Why use this instead of standard ORM documentation?

While ORMs generate basic SQL, this skill adds a safety layer by enforcing production-grade practices like creating indexes concurrently and separating data migrations from schema changes.

Which migration tools and ORMs are included?

It features specialized guidance for Prisma, Drizzle, Django's migration system, TypeORM, and golang-migrate, including custom SQL workarounds for ORM limitations.

How does this skill help prevent database downtime?

It implements the expand-contract pattern, which breaks schema changes into multi-stage deployments. This ensures the application remains compatible with the database at every step of the transition.

Does it support batch updates for large tables?

Yes, the skill provides specific patterns for PostgreSQL batch updates with progress tracking to avoid long-running transactions and table locks on tables with millions of rows.

Implements safe, zero-downtime database schema changes and data migrations across major SQL dialects and ORMs.

The Database Migrations skill provides a specialized framework for managing production database changes without risking data loss or system downtime. It equips Claude with industry-standard patterns for PostgreSQL and MySQL, emphasizing the 'expand-contract' strategy and safe DDL operations like concurrent index creation. By providing domain-specific guidance for popular tools such as Prisma, Drizzle, Django, and golang-migrate, this skill ensures that schema evolutions are reversible, immutable, and optimized for performance on production-scale datasets.
