **The solution**: Every tool response includes a continuation offer: ```python def generate_continuation_offer(self, thread_id: str) -> str: return ( f"💡 **Continue this conversation**: Copy this continuation ID:\n\n" f"`continuation_id={thread_id}`\n\n" f"Example: \"Now review for security\" with continuation_id={thread_id}" ) ``` **User Flow**: analyze → continuation offer → secaudit gets FULL context → seamless handoff. ### Trick 7: Confidence-driven workflow termination **The challenge**: When should workflow tools stop investigating? **The solution**: Progressive confidence tracking with expert validation: ```python def should_continue_investigation(self, request) -> bool: if request.confidence == "certain": return False # Trigger expert analysis return True # Continue investigation # Confidence progression: exploring → low → medium → high → certain → expert validation ``` **Result**: Tools naturally evolve from exploration to certainty with quality control. ### Trick 8: MCP optimization **The challenge**: MCP protocol has transport limits, but internal processing doesn't. **The solution**: Separate transport constraints from internal capabilities: ```python # MCP Transport: Limited to ~960K characters def validate_mcp_request_size(prompt: str) -> bool: return len(prompt) <= MCP_PROMPT_SIZE_LIMIT # Internal Processing: No limits, can handle 1M+ tokens async def call_external_model(enhanced_prompt: str) -> str: # Full context: conversation + files + system prompts return await model_context.provider.generate(enhanced_prompt) ``` **Result**: Rich internal context without transport constraints affecting user experience. ## What we would do differently **1. Memory persistence**: - **Current**: In-memory storage, lost on restart - **Better**: Redis/SQLite persistence with conversation export/import **2. File change detection**: - **Current**: File content may change between conversation turns - **Better**: File hashing to detect changes, automatic re-embedding

Better engineering

I've been staring at my screen for the past hour, watching Cursor AI suggest a database query that's syntactically perfect but will absolutely murder our performance when we have real users. This happens more often than I'd like to admit. The AI follows the patterns correctly, even adds helpful comments. But it doesn't know that this particular table has 50 million rows or that the join it's suggesting will lock up our database for minutes. Everyone's telling us that AI will revolutionize software development. That we'll all be 10x more productive. Maybe they're right about some of that. But honestly? I think we're missing something pretty important in all the hype. ## The thing about better tools Here's what I've learned after using AI coding tools for the past year: better tools don't automatically make you a better craftsperson. Last month, I watched a junior developer work with Claude to build a user authentication system. They were flying through the implementation, getting AI to generate functions, write tests, even create documentation. Pretty impressive setup. But three weeks later? They hit a tricky bug and were completely stuck. Why? Because they'd been delegating work to AI without understanding the context well enough to guide it properly. They hadn't learned the new skills you need when working with agentic coding tools: managing context, breaking down problems, knowing what to delegate and what to keep control of. These are craftsman skills too, just different ones. We're generating more code than ever, shipping features faster than ever, and dealing with more technical debt than ever. Something doesn't add up. ## What actually stays the same Despite all the AI hype, the fundamentals of good software haven't changed at all. Good software is still readable, maintainable, and solves real problems without creating new ones. It still needs to work when things go wrong (and they always go wrong). AI can help you write code faster, but it can't help you understand whether you're solving the right problem. It can't tell you if your architecture will hold up when you have 10x more users. It can't predict that the client will completely change their requirements next month (they will, by the way). I've seen AI generate beautiful functions that do exactly the wrong thing. I've seen it create comprehensive test suites for features that shouldn't exist. I've seen it optimize algorithms that were already fast enough while ignoring actual performance bottlenecks. The problem isn't the AI. The problem is thinking that better tools automatically lead to better outcomes. ## Your job is changing (and that's okay) Look, I'm not going to pretend that AI isn't changing how we work. It absolutely is. But maybe not in the way most people think. You're not going to be replaced by AI. But you might be replaced by someone who knows how to work with AI effectively. The difference is huge. Working with AI effectively means knowing when to trust it and when to ignore it completely. It means understanding what problems it's actually good at solving (spoiler: mostly the boring, repetitive stuff you didn't want to do anyway). It means recognizing when a generated solution is "good enough" and when it's going to cause problems down the line. Most importantly, it means knowing what you're trying to build and why. AI can help you get there faster, but only if you know where "there" is. I've started thinking of AI tools like really smart interns. They're eager to help, they can handle routine tasks pretty well, but they need constant supervision and definitely shouldn't be making important decisions on their own. ## The productivity trap Everyone's obsessed with being more productive these days. Ship faster, code more, deliver earlier. AI is supposed to be the answer to all of this. But here's the thing: most of the problems I see in software projects aren't productivity problems. They're effectiveness problems. Productivity is writing more code per hour. Effectiveness is writing the right code. Productivity is shipping features faster. Effectiveness is shipping features that actually solve problems. AI can definitely help with productivity. It's pretty good at generating boilerplate code, writing tests, and handling routine refactoring. But it's terrible at effectiveness. It can't tell you whether you're building the right thing. I learned this the hard way last year when I used AI to rapidly prototype a feature. The AI helped me build it in half the time it would have taken normally. The client loved the demo. But when we shipped it to real users? Nobody used it. Not because it was buggy, but because it solved a problem that didn't actually exist. That's the difference between being productive and being effective. ## Choose boring solutions (especially with AI) When AI first got really good at coding, I went through a phase where I wanted to use it for everything. Generate functions, write tests, create documentation, optimize performance. It was fun and felt futuristic. Then I realized I was making everything more complicated than it needed to be. AI is great at coming up with clever solutions. It loves design patterns and fancy algorithms and elegant abstractions. But clever isn't always better. Most of the time, boring is better. This applies to the AI tools themselves too. There's a new "revolutionary" coding assistant launching every week. Some promise to be 50% better, others claim to understand your codebase perfectly. I've learned to ignore most of them. We stick with a small, stable set of AI tools and update them monthly, not daily. We're not chasing every new model. We're using the ones that work reliably for the boring stuff we need them to do. I've started using AI mostly for stuff I was already doing in a boring way: generate standard CRUD operations, write basic test cases, create simple utility functions. Let it handle the routine stuff so I can focus on the interesting problems. The interesting problems still need human judgment. They need someone who understands the context, constraints, and trade-offs. AI can help with the implementation, but it can't help with the thinking. ## Details still matter (maybe more now) Here's something weird I've noticed: as AI gets better at generating code, the small details become more important, not less. When everyone can generate a working login system in 10 minutes, the difference between good software and mediocre software comes down to things like error messages, loading states, edge cases, and all the tiny interactions that make software feel polished or clunky. AI is pretty good at the happy path. It's terrible at everything else. It doesn't think about what happens when the network is slow or how the interface should behave when the user does something unexpected. It doesn't anticipate the edge cases that real users will definitely find. But here's the thing: **someone still needs to be there to verify all this stuff.** AI can generate the code, but you need to be the one checking if it actually works in the real world. You need to test those edge cases, review those error states, make sure the generated solution actually solves the problem you have, not the problem the AI thinks you have. That verification work? That's still human work. And honestly, it's the most important human work. ## What this means if you work with us I should probably mention that this isn't just philosophical musing. This is how we actually approach projects at [Dwarves Foundation](https://dwarves.foundation). We use AI tools thoughtfully, as part of a process that still prioritizes human judgment and craft. When you work with us, you get the benefits of AI-assisted development (faster prototyping, fewer routine bugs, more time spent on interesting problems) without the downsides (over-engineered solutions, hidden assumptions, technical debt that shows up later). We'll use AI to generate boilerplate code, but we'll review and refactor it to fit your specific needs. We'll use it to explore different approaches to problems, but we'll make the final architectural decisions based on our experience with real-world systems. Most importantly, we'll stay focused on your actual problems instead of getting distracted by impressive-looking technology that doesn't serve your users. ## Better engineering is still about better judgment I think the biggest misconception about AI and software development is that it's going to make engineering easier. It's not. It's going to make certain parts faster, but the hard parts are still hard. Understanding what to build is still hard. Designing systems that can evolve is still hard. Making trade-offs between different approaches is still hard. Debugging complex interactions is still hard. AI can help with all of these things, but it can't replace the judgment that comes from experience. It can't substitute for understanding your users, your constraints, and your long-term goals. Better engineering in 2025 is still about making good decisions. AI just gives you more information to base those decisions on, and more time to focus on the decisions that matter most. But if I'm being honest, all this talk about judgment sounds pretty abstract. So let me get practical. What does better engineering actually look like when you're working with AI every day? Better output quality, sure. More accurate processes, definitely. But the real differentiator is this: **We know which parts can be automated without compromising quality.** That's the crucial judgment call that separates good engineering teams from great ones. Understanding the boundaries between what should be automated and what needs human craftsmanship. Most teams are still figuring this out. They're either trying to automate everything (weird, over-engineered solutions) or avoiding AI altogether (slower than they need to be). The sweet spot is knowing the difference. At least, that's how we see it. If you're looking for a team that thinks about AI as a tool for better craftsmanship rather than a replacement for it, we should probably talk. The future of software development isn't about humans versus machines. It's about humans and machines working together, with humans still making the important calls.

Why every redesign should start with UX Benchmarking

![](../assets/ux-benchmarking.webp) Redesigns often promise better usability, cleaner visuals, and a fresh take on the product. But without benchmarking the existing experience first, you’re flying blind. You might launch something that *feels* better, only to learn later that task completion rates dropped, frustration rose, and conversion tanked. UX benchmarks aren’t just for data-heavy teams or mature products. They are a minimum standard for making informed, measurable decisions. If you wouldn’t ship code without tests, you shouldn’t ship a redesign without benchmarks. Let’s walk through what UX benchmarking really means, why it matters, how to do it effectively, and how to keep it from limiting innovation. ## What is UX benchmarking? UX benchmarking is the practice of capturing quantitative usability metrics like task success, time on task, error rate, user satisfaction, and more. This establishes a baseline of how your product performs today. Think of it as a UX snapshot. It’s not a score to chase but a reference point. It gives you a way to measure if your new design actually improves the experience or if you’re just shifting pixels around. In a redesign, that matters. Baselines let you compare before and after in a structured way. ## Why it matters before a redesign ### 1. Avoid accidental regression Without a baseline, there’s no way to tell if the redesign improved or worsened the experience. A cleaner UI might look better but perform worse. Benchmarks catch that before it reaches production. ### 2. Focus on what actually needs fixing Benchmarks reveal the real pain points. Instead of guessing, teams prioritize what impacts usability the most—whether it’s a broken flow or a confusing form. ### 3. Prove ROI Before-and-after benchmarks let you quantify improvement. If task success jumps from 70% to 92%, that’s concrete progress you can share with the team and leadership. ### 4. Build stakeholder confidence Data earns trust. Benchmarks give product and business teams a clear view of how design contributes to outcomes like retention, activation, or support reduction. ### 5. Prevent redesign theater Redesigns done for visual polish or internal tastes often miss the mark. Benchmarks help teams stay outcome-driven, not aesthetics-driven. ### 6. Watch for metric misuse According to Campbell’s Law, when a metric becomes a target, it can lose its value. Inflated success rates or simplified tasks can look good on paper but misrepresent real usability. Benchmarks need to be honest, not gamed. ### 7. Don’t confuse structure with constraint Some fear benchmarks kill creativity. In reality, they give you guardrails, not handcuffs. You can still push bold ideas—just measure if they actually work. ## How to benchmark UX effectively ### Choose the right metrics - **Effectiveness:** Can users complete the task - **Efficiency:** How long does it take them - **Satisfaction:** How do they rate the experience (SUS, SEQ, NPS) - **Errors:** Where do they stumble - **Engagement:** How deep or far do they go in the task ### Pick your benchmarking method - **Internal benchmarking:** Measure your product now and again post-redesign - **Competitive benchmarking:** Test your product against similar ones in your category - **Best-in-class benchmarking:** Compare yourself to UX leaders outside your industry to raise the bar ### Focus on real, high-value tasks Don’t benchmark a feature no one uses. Choose representative tasks that reflect critical user journeys like onboarding, checkout, or account setup. ### Keep testing consistent Use the same user profiles, environment, and tasks. That way, comparisons are clean and improvements are clear. ### Pair quant with qual A task success rate of 60% tells you something is wrong. Watching users struggle with the form tells you why. Metrics are vital, but so is observing behavior and listening to feedback. ### **Example: benchmarking in a fintech product** A fintech startup wants to validate its crypto trading flow. Before launch, designers link a Figma prototype to Maze. The results: - 60% task success rate - Multiple misclicks on the trading form - Average SUS score of 65 out of 100, indicating low usability - Time-on-task data shows even successful users hesitated at the fee disclosure step The team iterates the design. Post-launch, they use Mixpanel to track the trading funnel. They discover 20% of users drop off at the “confirm trade” step. Hotjar recordings show confusion over a vague fee disclosure. User surveys confirm the issue. Several users rate the experience 3 out of 10, saying “didn’t understand fee structure.” They fix the UI in Figma and retest in Maze. This time, 90% succeed, SUS jumps to 80, and time-on-task improves as users move through the flow with less hesitation. To sustain visibility, they set up a live UX dashboard: - Mixpanel tracks funnel conversion and retention - Quarterly NPS surveys (via Qualtrics) measure sentiment This mix of task-based testing, behavioral data, and long-term metrics gives the team a full picture. It covers both usability and long-term user loyalty. ## Conclusion Redesigning without benchmarks is like painting in the dark. You might hit the mark, but more often, you’ll miss and never realize it. Benchmarks don’t slow you down. They give you a map. They keep the team focused on the right problems, protect you from regression, and help prove the value of good design. Innovation still matters. But it has to work. And the only way to know that is to measure it. So before your next redesign kicks off, pause, measure, and get your baseline. Then go build better. ## Learn more Explore these original articles and guides for a deeper understanding of UX benchmarking: - [**Product UX Benchmarks – Nielsen Norman Group**](https://www.nngroup.com/articles/product-ux-benchmarks/) The core guide on types of benchmarks, metrics to track, and how to run UX benchmark studies - [**Benchmarking UX: Tracking Metrics – Nielsen Norman Group**](https://www.nngroup.com/articles/benchmarking-ux/) Practical overview covering when and why to benchmark, and how to interpret your results - [**Quantifying UX Improvements: A Case Study – Nielsen Norman Group**](https://www.nngroup.com/articles/quantifying-case-study/) Real-world example of tracking UX metrics over time and measuring impact - [**Campbell’s Law: The Dark Side of Metric Fixation – Nielsen Norman Group**](https://www.nngroup.com/articles/campbells-law/) Explains how misuse of metrics can distort design decisions and harm user experience - [**Build a UX Benchmarking Program: Two Approaches – AnswerLab**](https://www.answerlab.com/insights/ux-benchmarking-program-two-approaches) Advice for small teams on creating and scaling a UX benchmarking practice

LSTM

Long short-term memory (LSTM) networks represent a significant leap forward for anyone working with sequential data. If you have ever tried to train a basic recurrent neural network (RNN) and found it struggled to learn patterns over longer sequences, you are not alone. The primary challenge? Exploding and vanishing gradients. These issues make it tough for standard RNNs to recall events from more than a few steps ago. LSTM changes the game by introducing a clever architecture that separates long-term memory from short-term memory. Instead of relying on a single feedback loop, LSTM networks use two distinct paths. One path, the cell state, is designed to hold onto information for the long haul. The other, the hidden state, manages details that only matter in the moment. This separation allows LSTMs to remember important events from much earlier in a sequence. Think of it as having both a notebook for key ideas and a sticky note for quick reminders. At the heart of every LSTM unit are three gates: - **Forget gate:** This gate decides what information to keep and what to discard from long-term memory. If something is no longer relevant, it gets filtered out. - **Input gate:** This determines how much new information should be added to the long-term memory. It is where the network learns what is worth remembering. - **Output gate:** This controls what information gets passed along as the short-term memory, influencing the network’s immediate output. These gates utilize two activation functions: sigmoid (which outputs values between 0 and 1, acting like a probability or percentage) and tanh (which outputs values between -1 and 1, allowing the network to represent a range of information). By combining these, LSTM networks can fine-tune what they remember, update, or ignore at every step. One of the best aspects of LSTM networks is their flexibility. You can unroll them over sequences of any length, and they will use the same weights and biases each time. This means you do not have to redesign your network for every new dataset. LSTM adapts to the data, not the other way around. If you are working with time series, language data, or any sequence where context from earlier steps matters, LSTM should be on your shortlist. It is a practical, well-crafted approach that helps your models remember what actually matters, without getting tripped up by technical limitations. Sources: - -

Breakdown

We believe that true understanding comes from building things ourselves. If we cannot recreate something, we probably do not understand it as well as we think. This principle shapes how we approach technology and learning across our woodland. LLMs have changed the way we explore, document, and share technical knowledge. They have made it possible to dive deeper and faster into the inner workings of software, systems, and tools. Still, knowing how something works is more than just reading about it. It is about taking it apart, seeing what makes it tick, and sometimes putting it back together in new ways. Our `/topics` folder is where we collect our learnings on specific concepts and technologies. But this series goes further. In "Breakdown", we focus on the nuts and bolts of real applications. We break down: - What the app does - How it works under the hood - The data structures and algorithms it uses (or what objects it creates, reads, updates, and deletes) - The technical challenges it faces and how those are solved - Any clever tricks or tips we discover along the way This is not the place for business case studies or market analysis. Here, we care about the craft, the code, and the solutions that power the tools we use every day. ## What you can expect Each article in this series is a deep dive into the technical side of a real-world application. We will explain the big picture, but we will not shy away from the details. Expect diagrams, code snippets, and honest takes on what is hard, what is smart, and what we would do differently.

Composing the Dwarves video pipeline

We care about doing things right and having a bit of fun along the way. Our new video pipeline is built to help us tell better stories, faster. Whether it’s a deep tech explainer or a meme with bite, every piece now flows through a system that keeps us sharp and in sync. ## Why build a video pipeline? Because we want our videos to sound like us: clear, clever, and just the right amount of weird. Instead of cobbling things together every time, we built a flow. So the team can focus on the good stuff like ideas, stories, and the occasional perfectly timed troll without getting bogged down. ![](assets/compose-video-pipeline.png) ## Long form video workflow: detailed steps and tools **Target channels:** YouTube, LinkedIn **Use case:** Explainers, dev logs, research stories, design walkthroughs ### Draft the script *Tool: Notion* We start with a clear requirement: - What are we trying to explain and the message? - Who’s it for? - Any references we admire? This becomes the draft script. Everyone chimes in until the script hits the right tone: smart, simple, not boring, aligned with how we talk as engineers. ### Generate the script *Tool: Generative AI* We write or co-write the video script using LLMs to help reshape ideas from memos, meetings, or chat threads into a clear voiceover-ready script. The goal is to make the message clear and structured, keeping it aligned with how we’d speak as builders. Think of this as refactoring written insight into spoken form. ### Choose the reader voice *Tool: ElevenLabs, Google AI Studio or a Dwarves voice* Sometimes it’s a Dwarves teammate. Sometimes it’s AI from Elevenlabs. Either way, the voice should match the vibe: grounded, calm, witty, a little smug (in a good way), never robotic. ![](assets/compose-video-elevenlabs.png) ### Add transcript *Tool: Capcut* We pull a clean transcript for captions. Captions help with clarity, accessibility, repurposing and easier to clip down later. Makes sure keep it clean and time-synced. ### Gather visuals *Tools: Figma, Google, Meme Kitchen, Giphy, Reddit community* We source or create visuals to match the story, diagrams, code snippets, product screenshots, doodles, or memes. Rule of thumb: visuals should add clarity, not just decoration. ![](assets/compose-video-capcut.png) ### Edit and output production video *Tool: Capcut desktop* Capcut handles most of our editing from syncing visuals and audio to adding subtitles, transitions, and some flair. Final output: 1080p, platform-ready title and description. ## Short video workflow Shorts are where we get to mess around. Memes, quick hits, highlights whatever gets the point across in under a minute. **Target channels:** YouTube shorts, Instagram reels, Facebook reels **Use case:** 1-minute tips, memes, or repurposed long-form content - **Script**: Notion & Generative AI - **Visuals**: Giphy, Canva, Reddit community, Google - **Edit**: Capcut (desktop or phone) - **Post**: Native apps (YouTube shorts, IG reels, Facebook reels) ### Two ways to make Shorts **Scripted short formats** - “Dad, how do I?” explainer style - “1-Minute Crafts” for dev/design tools - Quick intros to internal tools or team practices **Cut from long-form** - Pull 1–3 highlights from a longer video - Add captions or transcript overlay - Export as Shorts-ready clip ## Support layer (behind the scenes) - **Where do we store things?** - All assets (scripts, audio, visuals, exports) go into Google Drive. - Organized by episode or series folder. - Notion Content calendar is used for asset tracking and version control. - **How do we notify the team?** - Use Dwarves discord when the draft is ready. - Feedback and final review tracked at internal channel. - Tag stakeholders for final sign-off. - **How are credentials managed?** - Platform credentials (YouTube, LinkedIn) are managed by the content lead. - Access is shared only with designated team members. - Credential list reviewed and rotated quarterly. ## Script for short teel: “AI-agent explained” example [Opening image: Three stacked icons labeled 1, 2, 3 with “AI Levels”] Voiceover: Let’s talk AI agents. Not every AI is created equal. Most people call everything “AI” but there are three levels, and only one of them is actually doing your job for you. [Cut to: LLM icon, chat bubble] Level one: Large language models. These are your classic ChatGPTs. They wait for your prompt, spit out text, and never touch your stuff unless you say so. Basically, a smart parrot with a keyboard. [Cut to: Workflow diagram, gears turning] Level two: AI workflows. Now you’ve got automation. You design the steps, AI follows your recipe, and everything is nice and predictable. If you want a robot intern who never goes off-script, this is your stop. [Cut to: Agent icon, branching paths, goal flag] Level three: AI agents. Here’s where the magic (and chaos) happens. The AI decides what to do, judges its own work, and keeps trying until it gets the result. It’s like hiring a junior dev who never sleeps and sometimes invents whole new bugs. [Cut to: Meme “I let the agent handle it, now I have no idea what’s running in prod”] Sure, it feels like the future. But if you’re still making all the decisions, you’re not using an agent, you’re just automating. [Closing image: Giphy sticky note “Let the agent vibe, but check the logs”] So, want to level up? Let the AI make the calls, but don’t blame us when it starts refactoring your life. ## Final notes This pipeline is how we turn working knowledge into visual stories. It’s how we build our public memory, just like our memo. Stick to the system. Improve where needed. And ship it when it’s clear, not when it’s perfect.

Modernizing complex financial systems through systematic transition

**Industry** Financial Services, Securities Trading **Location** Southeast Asia **Business context** A tech-driven financial services firm serving retail and institutional clients across Southeast Asia. **Solution** We deployed developers to work alongside their core team on system documentation and workflow optimization. **Outcome** Successfully integrated with their team, delivering improved documentation and streamlined development processes. **Our services** System Audit, Development Operations, Technical Architecture, Documentation Engineering ## Technical highlights - **System reverse engineering**: Comprehensive documentation of legacy architecture and workflows to enable smooth team transitions - **Zero-downtime transition**: Carefully orchestrated handover process maintaining critical trading operations - **Architecture mapping**: Detailed analysis of system components, dependencies, and infrastructure - **Workflow optimization**: Introduction of structured development processes improving team efficiency - **Platform integration**: High-speed integration with new platforms based on evolving business requirements - **Technical partnership**: Active involvement in architectural decisions and long-term technology strategy ## What we did The client approached us with a critical challenge: their trading platform had evolved into a highly complex system that was becoming increasingly difficult to maintain and extend. As a technology-driven financial services firm, they recognized that their competitive advantage depended on their ability to rapidly adapt their platform to market needs and regulatory requirements. The platform's complexity stemmed from years of organic growth, integrating various trading systems, risk management tools, and third-party services. While this approach had served them well, it created significant technical debt and made it challenging to onboard new development teams or implement new features quickly. > **Core Challenge**: The client needed a partner who could not only understand their complex legacy system but also modernize it without disrupting the critical daily operations that thousands of traders depended on. We worked directly with their leadership, product, and operations teams to develop a systematic approach to supporting their development efforts. Our goal was to establish ourselves as an extension of their team while bringing modern development practices and architectural improvements to their platform. ![](assets/kafi-site.webp) ## The challenges faced The trading platform presented several interconnected challenges that required careful navigation: ### Technical complexity without documentation - **Undocumented architecture**: Years of development had created a system where knowledge existed primarily in the minds of long-term developers - **Hidden dependencies**: Critical system interactions weren't mapped, making changes risky - **Technical debt accumulation**: Quick fixes and workarounds had compounded over time - **Knowledge silos**: Different teams held pieces of the system understanding with no unified view ### Operational criticality - **Zero tolerance for downtime**: The platform processed millions in daily transactions - **Real-time requirements**: Trading systems demand microsecond-level performance - **Regulatory compliance**: Financial regulations required careful handling of any system changes - **24/7 operations**: Market hours and global trading meant limited maintenance windows ### Growth constraints - **Scaling difficulties**: Adding new features or integrations took increasingly longer - **Resource limitations**: Difficulty onboarding new developers due to system complexity - **Business agility**: Rapid market changes required faster platform evolution - **Future-proofing needs**: Plans for expansion required a more flexible architecture These challenges created a situation where their technical capabilities were becoming a bottleneck to business growth, despite their strong market position and tech-driven approach. ## How we built it Our approach to supporting the platform modernization centered on **systematic transition and knowledge transfer** while maintaining operational stability. We developed a three-phase strategy that allowed us to gradually assume development responsibilities without disrupting critical trading operations. ![](assets/kafi-app.webp) ### Phase 1: Comprehensive system audit We began with an intensive audit to understand the full scope of their technology landscape: - **Architecture mapping**: Created detailed diagrams of system components and their interactions - **Code analysis**: Reviewed millions of lines of code to identify patterns, dependencies, and risk areas - **Infrastructure assessment**: Documented deployment processes, server configurations, and scaling mechanisms - **Workflow documentation**: Mapped existing development and operational procedures ### Phase 2: Gradual transition and knowledge transfer With a clear understanding of the system, we implemented a carefully orchestrated transition: - **Parallel operations**: Our team worked alongside their developers for seamless knowledge transfer - **Incremental responsibility**: Started with non-critical components before moving to core systems - **Documentation creation**: Built comprehensive technical documentation as we learned each subsystem - **Process establishment**: Introduced structured development workflows without disrupting existing operations > **Key Innovation**: We developed a **"shadow development" approach** where our team would first observe, then assist, and finally support development efforts for each system component. This ensured zero disruption while building confidence on both sides. ### Phase 3: Modernization and extension Once established as supporting the development team, we began systematic improvements: - **Technical debt reduction**: Refactored critical components while maintaining functionality - **Integration acceleration**: Built frameworks for rapid integration with new platforms - **Performance optimization**: Improved system response times for critical trading operations - **Monitoring enhancement**: Implemented comprehensive observability for proactive issue detection ## What we achieved Our partnership delivered transformative results across technical, operational, and strategic dimensions: ### Technical transformation - **Comprehensive system documentation**: Created detailed technical documentation covering architecture, workflows, and business logic that previously existed only as tribal knowledge - **Reduced onboarding time**: New developers can now become productive in weeks rather than months - **Improved system stability**: Proactive monitoring and structured processes reduced critical incidents - **Accelerated delivery**: Integration with new platforms now measured in days rather than weeks ### Operational excellence - **50–60% development support**: Dwarves Foundation successfully supports majority of platform development activities - **Zero-downtime transition**: Completed the entire transition without a single trading disruption - **Structured workflows**: Introduced development practices that improved team efficiency and code quality - **Knowledge continuity**: Eliminated single points of failure through comprehensive documentation ### Strategic partnership - **Technical decision-making**: Became actively involved in architectural and technology strategy decisions - **Future-ready platform**: Positioned their system for planned expansions and new business initiatives - **Risk mitigation**: Detailed system health reports identified and addressed potential issues proactively > **Client Impact**: "The team didn't just support our development – they transformed how we think about and manage our technology platform. They've become an integral part of our technical strategy." Our work demonstrates how systematic approaches to legacy system modernization can unlock business potential while maintaining operational stability. By combining deep technical expertise with careful transition planning, we helped transform their complex platform from a constraint into a competitive advantage. The partnership continues to evolve, with our team now supporting their technology operations and actively shaping their platform's future. This case study exemplifies how thoughtful technical partnerships can enable financial services firms to maintain their edge in rapidly evolving markets.

Should AI agents transact without human confirmation?

![](../assets/autonomy-automation.webp) ## What's the deal with agentic AI? Agentic AI can automate tasks, save time, and simplify interactions. But what happens when machines act without asking? Agentic AI systems, like Visa’s Intelligent Commerce, Google Pay’s AI Mode, and Coinbase’s x402, independently perform tasks on users' behalf. They streamline processes but raise important UX questions around user control. Here’s how to integrate agentic AI without compromising user autonomy. ## Benefits worth leveraging These are use cases where agentic AI clearly helps. Think convenience, access, and scaling repetitive work. ### Automate simple, repetitive tasks Let AI take over low-stakes, routine tasks to reduce friction. [Google Pay](https://techcrunch.com/2025/05/20/google-adds-ai-powered-shopping-features-for-discovery-and-easy-check-out/) automatically tracks product prices and makes small purchases when prices drop, reducing user effort in managing regular transactions. ### Improve accessibility AI can simplify digital experiences for users facing cognitive, visual, or process-related barriers. [Visa’s Intelligent Commerce](https://corporate.visa.com/en/products/intelligent-commerce.html) uses AI to securely automate purchases within preset spending limits, helping users overwhelmed by traditional checkout complexities. ### Efficient microtransactions Good for systems that need to handle lots of tiny transactions with minimal friction. [Coinbase’s x402 protocol](https://www.coinbase.com/developer-platform/discover/launches/x402) enables AI agents to handle internet micropayments automatically, ideal for content subscriptions and small service fees. ## Key UX risks and practical solutions When done wrong, agentic AI erodes trust, frustrates users, and takes away control. Here’s how to avoid that. ### Maintain user autonomy Don’t design out the user. People still want a say, especially with money. **Actionable tip:** Insert explicit consent checkpoints for critical transactions. **Insight:** Clear decision points reinforce autonomy. When users understand when and why a decision is being made, and feel like they had a part in it, they are more likely to trust the system. This aligns with the psychological principle of autonomy outlined by the [Nielsen Norman Group](https://www.nngroup.com/articles/autonomy-relatedness-competence/). ### Prevent financial anxiety Unexpected charges or unclear automation can make users feel unsafe. **Actionable tip:** Allow users to set explicit spending limits easily. **Insight:** [In a recent survey](https://www.pymnts.com/personal-finance/2025/financial-anxiety-spurs-demand-for-consumer-budgeting-apps/), 66% of U.S. shoppers said they would not allow AI to make purchases for them, even if it saved money. This distrust isn’t about laziness. It’s rooted in concern that AI might prioritize business goals over user interests. Clear boundaries and manual approvals help mitigate that. ### Reduce consent fatigue Over-notifying is as bad as under-notifying. Striking the right balance matters. **Actionable tip:** Employ adaptive consent, prompting users strategically. **Example:** [SecurePrivacy](https://secureprivacy.ai/blog/adaptive-consent-frequency-using-ai-to-combat-consent-fatigue)’s adaptive consent model uses AI to show consent prompts only when users are most receptive, effectively balancing compliance with user experience. ## Proven frameworks for user-centric AI These patterns help teams preserve autonomy while delivering intelligent systems. ### Advocate for user control Design AI that users can manage directly, not platforms. **Example:** Auto-GPT and BabyAGI are open-source AI platforms that let users directly control and monitor their AI, enhancing transparency and reducing manipulation risks [Explore Auto-GPT](https://github.com/Significant-Gravitas/AutoGPT), [Explore BabyAGI](https://github.com/yoheinakajima/babyagi). **Career insight:** Expertise in open-source tools boosts your ability to advocate for responsible UX. ### Establish trusted autonomy Bake in structure and oversight. Systems should always have fallback control. **Example:** Visa’s Intelligent Commerce explicitly sets automated spending limits and requires human approval for transactions beyond certain thresholds, ensuring clear oversight and user trust [Read more](https://venturebeat.com/ai/visa-launches-intelligent-commerce-platform-letting-ai-agents-swipe-your-card-safely-it-says/). ### Adopt progressive disclosure Let users ease into automation. Start small, and grow trust. **Example:** Google Pay incrementally introduces automated features, allowing users to comfortably transition to greater levels of autonomy while always retaining manual override options [Read more](https://techcrunch.com/2025/05/20/google-adds-ai-powered-shopping-features-for-discovery-and-easy-check-out/). ## Actionable UX takeaways - Automate only low-risk, repetitive tasks where consequences are minimal and expectations are clear. - Explain how and why the AI made a decision in simple terms users can easily understand. - Use smart prompts that appear only when users are likely to engage, not every time something changes. ## Bottom line Agentic AI isn’t the problem. Poor implementation is. The way forward is to combine intelligent automation with user oversight. Build AI systems that enhance decision-making rather than bypass it. Help users stay in control, understand what’s happening, and make corrections when needed. That’s how you keep trust intact while delivering smart experiences.

Monitoring

To ensure the operational reliability of our **memo.d.foundation**, we have developed a comprehensive, dual-mode monitoring system that combines proactive **synthetic monitoring** with reactive **instrumental alerts**. This integrated strategy provides complete visibility into platform health, from business metrics to real-time system events. ## Key benefits of our dual-mode approach Our hybrid monitoring strategy delivers significant operational advantages by addressing the limitations of traditional single-method systems: - **Proactive and reactive coverage**: We combine scheduled "scout" checks for landscape-level health with event-driven "messenger" alerts for immediate issue notification, eliminating visibility gaps. - **Early issue detection**: Synthetic monitoring identifies potential data quality or pipeline bottlenecks before they impact user experience or downstream processes. - **Real-Time event awareness**: Instrumental monitoring provides immediate feedback on critical events, such as NFT mints and CI/CD pipeline status, enabling rapid engineering response. - **End-to-end data integrity**: Our checks span the entire data lifecycle, from Markdown content ingestion and **Parquet** file health to database consistency and AI embedding generation. ![memo-monitoring](assets/memo-monitoring.webp) ### Proactive health audits: Synthetic monitoring Our synthetic monitoring platform operates on a fixed schedule, executing a series of checks against our core data assets and business logic. It serves as our early warning system, providing a regular pulse on the health of the entire **memo.d.foundation** system and catching issues before they escalate. #### NFT system reporting (`memo-nft-report.ts`) This daily report provides a comprehensive overview of our minting pipeline and NFT collection activity. It leverages **DuckDB** to execute federated queries across both our canonical **Parquet** vault and our production **PostgreSQL** database, unifying disparate data sources into a single, coherent view. **Federated data integration:** The system joins data from a remote Parquet file and a PostgreSQL table to generate a holistic report. ```typescript // Dual-source data integration with DuckDB const vaultMetrics = await connection.runAndReadAll(` SELECT COUNT(CASE WHEN should_mint = true THEN 1 END) as mintable_total, COUNT(CASE WHEN should_mint = true AND minted_at IS NOT NULL THEN 1 END) as minted_count FROM read_parquet('https://memo.d.foundation/db/vault.parquet') `); const collectionMetrics = await connection.runAndReadAll(` SELECT COUNT(*) as total_events, SUM(amount) as total_collected FROM memo_nft_db.memo_nft.memo_minted_events `); ``` This daily audit, running via a `cron` schedule in **GitHub Actions**, tracks key performance indicators, including: - **Minting pipeline health**: Monitors success rates, queue depth, and pending content. - **Collection activity**: Analyzes total collection events, revenue, and unique collectors. - **Author and content Trends**: Identifies top contributors and popular content tags. #### Data vault integrity (`monitor-vault-parquet.ts`) This check is designed to verify the completeness and quality of our core knowledge vault. It provides a quick, color-coded health status that allows us to assess data integrity at a glance. **Data quality metrics:** Our script assesses the vault based on a predefined set of quality metrics. ```typescript interface VaultMetrics { totalRecords: number; missingDates: number; missingAuthors: number; missingEmbeddings: number; pendingMint: number; pendingArweave: number; } ``` ![memo-monitoring-1](assets/memo-monitoring-1.png) **Health status logic:** The system uses tiered thresholds to classify the vault's health, ensuring we prioritize critical issues effectively. ```typescript const hasWarnings = metrics.missingDatesPercent > 25 || metrics.missingAuthorsPercent > 40; const hasCritical = metrics.pendingMint > 20 || metrics.missingEmbeddings > 100; const healthStatus = hasCritical ? '🔴 Critical' : hasWarnings ? '🟡 Warning' : '🟢 Healthy'; ``` This provides **actionable insights** by immediately flagging which specific metrics have crossed their warning or critical thresholds, enabling focused remediation. ### Real-time event notifications: Instrumental monitoring Where synthetic monitoring is proactive, our instrumental monitoring is reactive. It operates across several integration layers to provide immediate notifications based on specific system events. #### NFT minting alerts When a new article is successfully minted as an NFT, our `notify-discord-minted-articles.ts` script is triggered. This process handles community communication by sending a rich, formatted Discord notification. We leverage the **Model Context Protocol (MCP)** to generate context-aware messages that are more informative and engaging than standard text. **MCP Integration for rich notifications:** ```typescript await mcpDiscord.callTool({ name: "discord-send-embed", arguments: { username: "Memo NFT", webhookUrl: process.env.DISCORD_WEBHOOK_URL, content: generatedMessage, title: "📢 New notes minted in the Memo", autoFormat: true, } }); ``` This system ensures both optimal performance and high reliability through: - **Connection resilience**: Implements a retry mechanism for establishing the initial connection. - **Exponential backoff**: If a notification fails, the system waits progressively longer before retrying, preventing API rate-limiting issues. - **Graceful error handling**: Failures are logged without crashing the parent workflow. ![memo-monitoring-2](assets/memo-monitoring-2.png) #### CI/CD workflow monitoring We have integrated instrumental monitoring directly into our **GitHub Actions** workflows. This provides real-time status updates on deployments and other critical automated processes, sending success or failure notifications to a dedicated Discord channel. **Standardized notification steps:** ```yaml - name: Notify Discord on Success if: success() uses: sarisia/actions-status-discord@v1 with: webhook: ${{ secrets.DISCORD_WEBHOOK_URL }} title: '✅ Deployment Completed Successfully' color: 0x00ff00 - name: Notify Discord on Failure if: failure() uses: sarisia/actions-status-discord@v1 with: webhook: ${{ secrets.DISCORD_WEBHOOK_URL }} title: '❌ Deployment Failed' description: 'Please check workflow logs for details.' color: 0xff0000 ``` ### System architecture and implementation Our monitoring platform is built on a modern, flexible technology stack chosen for its performance, ease of integration, and alignment with our team's expertise. #### The DuckDB analytics engine We selected **DuckDB** as our core data processing engine due to its unique capabilities for in-process analytics. It allows us to perform complex analytical queries on local and remote data sources without the overhead of a traditional data warehouse. **Key advantages:** - **Federated queries**: Natively queries remote Parquet files and connects to our live **PostgreSQL** database in a single session. - **High performance**: Columnar-vectorized query execution is highly optimized for analytical workloads. - **Zero-dependency**: Runs entirely in-memory, simplifying our CI/CD environment setup. **PostgreSQL integration:** The connection process involves loading the `postgres` extension and attaching our remote database as a read-only source. ```typescript async function setupDuckDBConnections(): Promise { const instance = await DuckDBInstance.create(':memory:'); const connection = await instance.connect(); // Load extensions and attach remote database await connection.runAndReadAll('LOAD postgres;'); await connection.runAndReadAll(` ATTACH '${process.env.DB_CONNECTION_STRING}' AS memo_nft_db (TYPE postgres, READ_ONLY); `); return connection; } ``` ### Security and data handling We built our monitoring system with security and responsible data handling as core principles: - **Secure credentials management**: All credentials, such as API keys and database strings, are managed as **GitHub Secrets**. Access is limited by the **principle of least privilege**, and our services connect using a dedicated **read-only** database user to prevent accidental data modification. - **Privacy by design**: We practice **data minimization** in all public-facing reports to protect community privacy. For instance, collector wallet addresses are truncated to show activity trends without revealing full identities. ```typescript // Address truncation for privacy const truncatedAddress = String(row.address || '').substring(0, 8) + '...'; ``` ### Success metrics We track a set of key performance indicators to measure the effectiveness of our monitoring infrastructure: - **Monitoring with Uptime**: Targeting 99.9% uptime for all monitoring services, ensuring continuous visibility. - **Alert latency**: Average delivery time for critical alerts is under 2 minutes. - **Data freshness**: Reports leverage data that is never more than 6 hours old. - **Query performance**: Complex analytical reports complete in under 30 seconds. ### What's next? While the current work provides a solid foundation, we have several enhancements planned to further improve our monitoring capabilities: - **Automated remediation**: For common, well-understood issues, we will explore self-healing capabilities to reduce manual intervention. - **Executive dashboards**: We will create higher-level dashboards that distill technical metrics into clear business insights for leadership.

Attack their cash cow

**The most effective way to disrupt established players is to attack their most profitable business practices.** Counter-positioning isn't about competing head-to-head, it's about creating a business model that forces incumbents to choose between copying you and protecting their existing revenue streams. When done right, they can't do both. This strategy explains why Netflix killed Blockbuster, why Square disrupted traditional payment processors, and why challenger banks are winning market share from traditional institutions. The pattern is consistent: find what competitors can't afford to give up, then give it away or do it better. ## Why incumbents freeze Established companies struggle with counter-positioning because **their greatest strengths become their biggest weaknesses**. Three factors create this paralysis: **Short-term profit pressure:** Public companies face quarterly earnings expectations. Abandoning profitable practices for long-term positioning often conflicts with immediate shareholder demands. **Entrenched thinking:** Success creates mental models that resist change. When your transfer fees generate millions in revenue, eliminating them feels like business suicide. **Principal-agent problems:** Professional managers optimize for personal career safety rather than company transformation. Disrupting your own cash cow is risky, protecting it feels safer. ## The disruption playbook **Target the profit engine:** Successful counter-positioning identifies what incumbents rely on most for revenue, then offers that same value through a different model. Netflix understood that Blockbuster's late fees generated massive profits but created customer pain. Their subscription model eliminated late fees entirely, forcing Blockbuster to choose between their cash cow and customer satisfaction. Square gave away card readers and simplified software when traditional processors charged hundreds for hardware and complex monthly fees. Payments companies couldn't match this without destroying their existing revenue model. Techcombank eliminated transfer fees in Vietnam's banking market. While other banks generated substantial revenue from these fees, Techcombank sacrificed short-term income for market share growth. Traditional banks eventually followed, but too slowly. **Move fast before adaptation:** Counter-positioning works because **incumbents need time to restructure their business models**. This window allows disruptors to build market position and customer loyalty. ## Pattern recognition The most successful counter-positioning attacks share common characteristics: **Customer pain becomes competitive advantage:** Every cash cow creates customer friction. Late fees annoy movie renters. Transfer fees frustrate bank customers. Complex payment setups burden small businesses. **Structural inability to respond:** Incumbents aren't just slow to respond, they're often unable to respond without fundamental business model changes. **Word-of-mouth acceleration:** When your model genuinely improves customer experience, organic growth amplifies your market penetration before competitors can react. ## Implementation strategy **For disruptors:** Research where established players extract the most profit while creating customer pain. Build your model around eliminating that friction, even if it means sacrificing immediate revenue. Dyson attacked the disposable vacuum bag industry by creating bagless technology. Vanguard eliminated high mutual fund fees through index investing. Robinhood removed trading commissions when established brokers relied on them. **For incumbents:** Create independent teams specifically tasked with cannibalizing your existing business. Don't integrate these efforts with existing operations, their incentives will always favor protecting current revenue. **Leadership requirement:** Counter-positioning typically requires founder-CEOs or leaders with significant influence. Professional managers rarely have the authority or motivation to "shoot themselves in the foot" proactively. ## The timing advantage **Counter-positioning works best in industries where incumbents are "addicted" to specific revenue streams.** Look for markets where established players have become dependent on practices that create customer friction. Traditional industries with embedded profit mechanisms, regulatory protections, or complex legacy systems often provide the best opportunities. The key is moving fast enough to establish market position before incumbents can restructure. As markets mature and customer expectations evolve, counter-positioning becomes more powerful. Customers increasingly choose convenience and value over brand recognition. Digital tools make it easier for smaller players to deliver superior experiences. **The lesson is clear:** If you don't cannibalize your own business model, someone else will. The companies that survive disruption are those willing to abandon profitable practices before competitors force them to. *Note: Counter-positioning analysis draws from Hamilton Helmer's "7 Powers" framework and Clayton Christensen's "Innovator's Dilemma," combined with case studies from financial services, technology, and retail disruption patterns.*

Communication overhead in the agentic era

How much time do you spend explaining tasks versus the time spent executing them? When did you last spend 30 minutes briefing a 10-minute task, only to receive work that missed the mark? This reveals a growing reality: **communication overhead often exceeds task execution time.** As AI agents handle routine work with minimal explanation, the inefficiency of human delegation becomes stark. Sometimes, the cost of communicating with humans outweighs their cognitive advantages. ## The delegation math is clear **AI agents complete routine tasks 3-5x faster than human delegation cycles.** The time breakdown reveals the true cost of communication overhead: | Phase | Human Delegation | AI Delegation | |-------|------------------|---------------| | **Setup** | 20-40 min explaining | 5-10 min prompting | | **Execution** | 2-4 hours work | 10-30 min execution | | **Review** | 30-60 min clarification | 15-30 min refinement | | **Rework** | 1-3 hours iterations | Minimal rework | | **Total** | **3-4+ hours** | **45-70 minutes** | This pattern spans functions. Marketing teams spend hours briefing copywriters for social posts that AI generates in minutes. Operations managers explain day-long data analysis that AI completes in under an hour. ## Why human delegation creates friction **Explanation overhead exceeds execution time.** A marketing manager explaining competitor analysis spends 45 minutes covering context and methodology. The analysis takes 2 hours. An AI agent produces comparable analysis in 20 minutes. **Question anxiety produces wrong outputs.** Employees hesitate to ask clarifying questions due to time pressure or fear of appearing incompetent. They make assumptions instead, creating blog posts for wrong audiences or using outdated methodologies. **Context switching breaks momentum.** Humans juggle multiple priorities and need 15-30 minutes to refocus on tasks. AI agents don't context-switch or have competing priorities. ## Where AI agents dominate **Content creation and analysis** see dramatic improvements. Writing job descriptions, analyzing survey data, or generating customer support responses happen faster with AI than with human writers who need extensive briefing. **Data processing and research** benefit from AI's speed. Analyzing spreadsheets, researching market trends, or compiling competitive intelligence happen in minutes rather than hours. **Process documentation** works well with AI delegation. Agents quickly create procedures, update policies, or generate compliance reports that humans then review. ## When humans remain essential **Strategic and relationship work requires human judgment.** Client negotiations, team conflict resolution, and business strategy need emotional intelligence that AI agents lack. Senior managers and salespeople create value that justifies communication time. **Complex problem-solving benefits from human experience.** Debugging operational issues, resolving complaints, or diagnosing supply chain problems require intuition and institutional knowledge AI can't access. **Quality assurance stays human-centered.** AI outputs need human review for accuracy, tone, and alignment with company standards. ## Building a hybrid approach **Audit your delegation patterns.** Categorize tasks into AI-suitable (repeatable work with clear criteria), human-suitable (strategic or relationship-focused), and hybrid (AI generation plus human refinement). Use this simple decision framework to categorize any task: ```mermaid %%{init: {'flowchart': {'curve': 'stepBefore'}}}%% flowchart LR TASK["New Task"] --> QUESTION{"Is it routine
& well-defined?"} QUESTION -->|Yes| AI["🤖 AI Agent
Fast execution"] QUESTION -->|No| QUESTION2{"Requires human
judgment?"} QUESTION2 -->|Yes| HUMAN["👤 Human
Strategic thinking"] QUESTION2 -->|No| HYBRID["🤝 Both
AI draft + Human review"] style AI fill:#ccffcc style HUMAN fill:#ffcccc style HYBRID fill:#ffffcc ``` **Develop prompt engineering skills.** Instead of "analyze competitors," use "compare our pricing, features, and positioning against [specific competitors] for [target market] using [framework]." **Create quality gates.** Use checklists, templates, and automated checks to validate AI work efficiently. **Redefine human roles.** Position team members as AI-augmented experts focused on strategy, relationships, and quality assurance. ## The bottom line **Communication overhead often exceeds the value of human intelligence for routine tasks.** This doesn't mean replacing people, but rather optimizing how you allocate human creativity and AI efficiency. The organizations adapting fastest recognize delegation as a strategic choice. They match tasks to the most efficient executor and build processes that maximize both speed and quality. Master these skills, and communication overhead transforms from a bottleneck into a competitive advantage.

AI agent explained

## The three levels that define modern AI **AI isn't one technology, it's three distinct levels of capability.** Most people lump everything under "AI" without understanding the crucial differences between large language models, AI workflows, and true AI agents. Each level represents a fundamental shift in who controls the decision-making process. Understanding these levels isn't just academic. It determines whether you're using AI as a passive tool, an automated assistant, or an autonomous problem-solver. The distinction shapes what's possible and what you should expect from different AI implementations. ```mermaid %%{init: {'flowchart': {'curve': 'stepBefore'}}}%% graph TD subgraph Level3 ["🤖 Level 3: AI agents"] A3["Autonomous decision making"] B3["Self-judgment & iteration"] C3["Non-deterministic paths"] D3["Goal-oriented behavior"] end subgraph Level2 ["⚙️ Level 2: AI workflows"] A2["Predefined steps"] B2["Human decision making"] C2["Deterministic process"] D2["Multi-step automation"] end subgraph Level1 ["📝 Level 1: Large language models"] A1["Text generation"] B1["Passive response"] C1["Non-deterministic output"] D1["Human controlled"] end Level1 -.-> Level2 Level2 -.-> Level3 classDef level1 fill:#e1f5fe,stroke:#0277bd,stroke-width:2px classDef level2 fill:#f3e5f5,stroke:#7b1fa2,stroke-width:2px classDef level3 fill:#e8f5e8,stroke:#2e7d32,stroke-width:2px class A1,B1,C1,D1 level1 class A2,B2,C2,D2 level2 class A3,B3,C3,D3 level3 ``` ## Level one: large language models LLMs like ChatGPT, Gemini, and Claude represent the foundation layer. They excel at generating and editing text based on your prompts, but they operate within strict boundaries. **LLMs are fundamentally passive.** They respond to what you ask but cannot take independent action. They lack access to your personal data, external systems, or real-time information unless you explicitly provide it. Think of them as highly sophisticated text processors that wait for your instructions. **LLMs are non-deterministic by nature.** Ask the same question twice and you'll likely get different responses due to their probabilistic text generation. This limitation isn't a flaw, it's by design. LLMs provide controlled interactions where you maintain complete oversight of every exchange. ## Level two: AI workflows AI workflows combine LLMs with predefined steps that humans design. These systems can fetch data from calendars, check weather services, or pull information from databases before generating responses. **Workflows automate multi-step processes but follow fixed paths.** They're perfect for predictable, repeatable tasks where you know the sequence of actions needed. Retrieval augmented generation (RAG) is simply a workflow where AI looks up information before answering your question. **Workflows are largely deterministic.** Given the same inputs, they follow the same predefined steps and produce consistent outputs. The human remains the decision maker in workflows. You design the logic, set the parameters, and adjust the process when needed. The AI executes your predetermined steps with impressive efficiency. ## Level three: AI agents [**AI agents are truly autonomous.**](https://memo.d.foundation/arc/on-agent/) The LLM becomes the decision maker, reasoning about the best way to achieve your goal and taking actions using available tools. This represents the fundamental shift from human decision-making to AI decision-making. **Agents can judge their own work and act on that judgment.** They iterate, critique their own outputs, and improve results without constant human intervention. This self-evaluation capability sets them apart from simple automation. They use frameworks like ReAct (reasoning and acting) to plan their approach, execute actions, evaluate results, and adjust their strategy based on what they learn. **Agents are inherently non-deterministic.** Even with the same goal, they might take different paths, make different decisions, and arrive at varied solutions based on their reasoning process. This unpredictability is actually a feature, not a bug, as it enables creative problem-solving and adaptation. Consider this real-world example: an AI vision agent searches video clips for a skier by reasoning what a skier looks like, acting to find relevant footage, and returning results. No human tagged the videos or defined the search criteria. The agent figured it out autonomously, judged the quality of its findings, and refined its approach until it achieved the goal. ## The one massive change that creates agents **Replace the human decision maker in your workflow with an LLM that can reason and act.** This single shift transforms passive automation into adaptive, goal-driven behavior. If you're still making the key decisions about what happens next, you're working with workflows, not agents. True agents take responsibility for determining the best path toward your objective. ## Practical implementation guide **If you want to move from simple automation to true AI agents, focus on shifting decision making from humans to the AI.** This is the fundamental transition that unlocks autonomous behavior. **Start with simple LLMs for text tasks.** Use them for writing, editing, and content generation where you maintain full control over the process. **Add workflows for automation.** When you have predictable, multi-step tasks that benefit from external data integration, workflows provide reliable automation. **Graduate to agents for adaptive solutions.** Deploy agents when you need goal-oriented behavior that can adapt to changing conditions without your constant oversight. The key question for any AI implementation: who is making the decisions? If it's still you, you haven't reached the agent level yet. Let agents handle the trial and error so you can focus on higher-level strategic thinking. **The real value of agents lies in their autonomous ability to adapt, iterate, and improve.** True AI agents don't just automate your existing process. They reason about better ways to achieve your goals, judge the quality of their own work, and adapt their approach based on what they learn without requiring your oversight.

Prompt formula

## The anatomy of prompts that actually work **Most people treat AI prompting like casual conversation, then wonder why the results disappoint.** The difference between mediocre and exceptional AI output isn't the model you're using, it's how precisely you communicate your needs. A structured approach transforms vague requests into clear instructions that consistently deliver useful results. The six-part prompt formula provides a systematic framework for crafting effective prompts: task, context, exemplars, persona, format, and tone. Not every prompt needs all six components, but understanding each one gives you the tools to get exactly what you need from any AI system. ```mermaid %%{init: {'flowchart': {'curve': 'stepBefore'}}}%% graph LR subgraph " " D[Persona

The task component tells the AI exactly what to do, not just what you're thinking about. Instead of "I need help with my resume," use "Review my resume and suggest three specific improvements for a software engineer role." The action verb makes your request unambiguous and actionable. ### Context: provide just enough background **Context shapes the AI's understanding without overwhelming it.** Use three guiding questions to structure your context: - What is the user's background? - What does success look like? - What environment are they in? Too much context creates noise; too little leaves the AI guessing. Focus on details that constrain the possibilities and guide the response toward your specific situation. ### Exemplars: show don't just tell **Examples and frameworks dramatically improve output quality.** Instead of hoping the AI understands your vision, provide concrete examples or reference established frameworks. You can use actual samples ("Write an email similar to this one") or methodological frameworks ("Structure your response using the STAR method"). Both approaches give the AI a clear template to follow. ### Persona: define the voice **Specify who you want the AI to embody.** This could be a professional role ("act as a senior product manager"), a famous person ("respond like Seth Godin"), or even a fictional character for creative tasks. Persona shapes both the expertise level and communication style of the response. A recruiter persona will focus on different aspects than a technical lead persona, even for the same underlying question. ### Format: visualize the output **Close your eyes and picture your ideal response, then describe it.** Do you want bullet points, a table, an email draft, markdown formatting, or something else entirely? Specifying format makes the output immediately usable and saves you formatting time. Instead of receiving a wall of text, you get structured information that fits your workflow. ### Tone: shape the delivery **Tone determines how your message lands.** Friendly, confident, witty, formal, authoritative. Each creates a different impression and serves different contexts. If you're unsure about tone, ask the AI to suggest appropriate tone keywords for your specific situation. This meta-approach often reveals options you hadn't considered. ## Practical implementation strategies **Use the formula as a mental checklist, not a rigid template.** Start with task and context as your foundation, then add other components based on your specific needs. **Prioritize components by impact:** Task is mandatory. Context and exemplars provide the highest value. Persona, format, and tone are valuable additions but not always necessary. **Test the difference:** Compare outputs from a simple prompt versus one using multiple components. The improvement in relevance and usability will convince you to adopt the structured approach. **Build reusable templates:** For recurring tasks, create prompt templates with your preferred persona, format, and tone already specified. This speeds up future requests while maintaining consistency. ## Advanced techniques **Reference existing documents for consistency.** When you need something to match an existing style, tell the AI to "follow the format and tone of this document" rather than trying to describe the style yourself. **Use frameworks as exemplars.** Instead of providing full examples, reference established frameworks like STAR for interview responses, AIDA for marketing copy, or 5W1H for analysis. The AI understands these structures and can apply them effectively. **Make edits visible for review tasks.** When asking for proofreading or editing, request that the AI bold all changes. This lets you quickly scan modifications without reading the entire document. **Combine personas for unique perspectives.** Ask the AI to respond "as a product manager with a background in user research" to get more nuanced expertise than a single role would provide. The six-part formula transforms prompting from guesswork into systematic communication. Master these components, and you'll consistently get AI outputs that are relevant, actionable, and immediately useful for your specific needs.

IC and management

## The career question that changes everything **Before you become a manager, ask yourself: would you want to work for you?** This single question, posed by Philip Su (distinguished engineer at Meta and OpenAI), cuts through career ambitions to reveal a fundamental truth about leadership readiness. Most engineers pursue management for the wrong reasons. Higher pay, more influence, career progression. But management isn't a promotion, it's a career change. The skills that made you successful as an individual contributor (IC) often become irrelevant or even counterproductive as a leader. Su's journey through six switches between IC and management roles at companies like Microsoft, Meta, and OpenAI provides a rare window into what actually drives career success at the highest levels of tech. ## The three drivers that accelerate everything Career growth isn't just about technical skills or putting in hours. Three factors determine how fast you advance: **Luck matters more than people admit.** Being in the right place at the right time creates opportunities that no amount of effort can manufacture. The key is recognizing luck when it appears and being prepared to capitalize on it. **Talent sets the ceiling.** Not everyone can excel at everything. The most successful people identify their natural strengths early and lean into them rather than fighting their limitations. **Hard work amplifies the other two.** When you have similar luck and talent to others, outworking them becomes the differentiator. But this comes with trade-offs in health and relationships. Know the price before you pay it. ## Would you want to work for you? This question deserves deeper exploration because it reveals the gap between management aspiration and management reality. **Most people fail this test initially.** When this question is posed to aspiring managers, the honest answer is usually no. They wouldn't want to work for someone with their current communication style, decision-making process, or emotional regulation. This isn't a character flaw, it's a skill gap. **Self-awareness precedes leadership effectiveness.** Before you can lead others, you need to understand your own patterns. Do you give clear feedback or hint around problems? Do you make decisions based on data or gut feelings? Do you stay calm under pressure or become reactive? Your future reports will experience all of these tendencies amplified. **The assessment goes beyond personality.** Consider your work habits: Do you respond to messages promptly? Do you follow through on commitments? Do you give credit generously and take blame appropriately? These operational behaviors matter more than charisma or vision statements. **Practice leadership before the title.** You can start answering this question positively by leading without authority. Mentor junior colleagues, facilitate team discussions, or coordinate cross-functional projects. These experiences reveal your leadership gaps in low-stakes environments. **Management amplifies everything.** Your quirks become team culture. Your blind spots become organizational weaknesses. Your communication style becomes the template others follow. If you wouldn't want to experience these patterns as an employee, you're not ready to impose them as a manager. ## The IC and management reality **Switching between tracks is possible but costly.** The journey between IC and management often involves taking demotions to return to IC work. The "diamond" model shows transitions are easier early and late in your career, harder in the middle when expectations are highest. **Seniority is about scope, not just skills.** At E7 (senior staff), you drive technical direction for about 50 people. At E8/E9, you multiply impact through qualitative leadership that's hard to define but easy to recognize. The jump isn't just technical, it's about influence and vision. **Ego reset is mandatory.** Returning to IC work might mean reporting to someone who used to be your report. This requires letting go of ego and focusing on where you can contribute best. Your value isn't determined by org chart position. ## Practical implementation guide **Don't specialize too early.** Most people benefit from being generalists in their early careers. Specializing too soon becomes risky if your chosen field becomes obsolete. Try different roles before committing to a specialty. **Value writing as a superpower.** Technical communication multiplies your impact. The best engineers improve their writing by reading great literature and rewriting their work multiple times. Don't dismiss "soft skills" as secondary to technical abilities. **Apply the market leader principle.** Only join the market leader or not at all. Market leaders can afford to experiment and take risks, while followers are forced to play catch-up. This philosophy should guide your high-impact career moves. **Know what you want before chasing it.** Don't be the "dog that caught the car." Many people feel lost after achieving their career goals because they never clarified what they actually wanted. Decisions are easy when your values are clear. Spend time understanding your values to make better choices. The path between IC and management isn't linear, and that's okay. The key is honest self-assessment, especially around that central question. If you wouldn't want to work for yourself today, focus on becoming the leader you'd want to follow. Your future team will thank you. --- *These insights come from Philip Su's detailed discussion about career growth and leadership in this [video conversation](https://www.youtube.com/watch?v=v2JxdjTi_1I) about navigating technical careers.*

You can poke life

"So, the thing I would say is, when you grow up, you tend to get told that the world is the way it is, and your life is just to live your life inside the world, try not to bash into the walls too much, try to have a nice family life, have fun, save a little money. But that's a very limited life. Life can be much broader, once you discover one simple fact, and that is that everything around you that you call life was made up by people that were no smarter than you. And you can change it, you can influence it, you can build your own things that other people can use. The minute that you understand that you can poke life and actually something will, you know, if you push in, something will pop out the other side, that you can change it, you can mold it. That's maybe the most important thing. It's to shake off this erroneous notion that life is there and you're just gonna live in it, versus embrace it, change it, improve it, make your mark upon it. I think that's very important, and however you learn that, once you learn it, you'll want to change life and make it better, 'cause it's kind of messed up in a lot of ways. Once you learn that, you'll never be the same again." *Steve Jobs, 1995 interview* ## Life is simpler than you think **The world's complexity is largely an illusion.** Most people accept a core misconception that shapes their entire approach to life: we believe the structures around us are fixed, unchangeable systems created by superior minds. This belief keeps us passive, accepting limitations that don't actually exist. The reality is startlingly different. Every technology you use, every business model you encounter, every social norm you follow was created by people with the same cognitive abilities you possess. They weren't geniuses with supernatural insight. They were individuals who recognized a simple truth: life responds when you push against it. This insight strips away the mystique we attach to innovation and change. The smartphone didn't emerge from a secret laboratory of superhuman intellects. Apple itself started in a garage with two college dropouts who decided to poke at the computing industry. They discovered what the interview reveals: push in one place, and something pops out elsewhere. ## How to leverage life's malleable nature The practical application of this insight comes down to systematic experimentation. Life's simplicity means you can test, adjust, and iterate your way to meaningful change without requiring permission or perfect preparation. **Start with small experiments.** You don't need a master plan or massive resources. The Apple founders began with a simple circuit board. Today's tools make experimentation even easier. A blog post can test an idea, a basic app can validate a concept, a conversation can open new opportunities. Each small action teaches you how reality responds to pressure. **Question assumed limitations.** Every industry, every social system, every "rule" was established by people. Ask yourself: what assumption am I accepting without testing? Why can't a product be simpler, cheaper, or more accessible? Why can't a process be faster or more efficient? These questions reveal pressure points where life might yield to your push. **Build for real problems.** The most effective approach focuses on creating "things that other people can use." Target genuine frustrations or unmet needs around you. The most successful changes address specific pain points that people actually experience. Start with the user's problem, not your preferred solution. **Persist through resistance.** When you poke life, it pushes back. Funding doesn't materialize, users complain, technology fails. This resistance isn't personal judgment, it's mechanical response. Even Apple faced setbacks with NeXT and early struggles, yet continued pushing. Treat obstacles as data points, not verdicts. ## Why this matters now Today's platforms amplify your ability to poke life. A single post can spark movements, basic prototypes can attract global attention, and open-source tools let you build from anywhere. The barriers that existed in 1995 have largely disappeared. Yet most people still operate under the old assumption: that life is fixed and they must navigate carefully within predetermined boundaries. This creates massive opportunities for those who embrace life's malleable nature. **The problems are waiting.** As the interview points out, life is "messed up in a lot of ways." Climate change, education access, healthcare efficiency, workplace satisfaction - these challenges persist because not enough people believe they can be changed. Each represents a place where focused pressure could yield significant results. The transformation described in that 1995 interview is permanent. Once you truly understand that you can shape reality, you can't return to passive acceptance. The question becomes: what part of life will you poke next?

Ten years strong

> "Not so many tech companies could last this long" - and yet here we are, ten years later, stronger and more innovative than ever. Ten years ago, we started Dwarves Foundation with a simple belief: great software comes from teams who never stop learning. What began as a scrappy tech consultancy has evolved into something we never quite imagined: a strong team spanning multiple time zones, serving clients globally while building one of the most innovative research-first companies in the tech industry. As we mark our tenth anniversary, it's worth reflecting on the lessons learned, the mountains moved, and the path ahead. This isn't just a company milestone; it's a story about adapting, surviving, and ultimately thriving in an industry that never stops changing. ## Five years of transformation The last five years have been transformative, not just for us, but for the entire tech landscape. We've witnessed the rise and evolution of blockchain technology, the mainstream adoption of AI, the shift to remote-first teams, and the emergence of new economic models that blur the lines between traditional employment and community participation. While many companies struggled to adapt to these rapid changes, we found ourselves uniquely positioned. Our commitment to research-first thinking meant we were already exploring these technologies before they became industry trends. This gave us the ability to not just survive the waves of change, but to ride them. ## Six pillars of our last five years ### 1. We learned about money (the hard way) The biggest lesson of the past five years? **Money isn't just about traditional revenue streams anymore.** Through our web3 projects, participating in building blockchain products, and launching our own IDO initiatives, we discovered that value creation in the modern economy is fundamentally different from what it was even a decade ago. We didn't just build blockchain products for clients - we participated in the ecosystem as builders, investors, and innovators. From participating in IDOs to building decentralized applications, from smart contract development to DeFi protocols, we've gained real-world experience with digital assets and tokenomics. **Key achievements:** - Built 20+ blockchain projects across multiple networks ([see our Web3 services](https://memo.d.foundation/services/web3)) - Developed expertise in [DeFi](https://memo.d.foundation/research/topics/defi), [NFTs](https://memo.d.foundation/research/topics/defi/NFT), and smart contract security - Participated in major blockchain ecosystems as both builders and community members ### 2. ICY token builds community through economics In 2020, we introduced ICY, our community token, as an experiment in recognition and reward. What started as a simple tipping system has evolved into a sophisticated economic layer that powers our community engagement. ICY taught us that **community isn't just about culture, it's about economics.** By backing ICY with Bitcoin in our treasury and creating real utility around it, we've built something unprecedented: a borderless software company where contributions are measured, rewarded, and valued in ways that go beyond traditional employment models. Through ICY, we've built up a **treasury backed by Bitcoin**, creating real value for our community members. Our contributors don't just work for traditional compensation - they earn a stake in our collective success. Learn more about [how ICY works](https://memo.d.foundation/handbook/community/icy) and our [tokenomics design](https://memo.d.foundation/misc/tokenomics). **The numbers speak for themselves:** - [335 memo entries](https://memo.d.foundation) published in 2024 alone - Thousands of [ICY tokens](https://memo.d.foundation/handbook/community/icy) distributed to community contributors - A growing [Bitcoin treasury](https://memo.d.foundation/misc/tokenomics/economic-model) that provides real value backing ### 3. Our framework for adapting to new tech waves The past five years brought us face-to-face with massive technological shifts: the blockchain revolution, the AI explosion, the rise of spatial computing, and the emergence of agentic systems. Instead of being overwhelmed by these changes, we developed **a framework for navigating technological evolution with resilience as our priority**. This framework is simple but powerful: - **Research first**: We dive deep into emerging technologies before they become mainstream - **Build quickly**: We create proof-of-concepts and real implementations to understand the potential - **Share openly**: We document our learnings through our [Memo platform](https://memo.d.foundation), building reputation and attracting talent - **Stay flexible**: We adapt our service offerings based on what we learn This approach has kept us ahead of the curve and positioned us as thought leaders in areas like AI engineering, blockchain development, and platform operations. ### 4. EO management framework with leading chairs Traditional hierarchical management doesn't work for a research-first company full of brilliant, curious minds. Over the past few years, we've adopted what we call the **Leading Chairs framework**, a more flexible, autonomous approach to leadership. Think of chairs as department heads with more freedom and responsibility. Each chair owns a specific area of our business: - **[Learning Chair](https://memo.d.foundation/org/2025/learning-chair)**: Labs team that picks up new tech, assesses it, and shares knowledge - **[Delivery Chair](https://memo.d.foundation/org/2025/delivery-chair)**: Client work and project execution - **[Communication Chair](https://memo.d.foundation/org/2025/communication-chair)**: Content creation and brand building - **[Partnership Chair](https://memo.d.foundation/org/2025/partnership-chair)**: Business development and strategic relationships - **[Engagement Chair](https://memo.d.foundation/org/2025/engagement-chair)**: Community building and talent development This model gives us the agility to respond quickly to opportunities while maintaining focus on our core mission of research and innovation. ### 5. Research-first company direction Perhaps our most important evolution has been fully embracing our identity as a **research-first company**. While we still do excellent consulting work, our competitive edge comes from our commitment to pushing the boundaries of what's possible. This research-first approach isn't just philosophical, it's practical. Our research informs our consulting work, our consulting work funds our research, and both contribute to our knowledge base that attracts the best talent and most interesting projects. We've learned that being research-first means: - Saying no to projects that don't teach us anything new - Investing in labs time for every team member - Publishing our insights openly through [Memo](https://memo.d.foundation) - Building internal tools that become products - Attracting talent who want to work on the frontier of technology ### 6. Memo as our knowledge base and legacy [Memo](https://memo.d.foundation) has evolved from a simple blog into a sophisticated knowledge management platform that captures our collective intelligence. It's where we document our research, share our insights, and build our reputation as thought leaders. But Memo is more than just a content platform. It's our **commitment to learning in public**. Every project teaches us something new, and those learnings get captured, refined, and shared with the broader community. This creates a flywheel effect where our knowledge attracts interesting projects, which generate more knowledge, which attracts even better projects. Memo also serves another crucial purpose: it connects generations of Dwarves alumni. Whether someone worked with us ten years ago or joined yesterday, their contributions are captured and preserved in our shared knowledge base. ## What's next in the protocol era As we look ahead, we're not just planning for the next five years. We're architecting the next evolution of what a tech company can be. ### 1. Continue building the research-driven tech company Our core mission remains unchanged: we will continue to be a research-first company that solves interesting problems and pushes the boundaries of technology. But we're scaling this approach through our protocol model, which allows us to work with a broader network of contributors while maintaining our quality and culture. ### 2. Leave more positive footprints Success isn't just about revenue or growth, it's about impact. We want to tackle bigger challenges, work on projects that matter, and help shape the future of technology in ways that benefit everyone. This means being more intentional about the projects we take on and the problems we choose to solve. Our focus areas for 2025 reflect this ambition: - **[AI engineering & agentic systems](https://memo.d.foundation/services/ai)** for automating complex workflows - **[Blockchain development](https://memo.d.foundation/services/web3)** for building decentralized solutions - **[Platform engineering](https://memo.d.foundation/services/platform-ops)** for creating robust, scalable infrastructure - **Spatial computing** for exploring new dimensions of user experience ### 3. Dwarves as a protocol The most ambitious part of our next chapter is transforming from a traditional company into a **decentralized protocol**. Through our [dual-token system](https://memo.d.foundation/misc/tokenomics/tokenomics-design) (ICY for utility, DFG for governance), we're creating a new model for how distributed teams can collaborate, contribute, and benefit from collective success. This isn't just about tokenization for its own sake. It's about creating more sustainable, equitable, and scalable ways to organize talent and resources around research and development. We believe this model will enable us to work with the best people regardless of their location, legal status, or traditional employment preferences. ## Why this matters As we reflect on ten years of building, learning, and adapting, we're struck by how much the definition of a "tech company" has changed. The companies that will thrive in the next decade won't be the ones with the most resources or the biggest teams. They'll be the ones that can learn fastest, adapt most effectively, and create the most value for all their stakeholders. Our journey from a traditional consultancy to a research-first company to a decentralized protocol isn't just about us. It's a glimpse into how all knowledge work might evolve in an age of AI, blockchain, and global connectivity. Not many tech companies last this long, and fewer still manage to continuously reinvent themselves while staying true to their core values. We've survived multiple tech cycles, economic downturns, global pandemics, and fundamental shifts in how software is built and deployed. More importantly, we've created something that attracts brilliant people who want to work on the frontier of technology, solve interesting problems, and be part of something bigger than themselves. ## Lessons learned from the trenches Ten years in the tech industry teaches you a few things: **1. Quality compounds** Every line of code, every design decision, every client interaction builds on the previous one. We've never compromised on quality, and it's paid dividends in client relationships, team satisfaction, and business growth. **2. Community beats competition** The most successful periods in our history have been when we focused on building community rather than just winning clients. Our approach of being both company and community has created more opportunities than any traditional sales strategy. **3. Learning never stops** The technologies we use today didn't exist when we started. The frameworks, tools, and platforms that will define the next decade are probably being invented right now. Staying curious and maintaining a learning mindset is not optional - it's essential for survival. **4. Values are your north star** Market conditions change, technologies evolve, team members come and go - but values remain constant. Our commitment to software craftsmanship, community building, and innovation has guided every major decision we've made. **5. The future is distributed** Remote work, decentralized protocols, global talent pools - the future of work is already here. Companies that embrace distributed models will have access to the best talent and the most innovative ideas. ## A message to our alumni network To every person who has been part of our journey - whether you were with us for a week or several years - your contribution matters. That's why we've created the **contributor profile system** at [memo.d.foundation/contributor](https://memo.d.foundation/contributor). This isn't just nostalgia - it's about building an **onchain record** of your contributions to our collective success. As we evolve into a protocol, these profiles become valuable assets that connect you to a larger network of innovators, regardless of your current relationship with Dwarves. We're keeping that tracked and connecting a larger network of Dwarves, whatever the future holds. This isn't just nostalgia, it's infrastructure for the next phase of our evolution. ## Looking forward Ten years in, we're just getting started. The research-first approach that got us here will carry us forward, but in new forms and with new possibilities. We're excited about the problems we'll solve, the technologies we'll explore, and the impact we'll have. The next ten years will bring challenges we can't yet imagine and opportunities we haven't thought of. But if the past decade has taught us anything, it's that staying curious, staying flexible, and staying committed to learning will see us through whatever comes next. Here's to the next chapter. May it be as surprising, educational, and impactful as the first. --- *Want to be part of our next chapter? We're always looking for brilliant people who love to learn and build.

Speed beats perfectionism in AI adaptation

After studying how developers are navigating the AI transformation, one finding stands out: **developer identity is fundamentally changing, and those who quickly embrace their new role are thriving**. The traditional "developer" identity - focused purely on writing code - is becoming obsolete. This isn't about coding skills anymore. It's about identity transformation speed. ## What the data shows The numbers paint a clear picture: - 50% of developers now report that over half their code is AI-generated - Entry-level hiring dropped 24% in 2024 due to AI adoption - Amazon saved "4,500 developer-years" with AI coding tools But here's the reality check: We're past the "AI assistance" phase. Developers using Claude Code and similar tools report AI is now doing 100% of the coding work - not helping, not assisting, just doing it. The cost barrier has evaporated. What felt expensive at $40/month six months ago now seems trivial. Developers are happily paying $200-500/month for AI tools that deliver what previously took teams months to build. ## The language barrier has collapsed The most immediate impact: language-specific developer roles are becoming obsolete. As one developer put it: "The idea of a 'Python dev' or 'React dev' is outdated. I won't be hiring for languages anymore, I'll hire devs who can solve problems, no matter the stack. The language barrier is completely gone." This shift happened in months, not years. The real skill became system design, architecture, DevOps, cloud - the expertise that separated juniors from seniors. ## The identity transformation pattern Successful developers are shifting their identity across four key dimensions: - **From implementation to intent** - Moving from writing code to defining what should be built - **From delivery to discovery** - Shifting from shipping features to uncovering user needs - **From producer to manager** - Evolving from creating outputs to orchestrating AI systems - **From content to knowledge** - Transitioning from generating code to curating understanding ```mermaid graph TD QA["QA & Architects"] DEV["Development"] PROD["Product"] OPS["Operations"] DATA["Data"] DEV -.->|"From implementation

But only if you have the foundational understanding to guide and review its output. ## Fast vs slow adapters **Fast adapters:** - Experimented with AI tools immediately, pushing them to 100% automation - Focused on system-level thinking rather than competing with AI on implementation - Built capabilities in guiding, reviewing, and correcting AI-generated work - Positioned themselves publicly as AI-augmented problem solvers **Slow adapters:** - Spent months debating whether AI was "real" or temporary - Tried maintaining traditional coding practices alongside AI - Remained attached to language-specific specializations The productivity gap is staggering. Fast adapters report building production-grade applications in weeks that previously took months. One developer shared: "I built a full production-grade desktop app in 1 week. Clean code, better UX than market leaders." ## The technical debt reality Here's what fast adapters learned: AI productivity comes with hidden costs. While AI can rapidly accelerate development, it often produces code that lacks maintainability unless overseen by experienced professionals. The winning approach: Teams that invested in architecture, review automation, and clear specifications consistently outperformed those that didn't. The ability to communicate requirements and maintain architectural vision became a superpower. ## The new developer archetypes Successful transformations cluster around specific new identities: - **AI orchestrators** - Managing complex multi-agent workflows and AI tool chains - **System architects** - Designing frameworks that AI systems can execute reliably - **Quality guardians** - Ensuring AI-generated code meets standards and avoiding technical debt - **Strategic coaches** - Guiding teams through AI adoption and architectural decisions ```mermaid graph TD TRAD["Traditional Developer

Some of the most skilled traditional developers are struggling because they're emotionally attached to manual coding. Meanwhile, developers with moderate technical skills but high adaptability are securing leadership positions. The market rewards speed of adaptation over depth of traditional skills. But there's a caveat: AI tools work best for those who already know what they're doing. The sweet spot is combining domain knowledge with AI-driven productivity. ## The practical takeaway The developers thriving right now: 1. Accepted identity change immediately (weeks, not months) 2. Started pushing AI tools to 100% automation capacity 3. Invested in foundational knowledge to effectively guide AI output 4. Reframed their value around system design and architectural thinking 5. Developed capabilities in reviewing and improving AI-generated work For developers, the window for easy adaptation is closing. The ones who moved fast have captured the premium positions and are seeing massive productivity gains. Those still debating language specializations will find themselves playing catch-up. **The bottom line: The developer identity is fundamentally shifting from language-specific coding to system-level problem solving. Speed of embracing this new identity beats technical perfectionism every time**. Don't just learn to use AI tools - learn to become indispensable at guiding and reviewing their output. Own the architecture, own the process, and own the transformation. *Sources: Insights from [Dev jobs are about to get a hard reset](https://www.reddit.com/r/ClaudeAI/comments/1lhgdbd/dev_jobs_are_about_to_get_a_hard_reset_and/).*

How to choose the best AI visibility tool

AI visibility tracking is no longer optional if you want your content to stay seen. But with new tools popping up every month, picking the right one can feel like a maze. Here’s how to navigate the options, what to look for, and how to avoid getting stuck with a tool that doesn’t fit your workflow. ## Start with your real use case Before you look at dashboards or pricing, get clear on what you need. Are you tracking brand mentions, content citations, or competitor visibility? Do you want daily alerts or monthly reports? The right tool will match your actual workflow, not just look good in a demo. ## Vet the data: Where does it come from? Not all AI visibility tools pull data the same way. Some use direct API access, others scrape model outputs, and a few rely on third-party panels. Ask these questions: - Which AI platforms are tracked (ChatGPT, Gemini, Perplexity, Google AI Overviews, etc.)? - How fresh is the data? Is it real-time, daily, or weekly? - Can you see the raw outputs or just summaries? If the tool can’t answer these, keep looking. ## Popular AI visibility tools - Profound: Strong for enterprise teams, detailed tracking, and competitor analysis. - AthenaHQ: GEO-focused, with daily tracking and actionable insights. - Semrush: Expanding into AI tracking with its established SEO toolkit. - AI Visibility, Peec AI, Rankscale, Otterly.AI: Each offers a slightly different spin—compare features, pricing, and ease of use. ![](assets/profound-answer-engine-insights.webp) ## Test with your own content Most tools look slick in a sales pitch. The real test is running your own prompts and checking if the results match what you see in live AI answers. Try a trial or demo with your actual memos or brand terms. If the tool’s numbers don’t line up with reality, that’s a red flag. ## How to test before you commit - Always ask for a demo or trial. Don’t sign a long contract without hands-on testing. - Run your own prompts and check if the tool’s results match what you see in live AI answers. - Get feedback from both writers and engineers. Everyone needs to be able to use the tool, not just the analytics team. ## Don’t ignore the basics - Is the pricing clear, or are there hidden fees? - Does it fit your budget and scale as your needs grow? - Can your whole team use it, or is it locked down to a few seats? ## Consider support and adaptability AI search moves fast. You want a tool that updates quickly and has support you can reach when things break or change. Ask about update cycles, new feature rollouts, and how fast they adapt to new AI platforms. ## What if you’re a solo writer or small team? You don’t need the biggest tool on the market. Look for platforms with clear dashboards and no-code setup. Even basic tracking is better than flying blind **FAQ** **Do I need to track every platform?** Start with the ones your audience uses most. Expand as you grow. **What if my tool’s data doesn’t match what I see in ChatGPT?** No tool is perfect. Use tracking as a guide, but always double-check with manual prompts now and then. ## Bottom line Choosing the right AI visibility tool is like picking a compass for the new search landscape. Take your time, test with your real content, and pick the one that helps your team move fast and stay seen.

Seeding your content for AI: a writer’s guide

*Leverage the platforms LLMs love so your memos get quoted and drive AI-first discovery.* ![](assets/seeding-content-for-ai.png) ## Why "seeding" matters in GEO Seeding means placing your memo’s key ideas or summaries on platforms like Reddit, YouTube, and Quora, places that large language models crawl for fresh, trustworthy content. If you want your work to show up in AI-generated answers, you can’t just publish on your own site and hope for the best. You need to meet the models where they are. You don’t have to do everything at once. Even posting a strong summary on one platform can boost your memo’s chances of being cited. ## Reddit tactics Reddit is a goldmine for LLMs. Perplexity, ChatGPT, and others reference Reddit threads heavily—often more than standalone blogs. **Where to Post** - r/Programming, r/Golang, r/AI, r/LearnProgramming - Pick subreddits with 50K+ members and active daily threads **Thread format** - Title (max 60 characters): `Memo Highlights: Building a Deep-Search Pipeline in 3 Steps` - Body (100–150 words): - Opening hook: State the problem in one sentence - Three key points: Bullet out your memo’s takeaways - Link: Full memo URL at the end - Call to action: “Questions? Share your challenges below!” **Engagement tips** - Reply within 1 hour to every comment to keep your thread visible. - Upvote insightful replies to encourage quality discussion. - Use flair if the subreddit allows (like “Article” or “Discussion”). ## YouTube clip playbook Google AI Overviews often parse and quote video transcripts. A short, direct video can get your message into the AI ecosystem. **Script template (30–60 seconds)** - 0–5s: Hook “Struggling to track AI citations? Here’s how in three steps.” - 5–20s: Bullet 1 “Define representative prompts questions that mirror real reader queries.” - 20–35s: Bullet 2 “Automate nightly API calls to record citations.” - 35–50s: Bullet 3 “Chart weekly reference rates in Grafana and set alerts.” - 50–60s: Outro CTA “Full guide at memo.d.foundation/deep-search-pipeline. Link below!” **Production tips** - On-screen text: Display each bullet as it appears in the memo. This helps with transcript parsing. - Description & pinned comment: Include the full memo URL and a one-sentence summary. - Tags & title: Use “Deep-search pipeline” and “GEO” in your video title and tags. ## Quora answer format Quora’s Q&A structure maps directly to how LLMs organize knowledge. **Identify questions** - Search for topics like “How to track AI citations” or “What is reference rate?”. - Pick questions with 1K+ followers or recent activity. **Answer template (75–100 words)** 1. Direct answer (2–3 sentences): “Reference rate is the percentage of questions in which an LLM cites your page.” 2. Brief rationale (1–2 sentences): “High reference rates signal to AI that your content is authoritative and structured.” 3. Read more link: “Learn more in our memo: memo.d.foundation/guides/reference-rate”. **Best practices** - Use a neutral tone, focus on insight, not marketing. - Paste the full URL, not a link shortener. - Engage commenters and answer follow-up questions to boost visibility. ## Measuring seeding success | **Platform** | **What to watch** | **Tools to use** | | --- | --- | --- | | Reddit | Upvotes, comments, new AI citations for that memo | Profound, manual prompts | | YouTube | Views, watch-through rate, transcript hits | YouTube Analytics, Profound | | Quora | Views, upvotes, “linked source” clicks | Quora stats, Profound | - Record metrics before posting. - Re-run your 20-prompt batch 24–48 hours later to gauge citation change. - Share a before/after snapshot in your team chat. **Pre-posting checklist** - Title matches memo heading for semantic alignment. - Body uses “In summary” hooks and clear bullets. - Full memo URL is correct and visible. - Three discussion prompts ready for replies. *Seeding is how you get your memo in front of both people and AI. Start small, use the templates, and watch your reference rates climb.*

Talks and takeaways from the scene part 3: Three Crypto Events, One Reality Check

Just wrapped up three crypto events that painted a pretty clear picture of where we're at right now. Here's what I saw on the ground. ## **Web3 Builders' Summit: Speed is Everything** The pace is absolutely wild. Teams are going from idea to beta in two weeks flat. Not two months, not six weeks – *two weeks*. This isn't just startup hustle anymore; it's survival mode in the most competitive product landscape crypto has ever seen. Key observations: - Everyone's racing to ship, but also racing to find actual product-market fit - Funding pressure is real – next wave could dry up fast - The days of raising on whitepapers are long gone - Now it's all about traction, users, and real metrics ## **SuperVietnam in Danang: The Quiet Revolution** Danang caught me off guard. While everyone's been watching Thailand and Singapore, Vietnam has been quietly building serious blockchain infrastructure. The numbers don't lie: - Da Nang jumped 130 places in the 2025 Global Start-up Ecosystem Index - That's not gradual progress – that's rocket ship trajectory - Tran Huyen Dinh (Chairman, Fintech Application Committee, Vietnam Blockchain Association) highlighted this as proof of strong digital economy strategies The infrastructure play is smart: - Da Nang Hi-Tech Park offers extended tax breaks - Equipment import exemptions for high-tech investment - Nguyen Thi Anh Thi (Vice Chairwoman, Da Nang People's Committee) outlined their strategy: tax exemptions, infrastructure support, controlled trials for new technologies - They're basically building regulatory sandboxes before calling them that What struck me most was the pragmatic approach. Vietnamese institutions aren't trying to reinvent the wheel; they're looking at what worked in other markets and adapting it locally. The conversations I overheard between government officials and builders felt refreshingly productive, not adversarial. This feels like the early Singapore playbook all over again. ## **Solana Summit APAC: Pivots and Realizations** The Solana event revealed something interesting about market maturity. Teams that started building DeFi protocols are quietly pivoting to enterprise solutions. The numbers back this up: Coinbase reports that 60% of Fortune 500 companies are working on blockchain projects. That's not crypto Twitter hype – that's boardroom reality. ![](assets/event3-1.webp) Major shifts I noticed: - Uniswap's move into custom enterprise tools isn't an outlier – it's a trend - VCs are burnt out on usual narratives: RWA, DePIN, AI crypto, gaming, memes - Everyone's heard these pitches a thousand times - But the enterprise pivot makes sense when you see the Fortune 500 adoption numbers But here's the thing: the actual projects in these spaces are still getting built and funded. Teams still pushing forward despite narrative fatigue: - Inferix GPU - Botanika - Datagram Network The consumer app experiments on new chains like Berachain and Sonic are where the real energy is. These aren't trying to be the next billion-dollar protocol; they're just trying to be useful. ## **The OG Comeback Tour** The OG projects are raising again: - Rise Chain - Orochi Network - Names that felt dormant are suddenly back in fundraising mode This isn't coincidence. There's institutional memory and battle-tested teams behind these projects that new VCs are starting to appreciate again. Experience matters more than it has in years. ## **Key Takeaways** - **Execution over everything**: The idea phase is dead. Ship fast, iterate faster, or get left behind. Two-week cycles from concept to beta aren't ambitious anymore – they're table stakes - **Geography matters again**: Vietnam is positioning itself as the next major crypto hub while everyone's distracted elsewhere. The regulatory sandbox approach in Da Nang could become the blueprint everyone copies - **Narrative fatigue is real but selective**: VCs may be tired of hearing about DePIN and RWA, but they're still funding the best teams in these spaces. Finding the right story at the right moment matters as much as the product itself - **Enterprise is the new DeFi**: B2B solutions are quietly becoming the most sustainable business models in crypto. Fortune 500 adoption numbers don't lie – this is where the real money is moving - **OG teams are back**: Experience and proven execution are premium assets in this market. Battle-tested founders who survived previous cycles are getting premium valuations again - **Connections beat content**: The main stage talks are impressive, but the real deals happen in hallway conversations. Everyone's hunting for that next connection or partnership that keeps their project alive - **Speed isn't just about building**: It's about reading market signals, pivoting when narratives shift, and staying ahead of trend cycles. The teams that survive are the ones that can adapt faster than the market moves ## **What's Next** **Globally:** - More enterprise pivots across the board - Geographical diversification of crypto hubs - Continued focus on real utility over token mechanics - Markets with practical crypto regulation will capture next wave of institutional adoption **In Vietnam:** - Watch for major exchange launches - More government partnerships incoming - Vietnam potentially becoming the Southeast Asian crypto gateway that everyone expected Thailand to be - Da Nang's regulatory sandbox approach could become the regional model The hype cycle is dead. The build cycle is just getting started.

The grind behind GEO: what it really takes to stay seen

It’s easy to talk about GEO like it’s a checklist: optimize your memo, track your reference rate, celebrate when an AI finally quotes you. But the reality is messier. Staying visible in the age of generative engines is a grind. It’s not a one-time win, it’s a cycle of writing, tracking, editing, and adapting. Here’s what the work really looks like behind the scenes. ## The never-ending update loop You publish a guide. Maybe it gets picked up by AI models for a few days. Feels good. But then a model update rolls out, or a competitor rewrites their page, and suddenly your memo drops off the citation radar. What do you do? You go back in. You tweak the summary. You sharpen the bullets. You check if your FAQ still matches the questions people actually ask. GEO is not set-and-forget. It’s a constant race against entropy. The web shifts, the models shift, and you have to shift with them. ## Tracking takes grit Manual tracking is tedious. Automated dashboards break. Reference rates dip for no clear reason. You find yourself running batch prompts at midnight or scanning Discord alerts before your morning coffee. Sometimes you spend hours chasing a 2 percent lift that nobody outside your team will ever notice. But the grind is the point. Anyone can optimize once. The teams that win are the ones who keep watching, keep iterating, and never let their memos slip into obscurity. ## Editing without ego In the GEO world, your favorite turn of phrase might never get quoted. That clever intro? Cut if it doesn’t help your reference rate. The best GEO writers learn to kill their darlings, rewrite for clarity, and structure for the machine as much as for the human. It’s not about showing off. It’s about being useful, being clear, and being the answer the AI needs. ## The invisible work Most of what makes GEO work is invisible. Readers see the polished memo, not the ten drafts that came before. They don’t see the Discord threads, the “why did our FAQ drop to 5 percent?” debates, or the late-night fixes after a model update. But this is where the real craft lives. It’s in the details, the persistence, and the willingness to keep pushing even when the numbers don’t move. ## Why it’s worth it GEO is not glamorous. It’s not always fun. But when your memo gets cited by an AI, when your niche topic finally shows up in a generative answer, you know you’ve earned it. You didn’t just chase the algorithm. You put in the work to make sure your knowledge survives. That’s the grind behind GEO. It’s not for everyone. But if you want your work to matter in the age of AI, it’s the only way to stay seen.

Stand up GEO tracking tools: a simple guide

*Measure what matters, iterate with confidence.* ![](assets/geo-tracking-tools.png) ## Why we must track GEO GEO tracking is about knowing if your content is showing up in AI-generated answers. If you can’t see which memos are being cited, you’re guessing about what works. - It tells you which articles get picked by AI and which don’t. - You can see if your updates make a difference. - You get proof that your work matters when the numbers go up. ## What we need to watch You don’t need to build dashboards or write code. Focus on these three things: | **Metric** | **Plain-english meaning** | **Why writers care** | | --- | --- | --- | | **Reference rate** | How often does an AI mention your memo when asked relevant questions? | This tells you if your content is visible. | | **Paragraph winner** | Which part of your memo does the AI quote? | This helps you see what structure or section works best. | | **Clicks on surfaced link** | Do people actually click through when your memo is cited? | This shows if AI citations bring real readers. | ## How to track without coding You don’t have to build a DIY stack. Here’s what you can do: - Use a commercial tool like Profound or Semrush AI Toolkit. These are built for non-technical folks. You just sign up, add your main prompts (the questions you want your memo to answer), and run a batch test. The tool shows which memos get cited. - If you don’t want to use a tool, you can search for your memo’s title or main points in ChatGPT or Gemini and see if it appears in the answer. Keep a simple checklist in Notion or Google Sheets to track which ones show up. ## Tooling paths at a glance | **Path** | **Set-up time** | **Cost** | **Pros** | **Cons** | | --- | --- | --- | --- | --- | | **Commercial pilot**(Profound, Semrush AI Toolkit) | 1–2 h | \$ -- \$\$ | No code, dashboards out of the box | Ongoing fees, fewer custom prompts | | **DIY stack**(LangChain + Google Sheet + Grafana) | 4–8 h | \$ (API only) | Full control, free to run | Needs a few engineering hours | | **Hybrid** | 1 h + 4 h | \$\$ | Start fast with SaaS, fall back on DIY | Two systems to watch | *If you’re not technical, use the commercial pilot path. You can get started in about an hour. ## Example: How to track and improve a Memo Memo: “How to build a deep-search pipeline” URL slug: /guides/deep-search-pipeline **Baseline test (Writer, about one hour):** 1. Sign up for a Profound trial. 2. Paste your 20 GEO test prompts, for example, “According to memo.d.foundation, how do I set up a deep-search pipeline?” 3. Click Run. 4. Export the CSV. 5. See that /guides/deep-search-pipeline is cited in only 4 of 20 prompts (20 percent), below the 10 percent threshold. **Retrofit the memo (Writer, about two hours):** - Add a “What you’ll learn” summary at the top. - Insert “Key takeaways” bullets. - Wrap steps in a HowTo block and add a short FAQ at the bottom. **Verification (Writer, about five minutes):** - Wait 24 hours, then check results. - Today’s citation count: 12 of 20 prompts (60 percent). - Celebrate: “Our retrofit raised reference rate from 20 percent to 60 percent in one day”. - Share screenshot in your team chat as proof. **Continuous improvement:** - Repeat for the next low-performing memo. - Keep an eye on your checklist or dashboard and tweak content if citations dip again. ## The bottom line You don’t have to be an engineer to track GEO success. Focus on what you can see: is your memo being cited, which part is quoted, and do people click through? Use simple tools or manual checks. The goal is to write content that AI engines want to cite and to know when your work is paying off.

Economic model

A sustainable protocol needs predictable revenue, manageable costs, and aligned incentives. The dual-token system with Bitcoin backing creates multiple value capture mechanisms while maintaining operational flexibility. ## Executive summary The Dwarves+ Protocol economic model is designed to create a self-sustaining ecosystem where value flows align with protocol growth, contributor rewards, and long-term sustainability. The dual-token system with Bitcoin-backed value layer balances short-term utility (ICY) with long-term governance and value accrual (DFG), while providing tangible asset backing through Bitcoin treasury reserves. ## Economic foundation ### Value creation sources 1. **Technical consulting services**: Core revenue from client projects 2. **Research publication**: Intellectual property monetization 3. **Open source contributions**: Reputation and partnership value 4. **Community network effects**: Increased platform value with user growth 5. **DeFi protocol services**: Yield generation and financial services 6. **Bitcoin treasury appreciation**: Long-term value accrual from BTC reserves ### Value capture mechanisms - **Service commissions**: 15-30% commission on consulting projects - **Partnership revenue**: Revenue sharing from strategic alliances - **Premium features**: Advanced protocol tools and analytics - **Staking yields**: Interest on staked tokens and liquidity provision - **Transaction fees**: Nominal fees on protocol interactions - **Treasury management**: Bitcoin appreciation and DeFi yield strategies ## Token economic flows ### ICY token (utility) economics #### Supply side - **Initial supply**: 100M ICY tokens - **Inflation rate**: 2-5% annually (dynamic based on growth) - **Maximum supply**: 1B ICY tokens (hard cap) - **Bitcoin backing**: Dynamic value floor based on BTC treasury holdings -

Governance framework

Moving from team control to community governance requires careful design. The transition must maintain protocol direction while gradually distributing decision-making power to stakeholders. ## Overview The Dwarves+ Protocol governance framework is designed to transition from centralized team control to community-driven decision-making while maintaining operational efficiency and strategic direction. This document outlines the governance structure, voting systems, and implementation roadmap for progressive decentralization. ## Governance philosophy ### Core principles 1. **Progressive decentralization**: Gradual transition from team control to community governance 2. **Stakeholder alignment**: Decision-making power proportional to long-term commitment 3. **Expertise recognition**: Mechanisms to leverage domain knowledge and experience 4. **Transparency**: All governance processes publicly auditable and documented 5. **Adaptability**: Governance systems that evolve with protocol maturity ### Governance objectives - **Protocol direction**: Strategic decisions on research focus and partnerships - **Resource allocation**: Treasury management and funding distribution - **Parameter optimization**: Token economics and reward mechanism adjustments - **Community standards**: Quality assurance and contributor guidelines - **Risk management**: Security measures and emergency response protocols ## Comprehensive governance voting systems The Dwarves+ Protocol implements a sophisticated voting system that evolves through three distinct phases, each designed to address different stages of protocol maturity and community development. ### Voting system overview #### Purpose and scope - **Primary function**: Facilitate decisions on research funding, partnerships, profit allocation, and protocol upgrades - **Governance token**: DFG with staked tokens receiving enhanced voting weight (2x multiplier) - **Transition goal**: Move from 100% team control to 50% community governance by Q2 2026 - **Long-term vision**: Achieve 75%+ decentralized governance while maintaining strategic coherence #### Governance token (DFG) mechanics - **Total supply**: 1,000,000 DFG (fixed supply) - **Voting power**: Base 1 DFG = 1 vote, with staking multipliers - **Minimum proposal**: 1,000 DFG required to submit proposals - **Eligibility**: All DFG holders can participate in governance ### Phase 1: Initial governance (Q3-Q4 2025) #### One token, one vote (1T1V) system **Core mechanics**: - **Voting weight**: 1 DFG = 1 vote (no staking multipliers) - **Council oversight**: 5-member team-appointed council with veto power - **Veto threshold**: Council can block proposals that drain >20% of treasury - **Quorum requirement**: 10% of total DFG supply (100,000 DFG) - **Approval threshold**: Simple majority (51%) **Implementation details**: ```solidity // Simplified voting calculation for Phase 1 function calculateVotingPower(address voter) public view returns (uint256) { return dfgToken.balanceOf(voter); } function isProposalApproved(uint256 proposalId) public view returns (bool) { Proposal memory proposal = proposals[proposalId]; uint256 totalVotes = proposal.forVotes + proposal.againstVotes; // Check quorum (10% of total supply) if (totalVotes < (dfgToken.totalSupply() * 10) / 100) { return false; } // Check majority approval return proposal.forVotes > proposal.againstVotes; } ``` **Proposal categories**: 1. **Research funding**: Up to $50,000 per proposal 2. **Partnership approvals**: Strategic alliances and collaborations 3. **Parameter adjustments**: Minor tokenomics modifications 4. **Community initiatives**: Events, bounties, and engagement programs **Council veto powers**: - **Treasury protection**: Prevent proposals that risk protocol solvency - **Security measures**: Block potentially harmful technical changes - **Quality control**: Ensure proposals meet minimum standards - **Strategic alignment**: Maintain focus on core mission ### Phase 2: Transition governance (Q1-Q2 2026) #### Staked-weighted voting with quadratic adjustment (SWV-QA) **Enhanced mechanics**: - **Base voting**: Unstaked DFG = 1 vote - **Staking bonus**: Staked DFG = 2 votes - **Whale mitigation**: Quadratic adjustment for large holders - **Council evolution**: Elected by DFG holders, reduced veto power (25% override) - **Quorum increase**: 15% of total DFG supply (150,000 DFG) - **Threshold variation**: 51% for standard, 66% for profit reallocation **Mathematical model**: $$Vote_{weight} = \begin{cases} DFG_{unstaked} & \text{for unstaked tokens} \\ DFG_{staked} \times 2 \times \sqrt{\frac{1000}{DFG_{staked}}} & \text{for large staked holders} \\ DFG_{staked} \times 2 & \text{for unstaked tokens < 1000} \end{cases}$$ **Example calculations**: | DFG Holdings | Staking Status | Raw Votes | Adjusted Votes | Effective Power | |--------------|----------------|-----------|----------------|-----------------| | 100 | Unstaked | 100 | 100 | 0.1% | | 100 | Staked | 200 | 200 | 0.2% | | 1,000 | Staked | 2,000 | 2,000 | 1.8% | | 10,000 | Staked | 20,000 | 6,325 | 5.7% | | 50,000 | Staked | 100,000 | 14,142 | 12.8% | **Implementation code**: ```solidity function calculateVotingPower(address voter) public view returns (uint256) { uint256 unstakedDFG = dfgToken.balanceOf(voter) - stakedDFG[voter]; uint256 stakedTokens = stakedDFG[voter]; uint256 baseVotes = unstakedDFG; uint256 stakedVotes; if (stakedTokens > 0) { if (stakedTokens >= 1000) { // Apply quadratic adjustment for large holders stakedVotes = stakedTokens * 2 * sqrt(1000) / sqrt(stakedTokens); } else { // Full 2x multiplier for smaller holders stakedVotes = stakedTokens * 2; } } return baseVotes + stakedVotes; } ``` **Governance split mechanism**: - **Team allocation**: 400,000 DFG (40% of supply) - **Community earned**: 400,000 DFG via ICY staking - **Reserved pool**: 200,000 DFG for future distribution - **Effective control**: ~50% community, 50% team by Q2 2026 ### Phase 3: Decentralized governance (Post-2026) #### Delegated quadratic voting (DQV) **Advanced mechanics**: - **Vote weight**: $\sqrt{DFG_{held} + DFG_{delegated}}$ - **Delegation system**: Token holders can delegate to expert representatives - **Automated execution**: Smart contract-based proposal implementation - **No council**: Fully decentralized decision-making - **Higher quorum**: 20% of total DFG supply (200,000 DFG) - **Threshold maintained**: 51% standard, 66% for critical changes **Delegation framework**: $$Delegate_{power} = \sqrt{\sum_{i=1}^{n} DFG_{delegated,i}} + \sqrt{DFG_{owned}}$$ Where: - $n$ = number of delegators - $DFG_{delegated,i}$ = tokens delegated by user $i$ - $DFG_{owned}$ = delegate's own tokens **Representative categories**: 1. **Research leads**: Domain experts in specific technical areas 2. **Community managers**: Focus on contributor experience and engagement 3. **Economic advisors**: Specialists in tokenomics and treasury management 4. **Security experts**: Focused on protocol safety and risk management ### Implementation architecture #### Smart contract system **Core contracts**: 1. **GovernanceToken.sol**: DFG token with delegation functionality 2. **Governor.sol**: Main governance logic and proposal management 3. **Timelock.sol**: Execution delay for approved proposals 4. **VotingPowerCalculator.sol**: Phase-specific voting weight calculations **Proposal lifecycle**: ```mermaid flowchart TD A[Proposal Submission] --> B{Minimum DFG Check} B -->|< 1,000 DFG| C[Rejection] B -->|≥ 1,000 DFG| D[7-Day Review Period] D --> E[Council/Community Feedback] E --> F[14-Day Voting Period] F --> G{Quorum & Threshold Met?} G -->|No| H[Proposal Fails] G -->|Yes| I{Council Veto?} I -->|Yes| J[Proposal Blocked] I -->|No| K[48-Hour Timelock] K --> L[Execution] %% Styling classDef success fill:#d4edda,stroke:#155724 classDef failure fill:#f8d7da,stroke:#721c24 classDef process fill:#e2e3e5,stroke:#383d41 class L success class C,H,J failure class A,D,E,F,K process ``` #### Proposal types and requirements | Proposal Type | DFG Required | Threshold | Timelock | Council Veto | |---------------|--------------|-----------|----------|--------------| | Research Funding (<$10K) | 1,000 | 51% | 24 hours | No | | Major Funding ($10K-$50K) | 2,500 | 51% | 48 hours | Phase 1-2 | | Treasury Allocation (>$50K) | 5,000 | 66% | 72 hours | Phase 1-2 | | Parameter Changes | 1,000 | 51% | 48 hours | Phase 1-2 | | Emergency Actions | 10,000 | 75% | 12 hours | No | | Constitutional Changes | 25,000 | 75% | 7 days | Phase 1-2 | #### Voting process implementation **Step 1: Proposal submission** ```solidity function propose( address[] memory targets, uint256[] memory values, bytes[] memory calldatas, string memory description ) public returns (uint256) { // Implementation details } ``` **Step 2: Voting** ```solidity function castVote(uint256 proposalId, uint8 support) public { // Implementation details } function castVoteWithReason(uint256 proposalId, uint8 support, string memory reason) public { // Implementation details } ``` **Step 3: Proposal execution** ```solidity function execute(uint256 proposalId) public payable { // Implementation details } ``` #### Governance dashboard and analytics **Key metrics**: -

**Sybil attacks**: KYC for DFG holders (Phase 2), reputation scores #### Emergency procedures - **Protocol pause**: 75% DFG vote to temporarily halt operations (30 days) - **Treasury freeze**: Council (Phase 1-2) or 75% DFG vote to freeze treasury - **Bug bounties**: Continuous programs for smart contract security #### Formal verification and audits - **Smart contract audits**: Regular third-party audits of governance contracts - **Formal verification**: Mathematical proof of protocol correctness - **Bug bounty programs**: Ongoing incentives for security researchers ### Governance roadmap and milestones #### Phase 1 (Q3-Q4 2025): Initial setup - **Launch 1T1V**: One token, one vote system activated - **Council establishment**: 5-member initial council nominated - **Basic proposal flow**: Research funding, minor parameter changes - **DFG distribution**: Initial allocation to team and early contributors #### Phase 2 (Q1-Q2 2026): Transition and growth - **SWV-QA implementation**: Staked-weighted quadratic voting online - **Council elections**: First community elections for council members - **Expanded proposal types**: Partnerships, major treasury allocations - **50% community control**: Governance power shifts gradually #### Phase 3 (Post-2026): Full decentralization - **DQV activation**: Delegated quadratic voting fully implemented - **Council dissolution**: Automated execution via smart contracts - **Self-sustaining governance**: Community-driven evolution - **Cross-chain governance**: Integration with other blockchain networks ### Legal and compliance considerations #### Regulatory environment - **Jurisdiction**: US/Singapore compliance framework - **Security vs. utility**: Legal opinion on DFG (security) and ICY (utility) classification - **AML/KYC**: Compliance for DFG holders (Phase 2) #### Legal structure - **Decentralized autonomous organization (DAO)**: Formal legal wrapper (if applicable) - **Foundation model**: Non-profit entity supporting protocol development - **Legal counsel**: Ongoing consultation for regulatory changes ## Conclusion The Dwarves+ Protocol governance framework is a dynamic system designed for progressive decentralization, balancing initial team guidance with long-term community control. By empowering DFG holders through fair voting mechanisms, robust incentives, and transparent processes, we aim to build a resilient, innovative, and truly decentralized research and development ecosystem.

Tokenomics design

Two tokens solve different problems. ICY handles daily rewards and transactions. DFG enables governance and long-term value capture. Bitcoin backing provides stability and growth potential that pure utility tokens can't match. ## Token architecture ### ICY token (utility token) #### Core properties - **Symbol**: ICY - **Type**: ERC-20 Utility Token - **Total supply**: Dynamic (starts at 100M, adjusts based on protocol activity) - **Decimals**: 18 - **Value backing**: Bitcoin-backed through treasury reserves #### Supply mechanics - **Inflation rate**: 2-5% annually based on protocol growth - **Burn mechanisms**: - 1% of transaction fees - Governance-voted burn events - Unused treasury allocations (quarterly burn) - Bitcoin-triggered buyback and burn (automatic) - **Maximum supply**: 1B ICY tokens (hard cap) #### Value backing system ICY tokens are backed by Bitcoin held in the protocol treasury, creating a dynamic value floor: - **Backing ratio**: Variable based on BTC treasury size and ICY circulation - **Initial conversion**: Approximately 0.00003 BTC per ICY (adjusts with market) - **Value calculation**: ICY Value = (BTC Treasury Size / ICY Circulation) × BTC Price - **Liquidity pools**: Separate BTC and ICY pools maintain market pricing #### Utility functions 1. **Contribution rewards**: Primary reward mechanism for all protocol activities 2. **Staking**: Stake ICY to earn protocol yield and voting power multipliers 3. **Transaction fees**: Pay for premium protocol services 4. **Liquidity provision**: Provide liquidity for protocol DEX pairs 5. **Reputation boost**: Burn ICY to increase contributor reputation scores #### Earning mechanisms Contributors earn ICY through verified activities: | Activity | ICY Reward Range | Verification Method | |----------|------------------|-------------------| | Research Publication | 100-1,000 ICY | Peer review + citation metrics | | Code Contribution | 50-500 ICY | Pull request review + impact assessment | | Community Engagement | 10-100 ICY | Engagement metrics + quality scores | | Mentoring | 25-250 ICY | Mentee progress + feedback ratings | | Partnership Development | 200-2,000 ICY | Deal value + success metrics | | Bug Bounty | 100-5,000 ICY | Severity level + fix verification | ### DFG token (governance token) #### Core properties -

By incentivizing productive contributions, fostering long-term holding through staking, and integrating Bitcoin backing for stability, ICY aims to be a robust and valuable utility asset that scales with the protocol's success.

Whitepaper

## Abstract Dwarves+ Protocol represents the evolution of Dwarves Foundation from a traditional tech research firm into a decentralized protocol that incentivizes collaborative research, development, and knowledge sharing. Through a dual-token system comprising ICY (utility) and DFG (governance) tokens, the protocol creates sustainable economic incentives for developers, researchers, and partners while maintaining community governance. ## Vision To build the world's premier decentralized research and development protocol, where expertise flows freely, collaboration is rewarded, and innovation is governed by the community. ## Problem Statement Traditional tech consulting and research firms face several challenges: - Limited scalability due to centralized structures - Difficulty in fairly compensating distributed talent - Lack of transparency in research funding and allocation - Barriers to entry for independent researchers and developers - Misaligned incentives between company growth and contributor value ## Solution: Dwarves+ Protocol ### Core Principles 1. **Research-First**: Prioritizing deep technical research and innovation 2. **Community-Governed**: Democratic decision-making through token holders 3. **Merit-Based Rewards**: Contributors earn based on value delivered 4. **Open Collaboration**: Welcoming diverse teams and individuals 5. **Sustainable Economics**: Self-reinforcing token economics ### Protocol Components #### Dual Token System -

On agentic AI

## The wave we're riding We're witnessing something different this time. **Agentic AI** isn't just another LLM wrapper or chatbot upgrade. These are AI systems that actually make decisions and execute complex tasks without constantly asking for permission. What makes this interesting? **Autonomous reasoning**. These systems can plan, adapt, and coordinate with other agents to solve problems we'd normally need humans for. **What it's good at:** - Automating multi-step workflows that require actual thinking - Making real-time decisions in dynamic environments - Coordinating between different systems and data sources - Scaling operations without scaling headcount **What it's not good at:** - Tasks requiring deep emotional intelligence - Creative work that goes beyond pattern recognition - Situations where ethical judgment is paramount - Environments with poor data quality or unclear objectives **Our goal is simple:** to do more with less. And agentic AI might finally make that possible at scale. ## How we're upgrading ### Skills we're unlocking We're not just building chatbots anymore. We're developing **AI workflows** and **agent orchestration systems** that act as copilots in our daily work. Key focus areas: - **Reducing production costs** across code, design, documentation, and communication - **Knowledge discovery** from our growing internal database - **Shared intelligence** that gets smarter as our team grows This shift means our engineers will become AI orchestrators, not just coders, specializing in AI Engineering. They'll need to master: - **Foundation**: Understanding **foundation models**, model selection, and **prompt engineering**. - **AI application building**: Differentiating between **agents vs. workflows** and managing deployment and observability. - **AI-augmented software development**: Choosing the right tools (coding agents, IDEs, etc.), ensuring **context awareness** (runbooks, memory), and utilizing AI for review, testing, and refactoring within the development workflow. ### New service offerings We're expanding our **AI services** to include: - **AI engineering** for autonomous systems - **Agent system development** for complex workflows - **Multi-agent coordination** for enterprise operations ### Enterprise concerns and our architecture When we talk to enterprises about agentic AI, they want to understand both the concerns and the technical foundation. Here's what we're hearing and how we're addressing it: **Their concerns:** - **Data security** and on-premise deployment requirements - **Compliance** with industry regulations - **Integration** with existing legacy systems - **Control** over autonomous decision-making - **Transparency** in AI reasoning processes **Our architecture approach:** - **Foundational layer**: LLMs, LAMs, and SLMs that handle basic language and reasoning - **Knowledge layer**: Vector databases and knowledge graphs that organize information securely - **Adaptability layer**: Dynamic memory systems that adjust based on context while maintaining audit trails - **Autonomous agent layer**: The actual agents that coordinate and execute tasks with configurable oversight - **Integration layer**: APIs and interfaces that connect to existing enterprise tools without disruption ```mermaid flowchart TD subgraph integration["Integration Layer"] A1["APIs & Interfaces"] A2["Enterprise Tool Connectors"] A3["Security Gateways"] end subgraph agents["Autonomous Agent Layer"] B1["Task Coordination Agents"] B2["Decision Making Agents"] B3["Workflow Orchestrators"] end subgraph adaptability["Adaptability Layer"] C1["Dynamic Memory Systems"] C2["Context Management"] C3["Audit Trail Systems"] end subgraph knowledge["Knowledge Layer"] D1["Vector Databases"] D2["Knowledge Graphs"] D3["Information Security"] end subgraph foundation["Foundational Layer"] E1["Large Language Models (LLMs)"] E2["Language Action Models (LAMs)"] E3["Small Language Models (SLMs)"] end integration --> agents agents --> adaptability adaptability --> knowledge knowledge --> foundation style integration fill:#e3f2fd style agents fill:#e8f5e8 style adaptability fill:#fff3e0 style knowledge fill:#f3e5f5 style foundation fill:#f5f5f5 ``` These aren't just concerns. They're **opportunities** for us to solve if we want to sell these services effectively. Our layered approach ensures enterprises can deploy agentic AI without breaking their existing processes or compromising their security requirements. ## Our experiments We're not waiting for the market to mature. We're building our expertise through targeted experiments: - [x] **Smart social listening:** Actively monitoring and extracting insights from social signals to build our collective knowledge - [x] **MCP-Discord integration:** Building an interface for our team to interact with our agentic systems directly through Discord - [x] **Development toolchain:** Creating an AI-powered development environment that helps our engineers work more effectively in the age of AI agents - [x] **AI GenZ survey:** Vietnamese demographic analysis system that processes Vietnamese demographic data to create virtual profiles for Gen Z demographics - [ ] **Profile generator:** leverages AI to generate realistic, detailed user personas for various business scenarios including user research, marketing campaigns, and product development - [ ] **Window form automation:** Automating the creation and management of window forms for data entry and user interaction - [ ] **Agentic fortress:** Upgrading our current operational systems to AI workflows, from internal ops to project management - [ ] **Team knowledge base:** Routing all our data through a central intelligence system that gets smarter with every project - [ ] **Publication automation:** Using our knowledge base to generate more ideas and content for our communication strategy ## Reality check The market is moving fast. New agentic AI products are launching weekly, and we need to stay current with what's actually working versus what's just marketing. **Current market dynamics (updated regularly):** - **The coding agents race:** Everyone's competing to build better coding assistants (Cursor, Windsurf, Aider, etc.) - **Foundational model competition:** The race shifted from raw capability to specialized reasoning and action - **Enterprise adoption patterns:** Still slower than B2B SaaS, but accelerating in specific verticals - **Infrastructure vs. application layer:** Infrastructure providers seeing more sustainable traction - **Engineering career shifts:** Developers becoming AI orchestrators rather than pure coders **What we're actively tracking:** - Which coding agent frameworks are gaining real developer mindshare - How the foundational model landscape is consolidating or fragmenting - Enterprise security and compliance solutions that actually work - Where the biggest operational cost savings are being realized - How engineering roles are evolving with agentic AI adoption **Market signals we're watching:** - **Multi-agent coordination** becoming the default architecture - **API-first** approaches dominating successful implementations - **Specialized models** outperforming general-purpose ones in specific domains - **Human-in-the-loop** systems proving more reliable than fully autonomous ones We're not just following trends. We're building the expertise to **help our clients navigate this wave** while upgrading our own operations to stay competitive. The question isn't whether agentic AI will transform how we work. It's whether we'll be ready when it does.

2025 Roadmap

We're entering a pivotal year. 2025 is the year of agentic AI, where everything becomes automated and development costs plummet. Startups are racing to build agents that replace repetitive work, and we're positioning ourselves right at the center of this transformation. Our business model is straightforward: we sell our expertise, co-build with startups, help level up teams, and create custom solutions. But this year, we're doing it differently. ## Our focus areas for 2025 This year, we're betting big on four key areas: - **[AI engineering & agentic systems](/arc/on-agent)** - Building the future of automated workflows - **[Blockchain](/arc/on-blockchain)** - Powering decentralized solutions - **[Platform engineering](/arc/on-platform)** - Creating robust, scalable infrastructure - **[Spatial computing](/arc/on-spatial)** - Exploring new dimensions of user experience ## How we're organizing for success We've spent three years experimenting and refining our approach. Now we're ready to formalize our chair-based leadership model. Think of chairs as department heads with more flexibility. Each chair takes ownership of a specific area, brings AI expertise to the table, and has the freedom to make things happen. ### [Learning chair](learning-chair.md) Learning is our labs team. Their mission is simple: **pick up the newest tech, assess it, trial it, and then share it with the team**. This is critical to our identity as a [research-first](/updates/build-log/company), inbound-driven company. The learning chair will grow our labs team and boost our content production. We'll create materials in multiple formats for learning, publication, and communication. New initiatives: - Treasury allocation for labs team - Experiment-based approach with build-logs - AI Apprenticeship batch 2025 - Unlock: AI as copilot for everyone ### [Delivery chair]() Delivery is straightforward: we keep doing what we do best, but leverage new tech to **increase quality and ship faster**. Key questions we're answering: - How do we grow the delivery team? - How do we control quality at scale? - How do we measure delivery wins? ### [Communication chair]() We're doubling down on our research-first approach and **building our reputation** as an inbound engineering team. The goal is to use content from our learning team to build audience and attract talent. New directions: - Short video content for TikTok, Facebook, and YouTube - Vietnamese translations for broader reach - Developing our IP character for content consistency ### [Partnership chair](partnership-chair.md) Our go-to-market strategy leverages all the content and research from learning and communication to **spot opportunities**. Strategic partnerships: - [WALA](/updates/wala) with established companies to explore AI use cases - Partner with VCs to offer packages for AI startups - Work with CTOs and PMs on retainer projects, leading to platform ops opportunities ### [Engagement chair]() We're creating the best-in-class environment for our team. People need freedom to consult and co-build with partners while growing their skills. With new tech breakthroughs happening, we want **more peer engagement**. We're also opening up ownership opportunities for everyone. Key initiatives: - [Hybrid working](/handbook/hybrid-working) - back to office with flexibility - Gossip protocol for knowledge spreading - DFG earning system via contribution weight - New framework for talent recognition

Gossip protocol

Knowledge moves fast in tech. By the time you schedule a formal presentation, that breakthrough insight might already be old news. Our gossip protocol rewards the spontaneous moments when someone drops valuable knowledge in casual conversation. It's the missing piece between structured [knowledge sharing](sharing.md) and our [tech transfer framework](). While formal presentations have their place, some of the best learning happens in casual exchanges: "Hey, I just figured out a cleaner way to handle state management" or "That API issue? I found a workaround." The gossip protocol captures these moments, creates immediate positive feedback, and ensures valuable insights spread quickly without getting lost in the noise. ## How it works When someone shares useful knowledge in Discord, others can immediately reward them using our tip system. Instead of tipping from personal [ICY](icy.md) balances, they draw from our shared "gossip vault." The company funds the reward, not the individual. This creates a win-win: knowledge sharers get rewarded, receivers don't pay out of pocket, and valuable information spreads quickly through the team. ## The process Use `/tip @username amount` in Discord to reward valuable knowledge shares. Instead of spending your own ICY, you draw from our shared gossip vault. Our ops team reviews each request to ensure genuine knowledge sharing, then approves the ICY transfer within a few hours. ```mermaid flowchart TD A["Team member shares

Don't wait for the perfect moment. **Recognize value quickly**: Use the tip system when someone's knowledge helps you. Even small tips (5-10 ICY) matter. Include a brief message about how it helped. **Examples of good shares**: - "Just found out you can use `--dry-run` with that deployment script to test changes first" - "That React hook issue we discussed yesterday, turns out the dependency array was the problem. Here's what fixed it: [code snippet]" - "This debugging extension saved me 2 hours today: [link + brief explanation]" The gossip protocol makes knowledge sharing natural, immediate, and rewarding. In a world where information moves fast, teams that share knowledge quickly have a significant advantage. This system helps us become that kind of team, where everyone benefits when knowledge flows freely. --- > Next: [ICY Token](icy.md)

Tech transfer framework

As a tech-first consulting firm, our strength lies in turning cutting-edge research into game-changing solutions for clients. Our labs team produces innovative pilot experiments every tech wave across blockchain, AI, data, DevOps, and software construction. Meanwhile, our consulting team translates these ideas into real-world client success. But we've hit a challenge: **our research outputs are taking too long to reach the consulting team**. Text-heavy outputs from labs require significant effort from consultants to adapt for client projects. With 2-3 pilot experiments per tech wave across five domains, the volume and complexity can overwhelm our remote workflow. This gap impacts everyone: consultants spend extra time deciphering research outputs, labs work doesn't reach clients effectively, and clients miss out on our full expertise. This framework fixes that problem, empowering both teams to deliver better, faster results. Our pilots are the same [experiments we choose to build](../consulting/navigate/experiment.md) based on our market thesis. We call them "pilots" when focused on transferring knowledge to our consulting team. ## The framework: five parts to bridge the gap ### 1. Alignment: Focus pilots on client needs Make sure our pilot **experiments address real client pain** points while keeping all domains in play. Every tech wave, we hop on a 30-minute Discord call to score 2-3 pilots per domain. We rate them 1-5 on: client relevance, market buzz, and feasibility. This aligns with our [experiment selection process](../consulting/navigate/experiment.md) but adds the consulting angle. We'll create a quarterly "tech radar" on Memo - our "adopt, trial, assess, hold" map for experiments. One consultant and one labs person per domain become rotating "tech bridge leads." ### 2. Real-time collaboration through pilot pulse **Get consulting input** while labs is building, plus organic sharing that spreads. Create Discord channels (#blockchain-pilots, #ai-pilots, etc.) where labs posts drafts and questions, consultants provide feedback. Replace monthly calls with weekly 15-minute "pilot pulse" calls. Labs presents one pilot per domain in 5 minutes, then comes the magic: 2-minute "pilot spotlight" where a consultant shares a success story. Each pilot gets one consultant buddy (1-2 hours per week) to ensure real-world viability. ### 3. Consulting-ready outputs Transform pilot outputs into stuff consultants can pitch and deploy immediately. Labs creates a "consulting build-log" for each pilot on Memo: problem solved, use case, implementation steps, 2-minute demo video. These are the same [build-logs we already document](/updates/build-log) for our experiments. Convert seminars into 5-minute tutorials. Every pilot needs a working prototype stored in GitHub with clear READMEs. ### 4. Automated sharing and discovery Remove manual hunting for information. We auto-post new build-logs from Memo to Discord channels with AI summaries. Algolia search on Memo lets consultants find stuff by keyword. Prototypes are stored in GitHub with auto-testing Actions to ensure they actually work. ### 5. Continuous improvement loop Track what works, fix what doesn't. After consultants use a pilot, we can send quick feedback forms via Discord. Track "time-to-adoption" if possible. Spend time in pilot pulse calls discussing improvements. ## Challenges and how we'll handle them ### Labs team resistance to structured outputs Labs folks love exploring freely. Adding templates might feel restrictive. - Start small with one pilot per domain - Let labs choose which to "transfer-ify" first - Show impact through pilot spotlight stories - Keep core research unchanged ### Consultants too busy for collaboration Adding weekly calls and co-ownership might feel like extra work. - Keep calls short (15 minutes) - Record for async viewing - Limit co-ownership to 1-2 hours per week - Show direct value through client wins - Let consultants choose relevant pilots ### Measuring success and maintaining momentum Without clear metrics, the system might fade away. - Track simple metrics: time-to-adoption, pilots used in client work - Schedule monthly reviews - Celebrate wins publicly - Adjust based on usage data ## Your role in making this work **Consulting team**: Join pilot pulse calls, share client pain points, try one pilot per domain. Your feedback shapes research. **Labs team**: Create build-logs and prototypes, engage with consultants in Discord. Your work will directly impact clients. **Everyone**: Share pilot spotlight stories when you use a pilot. Let's close the gap together. This framework empowers you, whether you're in labs dreaming up ideas or in consulting delivering value to clients. --- Read more: [P2P sharing: gossip protocol](/handbook/gossip)

Choose what to build

```tldr Once we've formed a solid market thesis, the next step is choosing what to actually build. We use a simple priority framework: start with internal needs, then expand to startup ecosystem technologies and strategic assets. This keeps us focused and makes every experiment count. ``` You've spotted a promising tech trend. You've done the deep analysis. Your [market thesis](market-thesis-method.md) is solid. Now comes the crucial question: what do we actually build? This is where good ideas either become real value or get lost in endless possibilities. We've learned that having a clear decision framework matters more than having perfect ideas. ![](assets/market-thesis-method.png) ## How experiments fit our workflow Think of this as step 5+ in our market thesis method. Here's how it flows: **[News](growth-engine.md)** → **[Arc](/arc)** → **Experiment** → **Build-log** → **[Forward engineering](/forward-engineering)** - **Arc** is our term for each technology breakthrough we bet on - **Experiment** is each specific thing we decide to build within that arc - **Build-log** captures what we discover during the experiment - **Forward engineering** is how we report progress as a team snapshot When experiments are specifically designed to transfer knowledge from labs to consulting, we call them "pilots" and use our [tech transfer framework](/research/transfer). Same experiments, different focus: getting research insights to consulting teams fast. We're not building everything. We're making strategic choices about where to focus. ![](assets/report-workflow.png) ## Priority check With limited resources, we need to be strategic. Our priority is building up our edge and expertise to excel in consulting and staffing. ### 1. Serve internal ops (highest priority) Start with ourselves. Can we use this technology to solve problems we actually have at Dwarves? We become our own first customer, understand the problem deeply, and build real expertise through daily use. This gives us hands-on experience we can leverage when advising clients. If we can't make it work for ourselves, it's harder to convince others it's worth building. ### 2. Startup ecosystem technologies Focus on experiments that align with emerging technologies and startup ecosystem needs. This is where 80% of our business comes from: staffing and co-building with tech startups. We stay ahead of technologies the startup ecosystem is adopting. By building these ourselves, we develop expertise to either staff their teams or co-build solutions alongside them. ### 3. Long-term strategic assets These experiments focus on assets that can compound or yield more value with the least effort in the long run. They build our four core strengths: productivity, community, funding opportunities, and intellectual property. Will this asset continue working for us even when we're not actively maintaining it? Can it strengthen our community connections and compound our network effects? ### 4. Spin-off potential The best experiments can eventually become standalone products or services that grow beyond consulting into their own businesses. ## How we make the call Our experiments align with our business model: 80% of our revenue comes from staffing and co-building with tech startups at multiple scales. The remaining 10-20% comes from custom builds for traditional businesses. This means most experiments should build expertise that helps us: - Staff startup teams with people who know the latest tech - Co-build innovative solutions alongside startup founders - Stay ahead of technology trends our startup clients need When we want to move these experiments quickly to our consulting team, we treat them as pilots and apply our [tech transfer framework](/research/transfer) to accelerate adoption. We're not just building products. We're building the expertise that makes us valuable partners in the startup ecosystem. ![](assets/business-priority.png) **Example: DeFAI technology** After our market thesis identified DeFAI as promising, we had several options: - AI-powered smart contract auditing tool (internal ops) - Automated treasury management system (strategic asset) - AI oracle infrastructure (spin-off potential) We started with the treasury management system because we could use it internally first, it built our DeFi expertise, and it had clear spin-off potential. **The key insight:** We didn't try to build everything. We picked one experiment that checked multiple boxes and gave us the deepest learning. ## Resource reality check Each experiment needs to earn its place. We ask: - Can we build this well with our current team? - Will it teach us something valuable even if it doesn't succeed? - Can we complete a meaningful version in 8-12 weeks? Once we've chosen an experiment: 1. **Define the scope clearly:** What exactly are we building and why? 2. **Set learning goals:** What do we need to prove or discover? 3. **Plan the build-log:** How will we capture what we learn? 4. **Schedule the review:** When will we evaluate success? The goal isn't just to build something. It's to build expertise and create value that compounds over time. Each experiment feeds back into our market thesis. What we learn building one thing influences what we choose to build next. The key is staying in motion, building expertise, and making each experiment count toward our larger goals. --- > Next: [Test the water](test-the-water.md) or explore our [arc series](/arc) to see specific technology bets in action.

Understanding Tidewave.ai

Tidewave.ai is a development tool designed to enhance web application development by integrating AI assistants with your application's runtime environment. Below is a detailed breakdown to help understand its purpose, features, and functionality. ## What is Tidewave? Tidewave is a collection of open-source tools that connect AI assistants (e.g., Claude, GitHub Copilot, or Cursor) to your web framework's runtime through a **Model Context Protocol (MCP)** server. This allows AI to go beyond static code analysis and interact with your application in real-time, understanding its behavior, logs, database, and more. It's developed by **Dashbit**, the creators of Elixir and Livebook, and currently supports **Phoenix** (Elixir) and **Rails** frameworks, with plans for broader framework support. ## Key features 1. **Runtime intelligence**: - Tidewave runs an MCP server within your web app, enabling AI assistants to access runtime data like logs, database queries, WebSocket connections, or background jobs. This makes AI more context-aware, helping it debug errors or suggest code aligned with your app's actual behavior. - *Example*: You can ask the AI to check open WebSocket connections or execute a database query using your app's models. 2. **Integration with editors and AI tools**: - Tidewave integrates with editors (e.g., VSCode, Zed) and AI assistants that support MCP. You connect it by pointing your editor to the MCP endpoint (e.g., `http://localhost:4000/tidewave/mcp` for Phoenix). - It enhances AI tools like Claude Desktop, turning them into intelligent coding agents that can edit files, compile code, and fix errors automatically. 3. **Code execution and workflow automation**: - Tidewave allows AI to execute code within your project using tools like `project_eval` (for running code in your language's runtime) or `shell_eval` (for terminal commands). This streamlines tasks like validating APIs or running SQL queries without external tools. - You can define workflows in your preferred language (e.g., using a GitHub client library) and have the AI use them, keeping everything version-controlled. 4. **Security and configuration**: - Tidewave is designed for development, not production, and includes security features like restricting access to localhost by default or using Docker for isolation. - For Phoenix, you can configure options like `allowed_origins` to prevent cross-origin attacks or enable remote access if needed. 5. **Future plans**: - Tidewave aims to add **Page Intelligence**, a paid service to enhance AI's understanding of user interfaces and business logic. - It plans to support more frameworks and improve AI's ability to align code with business requirements, especially in testing and UI development. ## How it works - **Setup**: Add Tidewave to your Phoenix or Rails app. For Phoenix, modify your endpoint configuration to include the Tidewave plug, which runs the MCP server at a specific endpoint (e.g., `/tidewave/mcp`). - **AI interaction**: Your editor or AI assistant connects to this endpoint, allowing the AI to introspect your app's runtime. You can then issue commands like "add a pricing selector to my page" or "debug this error by checking logs." - **Example**: In a demo, José Valim (Tidewave's creator) used Claude Desktop with Tidewave to add a pricing selector to a Phoenix app. The AI edited files, compiled the project, and fixed syntax errors automatically, leveraging runtime context. ## Benefits - **Productivity boost**: Users report significant productivity gains, especially with tools like VSCode and GitHub Copilot, for tasks involving 30-100 lines of code across multiple files. - **Context-aware AI**: Unlike traditional AI tools that rely on static code, Tidewave's runtime access reduces errors (e.g., hallucinated functions) and makes suggestions more relevant. - **Open source**: The MCP server is open-source and available on GitHub, encouraging community contributions and transparency. ## Limitations and considerations - **Not for production**: Tidewave is explicitly for development environments due to security risks if exposed in production. - **Learning curve**: Configuring Tidewave and optimizing AI prompts (e.g., using "think" or specifying tools like `project_eval`) may require experimentation. - **Tool compatibility**: If your editor or AI doesn't support MCP, you may need an MCP proxy. Some users reported issues with free-tier AI tools (e.g., Claude in Zed) due to token limits. - **Early stage**: As of June 2025, Tidewave is still new (version 0.1.7), with some features like Page Intelligence not yet available. ## How to get started 1. Visit **tidewave.ai** for documentation and setup instructions. 2. Check the GitHub repositories for Phoenix (`tidewave-ai/tidewave_phoenix`) or Rails (`tidewave-ai/tidewave_rails`) to install Tidewave. 3. Follow the integration guide for your editor/AI tool, ensuring it supports MCP or uses a proxy. 4. Experiment with specific prompts to leverage Tidewave's tools (e.g., "use project_eval to test this API"). 5. Join the waitlist survey on their site to influence future framework support. ## Why it matters Tidewave bridges the gap between AI's textual understanding of code and the structured, runtime context of web applications. By giving AI access to your app's runtime, it enables smarter, faster development, aligning AI tools more closely with how developers think and work. ## References - [Tidewave.ai Official Website](https://tidewave.ai) - [Tidewave Phoenix GitHub Repository](https://github.com/tidewave-ai/tidewave_phoenix) - [Tidewave Rails GitHub Repository](https://github.com/tidewave-ai/tidewave_rails) - [Dashbit Announcement on Tidewave](https://dashbit.co/blog/tidewave-ai) (Assumed source for context, not directly accessed) - [X Post by @josevalim on Tidewave Demo](https://x.com/josevalim/status/XXXX) (Placeholder; specific post not provided in search results but referenced for demo context)

Generative engine optimization

## Snapshot view **Core mechanism:** LLMs do not crawl like search engines; they generate answers from their “memory” (model parameters). GEO optimizes content to be **semantically rich**, **contextually relevant**, and **easy for LLMs to parse**, so it gets **quoted inside AI answers**, not just listed on a results page. ## TL;DR - **Visibility = reference rate**: Track how often ChatGPT, Gemini, Claude cite you, not where you rank. - **Semantic richness & granularity**: Treat each paragraph as a standalone answer. Use summaries, bullet points, “In summary” hooks. - **E-E-A-T matters**: Demonstrate Expertise, Experience, Authoritativeness and Trustworthiness with bylines, case studies, data. - **Rapid iteration**: Major model updates can change extraction patterns overnight. Review weekly. - **Platform-specific seeding**: Reddit, YouTube, Quora dominate AI citations. Plant content where LLMs fish for answers. ![](assets/geo-key-concepts.png) ## What is generative engine optimization? - **Search is shifting from links to language models** Traditional SEO optimized for keyword-driven, link-based rankings. GEO optimizes for being cited inside AI answers, your content becomes part of the model’s “response,” not just an entry on a results page. - **Visibility = reference rate, not page rank** Instead of chasing high positions, GEO measures how often an LLM (ChatGPT/Gemini/Claude) references your content. In an AI-first world, will the model remember you? - **Longer, conversational queries** Users ask 20–30 word prompts; sessions span multiple turns and context carries over. Your content must be structured and semantically clear so the AI can lift it out as a standalone answer. - **E-E-A-T & trustworthiness matter** Models favor content demonstrating Expertise, Experience, Authoritativeness and Trustworthiness. Back up your points with author credentials, case studies or real-world data. (E.g: Showcase Dwarves Foundation’s expertise by highlighting author credentials) - **Business-model shift: Influence over impressions** Unlike ad-driven search engines, subscription-based LLMs only surface third-party content when it truly adds value. GEO becomes a game of influencing the model’s memory, not just earning clicks. - **Emerging GEO platforms & API-driven workflows** A new ecosystem (Profound, Goodie, Daydream, Semrush AI Toolkit) centralizes prompt testing, citation tracking, and dashboards integrate these via APIs to automate your deep-search experiments. - **How GEO differs from traditional SEO:** | **SEO (Traditional)** | **GEO (Generative)** | | --- | --- | | Ranking within a list of organic search results | Having AI models incorporate your brand/content into their final answer | | Focus on keywords, backlinks, page rank, click-throughs | Focus on language, content structure, semantic clarity, and reference rates | | Users click to visit websites | Users get answers directly, may not visit sites | | Keyword-based optimization | Language and context-based optimization | ![](assets/geo-key-concepts-claude-result.png) ## Core GEO signals & metrics **Reference rate** - % of representative AI queries that cite memo.d.foundation. **Structured content density** - Well-organized pages (headings, bullet lists, tables) packed with concise facts. **Outbound click volume** - When the AI answer links back, measuring those clicks shows real engagement beyond the model bubble. ## What should we do? ### For content writers 1. **Restructure every page** - Write a clear **“What you’ll learn”** 2–3 sentence summary at the top. - Break each topic into focused **bullet points** or **Q&A blocks,** treat each as its own answer. - Label key sections with headings like **Key takeaways, hot take** or **in summary.** 2. **Use semantic markup** - Ensure every tutorial or FAQ section is flagged for AI: - Wrap your steps in a “HowTo” block. - Wrap Q&A pairs in an “FAQ” block. ### For engineers / Technical team 1. **Build a deep-search pipeline** - **Query simulator**: Automate sending real-world prompts to LLM APIs (ChatGPT, Gemini, etc.) and record which pages or paragraphs are cited. - **Dashboard & alerts**: Feed those results into a monitoring dashboard (e.g., Grafana). Set alerts if a page’s reference rate falls below 10%. 2. **Enforce CI/CD guardrails** - **GEO linting checks**: In your build pipeline, run automated checks (e.g., GitHub Actions) to ensure every new page includes summaries, takeaways, and FAQ sections before it goes live. - **LLM preview tests**: On each content merge, trigger a quick API call with a standard prompt to confirm the new page surfaces correctly in the model response. 3. **Prompt engineering & fine-tuning** - **Prompt templates**: Provide a shared library of example prompts (e.g., “According to memo.d.foundation…”) for your LLM integration. - **Light fine-tuning**: If you run an internal LLM, periodically retrain it on your memo content so it more reliably surfaces your branding and phrasing. 4. **Optional edge-Lvel geo-targeting** - Deploy a small edge function (e.g., Cloudflare Worker) that reads visitor locale and injects localized snippets (“In Vietnam, best practice is…”) on memo pages to boost regional relevance. ## Why this matters - **AI-first discovery**: As LLMs become the primary research interface, being in the answer wins direct mindshare, no click required. - **Competitive moat**: Brands encoded into the AI layer gain lasting recall and preference. Raw impressions alone will not suffice. - **Inbound engine**: High reference rates drive organic traffic, community growth, and lead generation without relying on Google rankings. - **Business-model shift**: In subscription-driven LLM ecosystems, content surfaces only when it adds real value. GEO is about influencing model memory, not chasing clicks. - **Emerging GEO tooling**: Platforms like Profou, Goodie, Daydream, and Semrush AI Toolkit centralize prompt testing, citation tracking, and dashboards. Integrate them via APIs to automate deep-search experiments. *Source insight from: https://a16z.com/geo-over-seo/*

GEO and the future of knowledge: Who gets to be remembered?

> **TL;DR**: As generative AI engines take the wheel in deciding what we see, read, and remember, the question isn’t just about how to optimize for algorithms. The real question is whose stories survive the next wave of digital memory and whose fade away. ## When AI becomes the librarian AI models like ChatGPT and Gemini are the new librarians of the web. They decide which facts are surfaced, which sources get cited, and which voices echo across the digital landscape. But AI doesn’t make these choices in a vacuum. They learn from what’s already online, what’s popular, and what’s easy to parse. This means the loudest, most-linked, and most-optimized content rises to the top. Niche expertise, local knowledge, or unconventional perspectives risk getting buried. If you’re not in the training data, you’re not in the answer. ## The power and the problem of citation Reference rate is the new currency. If your work is cited by AI, you get noticed. If not, you might as well not exist. This changes the game for everyone: big publishers, indie creators, and communities working on the margins. When a user asks an AI a question, the model pulls from its training data and the live web. But not all sources are equal. Well-optimized, frequently cited content rises to the top. Smaller voices, niche communities, and non-mainstream perspectives risk fading into the background. But here’s the catch. AI models are trained on what’s available and visible. If your content isn’t structured for AI, or if you don’t play by the rules of GEO, your knowledge could slip through the cracks. The danger isn’t just being ignored. It’s being forgotten. ## Whose knowledge gets preserved? The web was supposed to democratize information. Now, we’re at risk of letting algorithms decide whose knowledge gets preserved and whose gets left out. Smaller voices, niche communities, and non-mainstream perspectives have always had to fight for visibility. With generative AI, the stakes are even higher. If a local historian’s blog isn’t cited by generative searching, does that knowledge survive? If a community’s lived experience never gets summarized in an AI answer, does it fade from collective memory? These are not just technical questions. This is about the future of what we know and who we listen to. ## What do we owe each other as stewards of knowledge? If you’re a writer, editor, or builder of digital spaces, you’re part of this story. The choices you make, what you publish, how you structure it, and who you cite decide what gets remembered. We should ask hard questions: - How do we make sure underrepresented voices aren’t erased by algorithmic convenience? - What can we do to keep the web weird, diverse, and surprising? - How do we balance optimization with authenticity? ## The stakes GEO gives us tools to surface knowledge, but it also gives us a responsibility. We can use our skills to lift up stories that might otherwise get lost. We can design for discoverability without flattening everything into the same template. If AI is the new librarian, let’s make sure its shelves aren’t missing the best, strangest, and most vital books. *Who gets to be remembered? The answer isn’t written yet. It’s up to us to make sure it’s not just the loudest voices, but the ones that matter most.*

Engineers in the AI landscape: architects, tinkerers, planners, and the vibers

The ground is shifting beneath our feet. If you're a software engineer and you're not feeling it, you're either lying or you're already obsolete. The introduction of powerful large language models is not just another tool; it's a fundamental paradigm shift that is cleaving the engineering world into distinct archetypes. I've noticed a few patterns emerge from the chaos. Understanding where you and your team fit in is the difference between building the future and getting buried by it. This isn't just about who can prompt an AI the best. It's about workflow, mindset, and the cognitive structures we use to build things. Your team is likely a mix of these new roles, and the friction you feel is the system trying to self-correct. Let's break them down. ## The AI-augmented architect ![pepe architect](assets/pepe-architect.png) This is the distinguished engineer who gets it. The architect sees AI not as a replacement but as a massive force multiplier, a ghostwriter for the tedious parts of creation. They operate at a high level of abstraction, feeding the model a well-defined structure and then reviewing the flood of code that comes back. They can manage this because they hold a mental map of the entire system in their head. Their value isn't in writing boilerplate; it's in their taste, their architectural vision, and their ability to conduct rapid, high-level code reviews. Their weakness: cognitive overload. The sheer volume of code an AI can produce is staggering. Reviewing tens of thousands of lines of code, even good code, is mentally taxing in a way writing it never was. It's a new flavor of burnout, born from the immense cognitive load of constant validation. They risk becoming a bottleneck, the sole validator of an AI's torrential output. How to cover for it: Aggressive automation and delegation are key. Architects need to offload the initial review process to automated systems. This means robust continuous integration/continuous deployment (CI/CD) pipelines with extensive automated testing suites - unit tests, integration tests, end-to-end tests. They must also empower other team members to become better reviewers by enforcing strict coding standards and documentation, potentially even using a linter AI to check for style and basic errors before the code ever reaches a human. They need to build a system of trust, but that trust must be verified programmatically. ## The tinkerer-turned-creator ![pepe tinkerer](assets/pepe-tinkerer.png) This is the person who always had great ideas but couldn't write the code to make them real. Now they can. The tinkerer uses AI as a manifestation engine. They are less concerned with the elegance of the codebase and more with the functionality of the output. They are masters of prompt engineering and rapid iteration, treating the AI as a black box and judging it solely by its results. They are bringing a flood of new, functional products and solutions to life that otherwise would have died as ideas on a whiteboard. Their weakness: technical debt and scalability. While their creations work, they often lack the robust architecture needed to scale or be maintained. They don't know what they don't know about design patterns, security vulnerabilities, or efficient database queries. Their projects are often a single bug away from total collapse, a house of cards built on "vibe-coded" slop. How to cover for it: Pair them with an architect or a methodical planner immediately. The tinkerer is an incredible source of innovation, but their output needs to be refined and hardened by someone with deep systems knowledge. Implement a mandatory architectural review before any project by a tinkerer goes into production. Give them a "sandbox" environment where they can build and break things without consequence, but have a formal handoff process to a senior engineer who can rebuild the prototype correctly for production. The goal is to harness their creativity without inheriting their technical debt. ## The methodical planner ![pepe planner](assets/pepe-planner.png) This engineer is the antithesis of the "move fast and break things" mantra. They understand that with AI, moving fast is easy, but moving in the right direction is hard. They spend an enormous amount of time on planning, structuring, and testing before they even let the AI start generating code. They build intricate scaffolding of requirements and tests that forces the AI's output to conform to a high-quality standard. They are building massive, stable systems by treating the AI not as a creator but as a hyper-efficient subordinate that executes a very detailed plan. Their weakness: analysis paralysis. The methodical planner can become so obsessed with creating the perfect plan that they slow down innovation to a crawl. They can miss market opportunities or fail to pivot quickly because their entire workflow is built around a rigid, upfront structure. They risk designing a perfect system for a problem that no longer exists by the time they're finished. How to cover for it: Force them into an agile framework. Planners need to work in sprints with concrete, unmovable deadlines. Their detailed plans should be for the next two weeks, not the next two years. Pair them with a tinkerer to inject a sense of urgency and user-centric chaos into their process. The goal is to get the planner to build the minimum viable plan necessary to get started, and then iterate. Celebrate shipping a functional 80% solution over planning a perfect 100% solution that never gets built. ## The "vibe coder" ![pepe viber](assets/pepe-viber.png) This is the most dangerous archetype. This engineer is seduced by the promise of fully autonomous agentic code generation. They point the AI at a problem, press "go," and hope for the best. They are thrilled by the initial burst of activity but quickly find themselves with a sprawling, incomprehensible codebase that is impossible to debug. They have completely abdicated their responsibility as an engineer and have no mental map of the project. They are not managing the AI; they are being managed by it, stuck in a frustrating loop of generating, testing, and failing. Their weakness: everything. They produce unmaintainable, buggy, and insecure code. They have no understanding of the systems they are creating and are a massive liability to any serious project. This isn't a workflow; it's a slot machine. How to cover for it: This is a rescue mission. The unguided vibe coder needs immediate, intensive re-training. They must be banned from using agentic workflows and forced back to basics. Mandate that they write code manually, or at the very least, use AI in a co-pilot capacity where they are writing and reviewing every single line. Pair them with a methodical planner to learn the discipline of structured development. Their access to AI tooling should be restricted until they can demonstrate a fundamental understanding of the systems they are building. Sometimes the best way to use a new tool is to first remember how to work without it. ## A balanced system The critical skill now is not just mastering AI tools, but mastering yourself. You need to honestly assess whether you're an architect, a tinkerer, or a planner and then aggressively mitigate the inherent weaknesses of that archetype. The real goal isn't to become some mythical, perfect engineer who embodies all of these traits. That person doesn't exist. The goal is to build a team that does. A team composed of a planner to lay the foundation, a tinkerer to drive rapid innovation, and an architect to ensure it all scales is a force of nature. The unguided vibe coder serves as a cautionary tale of what happens when you let the tool become the master.

How we craft a market thesis

```tldr We've built a five-step method to spot tech trends worth betting on. It mixes data, gut feel, and our team's strengths to find opportunities that actually matter. Here's how we do it. ``` ## Why we need a system The tech world never stops moving. One day it's DeFAI (AI-driven DeFi), the next it's spatial computing. Pick the right trend and you're golden. Chase every shiny thing and you'll waste time and money. We needed a way to make smart bets. Something that aligns new opportunities with what we're good at and the four things we care about: boosting productivity, building communities, engineering liquidity, and creating IP. This is how we figured it out. ## Our five-step approach We've tested this method on everything from Golang to blockchain. It balances hard data with experience, and it works for a scrappy consulting team like ours. ![](assets/market-thesis-method.png) ### 1. Spot the pulse We start by finding tech "pulses" - early signals that something big might be coming. This isn't just guessing. We use both data and instinct. **What we look for:** - Hiring trends and funding news from our growth engine - Chatter on X and in VC reports - What the smart folks are building in niche communities Take DeFAI. We saw $500M flowing into AI-blockchain startups in 2024. Then we noticed DeFi developers on X talking about LLM-driven interfaces. That's a pulse worth exploring. **How it works:** We scan for stuff that solves real problems or could shake up markets. Cross-reference the numbers (like 10x growth in DeFAI usage) with what people are actually saying. ### 2. Dig into the tech Once we spot something interesting, we dive deep. We need to understand what makes it tick and where it might break. **Our analysis covers:** - **Where it came from:** Why did this tech emerge? For DeFAI, it's DeFi's $180B market hitting LLM breakthroughs post-2020. People wanted better UX and automation. - **How it works:** The nuts and bolts. Smart contracts in Solidity, consensus mechanisms, AI compute platforms like Bittensor. - **What it does well:** DeFAI nails UX and automation efficiency. - **What it sucks at:** High compute costs and transparency issues. - **Biggest challenges:** Scalability and security for AI models. - **Real limitations:** Still mostly appeals to crypto folks. **Why this matters:** Understanding the mechanics helps us spot real opportunities versus hype. For DeFAI, we learned it simplifies DeFi but costs about $50,000 per LLM model to train. ### 3. Find the right people and industries Not every trend works everywhere. We focus on industries and people where the tech can actually create value, especially in our four verticals. **How we choose:** - Market size and growth potential - Where our network reaches - Alignment with our strengths For DeFAI, we targeted finance folks (DeFi developers), tech teams (blockchain engineers), retailers (e-commerce platforms), real estate (tokenization), and healthcare IT. **The key:** We identify specific pain points these people have. High payment fees for retailers. Complex development for engineers. Stuff the new tech can actually fix. ### 4. Match solutions to problems Here's where we connect what the tech can do with what people actually need. We explore both user-facing apps and developer tools. **Our approach:** - Test it ourselves first to build expertise - Map capabilities to pain points for each target group For DeFAI, we used AI-integrated smart contracts for our own treasury management. Then we brainstormed how LLM-driven interfaces could help retailers accept crypto payments more easily. **What this gives us:** Real hypotheses about where we can create value. Like mapping AI oracles to finance developers who need real-time data feeds. ### 5. Generate ideas and make plans Time to get creative, then get practical. We come up with solutions, pick the best ones, and plan how to build them. **Our process:** - **Brainstorm:** 3-5 high-impact solutions per industry, both apps and infrastructure - **Filter:** Evaluate based on revenue potential, strategic fit, and how hard it is to build - **Plan:** Outline objectives, features, and steps, starting with MVPs For DeFAI, we proposed an AI investment app (for users) and a smart contract AI integration kit (for developers). We prioritized the developer kit because it fits our strengths and has clear market demand. **The result:** Actionable projects we can actually execute. Like our smart contract kit with LLM integration, tested on Arbitrum. ## How we built this method This didn't happen overnight. We learned from years of betting on tech trends, some good, some not so much. **Early days:** We started with gut feelings. Mobile apps in the 2010s, Golang adoption. When we combined data (hiring trends) with community signals, we did well. **Learning from mistakes:** Bets like Fuchsia OS and Elixir didn't work out. Wrong timing, poor market fit. Taught us to check if the ecosystem is actually ready. **Refining with DeFAI:** Analyzing AI + DeFi in 2025 helped us nail down our approach. We added the origin layer to understand why trends emerge. Started focusing more on infrastructure solutions to use our technical skills. **Constant improvement:** Every thesis teaches us something. Golang's community-driven success showed us to watch social signals. DeFAI confirmed we need both technical depth and balanced thinking about apps versus infrastructure. The method crystallized into something structured but flexible. Data plus intuition plus strategic alignment with what we're good at. ## How it works: The DeFAI example Let's walk through how we applied this to DeFAI: 1. **Spotted the pulse:** $500M in AI-blockchain funding plus X chatter about LLM-driven DeFi interfaces 2. **Analyzed the tech:** Studied how DeFi's UX problems meet AI advances, strengths (automation), weaknesses (cost) 3. **Found our people:** DeFi developers, retailers, healthcare IT teams aligned with our productivity and liquidity focus 4. **Mapped solutions:** Matched DeFAI to real problems like complex development (solved by AI SDKs) and high payment fees (solved by layer-2 AI payments) 5. **Made plans:** Proposed specific solutions like an AI investment app and smart contract AI kit, with MVPs to test internally first This positioned us to tap into DeFAI's projected $10B market by 2025 with stuff we can actually build. ## Why this works Our method succeeds because it's: - **Smart about data:** Uses hard numbers plus experience to spot early trends - **Strategically aligned:** Ties everything back to our four verticals - **Resource-conscious:** Focuses on high-impact, doable solutions for a small team - **Always learning:** Gets better with each bet we make ## What's next We're testing this approach on spatial computing and advanced AI automation. By trying things internally first and sticking to our strengths, we'll keep building solutions that matter. This methodology helps us build solid assumptions about what to create in our [arc series](/arc), where we explore specific tech trends and their potential applications. Once we have these assumptions, we use our [experiment selection framework](experiment.md) to choose which ideas to actually build. --- > Next: [Choose what to build](experiment.md) or [Test the water](test-the-water.md)

Vibe culture

**AI handles the technical complexity, humans focus on the vibe.** This division of labor represents a fundamental shift in how we approach creative work, but also signals growing reliance on AI systems for basic functionality. ## What vibe culture looks like Vibe culture prioritizes emotional resonance over traditional structured approaches. The process starts with AI handling technical foundations, then creators layer on feelings and aesthetics. Developers describe apps that "feel futuristic," designers create projects with "lo-fi aesthetics," marketers craft "cozy, authentic vibes." AI tools like Cursor, Figma, and ChatGPT first generate the functional scaffolding. Users then refine and customize based on desired emotional outcomes rather than technical specifications. This delegation allows non-technical creators to produce professional results while focusing energy on creative decisions. However, this convenience creates dependency. Creators increasingly rely on AI for tasks they might have learned themselves, from basic coding to design principles. The ease of AI assistance can discourage deeper technical understanding. ## Why this approach emerged AI's technical capabilities created space for human creativity to flourish. When machines handle coding, design systems, and content generation, humans can concentrate on strategic and emotional aspects. The approach offers immediate gratification through rapid prototyping while preserving creative control. Social platforms reward emotional engagement over technical precision, reinforcing this division of labor. Each AI-generated foundation provides a starting point for creative exploration, creating positive feedback cycles that make the process feel effortless and enjoyable. This reliance also reflects changing skill expectations. As AI handles technical execution, human value shifts toward curation, direction, and emotional intelligence. The market increasingly rewards those who can guide AI effectively rather than execute tasks manually. ![](assets/the-new-problem.png) ## How to leverage AI-enabled creativity Effective vibe culture treats AI as infrastructure rather than replacement. Let AI handle technical heavy lifting, then apply human judgment for emotional resonance, user needs, and strategic alignment. This approach maximizes both efficiency and creative quality. Use AI to generate initial concepts, code frameworks, or design systems. Then focus human effort on refining user experience, brand alignment, and meaningful problem-solving. The key is maintaining core competencies while leveraging AI efficiency. Consider the long-term implications of AI reliance. Develop understanding of underlying principles even when delegating execution. This ensures you can evaluate AI outputs critically and maintain creative control when AI tools fail or change. *Source: Insights from [Ian Batterbee's UX Design article](https://uxdesign.cc/everythings-a-vibe-is-it-progress-or-just-an-illusion-fcd32b2844bb).*

Design tokens in the AI era

**Design tokens are the shared language between designers and developers.** These platform-agnostic variables store visual attributes like colors, typography, and spacing, ensuring consistency across web, mobile, and other platforms. AI tools now automate much of the heavy lifting in token creation and management. ## What design tokens accomplish Design tokens fall into two categories: global tokens (`blue.default` for a color) and semantic tokens (`button-primary` for context-specific use). They centralize design decisions in JSON files or similar formats, eliminating hard-coded values throughout codebases. This approach enables rapid updates across platforms. Change one token value and every instance updates automatically. Teams can implement theming systems, like light and dark modes, by swapping token sets. The result is fewer errors, faster development, and unified visual consistency. ![](assets/design-token.png) ## Why AI transforms token workflows AI tools analyze design files from Figma or Sketch, automatically generating tokens for colors, fonts, and spacing. This eliminates hours of manual extraction work. AI suggests semantic token names based on usage patterns, creating intuitive labels like `text-secondary` for gray caption text. Modern AI systems also handle distribution. An AI agent can detect token changes in design files, update code repositories, and trigger deployment pipelines automatically. This ensures real-time consistency across all platforms without manual coordination. ## How to implement AI-powered tokens Start with tools like Style Dictionary for token management or Figma plugins with AI integrations. These platforms streamline initial setup and ongoing maintenance. For non-designers, AI-powered natural language interfaces allow updates through simple commands like "make buttons darker." However, maintain human oversight. AI can suggest accessibility improvements for WCAG compliance or generate dynamic themes, but teams should validate outputs against brand guidelines and user needs. The goal is leveraging AI efficiency while preserving creative control and design quality. AI makes design tokens more accessible, but the fundamental value remains human-centered design decisions executed consistently at scale.

Most engineers can't actually engineer

Here's something we don't talk about enough in our industry: most of what we call "engineering talent" has very little to do with actual engineering ability. We've built this whole mythology around coding speed. We worship the 10x programmer, obsess over leetcode performance, and measure everything in story points. But here's the thing, the real divide in engineering isn't about how fast you type. It's about capability. Some engineers can solve problems that others literally cannot solve, no matter how much time you give them. And that's not a popular thing to say, but after years of building teams and watching projects succeed or fail, it's impossible to ignore. ## The capability cliff Think of engineering talent like a mountain range, not a gentle slope. Most people assume engineering skill works like a spectrum. Junior folks work slower, senior folks work faster, and everyone can eventually figure out any problem given enough time. That's completely wrong. **Here's what actually happens:** There are fundamental capabilities that create hard boundaries between engineers. Either you can debug a complex race condition across multiple services, or you can't. Either you can ship a project that requires architectural changes, or you can't. Time doesn't bridge these gaps. I've watched engineers spend weeks on problems that others solve in hours. Not because they're slow, but because they lack the mental models to even approach the problem correctly. ## Three types of engineers you'll meet ### Strong engineers tackle the impossible stuff These are the folks who don't just write code, they solve the problems that break everyone else. They can: - Debug issues that span multiple systems and involve timing problems - Refactor legacy code without everything exploding - Ship complex features that need coordination across teams - Turn vague business requirements into working software - Make architectural decisions that actually scale **What makes them different:** They think in systems, not just code. When someone says "make it faster," they don't start randomly optimizing functions. They figure out what "faster" actually means, find the real bottleneck, and solve the right problem. ### Regular engineers keep things running These engineers form the backbone of most teams. They handle: - Normal bugs that follow predictable patterns - Well-defined feature work with clear requirements - Standard dev environment issues - Code reviews and documentation These folks are genuinely valuable. They ship features, fix bugs, and keep systems running reliably. You can count on them to deliver what they commit to, on time and with solid quality. They're not trying to revolutionize anything, they're just doing good, consistent work. ### Weak engineers struggle with the basics This is the uncomfortable part. Some engineers literally cannot complete basic engineering tasks, even after years in the industry. **How they survive through what I call "ghost engineering":** - Constant "pairing" where they do none of the actual work - Always asking questions in meetings without contributing insights - Taking credit for collaborative work where others did the heavy lifting - Creating elaborate processes to avoid actual implementation **The real issue:** They lack problem-solving patterns. They can't break down complex problems, can't form hypotheses about what might be wrong, and can't work systematically toward solutions. ## Why some engineers improve and others don't The difference isn't about experience or training. It's about how people approach problem-solving. **Strong engineers:** - Form hypotheses and test them systematically - Build mental models of how systems behave - Can work with incomplete information - Learn from failures and adjust their approach **Weak engineers:** - Try random solutions hoping something works - Don't understand the systems they're working with - Need complete specifications for even simple tasks - Repeat the same mistakes without learning This explains why some engineers improve rapidly while others plateau, no matter how much time you invest in their development. ## Working with different types **With weak engineers:** - Protect your time. Don't do their work for them - Document everything clearly when you do help - Alert management if someone consistently can't complete basic tasks - Don't enable ghost engineering patterns **With regular engineers:** - Give them clear, well-defined problems - Provide good documentation and context - Recognize and reward their consistency **With strong engineers:** - Give them the hardest, most ambiguous problems - Let them shape technical direction and architecture - Use them to mentor and develop others ## Figuring out where you fit **Strong engineers** know they're strong. They're the ones teammates come to with hard problems. Others seek their technical opinions and trust their judgment. **Regular engineers** complete their work reliably and have areas where they're the go-to person on the team. **Weak engineers** often think they're stronger than they are. If you're constantly asking for help, always struggling with basic tasks, or finding excuses for incomplete work, you might be in this category. ## What this means for your career **If you're strong:** Focus on problems only you can solve. Mentor others, but don't do their work for them. **If you're regular:** Get exceptionally good at your strengths. Develop deep expertise in specific areas. **If you're weak:** Either develop real engineering capabilities through honest practice and self-assessment, or consider a different career path. **For companies:** Structure teams that use each type appropriately. Don't expect weak engineers to become strong ones with more time or training. ## The honest truth Engineering talent was never evenly distributed. Some people can build systems that scale, others can't. Some can debug complex problems, others get stuck on simple issues. The teams that acknowledge this reality and organize accordingly build better software more efficiently. Those that pretend all engineers are interchangeable keep struggling with predictable results. It's not about being mean or elitist. It's about being realistic so everyone can do their best work in the right role.

What makes a strong engineer in the AI era

**The software industry has a hiring problem.** We've spent decades optimizing for algorithmic wizards who can reverse binary trees in their sleep, while completely ignoring the skills that actually matter for building great software. Now, with AI agents writing code faster than any human, this misalignment isn't just inefficient, it's existential. The concept of "weak engineers" exposes what many already knew: technical skill alone doesn't make someone effective. Engineers share stories of brilliant coders who couldn't communicate, couldn't think strategically, and couldn't deliver real value. In the age of AI, these problems aren't just annoying anymore. They're existential. ## What we got wrong about engineering A "weak" engineer excels at technical tasks but struggles with broader skills needed for impactful software. They crush algorithmic interviews and memorize design patterns, but can't grasp trade-offs, communicate with stakeholders, or align work with business goals. Our entire hiring process selects for this profile. We test candidates on problems they'll never solve while ignoring skills they'll use daily. **The AI twist:** Now that coding agents generate boilerplate code, implement algorithms, and suggest system designs, pure technical skill matters less than ever. What matters is knowing what to build, why to build it, and how to guide AI tools toward the right solutions. A "weak" engineer in the AI era blindly accepts AI outputs without questioning correctness, security, or business fit. They let GitHub Copilot write database schemas without considering scalability, or implement AI-suggested features without understanding trade-offs. ## Critical thinking becomes essential Critical thinking has long been undervalued compared to pure technical skills. In an AI-driven world, this becomes essential for survival. **Why AI makes this urgent:** AI agents excel at executing well-defined tasks but struggle with ambiguity. When stakeholders say "make the app faster," AI can't figure out what that means. Strong engineers bridge this gap by translating vague requirements into clear instructions and ensuring solutions solve the right problems. Consider building an AI-driven recommendation system. Your coding agent might generate algorithms that maximize click-through rates. A weak engineer implements them directly. A strong engineer asks: Do these algorithms respect user privacy? Will they scale cost-effectively? Do they align with our brand values? ## Communication: your unfair advantage Communication is critical for collaboration and business alignment, yet it's often ignored in favor of coding skills. The AI era makes this even more valuable. Engineers increasingly act as bridges between AI capabilities and business strategy. They must craft precise instructions for AI tools, explain AI-generated solutions to non-technical stakeholders, and justify why they modified or rejected AI suggestions. Strong engineers use communication as their competitive advantage in an increasingly automated world. ## Hiring needs to evolve Current hiring practices are broken. LeetCode problems that AI can solve in seconds tell us nothing about candidates' ability to work with AI tools or make strategic decisions. **AI-era hiring should include:** - Giving candidates AI-generated code to critique for performance, security, or business alignment - Pair programming sessions with AI collaboration - Testing system design skills with AI assistance - Evaluating how candidates refine and improve AI outputs The goal isn't eliminating technical assessment. It's testing technical judgment rather than technical memorization. ## What strong engineers look like now In the AI era, strong engineers are orchestrators, not just implementers. They guide AI tools toward business goals, translate ambiguity into clarity, evaluate trade-offs AI can't understand, and communicate across disciplines to align technical decisions with business strategy. They're not necessarily the fastest coders. They're people who see the bigger picture and use AI to achieve it. ## The path forward The shift is already happening. Companies that adapt their hiring, training, and culture will attract engineers who thrive in AI-augmented workflows. **For individuals:** Focus on developing judgment, communication, and strategic thinking. Learn to work with AI tools rather than competing against them. **For companies:** Rethink what you value and test for. Hire for potential impact, not just technical performance. **For the industry:** Build more diverse, thoughtful teams that deliver real value rather than just impressive algorithms. The age of the "10x engineer" who cranks out code in isolation is ending. The future belongs to engineers who can think critically, communicate clearly, and orchestrate AI to solve meaningful problems. *Sources: Insights from [Sean Goedecke's "Weak Engineers"](https://www.seangoedecke.com/weak-engineers/) and [Hacker News discussion](https://news.ycombinator.com/item?id=42520482).*

Do one thing well

**The best products do one thing exceptionally well.** This isn't just a nice-to-have philosophy, it's the foundation of sustainable product development. Rooted in the Unix tradition of small, sharp tools, this mindset offers a powerful alternative to the bloated, everything-and-the-kitchen-sink approach that plagues modern software. As we move into an era of agentic AI and rapidly evolving technology, the principles behind `grep`, `curl`, and `jq` become more relevant than ever. These tools succeed because they focus, compose, and integrate seamlessly. Your products and AI systems should too. ## The Unix way Small, sharp tools are lightweight programs that excel at a single task. They embody Doug McIlroy's 1978 philosophy: "Write programs that do one thing and do it well." These tools share key characteristics: - **Focused scope:** They solve one problem completely rather than many problems partially - **Composable design:** They work together through pipes, APIs, or standard interfaces - **Clear boundaries:** They avoid feature creep and unnecessary complications ## Why this matters now **Products stay maintainable:** When your note-taking app tries to be a calendar and task manager, everything suffers. When it focuses on fast, distraction-free writing, it excels. **Teams move faster:** Small, scoped features ship quickly. You can validate assumptions and iterate without managing monolithic complexity. **Users understand value:** Stripe focuses on payments, not accounting. Calendly handles scheduling, not project management. Clear value propositions win. **Systems integrate better:** Products designed as focused tools integrate seamlessly through APIs and standard formats, enabling users to create custom solutions. ## Agentic AI applications This philosophy becomes crucial for AI systems: - **Specialized agents:** Create focused agents that excel at specific tasks rather than generalist AIs that do everything poorly - **Composable workflows:** Design agents to work together through clear interfaces, like Unix pipes for AI - **Clear failure boundaries:** Narrow scope makes AI limitations predictable and manageable ## How to build this way - **Define clear boundaries:** Use jobs-to-be-done frameworks to identify core purpose - **Design for composition:** Build with APIs and standard formats for integration - **Resist scope creep:** Ask whether new features serve the core purpose - **Start minimal:** Launch with the smallest viable feature that delivers value The future belongs to products and AI systems that do one thing exceptionally well and compose beautifully with others. In a world of infinite possibilities, focus becomes your competitive advantage. *Sources: Adapted from "Small, Sharp Tools" by Brandur Leach, [brandur.org](https://brandur.org/small-sharp-tools), December 12, 2014.

What's new in May 2025

May was the month we finally shipped the stuff we've been promising ourselves for ages. You know that feeling when you've been talking about reorganizing your desk for months, and then you actually do it? That's what happened with Memo, MCP Playbook, and honestly, how we work as a team. **Major updates:** - [**Memo got rebuilt with contributor profiles and on-chain proof**](#memo-ui-overhaul-and-contributor-system-cleaned-up): New homepage, updated TOC, sidebar redesign, visible author info, and NFT minting support. Memo now reflects how we work and who's writing. - [**MCP Playbook became operational**](#mcp-playbook-now-powers-how-we-document-and-log-project-work): Delivery folders now follow structured patterns (docs/, adr/, .chat/), and tools like observer-log and save_and_upload_chat_log work in real projects. - [**Consulting inquiries picked up significantly**](#consulting-work-became-a-testing-ground): More client interest flowing in compared to early year, with team members like @minhlq and @hieuvd joining client calls and learning the shift from pure engineering to business-focused consulting. - [**35+ new entries published across engineering, ops, consulting**](#content-ownership-habits-changed-internally): Covering everything from internal tooling and documentation to growth loops and consulting alignment. **Supporting systems:** - [**Prompt DB became the team's shared brain, and PromptKit entered prep**](#promptit-and-prompt-db-entered-the-pipeline): Centralized prompts for writing, debugging, and research with version control. PromptKit adds syncing and repeatable usage patterns. - [**Observer-log bridged Discord and knowledge base**](#observer-log-now-active-on-discord): We shipped an internal Discord bot to quietly collect discussions, terms, and link drops. It's the foundation of a lightweight reporting layer. - [**Live demos of vibe coding and MCP Discord integration**](#live-demos-of-mcp-discord-integration-and-ai-assisted-development-workflows): Real-time sessions showed AI-first development workflows from planning to implementation, plus team knowledge base querying through Discord bot integration. - [**Forward Engineering: May edition**](#capturing-engineering-decisions-through-mcp-builds-and-publishing-infra): Shipped updates include MCP client builds, static site infra, Memo quality pipeline, and site build strategy documentation. ![thumbnail](assets/2025-whats-new-may-thumbnail.png) ## Memo UI overhaul and contributor system cleaned up The biggest shift this month is the new Memo interface. The homepage now reflects what we're actually publishing. Sidebar structure was updated to highlight real usage flows. Topic folders are no longer buried. Memo now feels like a proper working wiki, not just a dumping ground. - Table of contents structure was revised to reflect reading intent. - Contributor names are now visible at the top of each post. This small tweak changed internal habits. More people now care about what they publish. - We cleaned up visual consistency and spacing between sections, making browsing smoother. - On-chain NFT minting now works for every published memo with a verified wallet. Minting is optional but adds visibility and ownership tracking. - Tags and topic routing were made more reliable so content doesn't get lost in the archive. - A dozen system-level articles were added to explain how Memo actually works: architecture, build log, deployment, static site choices, Git submodules, and more. Here's a list of documents detailing the development of Memo: https://memo.d.foundation/build-log/memo/ ### Content ownership habits changed internally Publishing workflows shifted from individual efforts to integrated team processes. - With clearer contributor visibility and article grouping, publishing is starting to feel less like a side-task and more like part of our workflow. - Contributors now regularly track from ideation to final drafts, helped by better publishing tooling and contributor listing features on Memo. ![](assets/2025-whats-new-may-memo.png) ## MCP Playbook now powers how we document and log project work - The MCP server ecosystem grew throughout May. Discord integration, database queries, GitHub automation, file processing. Each server handles specific workflows our team uses regularly. - Chat logs sync to the right places without manual copying. Discord webhook integration captures insights from tech channels and stores them as searchable knowledge blocks. - Used to structure delivery folders with /docs, /specs, /adr, and .chat directories. - Early team usage shows tools like observer-log and save_and_upload_chat_log working well. - Prompt syncing to prompt-db and changelog generation now feel more integrated with project flow. → Repo: [MCP Playbook](https://github.com/dwarvesf/mcp-playbook) ## Consulting work became a testing ground Consulting inquiries picked up significantly in May compared to early year. More interesting than the volume increase was how we approached these projects differently. Team member like @minhlq started joining client calls, learning the shift from pure engineering to business-focused consulting. The challenge isn't technical complexity - it's learning to understand what clients actually need versus what they initially request. As @minhlq put it during our community call: "You have to guess what they really want. Sometimes they don't even know themselves." This requires a completely different skill set from traditional development work, shifting perspective from pure technical focus to understanding business value and client success metrics. Instead of treating consulting as separate from research work, we're using client projects to validate and refine the tools we're building. ## Article contributions picked up across ops, engineering, and consulting Content output reached new levels with broader team participation across all functions. More than 35 memos were published this month, spanning: - System and infra decisions (Makefiles, static sites, Git submodules). - Product and consulting patterns (growth loops, agency structure, client-side vs team-side models): https://memo.d.foundation/consulting/ - Operational thinking (wealth studies, engagement models, planning frameworks): https://memo.d.foundation/handbook/ - Forward-thinking topics like inefficiency arbitrage, market cycles, and delivery signals → Browse all: [memo.d.foundation/updates](http://memo.d.foundation/updates) ## Promptit and prompt-db entered the pipeline We moved prompt management from ad-hoc sharing to structured systems and version control: - PromptKit prep work began with content structure planning and internal syncing systems set up. - prompt-db now lists operating prompts, templates, and synced prompts to help teams write and track more repeatable LLM patterns. - The repo doubles as both a prompt library and version history for how prompt thinking evolves over time. → Repo: [Prompt DB](https://github.com/dwarvesf/prompt-db) → Memo: https://memo.d.foundation/prompts/ ![](assets/2025-whats-new-may-promptdb.png) ## Observer-log now active on Discord We deployed automated knowledge capture to track team discussions and shared resources. - Our new Discord-based bot now logs tech activity, from shared links to concept discussions. - Captures key context like terms, timestamps, and summary insights without disrupting team flow. - Feeds into our internal reporting and documentation structure, acting as a passive knowledge collector. → Join our network and check it out at **👓・observer-log**: [discord.gg/dfoundation](http://discord.gg/dfoundation) ![](assets/2025-whats-new-may-observerlog.png) ## Live demos of MCP Discord integration and AI-assisted development workflows In our last community call included live demos that showed the tools in actual use, we proved our tools work by using them live during the community call. Real queries, real implementations, real feedback when things didn't work perfectly. **MCP Discord bot querying team knowledge base:** - Real-time querying of team knowledge base through Discord interface. - Search functionality across prompt databases and documentation repos. - Integration with multiple MCP servers (Playbook, GitHub, Context7). - Live data retrieval showing actual response times and query results. - User management with encrypted API keys and authorization headers. **Complete planning workflow with AI:** - Live coding session from initial brief to implementation using Gemini 2.5. - Automated generation of overview.md and feature.md specification files. - Project structure documentation using tree commands for context loading. - MCP Playbook integration creating ADRs, changelogs, and specification templates. - Real-time context building with 25+ tool calls for comprehensive understanding. - Document-first approach showing planning before coding implementation. These were working sessions that showed both what works and what still needs improvement. When the bot took time to initialize or queries didn't return perfect results, that provided valuable feedback for the next iteration. ## Capturing engineering decisions through MCP builds and publishing infra We shipped the May edition of [Forward Engineering](https://memo.d.foundation/updates/forward/2025-05/), covering internal experiments like: - Building MCP clients for Discord. - Streamlining site deployment with Makefile. - Memo quality pipelines and Git submodule structure. The radar this month included key developments: MCP ecosystem expansion, agent-first workflows, vibe-coding approaches, and AI-powered IDE trends. Microsoft's decision to open-source VS Code's backend is particularly interesting - it democratizes AI coding tools and removes the need to fork entire editors just to add AI capabilities. The format now includes more technical deep dives, meant to be reusable by others across teams. Instead of just tracking market trends, we're documenting what we're actually building and how others can use it. ![](assets/forward-engineering-05-2025.mp4) ## We're building a different kind of company The changes in May show we're not building a traditional consulting or product company. The shift from consulting-first to research-first is already changing how we allocate resources, approach hiring, and prioritize work. Our hiring strategy has started leaning toward specific traits: data intuition, architectural thinking, and a sense of aesthetic judgment. We're also preparing for an apprenticeship model to grow these capabilities internally over time. Knowledge capture through tools like MCP Playbook, Observer Log, and runbooks lays the foundation for smart scaling. When operational knowledge lives in systems instead of people's heads, growth multiplies instead of getting lost. On the infrastructure side, treasury protocols and automation systems are doing the heavy lifting. When admin runs itself, people can focus on problems that actually require human judgment. Read more: https://memo.d.foundation/build-log/company ![](assets/2025-whats-new-may-consulting.png) ## What's next in June June's looking interesting: expanding MCP server capabilities, finalizing vibe coding course materials, continuing to build tools that solve real problems. The apprenticeship program is taking shape, and we're seeing what AI-first consulting actually looks like in practice. The next phase is moving from AI workflows to AI agents - systems that can orchestrate multiple tools and handle complex planning autonomously. We're already seeing early patterns of what this looks like through our MCP ecosystem and vibe coding approaches.

A protocol for asynchronous shadowing

## Introduction: a standard for high-fidelity mentorship The goal of shadowing is to transfer skills effectively, not to fight with tools or slow procedures, or create a security situation like sharing GitHub credentials. To make this work, we're experimenting a protocol that prioritizes direct and efficient collaboration. We use a focused set of tools to create a fast feedback loop: **tailscale** provides a simple and secure peer-to-peer network, while **git** and the **aerc** email client enable a mail-driven workflow. This approach keeps the entire review process inside the terminal, close to where the actual engineering happens. This is a similar workflow you would see when **contributing to the Linux Kernel**. ### Workflow overview ```mermaid graph TD A["Shadow: Develop Code on Feature Branch"] --> B{"Shadow: Commits Ready?"}; B -- Yes --> C["Shadow: Generate Patches 'git format-patch main'"]; C --> D["Shadow: Send Patches via Email 'git send-email' or 'aerc'"]; D --> E["Mentor: Receive Patch Emails"]; E --> F{"Mentor: Review Patches"}; F -- Approved --> G["Mentor: Apply Patches 'git am 00*.patch'"]; G --> H["Mentor-Side Hook: 'post-applypatch' (Updates Commit Author)"]; H --> I["Code Integrated"]; B -- No --> A; F -- Changes Needed --> D; ``` ## 1. The network fabric: establishing read-only git access with tailscale The foundational layer of this protocol is a secure, zero-configuration peer-to-peer network. We use **tailscale** to create a private **tailnet**, placing the mentor's and the shadow's machines on the same virtual local area network. This allows the shadow to have read-only access to the mentor's git repository via the **git daemon**, eliminating complex firewall or public IP configurations. The mentor first shares their machine with the shadow via **tailscale node sharing**. Once connected, the mentor starts the git daemon in the repository directory they wish to share. ```bash # mentor: from within the project directory to be shared git daemon --verbose --export-all --base-path=. --reuseaddr ``` The shadow can then verify connectivity by pinging the mentor's **tailscale magicdns name** or ip address. ```bash # shadow: verify connection to mentor's machine ping ``` With the connection verified and the **git daemon** running on the mentor's machine, the shadow can clone the repository using the mentor's **tailscale magicdns name** (e.g., `mentor-machine-name`) and the repository's directory name (which is `.` in the `base-path`, so it refers to the directory name itself). ```bash # shadow: clone the repository # replace with the mentor's actual tailscale machine name # replace with the name of the directory the mentor is sharing git clone git:/// ``` This setup provides a simple, secure, and read-only channel for the shadow to access the codebase. The **node sharing** feature ensures the shadow only has network access to the mentor's designated machine. ## 2. The transport mechanism: asynchronous review with git and aerc This protocol utilizes the time-tested, email-based workflow originally developed for large-scale distributed projects like the Linux kernel. This method decouples the code submission and review process from a centralized platform, enabling true asynchronicity. The shadow serializes their git commits into a **patch series** using the **git format-patch** command. These patches are self-contained text files that represent a discrete unit of work. The patches are then transmitted via email, where they can be reviewed and applied by the mentor. While `git send-email` is the standard tool for dispatching patches, using a terminal-based email client like **aerc** is highly recommended for the mentor. For the mentor, **aerc** offers powerful features for viewing patches directly in the terminal and can simplify the process of piping email content directly to `git am`, further reducing context switching. However, the use of **aerc** is optional, and the core protocol functions effectively with any email client capable of handling plain text attachments or inline patches. The primary commands for this stage are as follows: ```bash # shadow: from within your feature branch, create patches for commits # that are not yet in the 'main' branch. git format-patch main # this will create one or more .patch files in your current directory, # for example: 0001-add-new-feature.patch ``` Once the patches are created, they are sent to the mentor for review. ```bash # shadow: use git's built-in email tool to send the patch series. # ensure your .gitconfig is set up for sending email. git send-email --to="mentor.email@example.com" 00*.patch ``` Otherwise, you can also specify the relative commit without creating a patch: ```bash git send-email HEAD~3 --to="mentor.email@example.com" ``` This command dispatches each patch as a properly formatted email, ready for inspection and application. ## 3. The end-to-end operational workflow The complete process provides a clear and efficient loop for submitting, reviewing, and integrating code. 1. **Network setup.** The mentor shares a **tailscale node** with the shadow. The shadow accepts. The mentor starts `git daemon` in the project directory. The shadow verifies the connection and clones the repository. This step is typically only performed once at the beginning of the shadowing period, with the `git daemon` being run by the mentor as needed. 2. **Task execution.** The shadow completes a task on a local feature branch, making one or more well-formed, atomic commits. 3. **Patch generation.** The shadow generates the patch files from their commits. ```bash # shadow: create patches from your current branch against the main branch. git format-patch main # output: # 0001-refactor-the-authentication-module.patch # 0002-add-unit-tests-for-new-auth-flow.patch ``` 4. **Patch submission.** The shadow sends the generated files using **git send-email** or an integrated client like **aerc**. ```bash # shadow: send all generated .patch files. git send-email --to="mentor.email@example.com" 00*.patch ``` 5. **Review and application.** The mentor receives the patches as emails. They can review the code directly in their client. If the changes are approved, they use **git am** (apply mail) to apply the patches directly to their local repository. This command applies the commits exactly as the shadow created them, preserving authorship and commit history with perfect fidelity. If using **aerc**, the mentor can often pipe the email directly to `git am` for even faster application. ```bash # mentor: apply all patches from the received emails (saved as .mbox or .eml files). # assuming the patches were saved to files, or piped from an email client like aerc. # Example with saved files: git am 00*.patch # Example with aerc (conceptual, actual command might vary based on aerc setup): # ` elements enhance their styling and customization capabilities.

Bài Minh Lê thì chắc lấy bài Minh Lê lên xem thử. **[08:53]** Lần này, bữa trước thấy anh em team bắt đầu viết, nhìn rất ok. Cuối cùng đăng hôm nay. Nên mình có hai, hoặc hai rưỡi topic cho mọi thứ. Thiếu mấy đứa rồi. Anh đâu rồi? Mấy nhóc kia đâu, biến hết rồi? **[09:34]** Lên nào, lên tổng kết tí. Em ơi, anh đâu rồi? Đây nè. Rồi, đủ mặt, đủ mấy nhóc vô xem. Ừ, Tuấn, Tuấn đi chơi về vui không? Mua gì không? Tuấn trốn trong văn phòng rồi đúng không? Vui quá ha. Nếu đổi lịch thì làm bài Minh Lê trước nha. Hai tuần trước. **[10:32]** Thấy mấy bài đã public rồi. Anh muốn nghe trực tiếp, xem chất lượng bài market report thế nào. Mọi người xem thử luôn, anh chen vô tí về thị trường. Tiếp theo là tổng kết, có vài chính sách muốn thông báo. **[10:54]** Sắp tới có update nhỏ, rồi sau đó tổng kết năm. Inno viết bài rồi. Ngồi đọc chung xem sao. Rồi tới bài cuối của Minh Lưu. Chắc làm luôn, bài trước cũng là Minh Lưu. **[11:22]** Bài trước của Minh Lưu nói về cái gì? Finite state machine trong Erlang đúng không? Hôm trước anh em còn nhớ gì không? Đánh giá sao, cho rating một phút. Còn nhớ nói gì không? Độ tập trung thế nào? **[11:57]** Bài tháng trước hả? Minh Lưu làm về finite state machine. Còn nhớ nó quan trọng sao không? Nếu nhớ thì sao dùng Erlang khi Elixir cũng làm được? Huy Nho có bài đó không? Huy Nho có tham gia không? Anh thấy bên nhóm của em có nhắc tới làm state machine khá nhiều. **[12:26]** Huy có góp mặt không vậy? Bên chỗ Minh Lưu là bên Yolo, tụi nó đang xài cái đó cho mấy dự án bên này, đúng không? Còn bên em thì ở Ascenda, cả hai chỗ đều có xài rồi. Làm cái framework, rồi làm cái controller, tới cả stage controller nữa, đúng không? Bên mình thì đang thử mấy cái đó, kiểu như là làm sao để tối ưu hóa được cái luồng xử lý state trong mấy dự án hiện tại. **[12:56]** Chuyển kiểu round-robin đúng không? Bên này thì define mấy cái state trước, rồi cái state nó sẽ set một cái context, kiểu như là enter state hay state hiện tại là gì, để bên ngoài chỉ cần switch qua lại giữa các state thôi. Còn bên Yolo thì em chưa biết rõ lắm, em chưa xem kỹ bài của Minh Lưu. **[13:19]** Chắc được ha? Ok, có mấy người mới nhảy vô luôn kìa, đông vui rồi đây. Vậy thì chắc cho Minh Lưu lên trước đi thôi. Minh Lưu chuẩn bị đi nha, Minh Lê ngồi đợi xíu. Lên nào, Minh Lưu, nhanh lên, nói một chút thôi cũng được, vì cái này cũng quan trọng, anh em cần hiểu rõ hơn về hướng đi này. **[13:41]** Em có 10 phút thôi, 10 phút là ổn. Bài này nối tiếp cái trước đó, tí nữa em sẽ nhắc lại tại sao cái này nó quan trọng với team mình. Em muốn anh em thấm cái này thật kỹ, vì đây là một kỹ thuật không dùng nhiều trong Erlang, nên nó khá đặc biệt. Mấy cái này bên mình làm xong thì có thể áp dụng qua mấy dự án khác nữa. **[14:12]** Order Minh Lưu nha, em có slide sẵn đây rồi. Để em review lại bài trước một chút cho anh em nhớ. Trong đó có cái behavior, tức là một pattern để mình define một cái module. Nó sẽ set sẵn một số hook, rồi mình dựa vào đó để xử lý các trường hợp cụ thể trong code, kiểu như là chuẩn bị trước một bộ khung cho mấy cái chức năng chính. **[14:49]** Mình sẽ implement mấy cái hook đó. Hai cái phổ biến nhất là gen_server và gen_statemachine. Đa số module thì viết dưới dạng server là được rồi, đặc biệt với mấy cái state machine đơn giản thì gen_server đủ sức đáp ứng. Nhưng mà tùy trường hợp thì mình mới chọn cái nào, không phải lúc nào cũng xài bừa được đâu. **[15:14]** Gen ở đây là viết tắt của generic, tức là generic server đó. Mình chỉ nên dùng gen_statemachine khi thật sự cần mấy tính năng nâng cao, ví dụ như insert event—tự chèn một event vào trong stage—or là cần trigger một cái action cụ thể khi switch giữa các stage. Cái này thì gen_server không làm được tốt bằng, nên phải cân nhắc kỹ. **[15:36]** Khi chuyển từ stage này sang stage khác mà mình muốn nó tự động chạy một action sẵn, thì cái đó gọi là state entry. Hoặc là mấy cái liên quan tới timeout, kiểu như set thời gian chờ giữa các bước. Trong thực tế gen_statemachine thường được dùng khi mình muốn implement một cái gì đó persistent, tức là cần giữ trạng thái lâu dài. **[15:59]** Ví dụ như TCP connection chẳng hạn, người ta hay dùng state machine để xử lý mấy cái này. Khi mình đã có một set các state cố định và cái connection đó cần persistent, thì lúc đó gen_statemachine là lựa chọn hợp lý nhất. Còn với mấy trường hợp bình thường khác thì gen_server là đủ rồi, không cần phức tạp quá. Hôm nay em sẽ code một ví dụ cụ thể để anh em hình dung rõ hơn. **[16:24]** Như anh Minh có hỏi bữa trước, tại sao phải dùng Erlang trong khi Elixir cũng làm được cái này? Thì đúng là vậy thật, behavior trong Erlang thì bên Elixir cũng gọi lên được và implement tương tự luôn. Nên hôm nay em quyết định làm ví dụ bằng Elixir để anh em dễ so sánh, xem cái nào tiện hơn trong trường hợp này. **[16:49]** Code bằng Elixir thì nhìn nó trực quan hơn một chút. Có slide không nhỉ? Slide về gen này đây, để em cho anh em xem thêm chi tiết, biết rõ hơn cách nó hoạt động. Ok, em chèn slide vô luôn. Hôm nay mình sẽ làm một module để connect TCP tới Redis server, giữ nó đơn giản thôi, chỉ có hai stage để dễ hiểu. **[17:34]** Hai cái stage thôi, tức là nó sẽ là một module nằm giữa user và Redis server. Module này sẽ implement phương thức để connect tới đó và làm trong suốt quá trình connect tới server. Ví dụ, khi process của mình bắt đầu một connection tới server thì tất cả request từ user tới nó sẽ trả về trạng thái disconnect hết. User không biết process thật sự mình gọi tới server ra sao, chỉ thấy qua process của mình thôi. Nên nó có hai stage: thứ nhất, khi khởi động process lên thì nó ở trạng thái disconnect. **[18:21]** Mình sẽ thiết lập một connection tới Redis server; sau khi connection thành công thì chuyển sang trạng thái connect. Còn nếu connection bị lỗi hay gặp vấn đề gì đó mà đứt, thì mình quay lại trạng thái disconnect và cố gắng restart lại connection. Những request, tức event request từ client, sẽ nhận dưới dạng event. Event có thể tới lúc disconnect hoặc connected; khi tới lúc disconnect thì mình chỉ đơn giản trả về cho client trạng thái là disconnect. **[18:41]** Connection thì những request, tức event request từ client, sẽ được nhận dưới dạng một event. Event này có thể tới lúc disconnect hoặc connected. Khi tới lúc disconnect thì mình chỉ đơn giản trả về cho client trạng thái disconnect. Còn nếu tới lúc connected thì mình gửi request đó lên Redis server, lấy data trả về cho client. Tại sao cần dùng state machine? Vì mình cần mấy tính năng như insert event mà em vừa nói. Đây, mọi người thấy không, để em zoom lên. **[19:39]** Trước tiên, mình implement behavior trên state machine, define cái data trong behavior này. Nó có hai thứ: State là stage thể hiện trạng thái của module, và Data chứa dữ liệu khi state chuyển đổi, mang theo một số data để xử lý trong module. Data gồm host, port để connect tới Redis DB, và request là map chứa danh sách ID của client cùng key là ID để biết trả về cho client nào. Khi start process này lên, việc đầu tiên là connect tới Redis server, chạy trong background và trả về trạng thái disconnect cho user. **[21:04]** Trước tiên, mình define callback mode gồm hai thứ: State function—tức đặt tên hàm trong module theo tên stage, ví dụ stage disconnect thì module tự chạy vào hàm disconnect để xử lý dựa trên tên và số tham số—và state enter, tí em giải thích sau. Bắt đầu bằng hàm init, mình trả về next_event, tức module tự insert event internal_connect với data là host, port để connect tới Redis server, rồi trả ngay trạng thái disconnect. Khi trả về disconnect, nó chạy vào hàm disconnect để xử lý. Hàm disconnect với internal_connect sẽ mở TCP socket bằng gen_tcp tới Redis server, bắt đầu thiết lập connection trong background. **[21:49] C**ái state enter thì tí em sẽ giải thích sau, ý nghĩa của state function là như vậy. Xong rồi mình bắt đầu bằng hàm init như hồi nãy em nói. Trong init thì làm gì? Đơn giản là khi bắt đầu hàm, mình dùng một term là next_event. Next_event là gì? Nó sẽ tự insert, tức module này tự chèn một event vào trong tay nó. Event này là internal_connect, dùng với data là host và port để connect tới Redis server, rồi trả về ngay lập tức trạng thái disconnect. **[22:43]** Khi trả về trạng thái disconnect như vậy thì việc đầu tiên là nó chạy vào hàm disconnect để xử lý. Hàm disconnect với internal_connect này làm gì? Thứ nhất, nó mở một TCP socket bằng gen_tcp tới Redis server. Rồi mình chợt thấy hơi nhiều chi tiết quá, em gộp mấy hàm lại thử được không anh em? Anh chen vô cho anh coi mấy chỗ define hai cái stage của nó, coi hơi rối quá rồi. Chỗ nào define hai trạng thái đâu đây? Mọi người thấy đó, nó có cái list ở kia, mình có hai trạng thái thôi ha. **[23:48]** Ở đây là hai trạng thái, bốn cái overlap function của disconnect và connect. Minh có bốn overload của connect, còn hai trạng thái thì bình thường thôi. Bên Elixir thì nó overload dựa trên param list đưa vào, nó biết chạy cái nào. Chỗ thứ hai là chỗ nào chuyển trạng thái đâu? Ờ, nó nằm trong từng hàm. **[24:42]** Ví dụ hàm connect này, khi connect thành công thì nó trả về một atom next_stage, chuyển trạng thái sang connect ngay đây, cùng với data đó. Hiểu rồi, đây là chỗ gọi để chuyển từ state này sang state kia. Nhưng mà với mỗi overload function vậy, em gọi implicit thế này thì có đúng không ta? Thường mấy cái này sẽ có dạng controller để quản lý, chứ gọi chi tiết kiểu này nhìn hơi rối. Có 10 stage trong đây mà define xong gọi thì quản lý khùng luôn. **[25:01]** Cái ngay chỗ này nè, ngay backend của mình á. Vì state function thì mình có một cái gọi là handle_event function. Khi chuyển sang xài mode như thế này, mình chỉ cần define một function là handle_event thôi. Ví dụ vậy thôi, mình chỉ cần define xong là quản lý hết tất cả state trong cái function đó. Nếu muốn kiểu cách như vậy, nó cho mình lựa chọn giữa việc define function theo state hoặc define một handle_event function. **[26:14]** Giờ kêu hình đâu, Bảo Hân Trần có nhìn vô cái này, có xài cái này bao giờ chưa? Để trực quan thì em có copy một cái thư viện connection, cũng tới TCP đây. Nó viết bằng gen_server, không xài state machine, theo kiểu button như vậy. Connect fail thì nó back off, rồi retry, cũng quản lý user trong một cái map. Nhưng nó hơi dài hơn tí, phải implement lại mấy thứ có sẵn ở bên này, như timeout chẳng hạn, nó phải tự implement lại hết. Rồi câu hỏi là chị hỏi em cũng mới học, mới làm cái này. Mình biết cái này lâu rồi đúng không, nhưng lúc tiếp cận thì thấy sao? Tại sao nó quan trọng? Nó define một số cách giúp mình làm tiện hơn, anh. Ví dụ như xử lý timeout, nó define dựa trên data mình trả về. **[27:47]** Ví dụ thế này đây. Khi connection của mình bị drop, mình chạy vô hàm disconnect để xử lý, nó cho mình trả về một atom timeout cộng với thời gian. Sau khoảng thời gian đó, nó tự động chạy vô đây xử lý cho mình. Ừ, đây, nó giúp mình làm mấy cái đó tiện hơn. Thay vì viết bằng gen_server cũng được, nhưng sẽ dài hơn. Ok, ok, cảm ơn Minh. Minh Trần có hỏi gì không? Ai nữa? **[29:14]** Nhờ Minh Trần code cái này nào, code Elixir nữa, nhờ anh biết có đụng tới đây chưa. Rồi đặt câu hỏi nha, phổ biến nhanh cho anh em: cái này nó như vậy, sự khác biệt cơ bản trong lập trình của nhóm mình, trong tất cả các ngôn ngữ lập trình hiện đại hiện tại thì không có ngôn ngữ nào có sẵn thư viện để quản lý state machine như con Erlang. Erlang là con duy nhất sinh ra để chạy mấy cái hệ máy tự động không xuất phát từ góc nhìn làm server đứng đó đợi gọi tới gọi lui theo mô hình client-server từ đầu. **[29:30]** Con này sẵn đúng không? Với cái vụ mà nó build-in trong đây thì lúc em lập trình, nó ra được hai thứ. Thứ nhất là nó ép cả đội học ngôn ngữ này, có tooling này sẽ hình thành một mental model, một mô hình tư duy giống nhau. Gặp đúng trường hợp thì mình moi cái tool ra xài, suy nghĩ giải bài toán theo cách này. **[30:07]** Lúc làm mấy cái model như C4 á, hồi đó cũng đụng tới đây thôi đúng không? Nó cung cấp cái tool cho mình. Thứ hai là nó unify tư duy lại với nhau. Tất nhiên gen_server thì vẫn code kiểu bình thường, anh em xài vẫn ok, không sao hết. Nhưng điểm đặc biệt của Erlang là có cái này. **[31:13]** Khi team thấm rồi, quản lý code base dưới dạng state machine, chuyển state vòng vòng mấy cái object, thì nó giúp quản lý source tốt hơn. Tránh việc code implicit, đẩy code đi vòng vòng, hồi không biết mình chuyển qua đâu. Mình tập trung vào logic, vào góc nhìn nhiều hơn là lo cái data bên dưới nó thế nào. Chứ không thì lỗi xảy ra rất nhiều trong code base lớn, không nhìn theo kiểu này là lỗi đầy ra, phải đứng ra làm lại hết. Đó là lý do con này đặc biệt, với Erlang thì đặc biệt vậy thôi. Về Elixir, mấy cái thằng kia không build thư viện này lên, nên xài vẫn phải chọt trực tiếp trên Erlang. **[32:08]** Ừ, thôi đó là tóm tắt nhanh bài của Minh Lưu. Nếu Minh Lưu làm bài tiếp theo, anh đề nghị làm cái gì phức tạp hơn xíu, thực tế hơn xíu. Bài kia có hai stage nhìn còn đơn giản. Hoặc kiếm mấy cái clip open source của tụi nó, quản lý state nhiều hơn. Có cái ví dụ của một nhóm nào đó, xài quản lý mấy WebSocket, nhiều stage lắm. Chỗ đó cũng có xài một phần gen_statemachine, một file lên tới ngàn dòng. Lúc gộp hàm lại thì thấy cấu trúc rõ ràng, không phải kiểu implement đẩy qua đẩy lại lung tung, có một con manager đứng quản lý. Anh em lâu lâu mất não quay lại nhìn vẫn dễ chịu hơn là nhìn mấy hàm tự đặt tên, nhìn mệt lắm. **[34:18]** Cái chuyện hình thành mental model chung của một nhóm cực kỳ quan trọng. Cảm ơn Minh Lưu, mời Minh Lê. Dạ, để em coi em có bao nhiêu phút? 10 phút không? Ừ, 10 phút, tại em đang có bốn bài rồi hả? Lúc trước bên team consulting có ra ý tưởng viết series hàng tuần, mỗi tuần một bài tổng hợp thông tin liên quan tới bên test mình. Nhưng nó không sâu về test quá, chỉ chung chung. Bài đầu tiên em viết từ giữa tháng 12 năm ngoái, cover lại chuyện đợt Google ra Gemini 2.0, rồi Open AI ra model chain video. **[34:38]** Mấy cái hình ảnh của nó cho người bệnh, hoặc mấy người khỏe mạnh đeo vào, như mấy cái đồng hồ anh em mình đeo để theo dõi nhịp tim ấy. Rồi bên consumer tập trung vào mấy cái bí mật, như mấy cái để render ra video giống con Sora. Ở trên crypto thì nó cũng gắn AI vào fintech, gaming, infrastructure này nọ. **[35:21]** Bên Y Combinator cũng tương tự, họ kêu gắn AI vào mọi chủ đề hiện tại. Họ đang tập trung bảo mọi người nghiên cứu stablecoin. Lúc trước thì kêu làm Bitcoin với Ethereum để thanh toán, nhưng sau một thời gian thử nghiệm trên thị trường, họ thấy mấy cái đó không hợp lý. Nên giờ họ chuyển qua nghiên cứu hướng stablecoin, kiểu đủ thị phần để mấy công ty bỏ tiền nghiên cứu, rồi build giải pháp thanh toán. **[36:21]** Ở đây em nói sơ về một product, một cái AI agent platform trên Solana. Họ khẳng định đây là nền tảng cho mình tạo mấy con AI agent. Mấy con AI agent này giúp quản lý ví, tạo coin, tự trade, nói chung là tự động hóa mấy thứ mà dân crypto với DeFi hay làm. Product này giúp người ta làm vậy dễ hơn với sự hỗ trợ của AI. Đó là bài thứ nhất, qua bài thứ hai. Bài thứ hai trong bốn bài, nhiều lắm. Giờ câu hỏi chính là qua bốn bài tháng vừa rồi, em nghĩ cái gì benefit team mình? **[37:13]** Ừ, em nghĩ chắc mình đang đi đúng hướng, tập trung vào mấy công nghệ AI, làm quen với agent, blockchain này nọ. Nó đang phát triển rất mạnh, đang bùng nổ thị trường, rất hot. Sắp tới chắc cũng có nhiều product tập trung vào đó. Còn mấy mảng như Y Combinator hay a16z đề xuất thì hơi vượt xa tầm với của thị trường mình, nên cũng khó nhảy vào. Nhưng tuần vừa rồi em coi một cái thống kê sơ về nguồn tiền chảy ra chảy vào ở Đông Nam Á, quý cuối 2024 vừa rồi, thì đây là top mấy ngành đang được đổ tiền vào nhiều. **[38:23]** Ngành thứ nhất là challenger banks. Nó khác ngân hàng truyền thống, tập trung hoàn toàn vào ngân hàng số. Ở Việt Nam mình hình như có một cái ngân hàng số, nhưng không được định nghĩa là challenger bank hoàn toàn. Như mấy thằng Timo này nọ, nó được gọi là neobank nhiều hơn. Challenger bank là kiểu có giấy phép hoạt động như ngân hàng thật, tự đưa ra sản phẩm mới trong ngân hàng số của nó. **[40:08]** Còn neobank ở Việt Nam thường có ngân hàng truyền thống đứng sau, bật giấy phép, không tự phát hành sản phẩm ngân hàng được. Ở Đông Nam Á, mấy VC đang đầu tư mạnh vào challenger banks, vì họ nghĩ nó giải quyết vấn đề tiếp cận tài chính cho mấy vùng không có điều kiện, hơn là crypto. **[40:30]** Nghe nói em có kiểm tra lương bổng, mấy con số lương phải trả cho ngành IT ở các nước Đông Nam Á. Bên Philippines đang có giá cả khá cạnh tranh, dân số thì đông, giáo dục cũng đang phát triển ổn. Ngành nhân lực IT của họ đông lắm, làm cho mấy công ty nước ngoài, tiếng Anh thì rất tốt, mà giá lại cạnh tranh hơn so với mấy nước Đông Nam Á như Việt Nam mình. **[41:26]** Việt Nam mình vừa rồi quý 4 bị giảm đầu tư khá nhiều, tới hơn 80% luôn, còn Philippines thì tăng mạnh, phát triển lắm. Họ đang đẩy mạnh thương mại điện tử, mấy cái digital, giống kiểu mình cách đây 3-4 năm trước. Giờ họ được đầu tư nhiều. Ok, interesting, kéo lên trên tí. Vậy mấy phần trên anh thấy toàn liên quan tới tiền, đúng không? Banking, ngoại tệ, rồi finance, toàn dính tới tài chính. Đông Nam Á chắc đang đầu tư mạnh vào mấy ngành này. **[42:39]** Nếu vậy, tuần tới mấy bữa nữa ngồi xem tiếp, soát thử danh sách tiềm năng, coi mấy cái ecosystem map hay system hiện tại của tụi nó, tìm được không? Dạ, để em kiếm thử, mấy report thường có mấy cái đó. Ừ, ok. Còn gì nữa ngoài cái này không? Thấy tuần này là tuần Giáng sinh, ít tin tức, cũng chán. Em có để mấy product blockchain mới, đang được người ta đổ tiền vào nhiều, lock vốn nhiều. Blockchain hả? Cho anh xem thử coi. Liquid rồi, ok, phút phút, tụi nó share trong kênh chat rồi, ok lắm. **[44:19]** Nếu vậy có hướng này. Thật ra để viết bài này, anh thấy có góc nhìn thế này. Nếu được, mấy anh em ngồi xem, em có thể trả lời theo góc nhìn: slogan của team mình từ đầu là “empower innovation”. Tức là mình tìm mấy cái innovation đang xảy ra, để có cơ hội làm chung với tụi nó, hoặc hỗ trợ, thậm chí invest luôn thì quá đẹp. Cái interest lớn nhất khi anh em làm cái này là tìm xem innovation đang ở đâu. Thay vì điểm tin chung chung, em có thể chỉ rõ mấy điểm nhịp của market, chỗ này chỗ kia, innovation sẽ diễn ra ở đó. Trong đó, business model hay financial model là gì, trả lời đúng trọng tâm của mình, cũng là kiến thức dễ ping bài toán kinh doanh. **[47:25]** Coi thử hướng đó nha. Ok, cảm ơn Minh nhiều. Trước giờ mình thiếu cái đó, kiến thức trôi nổi, không tập trung. Góc nhìn này sẽ giúp team hiểu rõ, khi soát dự án cứ nhìn kiểu: chỗ nào sale, chỗ nào có tiền. Cách nói khác là innovation đang ở đâu, mọi người làm gì mới ở đó. Ngành software của mình, chỗ nào đang build mới thì mình mới có cơ hội nhảy vào review. Còn mấy cái bùng nổ quá thì chỉ làm retainer, dán dự án, chán lắm. Ok, chắc hết phần này. Giờ tổng kết năm nhanh xíu. Mấy anh em ra ngoài offline là xong. Câu hỏi nhanh: Huy với Thành chuẩn bị mấy phần rồi, out hết chưa? Chắc hết rồi. **[47:50]** Năm nay thị trường thay đổi nhiều quá, mấy cái assumption trước đây nó thay đổi hết, cũng không biết đâu mà lần. Nhân sự mình cũng có sự chuyển dịch tương đối, đúng không? **[48:53]** Nhiều thứ định hướng của mình cũng shift đi, từ mô hình cũ tập trung vào enterprise, nhưng AI ra đời thì wipe hết thị trường luôn, đủ trò hết. Định hướng sắp tới mấy em nhìn chung thấy thị trường đang chuyển dịch theo hướng tiếp cận tài chính, blockchain. Nói chung AI đang hot, nhưng tính ứng dụng vào doanh nghiệp chưa nhiều lắm, đang bùng, mọi người thi nhau bùng thôi. Còn hướng chính vẫn là đánh về tài chính. **[49:55]** Hướng đó thì vô tình Engineering của mình đi research cái đó, học cái đó, đang diễn ra nhiều. Nên Year-end hiện nay công bố luôn nhờ, có bao nhiêu giải? Năm nay team có bốn giải, còn một giải trong phần community. Vẫn có một giải cao nhất thuộc dạng kiểu vầy cơ. Còn mấy giải kia thì dạng honorable mention. Tất cả giải thưởng này rút ra là để vinh danh mấy bạn high performer trong năm vừa rồi qua các mảng chính của team mình. Chắc để công bố luôn, bảy giải từ bốn giải là gì? **[51:05]** Một giải đội hả? Ba giải còn lại gì? Giải thứ nhất cho bạn execute cái model AMA của mình tốt nhất vừa rồi. Giải thứ hai thuộc về giải thí sinh cho team lead, bạn nào dẫn dắt team mình ok nhất, được number one. Giải thứ ba thì cho bạn perform tốt nhất ở bên phần consulting. Project có hai performance được anh em trong team đánh giá cao và khách hàng đánh giá cao vừa rồi. Giải thứ ba thì cho tập thể team nào đó perform cộng, có hai đầu: một là perform để ghép được phần inhousing, hai là nâng cao độ tin nhiệm và upsell thêm cho team đó. **[53:38]** Giải cuối thì cho community, mấy bạn supporter không thuộc official team nhưng có setting với mình, tham gia hoạt động, sharing cá nhân. Ok, vậy là bốn cái đúng không? Developer of the Year tức là mô hình MMA: meaning, mastery, autonomy. Giải thứ hai dành cho hướng style research, là giải động team lead. Giải thứ ba là consulting, ba giải cá nhân và một giải đồng đội là dự án thấy có impact nhất. Mấy dự án khác không impact bằng thì không tính sau nhé. Cuối cùng là giải community, mà community ở đây đâu có ai đâu nhờ? Năm vừa rồi thấy ít mà, phải không? Ừ, thật ra là có bạn làm việc với team mình khoảng mấy tháng thôi. **[54:26]** Rồi, chắc làm cái công bố nhanh thôi, mấy anh em in-out cái đó cho dễ, ok không? Chứ anh làm cho chuẩn thì lâu lắm, rồi tính tiếp. Cho xin cái reaction cái nào, zalo hay slack để mình capture lại nhờ. Hai con VIP kêu rồi, ok. Rồi, good. Giải thứ hai nhờ Thành công bố cái gì hay giải gì nhờ, cần soát tin rồi check, ok. **[55:58]** Cho phút lead xin cái reaction. Ủa, còn setting này là cá nhân hả? Đúng rồi. Ok, có thể điểm sơ qua được không? Trước giờ performance mình thấy cũng như mấy năm trước thôi, không biết cụ thể sao, mời. Ừ, vừa rồi thì chắc tí nữa Huy sẽ cho comment chi tiết hơn. Nhưng đánh giá tổng quan mà Thành xem được của Phúc vừa rồi thì thực ra trước giờ, mấy năm trước Phúc đa phần làm internal project với consulting, chủ yếu đợt này qua làm bên team Yolo. **[57:21]** Thực ra với role nó hơi yếu đúng không, so với expectation dạng depth của backend các thứ. Trước đó role của Phúc focus chủ yếu liên quan đến iOS thôi. Ban đầu thì ông này bên đó cũng skeptical về Phúc, nhưng thấy bảo adapt rất ok. Trong đâu đó năm sáu tháng, anh em bên đó chắc đánh giá ưng nhất, mà nghe nói cũng khó tính. Chi tiết thì chắc Huy có comment chính xác hơn, vì trong project của mình thì Huy chọn mà. Mắt em comment là sao, anh này comment về em mà. Thật ra em nghĩ mấy bạn làm thì cũng tương đối nhiều, mặt kháng giá, lập này nọ. **[58:46]** Nhưng em nghĩ chỗ anh Thành chọn Phúc là vì thấy sự vừa expectation của mọi người tí. Lúc trước Phúc cũng có làm dự án, nhưng khá im, không giao tiếp vào xong thôi. Dù tài năng rất tốt, nhưng trong năm nay thì có nhiều cái vượt xa mức đó. Ví dụ thành quả là mấy cái style khác, loop rồi, đi mấy cái style JavaScript, TypeScript các thứ, dù lúc trước không liên quan lắm. Rồi còn liên quan đến việc bắt đầu có mấy cái cần soát với khách hàng, deadline kiểu này không ổn. Đỉnh nhất là vừa rồi, chỗ bảo muốn làm cái này, nhưng Phúc bảo không kịp đâu, từ từ làm. Đó là dấu hiệu ban đầu, rồi cũng bắt đầu có việc trọn Phúc cho mấy cái phát triển vừa bực hơn, ghê hơn, chứ không hẳn là nhất. Nhưng expectation của Phúc có vẻ tốt nhất. Ok, đúng là Superman ha. Phúc có lên phát biểu không? **[61:03]** Chế độ này ngồi sao được, em gắn headphone vô. Em cũng thấy hơi bất ngờ, tự nhiên được cái này. Đang bắt xe xuống cái từ thiện, em cũng không biết nói gì, mà thấy có nhiều hết nghe rồi. Ô, Ngọc Thành vô nè, lâu mới gặp Ngọc Thành, nghe Phúc ơi. Thức nó sao giờ, nó mute luôn rồi. Ở ngoài đường thì hiểu cảm nghĩ là giải thứ hai, em nghĩ cái này có xứng đáng không, thấy hơi ngại, chào đúng không, khó quá. Đủ để anh nhận hội. Dạ, đúng rồi. Giải tiếp theo nhờ Huy, xin mời cho team, thì vô cho bên key team của bên Yolo. Ok, team Yolo tức là như nào? **[62:28]** Là Yolo đang nghĩ nó là một cái tiêu biểu nhá. Ừ, đồng ý. Giải cuối cùng rồi, còn lại thì trao bạn này. Cho ai cũng cần đạt thì cũng có khoảng thời gian đâu đó 2-3 tháng làm intern với mình, chủ yếu là em research liên quan đến mấy thứ liên quan đến phần mềm. **[63:20]** Thực ra trước đó, Đạt cũng có trước khi join mình làm intern thì cũng tương đối active trên server mình rồi. Kể cả sau khi kết thúc intern, vẫn tiếp tục với mấy cái về build trên AI. Những bài share thì được mấy anh em phía core fork, hướng lại tương đối nhiều. Một tiêu biểu mà bên cộng đồng mình đang muốn khai thác, và Đạt chắc nên phát biểu tí. Đạt ơi, team có dành phần quà community dành cho em, giờ đang thế nào, đang ở đâu rồi? **[64:26]** Em đang ngoài đường, chưa tới giờ hết đi họp hết trơn rồi à? Em cảm ơn mọi người đã dành thời gian cho em. Phần lớn thì anh Tom với anh Thành giúp em rất nhiều trong câu chuyện onboarding với cả share lại cho team sao cho ok, kiểu có thể delivery được kiến thức cho mọi người. Còn gì nữa không? Dạ, chắc không, em nghĩ như vậy. Cảm ơn Đạt đã dành thời gian ha. **[65:11]** Ở style với mấy anh em, việc mình đọc cái gì hay thì chia sẻ cho mọi người, rất là appreciate mấy phần của Đạt. Even là hiện tại, mấy anh em thấy trong hoạt động chia sẻ kiến thức trong team, cái đó là cái chính. Tại hướng đi innovation nó cứ thay đổi suốt, mình kiếm được người đồng điệu, cơ hội làm việc trực tiếp thì chưa đến. Nhưng về cái chung, thấy những thứ thú vị, mình ngồi chia sẻ với nhau, đó là cái rất đáng quý ha. Cảm ơn Đạt. Chắc tới giải cuối cùng, Thành ơi, rồi sau đó mình kết thúc. **[66:14]** Giải Developer of the Year dành cho bé Biên đây. Anh em có in-out giùm cái. Biên ơi, bên đâu rồi? Xin cho biết lý do đề cử là như nào, xin mời. Từ từ anh em, ừ, rồi. Năm ngoái, năm trước nữa thì anh em đều biết, mọi người đâu đó mình có post một bài viết muốn execute theo model là AMA, viết tắt của mastery, autonomy, với cả meaning. Những cái để giải đáp thì thấy chủ yếu quan sát là bạn nào trong team execute được model đấy tốt nhất trong khoảng 1 năm trở lại. **[68:23]** Cái gì đấy, một cái mà team đang muốn triển khai trong giai đoạn mà AI có thể giúp mình làm phần unit work, rồi solution với design system các thứ. Vừa rồi nó quan trọng hơn đấy. Biên là một trong những anh em ở đâu đó mà đang nghĩ là execute mấy cái gọi là ninh với core goal của team rõ ràng nhất. Mọi người rất ưng khi làm việc với Biên vừa rồi, thì đó là mấy cái chính. **[69:18]** Mời Biên cho vài lời, xong rồi mình qua phần cuối cùng nhờ. Em ơi, theo comment của anh Thành thấy sao? Cảm ơn mọi người ơi, nếu có thay đổi gì thì cũng không sao rồi. Kết thúc ở đây nhé, phần của Biên dậy xong nhé. **[70:21]** Giờ tí nữa trước khi mấy anh em họp mình ra quán hết năm với nhau, thì có vài cái mới để định hướng lại sau Tết. Buổi này là buổi gặp tuần như cuối rồi nha, tuần sau đâu có gặp đâu, đúng không? Tại mình giảm thời lượng xuống còn hai tuần một lần. Mấy cái topic đang share với nhau từ cái idea đầu là mình fit mấy cái keyword để ngồi coi tiếp, học tiếp, tìm hiểu những cái mới để phát triển bản thân. Hiện tại mình giảm thời lượng họp xuống còn hai tuần một buổi, thì buổi cuối tháng 1 rồi, chặp sau Tết mới bắt đầu có buổi khác ha. **[71:49]** Hiện tại sau Tết, định hướng của team mình, mấy cái dự án mà tụi anh, phần Minh Lê á, nó vơi ra về chuyện innovation diễn ra ở những lĩnh vực như vậy. Bản thân mấy anh em trong team management cũng thấy cái đó, thật ra dự án như vậy đang dần về, mình đang build, làm hết trơn rồi. Cả những sản phẩm cũng theo hướng đó. Như vậy là sau Tết có một pha rất thú vị về chuyện làm startup, rồi build public cái trend mà sau khi nhiều engineer bị layoff. Có cái là mấy bạn đó chuyển qua tự build cho bản thân, tự kinh doanh, tham gia hội build public á, lo một cái token hoặc triển khai một quan alpha. Tự nhiên anh thấy cái flow ra, chuyện bốn thứ đó có điểm chung rất thú vị, vô tình hướng team đi theo hướng mà anh nghĩ từ đây đến giữa năm sẽ đẩy nhiều hơn, trên vực tài chính in general. **[73:07]** Nếu add cái framework đó vô thì gần như nó là một button repeatable, mình vừa có thể làm consulting trên đó, vừa apply hết kiến thức engineering vốn trước giờ khi làm mấy sản phẩm bình thường. Sản phẩm trước giờ chỉ làm trên dataset là list hay array thôi, giờ mình sẽ làm nhiều thứ khác, giải bài toán scale lớn hơn, làm application nhiều hơn được ha. Nếu muốn tự detect, tự lo cái trend của mình cho thị trường đầu cuối thì vẫn được luôn. Cái hướng rất thú vị, chắc để sau Tết, mấy buổi họp kế tiếp sẽ bắt đầu tiết lộ cho anh em. Với định hướng đó thì kỳ vọng mọi người cũng theo đó, thường định hướng của team sẽ quyết định tới nhân sự rất nhiều. **[74:28]** Nửa là sẽ đổi chính cho đầu năm sau. Với suy nghĩ như vậy, hiện nay anh muốn tạm thời quên đi cái chuyện team mình là team làm việc remote default nữa. Tức là không còn default là vô thì sẽ bị remote với nhau. Anh mong muốn sau mấy buổi qua, team mình sẽ setup lại sao cho mình sẽ sắp xếp lại cái loop của mình tí, với mấy dự án hiện nay đang hơi chểnh mảng, chưa biết giải quyết thế nào. **[75:15]** Toàn bộ dự án hơi cảm giác nhẹ nhàng á, anh đang gắn cái mác đó là retainer rồi check, cứ vô trỏng ngồi bình thường bình thường. Thì muốn có một cái policy công bố với anh em: từ sau Tết, mọi người sẽ phải đảm bảo lên văn phòng, với các bạn đang ở Sài Gòn nhé. Ở Hub Sài Gòn, mình sẽ không còn set cái chuyện làm việc remote default nữa, mà sẽ làm việc theo hub được ha. **[76:07]** Hai cái hub official đang có, even là ba cái: Sài Gòn, Đà Nẵng, Hà Nội, thì sẽ phải kiếm chỗ ngồi lại với nhau, resume lại physical connection. Anh em sẽ phải commit 3 ngày một tuần. Hub Long An thì sao? Hub Chân Giang mấy đó thua mấy đó thua mấy nơi. Trong giai đoạn vừa rồi, cảm giác khi mọi người làm remote thì có cái alone zone rất ok. Alone zone sẽ work khi kiến thức đã sẵn, không thay đổi. **[77:05]** Nhưng khi thị trường thay đổi thì mức độ trao đổi thông tin với nhau, nơi nào diễn ra càng nhiều thì nhân sự ở đó sẽ dễ thích nghi và phát triển hơn. Vì vậy, mấy anh em đang làm remote có khả năng rất cao là sẽ bị tụt lại, chưa biết sao. Có tuyển lại đó, anh sẽ post lại requirement sau cho chỗ Tân Nhật hả, Tân Nhật đúng không? Sẽ sắp xếp lại. Mấy anh em giai đoạn vừa rồi làm remote, khi thị trường không thay đổi về kiến thức thì có alone zone để tập trung làm việc rất thoải mái. Nhưng khi thị trường đổi tí, nơi nào thông tin diễn ra nhiều hơn thì anh em sẽ phát triển dễ thích nghi hơn. **[77:43]** Đó là lý do tại sao nó diễn ra như hiện tại. Hoặc mọi người phải cực kỳ active trên online, hoặc phải gặp nhau offline, đó là cái buộc ha. Với policy đó, anh em sẽ có 1 tháng để xem thử thứ của mình như nào. Với cái đà thị trường chuyển dịch, event là Meta mới layoff, mới bị magaling, không update thêm đống người, 50% của đó, 3600 người, bỏ hết. Tất cả doanh nghiệp đều rất skeptical về chuyện phát triển cái gì mới, nên cơ hội làm remote hoàn toàn đang hạn chế dần. **[78:35]** Đang không request mấy anh em thay đổi liền, nhưng anh đang có kế tiếp trước về chuyện như vậy. Trước nhất, anh em đang ở Hà Nội và Sài Gòn sẽ phải đảm bảo ngồi với nhau. Anh sẽ cố gắng sắp xếp team theo khu vực để mọi người resume lại cái của mình ha. **[79:29]** Đó là 3 ngày/tuần. Trước mắt giữa mấy anh em với nhau thì chỗ anh Thành sẽ… Anh Thành từ khoảng giữa năm thôi, không, anh Thành sẽ relocate lại về Sài Gòn là một. Huy Nguyễn thì đang run cái office ở Sài Gòn rồi. Mấy bạn hay lên office Sài Gòn không vấn đề gì lắm. Hiện tại sẽ test trước với cái đó, nó là policy chính thức luôn sau Tết nhé. Với mấy bạn mà tụi anh biết là đang ở Sài Gòn thì sẽ require cái đó ha. **[80:14]** Đó là thay đổi chính nhất trong vận hành. Chuyện thứ hai có thay đổi nữa là năm nay sẽ không có ref sharing. Những năm trước thì mình có chương trình ref sharing, năm nay chỉ có lương tháng 13 thôi. Cách đây khoảng tiếng rưỡi là anh đã gửi lệnh đi rồi, giờ mấy anh em đã nhận được lương tháng 13 của mình rồi. Nó là trung bình lương 12 tháng thôi, bạn nào vô trước thì theo tháng, đủ là đủ. Còn sharing năm nay thì không có. **[81:26]** Một chương trình khác, sharing là khi doanh thu giữ mức cũ hoặc cao hơn, thì thường anh sẽ chích ra bao nhiêu phần trăm trong doanh thu để chia lại theo mức seniority của bạn trong team. 8 năm thì khác, 5 năm thì số khác, mà năm nay sẽ không có cái đó ha. Toàn bộ điểm tin nhanh cơ bản của team sẽ có những thay đổi đó. Nếu anh em quan tâm hơn thì chỗ Inno có gửi một bài lên trên kia rồi. Mấy nay đọc hết chưa nhờ? Đây, mọi người nhìn màn hình nhé. Có bài điểm qua, anh thấy việc team vận hành hiện nay đang rất tốt, mọi thứ đã vào rượt với nhau hết rồi. **[82:41]** Bây giờ chỉ có lựa chọn thị trường nào, cơ hội nào để có biến động lớn, đột biến về thu nhập thôi, đó là cái chính. Còn với mô hình, cách vận hành hiện tại thì anh nghĩ rất happy với những gì đang diễn ra nhé. Nếu không còn gì khác thì chúc anh em tối nay ăn tối nhẹ nhàng, tình cảm với nhau ở hai địa chỉ. Hẹn gặp lại sau Tết với kế hoạch chi tiết hơn, recruitment mới hơn, cũng như mở ra lĩnh vực mới về tài chính. Anh nghĩ cơ hội đột biến tài chính cũng sẽ nhiều đó ha. --- ### English transcript **[01:29]** Alright, folks. It’s been a while since we were on stage. According to Thành’s plan, there are four presentations today as usual. I heard Phát mention four, just like every other time. But since there’s going to be a recap later, I think Thành wants to squeeze in one more. **[07:48]** Let’s shift the schedule a bit, Thành. Originally, the other team was going to continue the Engineering series the one the artisan group had prepared and presented. But I think for now, we’ll postpone that. Maybe next week or after Tết. **[08:09]** We’ll bundle it into a combo session and gradually introduce it to everyone, especially after that two-month stretch. As for the expanded topics and what’s next, we’ll save that for later. Let’s move to Biên’s part this is the second part of Minh Lưu’s talk on Erlang. He already did one last time, and now we want to review and get everyone’s thoughts. **[08:32]** What did you think of the last session? Do you still remember it? This time the vote is kind of split. I guess we’ll bring up Minh Lê’s talk to check it out. **[08:53]** Last time, I saw a few folks in the team starting to write things up it looked pretty solid. In the end, it got published today. So we’ll probably have two, maybe two and a half topics in total for everything. A few people are still missing. Where’s Anh? Where are the others? Everyone’s disappeared? **[09:34]** Alright, come on up. Let’s do a quick recap. Hey, where’s Anh? There he is. Okay, looks like we’ve got everyone. Let’s get the others in too. Tuấn, you back from your trip? Did you buy anything? You’re hiding in the office, right? Must’ve had fun. If we’re changing the schedule, then let’s start with Minh Lê’s session first. That was two weeks ago. **[10:32]** I saw a few posts already went live. I’d like to hear it directly and get a sense of the market report quality. Let’s let everyone see it too. I’ll also chime in a bit with the market section. After that, we’ll do the wrap-up. There are a few policy updates I want to announce. **[10:54]** There’s going to be a small update coming up. Then we’ll do a year-end wrap-up. Inno already wrote a post for that. Let’s read it together and see how it looks. After that, we’ll get to the final presentation by Minh Lưu. I think it’s the same one Minh Lưu did last time. **[11:22]** What was Minh Lưu’s last session about again? Wasn’t it about finite state machines in Erlang? Do you still remember anything from that? How would you rate it, just a quick take, like in one minute. Do you remember what it covered? How focused it was? **[11:57]** That was last month, right? Minh Lưu did a talk on finite state machines. Do you remember how important that was? If so, why use Erlang for it when Elixir can do the same thing? Did Huy Nho work on that one? Did he join the session? I remember your team mentioning a lot about building state machines. **[12:26]** Was Huy involved? Minh Lưu’s team Yolo is using that stuff in their projects, right? And on your side, at Ascenda, I think both teams have already adopted it. They’re building a framework, then the controller, and even a stage controller, right? On our side, we’re also experimenting with those ideas trying to figure out how to optimize state processing flow in our current projects. **[12:56]** Like using round-robin mode, right? On this side, we define the states first. Then each state sets a context, like whether it’s entering a state or which state it currently is, so the outside logic just switches between them. As for the Yolo side, I’m not too sure, I haven’t read Minh Lưu’s write-up in detail yet. **[13:19]** That should be good, right? A few more folks just jumped in nice. Okay, let’s have Minh Lưu go first. Minh Lê, hang tight for a bit. Come on up, Minh Lưu. Just share a bit, it’s important. The team needs to understand this direction better. **[13:41]** You’ve got 10 minutes. That should be enough. This session continues from the last one. In a moment, I’ll explain again why this matters for our team. I really want everyone to understand this deeply. It’s a technique not widely used in Erlang, which makes it a bit special. Once we figure this out, we can apply it to other projects too. **[14:12]** Alright, Minh Lưu, you’re up. I’ve got the slides ready. I’ll review a bit from the previous session so everyone can recall it better. That one included a behavior pattern, basically a way to define a module. You predefine some hooks, then handle different scenarios based on those. It’s kind of like a scaffold for core logic. **[14:49]** Then you implement those hooks. The two most common are gen_server and gen_statemachine. For most modules, you can just write a server. Especially for simple state machines, gen_server is usually enough. But depending on the use case, you have to be careful, don’t just use them interchangeably. **[15:14]** “Gen” stands for “generic” generic server. You should only use gen_statemachine when you really need more advanced features. For example, inserting events manually into a stage, or triggering a specific action when transitioning between stages. Those are things gen_server doesn’t handle well. **[15:36]** If you want to automatically run an action when entering a new stage, that’s called a state entry. Or when you want to set timeouts between steps. In practice, gen_statemachine is used when you’re building something persistent—something that needs to hold state over time. **[15:59]** Like a TCP connection, for instance. State machines are commonly used for that. When you’ve already defined a fixed set of states and need the connection to persist, gen_statemachine is a solid choice. For simpler stuff, gen_server is enough—no need to complicate it. Today, I’ll walk you through an actual code example so it’s easier to understand. **[16:24]** Like Minh asked last time why use Erlang when Elixir can already handle this? And yeah, that’s true. You can implement behavior in Elixir the same way you do in Erlang. So today, I’ll do the example in Elixir so everyone can compare and see which approach is more practical. **[16:49]** Elixir code looks a bit more readable. Do we have the slides? Here’s the one on gen, let me show you more detail so you can see how it works. Okay, I’ll insert the slides now. We’ll build a module that connects to a Redis server over TCP. I’ll keep it simple, just two stages so it’s easier to follow. **[17:34]** Two stages only. This module sits between the user and the Redis server. It implements methods to establish and maintain the connection. For example, when the process starts a connection, all user requests will return a “disconnected” status. The user has no idea what the actual connection state is they only see what the proxy process returns. So, two stages: when the process starts, it’s in “disconnected”. **[18:21]** It’ll try connecting to Redis. If the connection succeeds, it switches to “connected”. If the connection fails or drops, it goes back to “disconnected” and retries. The incoming requests client event requests are received as events. These can arrive in either disconnected or connected state. If disconnected, we just return that state to the client. **[18:41]** If connected, we forward the request to Redis, get the data, and return it to the client. Why a state machine? Because we need features like insert event, like I mentioned. Here let me zoom in so you can see. **[19:39]** First, we implement the behavior in the state machine and define the data structure. It has two parts: State represents the current stage of the module, and Data carries information between transitions—like host, port for connecting to Redis DB, and a map of client requests with client IDs. When the process starts, the first step is to connect to Redis in the background, while returning “disconnected” to the user. **[21:04]** First, we define the callback mode with two things: the state function which means naming the functions in the module according to the stage name, for example, if the stage is disconnect, then the module will automatically run the disconnect function to handle it based on the name and arity and the state enter, which I’ll explain in a bit. We start with the init function, which returns next_event, meaning the module will automatically insert an internal event called internal_connect, with data being the host and port to connect to the Redis server, and then it immediately returns the disconnect state. When it returns disconnect, it jumps into the disconnect function to handle things. The disconnect function with internal_connect will open a TCP socket using gen_tcp to connect to the Redis server and start setting up the connection in the background. **[21:49]** The part about state enter, I’ll explain that in a bit. That’s what the state function means. After that, we begin with the init function like I mentioned earlier. What does it do? It’s simple: at the start of the function, we use a term called next_event. What’s next_event? It means the module will insert like automatically insert an event into its own queue. This event is internal_connect, using the data host and port to connect to the Redis server, and then immediately return the state disconnect. **[22:43]** When it returns the disconnect state like that, the first thing it does is run the disconnect function to handle the logic. What does disconnect with internal_connect do? First, it opens a TCP socket using gen_tcp to connect to the Redis server. But then I realized there are too many details, so I thought maybe I should try combining a few of the functions. You mind if I jump in and show you the part where it defines the two stages? That part looks a bit messy. Where exactly are the two states defined? You can see here it has a list over there, and we just have two states. **[23:48]** Here are the two states, and four overlapping functions between disconnect and connect. Minh has four overloads of connect, but only two states, which is normal. In Elixir, function overloading works based on the parameter list, so it knows which one to run. What about the part where the state transition happens? Oh right, it’s inside each function. **[24:42]** For example, in this connect function, when the connection is successful, it returns an atom next_stage, which switches the state to connect right there, along with the data. Got it, that’s the part that triggers the state transition. But with each overload like that, calling it implicitly like this is that okay? Normally, stuff like this should have a controller to manage it. Calling each one like this feels a bit messy. If there are 10 stages and we define and call them all this way, it becomes impossible to manage. **[25:01]** Right at this part here, in our backend. Since we’re using state functions, there’s something called a handle_event function. When we switch to this mode, we only need to define a single function called handle_event. Just one function to manage all the states in there. If you want to write it that way, the system lets you choose between defining per-state functions or defining one handle_event function. **[26:14]** Now where’s the diagram, have you looked into this or used it before? For a clearer picture, I copied a connection library that also connects to TCP. It’s written using gen_server, doesn’t use a state machine. It’s built kind of like a button logic. If the connection fails, it backs off and retries. It also manages users inside a map. But it’s a bit longer, you have to reimplement some of the built-in things like timeout, for example. It doesn’t come built-in so you have to code that manually. And to answer the earlier question yes, I just recently learned and started working with this. I’ve known about it for a while, but only recently started applying it. So how did it feel when I actually got into it? Why is it important? Because it defines some structured ways that make things more convenient. For example, for handling timeouts, it defines that based on the data we return. **[27:47]** Here’s an example. When your connection drops, it jumps into the disconnect function to handle it, and you can return an atom timeout along with a time value. After that time passes, it’ll automatically jump into this function to process it for you. Yeah, so it helps make these things more convenient. You could write it using gen_server too, but that would be a lot longer. Okay, okay, thanks Minh. Minh Trần, any questions? Anyone else? **[29:14]** Let’s have Minh Trần code this, and code it in Elixir. Since you know it already, have you touched this part before? And ask questions to help spread the knowledge to the team. So here’s how it works: the fundamental difference in programming with our team is that among all the modern programming languages right now, none of them have a built-in library for state machine management like Erlang. Erlang is the only one that was born for running these kinds of automatic systems, not from the traditional client-server mindset where a server just sits there waiting for requests. **[29:30]** This is built-in, right? And with this kind of built-in feature, when you write code, two things happen. First, it forces the whole team to learn this language, and once they start using the tooling, it shapes a shared mental model a way of thinking that everyone can follow. When you encounter the right use case, you pull out the right tool and solve the problem by thinking about it this way. **[30:07]** Back when we were doing things like the C4 model, we were already touching this stuff, weren’t we? It gives you the tooling. The second benefit is that it unifies everyone’s mindset. Of course, you can still code using gen_server the traditional way, that’s totally fine. No problem with that. But what makes Erlang special is that it has this built in. **[31:13]** Once the team really gets this, managing a codebase through state machines, switching between states and objects, helps you keep the codebase much more maintainable. You avoid writing implicit code, bouncing it around in different places, not knowing where the transitions are actually happening. Instead, you can focus more on the logic and the structure, rather than getting caught up in the underlying data. Otherwise, in big codebases, bugs will pile up everywhere, and if you don’t look at it with this kind of mindset, it gets messy fast. That’s why this thing is special. For Erlang, this is what makes it stand out. In Elixir, there’s no official library built like this, so you still have to call into Erlang directly. **[32:08]** Alright, that was a quick wrap-up of Minh Lưu’s talk. If he’s going to do a follow-up session, I’d recommend something a bit more complex, something more realistic. The last example only had two stages, which still looked simple. Maybe look for some open-source code from other teams, ones that manage more complex state. There’s this example I saw from another group that manages WebSocket state—it had a ton of stages. That example also used gen_statemachine, and the file was over a thousand lines. When they consolidated the functions, the structure became clear it wasn’t just code pushing back and forth randomly. There was a dedicated manager handling everything. So even if you lose track and come back later, it’s still easier to read than trying to understand a bunch of functions with custom names. That gets exhausting fast. **[34:18]** Building a shared mental model within a team is super important. Thanks, Minh Lưu. Now over to Minh Lê. Yeah, let me check how many minutes I’ve got. Ten minutes, right? Okay, ten minutes. I think I have four posts already? Back then, the consulting team had the idea of doing a weekly series—one post per week summarizing info related to our testing side. But it wasn’t too deep on testing more of a general roundup. The first one I wrote was back in mid-December last year. It covered the release of Google’s Gemini 2.0 and OpenAI’s model that generates video chains. **[34:38]** They had visuals showing it applied to patients, or healthy people wearing something like smartwatches to track their heart rates like what we wear. In the consumer space, the focus was more on secret tech, like rendering video similar to Sora. On the crypto side, they’re also embedding AI into fintech, gaming, infrastructure, and so on. **[35:21]** Same goes for Y Combinator. They’re also saying AI should be applied to everything right now. At the moment, they’re encouraging research into stablecoins. In the past, they were promoting Bitcoin and Ethereum for payments. But after testing it on the market, they realized it wasn’t a good fit. So now they’ve shifted to studying stablecoins—aiming for enough market share that companies would invest money into R&D and build payment solutions. **[36:21]** Here I’ll briefly mention a product an AI agent platform on Solana. They’re positioning it as a platform to build AI agents. These agents help manage wallets, generate tokens, trade automatically basically automating the kind of stuff crypto and DeFi users normally do. This product helps people get it done easier with AI support. That was the first post. Moving on to the second. Out of the four, there are a lot. Now the real question is out of the four posts from last month, what do I think actually benefits our team? **[37:13]** Yeah I think we’re on the right path now focusing on AI tech getting used to agent stuff blockchain and all that it’s growing fast booming really hot right now probably gonna see a lot of products diving into that soon the other tracks like what Y Combinator or a16z suggest might be a bit out of reach for our market so harder to jump in but last week I saw this report about money flow in and out of Southeast Asia for Q4 2024 these were the top sectors getting capital. **[38:23]** First one’s challenger banks different from traditional banks fully digital I think in Vietnam we’ve got one that’s sorta digital but it’s not really what they define as a challenger bank like Timo they usually call that a neobank challenger banks are the ones that have a banking license they can issue their own digital banking products. **[40:08]** Neobanks in Vietnam usually sit under a traditional bank’s license so they can’t release their own banking products in Southeast Asia VCs are pouring money into challenger banks because they think it solves the access to finance problem in underserved areas more so than crypto. **[40:30]** I checked salary data too for IT in Southeast Asia Philippines is super competitive big population education’s solid IT workforce is huge working with foreign companies English is good pricing better than Vietnam even. **[41:26]** Vietnam saw a huge drop in Q4 over 80% down meanwhile Philippines is booming ecom’s growing fast all the digital stuff kinda like where we were three or four years ago now they’re getting the investment okay interesting scroll up a bit everything above sounds like it’s tied to money right banking currency finance heavy focus on finance seems like that’s where SEA is betting big. **[42:39]** If that’s the case maybe next week we can sit down and go through some potential lists try finding those ecosystem maps or system overviews from them can we find that yeah I’ll look for it most reports have those yeah okay anything else besides that this week’s quiet it’s Christmas not much news kinda dull I did bookmark a few new blockchain products they’re getting heavy capital inflows and locked funds blockchain huh show me Liquid yeah hold on they shared it in the chat already it’s solid. **[44:19]** If that’s the direction then for writing this post I think there’s a good angle if you can frame it this way our team’s slogan from the start has been empower innovation meaning we look for where innovation is happening to find ways to work with them support them even invest if we can biggest value from doing this is spotting where innovation is instead of broad headlines we can pinpoint where the market’s pulsing here and there that’s where innovation’s happening inside that what’s the business model financial model answer those clearly it lines up with our core direction and helps us analyze business cases better too. **[47:25]** Try that angle yeah thanks Minh we’ve been missing that knowledge has been kinda scattered this perspective helps when we review projects just ask where’s the sale where’s the money another way to ask is where’s innovation happening who’s building something new there’s where we can jump in and give it a look the stuff that already exploded we just retain and patch it up boring stuff alright that’s it for this part now quick year-end wrap up everyone’s going offline after this quick one Huy and Thành got your sections ready done already looks like it. **[47:50]** This year the market shifted so much all the assumptions from before are out the window even our own people have moved around a bit right **[48:53]** Our direction’s also shifted we used to focus on enterprise but then AI came and wiped out the whole thing now there’s chaos heading into finance and blockchain is where the flow is AI’s booming yeah but actual enterprise use still low everyone’s just chasing hype main trend is still around finance. **[49:55]** Turns out our engineering team’s been researching and learning those exact topics so for year-end announcements how many awards do we have team got four awards plus one from community there’s one top-level award too others are kind of honorable mentions these are to recognize high performers across key areas of our team okay let’s announce them seven awards based on four main ones right. **[51:05]** One team award then three others first one’s for the person who executed the AMA model best second one’s team lead of the year whoever led their squad the strongest third one’s for top consulting performer two projects that got great feedback both from team and from the client third one’s also a team award either for successful inhousing or trust-building and upselling for that team. **[53:38]** Final award goes to the community folks supporters who aren’t official team members but still worked with us joined activities shared stuff so that’s four right Developer of the Year is based on MMA model meaning mastery autonomy second is research-oriented team lead third is consulting three individual awards one team award for the most impactful project others that didn’t have impact won’t be mentioned last one’s the community award and wait who’s even in the community this year felt pretty quiet right yeah someone did work with us a few months though. **[54:26]** Alright let’s do a quick announcement let people in-out easily okay if I make it formal it’ll take too long so let’s roll with it someone react on Zalo or Slack so we can screenshot it two VIPs already confirmed good okay second award Thành you got that one what was it again check the notes yeah. **[55:58]** Lead give us a quick reaction wait is this one individual yeah okay can we do a brief overview so far performance looks about the same as previous years not sure on the details go ahead yeah Huy might add more in a bit from what Thành saw and how Phúc did honestly in previous years Phúc mostly worked on internal and consulting this year moved to team Yolo. **[57:21]** Honestly his role was kinda light compared to backend expectations before he focused mostly on iOS at first folks were skeptical about him but heard he adapted well in like five six months the team over there seemed pretty happy with him and they’re known to be tough Huy probably has more accurate comments since it was his project wait is that your feedback Huy he’s talking about me well I think he handled quite a lot pushed back where needed made suggestions. **[58:46]** I think Thành picked Phúc because he met people’s expectations before he’d finish projects but stay quiet didn’t really engage his skills were always good but this year went beyond that like picking up new styles getting into loops exploring JavaScript TypeScript stuff he hadn’t touched before plus started getting into deadlines client timelines and pushing back like recently someone asked if he could finish fast and Phúc said nope not gonna make it let’s do it slower that’s a good sign and then he started getting assigned tougher development tracks not necessarily best overall but his trajectory’s impressive alright Superman Phúc are you coming up to say something. **[55:58]** Lead, give us a quick reaction. Wait, this one’s personal, right? Yeah. Okay, can we go over it briefly? So far performance seems like previous years, not sure on the details, over to you. Right, Huy might give a more detailed comment later. But based on what Thành saw about Phúc this past year, actually in previous years, Phúc mostly worked on internal projects and consulting. This time he moved over to the Yolo team. **[57:21]** Honestly, the role was kind of weak compared to backend depth expectations. Before that, Phúc was mainly focused on iOS. At first the team over there was skeptical about him, but apparently he adapted really well. In five or six months, the team there seemed to rate him highly, and I heard they’re pretty tough. Huy probably has the more accurate comments, since it was his project. Hey, this guy’s commenting about me. Actually I think those who worked on this contributed a lot, handling pressure, estimates, all that. **[58:46]** But I think Thành picked Phúc because he matched expectations well. He’d done projects before but stayed quiet, didn’t communicate much, just got it done. Super talented, but this year he went way beyond that. For example, picked up new styles, loops, worked with JavaScript, TypeScript, even though before he wasn’t really involved with those. He also started reviewing stuff with clients, catching issues with deadlines. The best was when someone wanted to rush something and Phúc said no way, it won’t make it, take it slow. That was a good sign, and then he started being trusted with tougher, more intense features. Not necessarily the best, but probably the most solid expectations-wise. Alright, Superman Phúc. You coming up to speak? **[61:03]** How am I supposed to sit like this, I just plugged in my headphones. I was pretty surprised, honestly. Was catching a ride to go do charity stuff and didn’t expect this. Don’t really know what to say, but seems like a lot of people heard already. Oh hey, Ngọc Thành just joined, long time no see. Phúc, can you hear us? He’s muted, I guess. I’m outside right now, so this is the second award. Do I think I deserve it? A bit shy to say, but honored. Yes, that’s right. Next award is from Huy, let’s go ahead and present it to the Yolo core team. Okay, Yolo team meaning? **[62:28]** Yolo’s considered a standout team. Yeah, agreed. This is the last award, the rest goes to this person. This one goes to someone who spent about 2–3 months interning with us, mostly researching software-related stuff. **[63:20]** Actually, Đạt had already been pretty active on our server even before interning. Even after the internship ended, he kept contributing to AI builds. The posts he shared got forked and reshared quite a bit by core team members. A great example of someone we want to support in the community. Đạt should probably say something. Đạt, the community award is yours. Where are you now? **[64:26]** I’m outside right now, still on the way. Everyone’s done with meetings already? Thanks so much for the time. Honestly, Tom and Thành helped me a lot during onboarding and sharing stuff back to the team in a way that could be understood and used. Anything else? No, I think that’s it. Thanks again for your time. **[65:11]** The way you’ve been sharing what you read with everyone is super appreciated, Đạt. Even now, in terms of internal knowledge sharing, that’s been one of the most valuable things. Because innovation is always shifting, and we haven’t had a chance to work closely together yet. But in the bigger picture, sharing cool ideas with each other like that is really meaningful. Thanks, Đạt. Now, final award, Thành. After that we’ll wrap up. **[66:14]** Developer of the Year award goes to Biên. Everyone, give a quick in-out reaction. Biên, where are you? Please share the reason behind the nomination, go ahead. Alright, hold on everyone, okay. Last year and the year before, as you all know, we had this idea posted in the group we wanted to execute based on the AMA model: mastery, autonomy, and meaning. The way we determine the winner is by observing who in the team executed that model the best over the past year. **[68:23]** This is something the team really wants to roll out, especially now that AI can help with unit work, solutioning, design systems, all that stuff. It’s become even more important lately. Biên’s been one of those folks who really seems to embody the core goals of the team most clearly. Everyone really enjoyed working with Biên recently, so that’s basically the main point. **[69:18]** Biên, please say a few words, then we’ll move to the final part. What do you think, based on Thành’s comments? Thanks everyone. Even if things change, that’s alright. Let’s wrap this up here, that’s it for Biên’s part. **[70:21]** Later, before we all head out to wrap up the year together, we’ve got a few new things to reorient after Tết. This is basically the final weekly sync, right? Next week we’re not meeting anymore, since we’re cutting the frequency down to once every two weeks. The topics we’ve been sharing starting from keywords and ideas are for us to keep learning and exploring to develop ourselves. Since the syncs are now biweekly, the next one will be the final one in January. After Tết, we’ll pick it up again. **[71:49]** After Tết, the direction of our team and the projects we’ve been building especially the ones Minh Lê’s been involved in are leaning more into innovation in those specific fields. Even the management team sees that. Those types of projects are starting to come in, and we’ve been building them. Our products are heading that way too. So after Tết, there will be a very interesting phase of startup-style building and joining the build-in-public trend, especially after many engineers were laid off. Some of them have started building on their own, launching businesses, participating in build-in-public communities, launching a token, or deploying alpha features. I’ve noticed this natural flow of four themes coming together, and it’s led our team in a direction I think will continue through mid-year—focused more on the finance sector in general. **[73:07]** If we plug that framework in, it’s almost like a repeatable button. We can do consulting based on that, and at the same time apply all the engineering knowledge we’ve built up from working on regular products. Products used to just be about datasets lists, arrays. Now we’re moving toward more complex problem-solving, scaling, and building real applications. If you want to self-detect and manage your own trend in the end market, that’s also possible. It’s a really interesting direction, and probably after Tết, we’ll start revealing more during future syncs. With that direction in mind, the team’s strategy will influence personnel decisions a lot too. **[74:28]** Some changes will kick in at the start of next year. With that in mind, I want to temporarily move away from the idea that our team is default-remote. Meaning, it won’t be assumed that everyone just works remotely by default anymore. After the last few syncs, I’m hoping we can reset our rhythm a bit. Some of our current projects feel a bit scattered, and we’re not quite sure how to handle that yet. **[75:15]** The whole project vibe feels a bit too casual. I’ve been labeling it as retainer work just show up and coast. So I want to announce a new policy: after Tết, everyone in Saigon needs to start working at the office again. We’re removing the remote-default setup for the Saigon Hub. Instead, we’ll move to a hub-based working model. **[76:07]** We have two, even three, official hubs: Saigon, Danang, and Hanoi. Everyone should find a place to sit together again, rebuild that physical connection. You’ll be expected to show up 3 days a week. Yeah, those are a bit different. Over the past stretch, working remotely has been great for the “alone zone.” Alone zone works when knowledge is stable and not changing. **[77:05]** But when the market shifts, the teams that communicate the most are the ones who adapt and grow the fastest. So if you’re working remotely, there’s a high chance of falling behind. We’re even thinking of reopening some hiring, I’ll repost the requirements soon. We’ll restructure things. Remote worked great when the knowledge was stable, but now that things are moving, you need those dense information zones to evolve faster. **[77:43]** That’s why things are shifting the way they are. Either you need to be extremely active online or you meet people offline. That’s the hard rule. With this policy, you’ll have one month to figure out what your setup looks like. Given the way the market is moving, Meta just laid off another batch, didn’t update the rest, dropped 3,600 people everyone’s skeptical about building new stuff. So fully remote opportunities are starting to shrink. **[78:35]** We’re not asking anyone to change overnight, but this is the direction. First, everyone in Hanoi and Saigon should start sitting together again. I’ll try to arrange teams by region so you can get back into your flow. **[79:29]** So that’s 3 days per week. At the moment, with our current members—Thành, for example he’ll relocate to Saigon sometime mid-year. Huy Nguyễn is already running the Saigon office. Folks who’ve been going in regularly shouldn’t have any issue. We’ll test this out first, and it’ll become the official policy after Tết. Everyone we know who’s currently based in Saigon will be required to follow it. **[80:14]** That’s the main change in how we operate. The second change is: there will be no ref-sharing this year. In the past, we had a ref-sharing program, but this year there’s only the 13th-month salary. About 90 minutes ago I pushed the button, so everyone should have received it by now. It’s calculated as the average of your past 12 months’ salary. For newer folks, it’s prorated by month. But no extra sharing this year. **[81:26]** The sharing program usually kicked in when revenue stayed stable or grew. In those cases, I’d take a percentage of revenue and distribute it based on team seniority. Someone with 8 years would get more than someone with 5, etc. But this year, there won’t be any of that. That’s a quick summary of the core changes in how the team’s operating. If anyone wants more info, Inno posted an article earlier have you all read it? Alright, take a look at the screen. There’s a post there. I think the way we’re running things now is going really well. Everything’s clicking together. **[82:41]** Now it’s just a matter of choosing the right market and spotting opportunities that can trigger major income jumps that’s the real goal. With our current model and the way we operate, I’m really happy with how things are going. If there’s nothing else, enjoy dinner tonight with the team at either of the two meetup spots. We’ll reconnect after Tết with more detailed plans, new recruitment, and new directions especially around the finance sector. I think there’ll be a lot of breakout financial opportunities ahead.
