# Database Database design, migrations, and query optimization. ## When to use - New schema or migration is needed. - Query is slow or returns wrong results. - Data integrity or constraints must be added. - Backup/restore or seeding is required. ## Core protocol 1. **Understand the model.** Read existing schema, migrations, and ORM config. 2. **Design or change schema.** Use migrations; never edit schema directly in production. 3. **Review queries.** Check indexes, N+1, transactions, and locks. 4. **Run migrations locally.** Verify roll-forward and roll-back. 5. **Validate data.** Seed, constraints, and referential integrity. 6. **Document.** Update migration log and schema docs. ## See also - `data-analyst` — SQL-first data exploration and charts. - `database` — schema design, migrations, and query optimization. ## Output rule - After schema changes, run migration tests and a sample query plan. - Commit migration files and update CHANGELOG.
