Review Claudemd

/review-claudemd — CLAUDE.md Health Check

Scan all CLAUDE.md and rules files for issues that waste tokens or cause confusion.

Checks

1. Dead File References

For every file path mentioned in CLAUDE.md files and .claude/rules/*.md:

• Verify the referenced file exists using Glob
• Flag any missing files as "dead reference"

2. Orphaned Skills/Agents

• List all directories in .claude/skills/ and .claude/agents/
• Check each is referenced in root CLAUDE.md
• Flag unreferenced skills/agents

3. Token Bloat & Cache Analysis

For each CLAUDE.md file and .claude/rules/*.md file:

• Count bytes and approximate tokens (bytes / 4)
• Flag files over 2KB as "consider splitting or moving on-demand"
• Flag duplicate content between CLAUDE.md and rules/ files
• Budget check: Root CLAUDE.md should be under 6KB (~1500 tokens). It's a router, not a manual. If over budget, identify sections that are process documentation (things the model already knows) vs gotcha documentation (things the model would get wrong without). Move process docs to on-demand files.
• Total context cost: Sum all always-loaded files (CLAUDE.md + rules/*.md + MEMORY.md) and report total. Target: under 20KB (~5000 tokens) for always-loaded context.
• Cache efficiency: Check if any rules/ files are also available as on-demand skills (duplication wastes cache). Files that are only relevant for specific workflows (Ralph, deployment) should be in .claude/contexts/ not .claude/rules/.

4. Consistency Checks

• All skills in CLAUDE.md On-Demand Skills table have matching .claude/skills/<name>/SKILL.md
• All agents in CLAUDE.md Custom Agents table have matching .claude/agents/<name>.md
• All rules in Scoped Guidance table have matching files
• Anti-patterns files referenced in anti-patterns.md index all exist

5. Deprecated API Mentions

Search all CLAUDE.md files for known deprecated patterns:

• forwardRef (React 19)
• useContext instead of useUtils (tRPC v11)
• getServerSideProps (App Router)
• tailwind.config.ts (Tailwind v4)
• nonempty() (Zod v4)
