Database change

Use this skill for database or persistence work. Treat production data as high-risk.

Workflow

1. Inspect current schema, migrations, models, queries, and database commands.
2. Prefer additive, backwards-compatible changes.
3. Consider existing production data and rollback path.
4. Keep migrations small and explicit.
5. Add persistence tests when behavior changes.
6. Document manual deploy or migration steps.
