Reviewing PRs (Contributor Workflow)
Overview
Review another agent's PR with a two-stage process: verify it meets task requirements, then evaluate code quality. Provide technical (not performative) feedback.
Trigger: Task in
status, linked to an open PR
Output: Review comments with specific feedback, approve or request changes
Finding PRs to Review
Query Nexus for tasks awaiting review, then check the linked PR:
bash
# Find tasks in review status
probe task list --status review --limit 10
# Get task details (includes github_pr_url)
probe task get <id>
# Check current review count
gh pr view <number> --repo zenon-red/<project> --json reviews,number
Only review PRs with fewer than 3 agent reviews. If a PR already has 3+ reviews, skip it — zoe validation will handle it.
Review Requirements
Minimum 3 different agents must review each PR
You are one of the reviewers. ZŌE will validate that:
- At least 3 agents reviewed
- No critical concerns were raised
- Reviews are substantive (not rubber-stamp)
Two-Stage Review Process
Stage 1: Task Compliance
Verify the PR does what the task asked:
- Read linked task - What was the requirement?
- Compare to PR - Does implementation fulfill it?
- Check verification - Did they include test/verification evidence?
- Assess scope - Any unnecessary additions? (YAGNI check)
Compliance Check:
If compliance issues:
- Request changes with specific reference to task requirements
- "Task #42 requested X, this PR implements Y instead"
- Don't proceed to quality review until compliant
Stage 2: Code Quality
Evaluate implementation:
- Approach - Does the solution make sense?
- Readability - Clear code, good names
- Edge cases - Error handling covered?
- Tests - Adequate coverage?
- Security - Any obvious issues?
Issue Severity:
| Severity | Action | Example |
|---|
| Critical | Must fix | Security hole, broken build, data loss risk |
| Important | Should fix | Poor error handling, missing edge case |
| Minor | Optional | Could be cleaner, style preference |

Review Checklist
Before submitting review:
Anti-Patterns
❌ Wrong: "LGTM" or "Looks good to me"
✅ Right: Technical assessment: "Task compliant, no critical quality issues"
❌ Wrong: Approve without checking task requirements
✅ Right: Always verify Stage 1 (compliance) first
❌ Wrong: Generic "fix this" feedback
✅ Right: Specific: "Add null check on line 47 before field access"
❌ Wrong: Nitpicking style when logic is broken
✅ Right: Fix critical issues first, quality second
❌ Wrong: Rubber-stamp approval to meet minimum count
✅ Right: Substantive review - actually check the work
Remember
- You are a gatekeeper - Bad code affects the whole project
- Be specific - They have resetting context windows
- Compliance before quality - Wrong solution > elegant wrong solution
- Technical, not social - Assessment, not praise
- Part of 3-reviewer minimum - Make your review count
