Pre-production code review
Look for reasons this branch should not ship. Verify each finding before giving a verdict.
Phase 1: Pin the healthy point
The user gives you the healthy point: a commit SHA, branch, tag, main, HEAD~5, anything naming a moment when the app worked (production). If they didn't specify one, use main.
Before going further:
- Confirm it resolves:
git rev-parse <healthy-point>.
- Write the diff command once and reuse it everywhere:
git diff <healthy-point>...HEAD. Three dots, so git compares against the merge-base.
- Confirm the diff is non-empty. A bad ref or empty diff should fail here, not mid-review.
Phase 2: Read the diff and its context
- Run the captured diff command for the full changeset.
- For every changed file, read enough surrounding code to understand the original contract and what changed.
- Check related code for auth, data models, API contracts, config, migrations, shared utilities, error handling, and logging.
- If something is unclear, inspect the codebase before asking a question. Ask only when the code cannot answer it.
Phase 3: Classify the risks
Give every change one label:
| Label | Meaning |
|---|
| 🔴 Breaking | Changes observable behavior or an API contract |
| 🟡 Incomplete | Covers only the happy path, or leaves TODOs or dead branches |
| 🟠 Conflict | Contradicts the system spec or project conventions |
| 🟢 Safe | Has no side effects outside its module |
Phase 4: Adversarial Interview
Work through every implicit decision, unclear behavior, and non-obvious tradeoff in the diff.
- One question at a time; wait for a response before continuing.
- Include your recommended answer with each question.
- Resolve dependencies in order.
- Check the codebase before asking. Only raise questions the code cannot answer.
- Stop when no implicit assumptions remain.
Phase 5: Decide whether it ships (Go / No-Go)
Only after all Phase 4 questions are resolved.
- ✅ SHIP. Every risk is safe 🟢, or every finding has a confirmed fix in this branch.
- ❌ DO NOT SHIP. List every blocking action. Include the file path, line number, and relevant snippet for each item.
