description

Create and manage database schema migrations with reversible changes, clear naming, and safe deployment practices. Use this skill when writing database migration files, modifying database schemas, creating migration scripts, or managing database version control. When working on migration files in database migration directories, files defining schema changes (CREATE TABLE, ALTER TABLE, DROP TABLE), migration rollback/down methods, database index creation scripts, seed data or data migration files, ORM migration configurations (Prisma, Drizzle, TypeORM), or files handling database versioning and migration history.
