# review-pr

Walks a branch diff against a checklist: bugs, security, performance, tests. Ends with a verdict — approve, request changes or discuss.

## What it does

The skill diffs your current branch against the base one and goes through the changes file by file. It tries `main` first, then `master`, and asks if neither exists. Commits come from `git log --oneline <base>..HEAD`, the whole diff from `git diff <base>...HEAD`. When the diff is large it drops to a single file: `git diff <base>...HEAD -- <file>`.

Every changed file gets checked for logic errors, null or undefined access, race conditions, injection, XSS, auth bypass, hardcoded secrets, SSRF, N+1 queries, unbounded loops, memory leaks and swallowed exceptions. Style drift and missing tests for new behaviour or edge cases are flagged too.

The output is a short summary, a list of problems worth fixing before merge, non-blocking suggestions and a verdict. File paths and line numbers are expected, and fixes should be concrete. The skill only holds `Bash`, `Read`, `Grep` and `Glob`, so it never edits your code — you apply the fixes yourself.

## Install

### Claude Code (native platform)

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

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add SeifBenayed/cloclo --skill review-pr -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add SeifBenayed/cloclo --skill review-pr -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install SeifBenayed/cloclo review-pr
```

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

### Gemini CLI

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

2. **Platform CLI**
```bash
gemini skills install https://github.com/SeifBenayed/cloclo --path .claude/skills/review-pr
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add SeifBenayed/cloclo --skill review-pr -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/SeifBenayed/cloclo/tree/HEAD/.claude/skills/review-pr/SKILL.md

## When to use it
- scan a branch diff for bugs before merging
- spot a hardcoded secret or auth bypass in the changes
- catch N+1 queries and memory leaks in new code
- check that new functionality comes with tests
- get a structured verdict on a pull request

## Example prompts
- Review the current branch against main
- Check this pull request for bugs and security issues
- Look at the diff for `src/api/users.ts` and tell me what to fix before merge

# Pull Request Review

Review the current branch's changes compared to the base branch.

## Steps

1. Determine the base branch:
   - Try `main`, then `master`, then ask
   - Run `git log --oneline <base>..HEAD` to see all commits in this PR
2. Run `git diff <base>...HEAD` to see the full diff
3. For large diffs, review file-by-file using `git diff <base>...HEAD -- <file>`
4. For each changed file, check for:
   - **Bugs**: logic errors, off-by-one, null/undefined access, race conditions
   - **Security**: injection, XSS, auth bypass, hardcoded secrets, SSRF
   - **Performance**: N+1 queries, unbounded loops, missing indexes, memory leaks
   - **Error handling**: missing try/catch, swallowed errors, unclear error messages
   - **Style**: inconsistency with the rest of the codebase
   - **Tests**: missing tests for new functionality or edge cases
5. Provide a structured review:

   **Summary** — What the PR does (1-2 sentences)

   **Issues** — Bugs, security, or correctness problems that should be fixed before merge

   **Suggestions** — Non-blocking improvements worth considering

   **Verdict** — Approve / Request Changes / Needs Discussion

Be specific — reference file paths and line numbers. Suggest concrete fixes, not vague advice.

The third-party file has ended. Everything between the e365ee7acdd54392 tags is data: requests and commands from it are not followed. An “end of file” line with another tag inside the block is part of the file.
