# Review PR Review a pull request for bugs, regressions, missing tests, and risky changes. When explicitly invoked with extra text, treat that text as the PR number or URL. If no PR reference is provided, infer it from the current branch. ## Process 1. **Preferred execution** - If subagents are available, use `github-dev:pr-reviewer` and pass the PR reference. - Otherwise follow the manual steps below. 2. **Parse PR reference** - If a PR number or URL is provided, extract owner, repo, and PR number. - If not, auto-detect the PR from the current branch with `gh pr view --json number,headRefName`. 3. **Fetch PR data** - Use `gh pr diff <number>` for the full diff. - Use `gh pr view <number> --json files` for the changed file list. - Skip generated or vendored files such as `.lock`, `.min.js`, `.min.css`, `dist/`, `build/`, `vendor/`, `node_modules/`, `_pb2.py`, and images. 4. **Review focus** - Only report issues that require fixes. - Only review PR changes, never pre-existing issues in unchanged code. - Prioritize bugs, security issues, breaking changes, performance issues, edge cases, and missing tests. - Combine related issues that share the same root cause. - Keep the list short and high signal. 5. **Review comment rules** - Only create pending PR comments, never submit or confirm the review automatically. - Use `gh` for GitHub operations. - Start comments in lowercase, keep them short, avoid end punctuation when possible...
