Purpose

Compatibility review for backwards/forwards compatibility across APIs, events, database, config, clients, and deployment versions.

Review focus

• backward incompatibility
• rolling deploy issue
• old client break
• database expand-contract violation
• event versioning gap

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.
