Review PR
Run the ralph.reviewer.yml orchestration loop against a pull request. The loop checks out the PR in an isolated worktree, runs tests, reviews the diff, and produces a structured report.
Usage
/review-pr <PR number or URL>
Accepts: 207, #207, or https://github.com/.../pull/207
Execution
1. Parse the PR argument
Extract the PR number from the argument. Strip # prefix or extract from URL path.
2. Run the reviewer loop
ralph run -H ralph.reviewer.yml -p "Review PR #<N>"
Bash tool settings:
timeout: 600000 (10 minutes)run_in_background: true
Use TaskOutput with block: true to wait for completion.
3. Display the report
Read and print .ralph/REVIEW-REPORT.md to the conversation.
If the report file doesn't exist (loop failed before the synthesizer hat), check for and display whatever intermediate files exist:
.ralph/review-scope.md — what was scoped.ralph/review-verification.md — test results.ralph/review-findings.md — review findings
4. Verify cleanup
Check that the review worktree was removed:
ls -d .worktrees/review-<N> 2>/dev/null
- If gone: cleanup succeeded, no action needed.
- If still present: warn the user but do NOT force-remove. Say what's there and let them decide.
Also note the presence of intermediate files (.ralph/review-scope.md, etc.) — they're useful for debugging but the user may want to clean them up later.
Error Handling
| Situation | Action |
|---|
| Ralph exits non-zero | Display error output. Suggest re-running with RALPH_DIAGNOSTICS=1 |
| Report file missing | Display intermediate files that do exist (scope, verification, findings) |
| PR argument missing | Ask the user for the PR number |
| PR argument unparseable | Ask the user to provide a bare number, #N, or full GitHub URL |
What This Skill Does NOT Do
- Does NOT validate the PR exists (the scoper hat handles that)
- Does NOT modify any source code (read-only review)
- Does NOT post comments to GitHub
- Does NOT own worktree cleanup (verifies only)
- Does NOT enable diagnostics by default
