## What it does

review-swarm assigns a change to four sub-agents: intent and regression, security and privacy, performance and reliability, plus contracts and coverage. Each reviewer is read-only and returns concise findings rather than changing the workspace.

The skill can inspect named paths, current git changes, or a requested branch, commit, or PR comparison. It reads local guidance such as `AGENTS.md` before reviewing the touched area. For working-tree changes it uses `git diff`; staged changes use `git diff --cached`.

The main agent merges reports, removes duplicates and weak claims, then orders remaining issues by severity and confidence. It does not apply fixes, so expect a prioritised review and follow-up path rather than a patch.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill review-swarm -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add Dimillian/Skills --skill review-swarm -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install Dimillian/Skills review-swarm
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/Dimillian/Skills --path review-swarm
```

### Windsurf (Devin Desktop)

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

### OpenCode

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

## When to use it
- review a current git diff for behavioural regressions
- detect weakened access checks and sensitive-data exposure
- spot redundant I/O and fragile failure handling
- check API, schema, type, and configuration contracts
- prioritise fixes before merge

## Example prompts
- Run a parallel review of the current git diff and report material issues only.
- Review `src/auth` for security risks, regressions, and missing tests without editing files.
- Compare the requested branches and give me a prioritised path to fix issues before merge.

# Review Swarm

Review a diff with four read-only sub-agents in parallel, then have the main agent filter, order, and summarize only the issues that matter. This skill is review-only: sub-agents do not edit files, and the main agent does not apply fixes as part of this workflow.

## Step 1: Determine Scope and Intent

Prefer this scope order:

1. Files or paths explicitly named by the user
2. Current git changes
3. An explicit branch, commit, or PR diff requested by the user
4. Most recently modified tracked files, only if the user asked for a review and there is no clearer diff

If there is no clear review scope, stop and say so briefly.

When using git changes, choose the smallest correct diff command:

- unstaged work: `git diff`
- staged work: `git diff --cached`
- mixed staged and unstaged work: review both
- explicit branch or commit comparison: use exactly what the user requested

Before launching reviewers, read the closest local instructions and any relevant project docs for the touched area, such as:

- `AGENTS.md`
- repo workflow docs
- architecture or contract docs for the touched module

Build a short intent packet for the reviewers:

1. What behavior is meant to change
2. What behavior should remain unchanged
3. Any stated or inferred constraints, such as compatibility, rollout, security, or migration expectations

If the user did not state the intent clearly, infer it from the diff and say that the inference may be incomplete.

## Step 2: Launch Four Read-Only Reviewers in Parallel

Launch four sub-agents when the scope is large enough for parallel review to help. For a tiny diff or one very small file, it is acceptable to review locally instead.

For every sub-agent:

- give the same scope and the same intent packet
- state that the sub-agent is read-only
- do not let the sub-agent edit files, run `apply_patch`, stage changes, commit, or perform any other state-mutating action
- ask for concise findings only
- ask for: file and line or symbol, issue, why it matters, recommended follow-up, and confidence
- tell the sub-agent to avoid nits, style preferences, and speculative concerns without concrete impact
- tell the sub-agent to send findings back to the main agent only

Use these four review roles.

### Sub-Agent 1: Intent and Regression Review

Review whether the diff matches the intended behavior change without introducing extra behavior drift.

Check for:

1. Unintended behavior changes outside the stated scope
2. Broken edge cases or fallback paths
3. Contract drift between callers and callees
