fitness-functions

Put your architectural rules under test!

Validate the fitness of your AWS solutions, without the heavy lifting!

Bring order to chaos. Level up your JS application architecture with Module Composer, a tiny but powerful module composition utility based on functional dependency injection.

Architecture-fitness CLI for AI agents and CI: deterministic multi-language gates, Balanced Coupling scorecards, SARIF, and agent repair tasks.

achp enforce architectural rules as errors values or unit tests

Linters check lines. maat checks the agreements your team made about the codebase — layer boundaries, module rules, one-place policies — with a committed history of every violation and every decision.

Guided evolution for data transformation projects

Measure and govern microservice boundary granularity: one score for whether a boundary adds value or is a distributed monolith.

Generic policy validator for the RM Method — rm-validate init/check/explain, driven entirely by rm-policy.yaml. Apache-2.0.

Architecture as Code: CLI, multi-language SDK (TS/C#/Java/Python/Go), source scanners and rule engine. Scan, validate, and diff your architecture in CI/CD.

Bedrock — enforced Next.js / React engineering standards for Claude Code, packaged as a plugin: Nx monorepo & micro-frontend architecture, design tokens, atomic design, React Query, accessibility, TypeScript, plus enterprise governance (ADRs, tech radar, CI fitness functions, policy-as-code, managed settings).

A payment system built by an AI agent from a frozen spec, zero hand written tests, guarded by a four layer verification pyramid (structural, behavioral, agent judgment, mutation). 73.1 percent mutation kill rate.

Architecture fitness rules for .NET modular monoliths — including Blazor markup, by reading the Razor compiler's own generated C#.

ADAF — AI-driven architecture framework: feed it to an AI (Claude/GPT) to generate a proven backend architecture, then verify it with ArchUnit conformance tests. Spec → Scaffold → Conformance.

When agents write the code, engineers own the intent. A short field guide to the shift.

Fitness Functions oriented for Frontend Development

Compiles your conventions into native toolchain gates (ESLint, clippy) — deterministic, local-first, $0 LLM in CI. Its own AGENTS.md is executable. Docs lie; tests don't.
