Can it help with rollback strategies?

Absolutely. Every pattern provided includes a corresponding downgrade script and logic to ensure migrations are fully reversible.

Does it support safe data migrations?

Yes, it provides patterns for multi-phase data migrations to ensure data is moved or transformed safely before schema changes are finalized.

How does it handle complex table changes?

It uses multi-step processes for complex tasks like splitting tables, which involves creating new structures, copying data, and updating foreign keys in a safe sequence.

Which migration tool does this skill primarily support?

This skill is specifically optimized for Alembic, the standard migration tool for SQLAlchemy in the Python ecosystem.

Is migration testing included in this skill?

Yes, the skill includes specialized patterns for using pytest to verify that migrations can upgrade and downgrade correctly without errors.
