safe-migrations
safe-migrations is a Databases & SQL skill for AI agents, published by sandeepmvl in the rails-skills repository on GitHub. Skillspace rates safe-migrations C (74/100) and it passed the safety scan; the rating is based on static analysis only.
Write zero-downtime database migrations for Ruby on Rails — strong_migrations rules, the add-column / set-default / backfill / enforce-NOT-NULL multi-deploy split, disable_ddl_transaction!, concurrent index creation on PostgreSQL, find_each batching, why change_column is dangerous, the deploy/migrate/deploy sequencing. Use when writing or reviewing Rails migrations, adding a column to a large table, removing or renaming columns, adding NOT NULL or foreign keys, adding indexes on big tables, when the user mentions strong_migrations, zero downtime, migration locks, deploy ordering, or asks how to backfill a column safely.
