Audit and improve CLAUDE.md files in repositories. Use when user asks to check, audit, update, improve, or fix CLAUDE.md files. Scans for all CLAUDE.md files, evaluates quality against templates, outputs quality report, then makes targeted updates. Also use when the user mentions "CLAUDE.md maintenance" or "project memory optimization".
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# CLAUDE.md Improver
Audit, evaluate, and improve CLAUDE.md files across a codebase to ensure Claude Code has optimal project context.
**This skill can write to CLAUDE.md files.** After presenting a quality report and getting user approval, it updates CLAUDE.md files with targeted improvements.
## Workflow
### Phase 1: Discovery
Find all instruction files in the repository, skipping dependency and VCS directories:
```bash
find . \( -name node_modules -o -name .venv -o -name .git \) -prune -o \
\( -name "CLAUDE.md" -o -name "CLAUDE.local.md" -o -name "AGENTS.md" -o -path "*/.claude/rules/*.md" \) -print \
2>/dev/null | head -50
```
**File Types & Locations:**
| Type | Location | Purpose |
|------|----------|---------|
| Project root | `./CLAUDE.md` or `./.claude/CLAUDE.md` | Primary project context (checked into git, shared with team) |
| Rules | `./.claude/rules/**/*.md` | Topic-specific instructions; loaded at launch, or only for matching files when the rule has `paths:` frontmatter |
| Local overrides | `./CLAUDE.local.md` | Personal/local settings (gitignored, not shared) |

The line at the top of this page pins the label git:20261015.42513a8, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
