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]"
• "Add column to [table]"
• "Rename [table/column]"
