CLAUDE.md Checker

Paste your CLAUDE.md and get a scored list of problems: leaked secrets, broken @imports, contradictions, and instructions that should really be hooks, permission rules or skills. Each finding quotes the line and gives a fix you can paste.

Fix it for me, $12 same-day

Prefer to do it yourself? The $7 cheat sheet covers the same ground.

What it checks

Checks come from the same rubric the paid rewrite uses, grounded in the Claude Code docs as of Oct 2026.

    Honest limits: this is deterministic pattern matching on one file. It can't see your settings.json, the files you @import, or your repo's config, so it can't tell whether an import resolves or whether prose disagrees with .prettierrc. Expect the occasional false positive, and some misses a careful read would catch.
