# code-review-pro

Reviews files, a module, a diff or a branch and returns severity-ranked findings: vulnerabilities, correctness bugs, performance and maintainability issues, each with evidence and a fix.

## What it does

The skill runs review in stages. First it sets scope: a pasted snippet, specific files, the working-tree diff (`git diff`, `git diff --staged`), or a branch against its base (`git diff main...HEAD`). On a diff it reviews the changed lines but reads enough surrounding code to see how they are called.

Then it learns context: language, framework and version from `package.json`, `pyproject.toml`, `go.mod`; how the code is reached (HTTP handler, job, CLI, library); what input is untrusted; repo conventions. Review follows a fixed order — security, correctness and edge cases, performance, maintainability. Vulnerabilities are mapped to OWASP Top 10:2025.

Every candidate finding gets verified before it lands in the report: the skill traces the data flow, checks whether anything upstream already validates or escapes the input, and looks for a covering test. If it can run code, it reproduces the bug. Output is grouped as Critical, High, Medium, Low, with a verdict of Ship / Ship after fixes / Do not ship and a short "What is solid" section. The skill's own guidance is blunt: more than about 15 findings buries the critical ones, and every Fix block has to compile for the version in the repo. Posting line comments on a GitHub pull request is a different job — that is git-pr-reviewer.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill code-review-pro -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill code-review-pro -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install OneWave-AI/claude-skills code-review-pro
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill code-review-pro -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/OneWave-AI/claude-skills --path code-review-pro
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add OneWave-AI/claude-skills --skill code-review-pro -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/OneWave-AI/claude-skills/tree/HEAD/code-review-pro/SKILL.md

## When to use it
- catch a SQL injection in user search before shipping
- tell what is wrong with a branch diff before merge
- separate real bugs from linter noise
- check whether input is validated one layer up
- collect evidence and fixes into one severity-ranked report

## Example prompts
- Review this branch against main and rank the findings by severity
- Look at `git diff --staged` — any vulnerabilities or bugs in there?
- Audit `src/api/users.ts` for security and performance

description: Performs a deep code review of files, modules, a diff, or a branch - finding security vulnerabilities (mapped to OWASP Top 10:2025), correctness bugs, performance problems, and maintainability issues - and returns severity-ranked findings with evidence and concrete fixes. Use when the user asks to review, audit, or sanity-check code, asks "is this safe", "what's wrong with this", "find bugs", or wants a security or performance pass before shipping. For posting line comments on a GitHub pull request, use git-pr-reviewer.

# Code Review Pro

Find the problems that matter, prove each one, and show the fix. A short list of real issues beats a long list of maybes.

## Workflow

1. **Set the scope.** Decide what is under review: a pasted snippet, specific files, the working-tree diff (`git diff`, `git diff --staged`), or a branch against its base (`git diff main...HEAD`). For a diff, review the changed lines but read enough surrounding code to know how they are called.

2. **Learn the context before judging.** Identify language, framework and version (check `package.json`, `pyproject.toml`, `go.mod`, and so on), how the code is reached (HTTP handler, job, CLI, library), what input is untrusted, and any repo conventions (linters, `CLAUDE.md`, existing patterns). A pattern that is a bug in one framework can be safe in another; for example, React escapes JSX text, so XSS lives in `dangerouslySetInnerHTML`, `href` values, and raw HTML sinks.

3. **Review in priority order**, using [references/checklist.md](references/checklist.md):
   1. Security
   2. Correctness and edge cases
   3. Performance
   4. Maintainability and conventions

4. **Verify every finding before reporting it.** For each candidate, trace the data flow: where does the input come from, can an attacker or real user control it, and does anything upstream already validate or escape it? Check whether a test covers it. If you can run code, reproduce the bug with a small test or script. Drop findings you cannot support; mark the rest with a confidence level.

5. **Rank and write the report** in the format below. Lead with the highest severity. Group repeated instances of one problem into a single finding with all locations.
