What problem does it solve?
Unsafe database migrations can cause downtime, data loss, and lock contention in production Rails or Sequel applications. This Skill helps developers write migrations that avoid these risks.
Core Features & Use Cases
- Iron Laws that define safe migration practices such as never dropping columns used by code and never adding defaults on large tables.
- Three‑step deployment process for adding, backfilling, and removing schema changes without downtime.
- Pattern libraries for adding columns, indexes, foreign keys, renames, type changes, and backfills with batch processing.
- Checklists and anti‑patterns to ensure reversibility and safety before committing.
- Reference guides for PostgreSQL, MySQL, SQLite, and Sequel migration syntax.
Quick Start
Ask the safe‑migrations skill to review a migration file and receive zero‑downtime recommendations.
