Audit, rewrite, and tighten a CLAUDE.md / AGENTS.md file so it actually helps a coding agent instead of bloating its context. Handles repos that use either file name, both names, nested AGENTS.md files, or one file symlinked/aliased to the other. Use this skill whenever the user wants to review, clean up, fix, shrink, restructure, or improve a CLAUDE.md / AGENTS.md file
