/review — Multi-Agent Code Review

Review changes on branch: $ARGUMENTS

1. Gather Context

git diff main...$ARGUMENTS --stat
git diff main...$ARGUMENTS
git log main...$ARGUMENTS --oneline

2. Launch Review Teammates

Spawn an Opus teammate for critical reviews and a Haiku teammate for structural checks. Max 2 active at once.

Opus teammate reviews (correctness + security):

• •Does the code match acceptance criteria? Edge cases handled?
• •Injection vulnerabilities? Auth/authz issues? Secrets in code?
• •Input validation on user-facing endpoints?
• •OWASP Top 10 violations?

Haiku teammate reviews (performance + maintainability):

• •N+1 queries? Unbounded loops/recursion? Memory leaks?
• •Clear naming? Single-responsibility functions?
• •Files under 500 lines? Tests present and meaningful?

3. Compile Results

APPROVE — No blocking issues. REQUEST CHANGES — List each blocking finding with file:line, what's wrong, how to fix it.

4. Post to GitHub PR

Check if a PR exists for the branch:

gh pr view $ARGUMENTS --json number,url --jq '.number' 2>/dev/null

If PR exists

Post review findings as a PR comment. Agents do NOT approve or request changes — only humans approve PRs. This is a security boundary.

If no blocking issues:

gh pr comment $ARGUMENTS --body "$(cat <<'EOF'
## Agent Review: APPROVED (advisory)

| Reviewer | Verdict | Findings |
| --- | --- | --- |
| Correctness + Security (Opus) | APPROVE | <summary> |
| Performance + Maintainability (Haiku) | APPROVE | <summary> |

No blocking issues found. **A human reviewer must still approve this PR.**

If blocking issues found:

gh pr comment $ARGUMENTS --body "$(cat <<'EOF'
## Agent Review: CHANGES REQUESTED (advisory)

### Blocking Issues
1. <file:line> — <what's wrong> — <how to fix>
2. ...

**These issues should be resolved before human approval.**

If no PR exists

Write findings to tasks/<task-id>/review.md as a fallback. Tell the user no PR was found to post to.
