# claude-md-review

This skill audits CLAUDE.md files for vague rules, broken paths, and context bloat. It helps when an agent ignores instructions or constantly rediscovers project context.

## What it does

Because `CLAUDE.md` loads into context on every session, unneeded lines waste token budget turn after turn. The skill inspects the target file (defaulting to `./CLAUDE.md`), checking nested copies and global rules in `~/.claude/CLAUDE.md`. Using `Read`, `Glob`, and `Grep`, it verifies whether referenced paths and scripts match the actual repository.

The review flags unfalsifiable directives like "write clean code" and suggests testable rules instead. An incorrect test command in instructions causes more damage than having none, so the check validates commands against actual repo config files. It also spots dead file paths and raw directory trees.

The skill will not edit files on disk without permission. It delivers a structured report with line numbers, suggested rewrites, and lines marked for deletion.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add wesammustafa/Claude-Code-Everything-You-Need-to-Know --skill claude-md-review -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/claude-md-review/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/claude-md-review/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add wesammustafa/Claude-Code-Everything-You-Need-to-Know --skill claude-md-review -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/claude-md-review/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add wesammustafa/Claude-Code-Everything-You-Need-to-Know --skill claude-md-review -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/claude-md-review/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install wesammustafa/Claude-Code-Everything-You-Need-to-Know claude-md-review
```

2. **Manually: put the files in place**
- File: `.github/skills/claude-md-review/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add wesammustafa/Claude-Code-Everything-You-Need-to-Know --skill claude-md-review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/wesammustafa/Claude-Code-Everything-You-Need-to-Know --path .claude/skills/claude-md-review
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/claude-md-review/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add wesammustafa/Claude-Code-Everything-You-Need-to-Know --skill claude-md-review -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/wesammustafa/Claude-Code-Everything-You-Need-to-Know/tree/HEAD/.claude/skills/claude-md-review/SKILL.md

## When to use it
- identify vague instructions and replace them with checkable diff criteria
- detect dead paths, deleted files, and outdated build commands in `CLAUDE.md`
- trim context bloat caused by raw file trees and generic coding advice
- resolve conflicts between root, nested, and global instruction files

## Example prompts
- Audit my ./CLAUDE.md and highlight lines worth deleting
- Why does Claude keep forgetting my project instructions in this repo?
- Review ~/.claude/CLAUDE.md for dead paths and stale commands

description: Audit a CLAUDE.md file for the patterns that actually degrade Claude Code's output — vagueness, unnamed files, stale facts, and bloat. Use when asked to review, audit, improve, shrink, or fix a CLAUDE.md, and when a project's results feel inconsistent or Claude keeps rediscovering the same context.
when_to_use: Trigger phrases include "review my CLAUDE.md", "why does Claude keep forgetting", "my CLAUDE.md is too long", "Claude ignores my instructions", "audit project instructions".

# CLAUDE.md Review

Audit a `CLAUDE.md` against the failure modes that actually cost output quality.

**Premise:** `CLAUDE.md` loads into context on every single session, so every line is either paying rent or costing you tokens on every turn forever. Most "the model isn't following instructions" problems are instruction problems.

## Steps

1. Read the target file (default `./CLAUDE.md`; also check `~/.claude/CLAUDE.md` and any nested `**/CLAUDE.md` if the project has them, since the closest one wins).
2. Score each dimension below and quote the specific lines that fail.
3. Output the report format at the bottom. Propose concrete rewrites, not "consider being more specific."

## What to check

**Specificity** — the highest-leverage dimension.
- Flag unfalsifiable directives: "write clean code", "follow best practices", "be careful", "use good naming".
- Every rule should be checkable by reading a diff. `"Refactor functions over 40 lines"` is checkable; `"keep functions short"` is not.

**Named anchors.**
- Rules that reference "the config", "our API layer", or "the usual pattern" force rediscovery every session. Replace with real paths: `src/config/env.ts`, `src/api/client.ts`.
- Verify every path, command, and filename mentioned still exists. Report the dead ones — a `CLAUDE.md` pointing at a deleted file actively misleads.

**Staleness.**
- Version numbers, model names, and tool commands that no longer match the repo.
- Instructions for a framework, script, or directory that's since been removed.
- Cross-check build/test/lint commands against `package.json`, `Makefile`, `pyproject.toml`, or equivalent — a wrong test command is worse than none.

**Bloat and rent.**
- Anything derivable from the code itself (file tree listings, dependency lists, restating what a function does). Claude can read the repo.
