Asked Claude to review and fix them. It made things different, not better.
So I built a linter. 42 rules covering structure, content, efficiency, governance, maintenance. Deterministic checks first, semantic validation for the rest.
Currently supports CLAUDE.md. Cursor, Copilot, Codex adapters coming.
v0.0.1. Open source.
CLI + MCP: https://github.com/reporails/cli

Early days. Looking for feedback, bug reports, and contributors.
