Does it generate migration scripts?

Absolutely. The skill generates reversible (up and down) migration scripts to help you evolve your schema while ensuring backward compatibility.

How does it handle performance optimization?

It analyzes your intended access patterns to suggest optimal indexing strategies, primary key choices, and selective denormalization for read-heavy workloads.

What database types does this skill support?

It supports both SQL (PostgreSQL, MySQL, etc.) and NoSQL (MongoDB, DynamoDB) design patterns, defaulting to SQL if not specified.

Can it help with existing database tables?

Yes, you can use commands like 'normalize {table}' or 'review schema' to audit, refactor, and improve existing database structures.

Does it enforce data integrity?

Yes, it prioritizes data integrity by automatically defining foreign key constraints, proper data types, and check constraints to prevent data corruption.
