Purpose

Regression-risk review for behavior changes likely to break existing users, flows, integrations, or production data.

Review focus

• changed fallback
• deleted branch
• changed default
• changed validation
• changed ordering
• changed error handling

Method

1. Inspect changed files and diff hunks relevant to this skill.
2. Use repository-native tools when available.
3. Prefer exact evidence from changed code.
4. Emit findings using the shared JSONL finding contract.
5. Avoid style-only comments unless they create maintainability or correctness risk.

Tooling hints

• Use grep or editor search before opening files.
• Use git, grep, and gh CLI. These are universally available and sufficient for all review tasks.
• Do not depend on tools beyond git, grep, cat, head, wc, and gh.
