Adds a rule that teaches Cursor to hand the user a rendered-document link instead of raw markdown when they ask to share or present what the agent wrote. Encoding is base64url with a 2-byte version prefix, documented at https://www.magzdown.com/docs.

File: rules/magzdown-share-as-document-cursorrules-prompt-file.mdc, listed under Documentation.
Source repo: https://github.com/xarl3z/magzdown-agent-tools. I'm the author.

Adds a Magzdown sharing rule for converting agent-generated Markdown into a rendered document link. Adds a README entry that links to the rule.

Changes

Magzdown sharing

Layer / File(s) Summary
Rule triggers and sharing safeguards
rules/magzdown-share-as-document-cursorrules-prompt-file.mdc
The rule defines Markdown document triggers, explicit confirmation, sensitive-content restrictions, and handling for uncertain content.
Link encoding and response flow
rules/magzdown-share-as-document-cursorrules-prompt-file.mdc, README.md
The rule defines URL encoding commands, a size guard, and titled Markdown-link output. The README links to the new rule.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to caedf

The new rule is intended to turn requested Markdown sharing into a rendered document link, but its file-matching condition may prevent activation for chat-only requests without a matching Markdown file. The feature could therefore be silently skipped, so merge should wait for the activation path to be corrected or explicitly accepted.

P1 Badge Populate globs for this scoped rule

With alwaysApply: false, an empty globs field violates the repository's required scoped-rule frontmatter and makes the rule-hygiene job in .github/workflows/main.yml fail. I reproduced this against the target commit with node scripts/check-repo-hygiene.mjs; add applicable patterns or, if this guidance is intentionally universal, set alwaysApply: true.

Useful? React with 👍 / 👎.

Both review points fixed in the latest commit:

  • globs was empty, which failed rule-hygiene. Now **/*.md, **/*.mdx, and node scripts/check-repo-hygiene.mjs passes locally.
  • Sensitive data: the document travels inside the URL, so the link is the document. Added a "Before you share" section that tells the agent to ask before creating a link, and to refuse content carrying secrets, personal data, or anything marked confidential, offering a redacted version instead.

On the promotional flag: I wrote the tool the rule points at, and said so in the PR description. The rule itself is a normal Cursor rule with no tracking and no account, and the encoding spec is public at https://www.magzdown.com/docs. Happy to drop it if you would rather not carry vendor-specific rules.

…r rule globs

Raised in review on PatrickJS/awesome-cursorrules#364: the document travels
inside the URL, so the link is the document. All three integrations now tell
the agent to confirm first and to refuse confidential content.

Cursor Rules MDC globs alwaysApply false description-based rule selection when no matching file is in context official documentation

💡 Result:

In Cursor, rule application is determined by three frontmatter fields in .mdc files: alwaysApply, globs, and description [1][2]. When alwaysApply is set to false, the rule's inclusion is decided based on the other fields or explicit manual intervention [1][3][2]. The specific behaviors for alwaysApply: false are as follows [1][2]: 1. Apply to Specific Files: When globs are provided, the rule is automatically attached whenever a file matching the specified pattern is in the context [1][3][2]. 2. Apply Intelligently (Agent-Requested): When globs are omitted but a description is provided, the Cursor Agent reads the description and decides whether to include the rule based on its relevance to the current task [1][3][2]. 3. Apply Manually: When both globs and description are omitted, the rule remains inactive unless you explicitly @-mention it in a chat session [1][3][2]. If alwaysApply is set to true, the rule is included in every chat session, and both globs and description are ignored [1][3][2]. For a rule to function in "Apply Intelligently" mode, a clear description is required; without one, an otherwise intelligent rule will default to manual-only mode and will not trigger on its own [4]. All project rules must use the .mdc extension to be recognized by the system [1][2].

Preserve chat-only activation for sharing requests.

When globs is set, Cursor automatically attaches this rule only when a matching file is in context. A chat-only Markdown response may have no matching file, so the rule may not load. Remove globs for description-driven activation, or add a separate chat-available rule. Test both chat-only and matching-file flows.
