+# Review PR Command
+
+Review a PR against [CONTRIBUTING.md](../../CONTRIBUTING.md) acceptance criteria.
+
+## Usage
+
+```
+/review-pr <pr-url>
+```
+
+## Instructions
+
+1. Read [CONTRIBUTING.md](../../CONTRIBUTING.md) for current review criteria
+2. Extract PR number from argument (supports full URL or just number)
+3. Fetch PR details: `gh pr view <number> --repo vinta/awesome-python --json title,body,author,files,url`
+4. Fetch PR diff: `gh pr diff <number> --repo vinta/awesome-python`
+5. For each project added, fetch repo stats: `gh api repos/<owner>/<repo> --jq '{stars: .stargazers_count, created: .created_at, updated: .pushed_at, language: .language, archived: .archived}'`
+6. Review against all criteria in CONTRIBUTING.md
+
+## Quick Rejection Checks
+
+Check these rules first - if any fail, recommend rejection:
+
+- Add more than one project per PR
+- Duplicate of existing entry
+- Self-promotion (wait for someone else to find it useful and submit)
+- Less than 100 GitHub stars AND not justified as a hidden gem
+- Project is archived or abandoned (no commits in 12+ months)
+- No documentation or unclear use case
+
+## Output Format
+
+Provide a simple review:
+
+1. **Rejection Check** - table with the 3 rules and PASS/FAIL
+2. **Recommendation** - APPROVE for further review, or REJECT with reason
+
+## Closing PRs
+
+If user asks to close/reject:
+
+```bash
+gh pr close <number> --repo vinta/awesome-python --comment "<brief reason>"
+```
+
+Keep rejection comments short and reference CONTRIBUTING.md.
