migration
migration is a Databases & SQL skill for AI agents, published by igmarin in the rails-agent-skills repository on GitHub. Skillspace rates migration D (66/100) and it passed the safety scan; the rating is based on static analysis only.
Orchestrates safe database migration with hard gates: plan migration assessing lock behavior, rollback strategy, and performance impact with EXPLAIN → use expand-contract for column changes (add nullable→backfill→enforce NOT NULL), never combine schema change and data backfill in one migration → test idempotent migrate/rollback/re-migrate cycle and full suite in development → verify on staging with production-like data → deploy to production with monitoring and rollback readiness; phases planning→development testing→staging→production. Use when adding columns, creating tables, modifying indexes, or any database schema changes. Trigger: database migration, schema change, add column, create table, modify index, rails migration.
