/do-migrateInteractively manages Cloudflare Durable Objects migrations: create new classes, rename, delete, or transfer with validation, auto-tagging, and config backup.
/migrationGenerates timestamped up/down migration files for PostgreSQL, MySQL, SQLite, MongoDB using SQL or ORM, with run instructions and testing guidance.
/myco-anamorphDrafts canon schema migration to <new-version> via anamorph subagent: partial upgraders, tests, schema delta, migration guide. Requires governing craft path; stops before _canon.yaml update.
/d1-migrationManages Cloudflare D1 migrations: generate from schema changes, apply pending (local/remote), fix stuck ones, or check status.
/create-migrationGenerates up/down database migration files for schema changes using detected tool (Prisma, Django, Rails, etc.). Adds constraints, indexes, data logic; validates, saves to migrations dir, previews SQL.
