Why does it require a rollback method for every change?

Reversibility is a core principle to ensure that any deployment issue can be quickly mitigated by rolling back the database state without manual data recovery.

What frameworks does this skill support?

It provides standardized patterns for popular frameworks including Alembic (Python), Rails (Ruby), and Sequelize (JavaScript), though the core principles apply to any migration tool.

How does it handle zero-downtime deployments?

The skill guides Claude to use multi-step strategies for destructive changes (like renaming or removing columns) and concurrent indexing to ensure the database remains available during updates.

Can it handle data migrations as well as schema changes?

Yes, it enforces the strict separation of schema and data migrations, emphasizing batch processing and idempotency to protect large production datasets.

Database Management

Enforces best practices for creating reversible, zero-downtime database schema evolutions and data migrations.

About

The Backend Migration Standards skill equips Claude with rigorous protocols for managing database evolution across various ecosystems like Alembic, Rails, and Sequelize. It ensures that every schema change is reversible, follows strict naming conventions, and implements zero-downtime strategies such as concurrent indexing and multi-step column removal. By prioritizing data integrity and deployment safety, this skill helps developers avoid common pitfalls like table locking, inconsistent versioning, or destructive changes in production environments.
