Features and purpose

Create and manage database migrations following best practices for reversibility, zero-downtime deployments, and safe schema changes. Use this skill when creating new database migrations, writing migration up/down methods, implementing schema changes (adding/removing tables, columns, indexes, constraints), performing data migrations or transformations, refactoring database structure, implementing backwards-compatible migrations, creating indexes on large tables, renaming database objects, or working with migration files in directories like migrations/, db/migrate/, alembic/versions/, or similar. Use when working with ORMs like Sequelize, TypeORM, Prisma, SQLAlchemy, ActiveRecord, Django ORM, or raw SQL migration files.
