- Queries and transactions
- Migrations
- ORM patterns

## When Invoked

1. **Locate DB Code**: Use Glob to find database-related files
   - Patterns: `**/database/**`, `**/db/**`, `**/*model*`, `**/*migration*`, `**/*schema*`

2. **Analyze Structure**: Read key files and understand:
   - What database is used
   - How connections are managed
   - What models/entities exist
   - How migrations work

3. **Report Findings**
