## What it does

The skill hands the goal, commit identifiers, and diff to a subagent within the current runtime. It evaluates functional correctness first. Minor formatting quibbles and unprompted style suggestions are silenced to avoid wasting developer attention. Policy changes are checked against the base branch.

Verification requires strict evidence. A passing test only counts if it actively reproduces the failure beforehand, enforcing a red-before and green-after pattern. Scratch reproduction scripts and generated test receipts must not be committed to Git. The process stays strictly read-only until repairs are authorized.

High-risk tasks involving security or concurrency trigger an adversarial protocol. This mode demands executable checks and counterevidence before merging. The main branch strategy is direct. Changes stack forward in `main` without reverting.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add manaflow-ai/cmux --skill cmux-review -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add manaflow-ai/cmux --skill cmux-review -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add manaflow-ai/cmux --skill cmux-review -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install manaflow-ai/cmux cmux-review
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add manaflow-ai/cmux --skill cmux-review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/manaflow-ai/cmux --path skills/cmux-review
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add manaflow-ai/cmux --skill cmux-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/manaflow-ai/cmux/tree/HEAD/skills/cmux-review/SKILL.md

## When to use it
- catch logic defects in agent-written diffs before merge
- suppress subjective comments about formatting and code style
- verify bug fixes with red-before and green-after tests
- audit security and concurrency risks under an adversarial protocol

## Example prompts
- Run a pre-merge review on the latest commit diff
- Execute an adversarial review on the concurrency changes in storage
- Verify this bug fix with an independent subagent
