What it does
A tool that checks your coding agent's edits against the rules in your project files such as AGENTS.md or CLAUDE.md. When an edit breaks a rule, it flags it so the agent fixes it. It hooks into Claude Code, Codex, OpenCode and Pi.
Use cases
- 01Flag an edit that breaks a rule in AGENTS.md
- 02Catch duplicated logic or oversized files
- 03Apply the same rules across several coding agents
