# Database Migration Generator

Generate database migrations with rollback capability for schema changes, with built-in ToM verification for safe database operations.

> **Implementation note**: This skill uses direct `Write()` calls with inline templates (see Steps 3–4 and "Schema Change Templates" section below). Unlike `frontend-component` and `backend-endpoint`, there are no Python helper functions — the skill is prose-driven by design, since migration generation is highly schema-specific and benefits from inline framework templates. Future work (tracked for v6.6.0) may extract a timestamp generator and per-framework templates.

## When to Invoke

Auto-invoke when user mentions:
- "Create migration"
- "Add table"
- "Modify schema"
- "Change database"
- "Database migration for [change]"
