Rails Migration Patterns
Write Rails database migrations following project conventions: UUID primary keys with pgcrypto, named indexes, array columns, bulk mode, and proper column defaults. Use this skill whenever creating or modifying database tables, adding columns, creating indexes, or writing any ActiveRecord migration. Triggers on: 'create migration', 'add column', 'create table', 'add index', 'change column', 'database change', 'new migration', 'schema change', or any task that requires a db/migrate file.
