Rules evaluator

Discover every Claude Code rule file, validate its structure and paths globs against the real project, then review each rule with the user so the rules directory ends in better shape than it started.

This skill covers Claude Code instruction rules in .claude/rules/ and ~/.claude/rules/. It does not cover Codex .rules files, which are Starlark command-approval policies, not instructions. See "Codex" below.

When to use

• Writing .claude/rules/ files for the first time
• A rule never seems to apply, or applies to everything
• Moving @ imports from CLAUDE.md into path-scoped rules
• Periodic hygiene: are these rules still accurate and useful?
• After onboarding to a new codebase
