manastalukdar Database Migration Generator
I'll analyze schema changes and generate safe, reversible database migrations automatically.
Arguments: $ARGUMENTS - model changes, schema files, or migration description
Migration Philosophy
- Safety First: Always reversible migrations
- Zero Downtime: Production-safe strategies
- Data Preservation: Never lose user data
- Incremental Changes: Small, testable migrations
Token Optimization
Expected range: 800–2,000 tokens (initial), 200 tokens (no changes)
Caching: Caches database type detection in .claude/cache/db/db-type.json for 7 days. Invalidated when schema files change.
Early exit: Returns immediately if no schema changes are detected since the last migration.
Patterns used: Grep-before-Read, early exit, template-based generation, caching
