Can it help identify performance bottlenecks?

Yes, the skill includes methods for performance testing that use EXPLAIN statements to verify index usage and ensure query execution times remain within acceptable limits.

What types of integrity checks are included?

It covers a wide range of checks including unique constraints, foreign key referential integrity, and domain-specific check constraints (e.g., age or status validations).

Does it support transaction isolation testing?

Absolutely. It provides code examples for testing concurrent transactions to ensure they remain isolated and maintain data consistency under load.

How does this skill help with database migrations?

It provides standardized patterns to verify that migrations apply correctly, are fully reversible via rollbacks, and do not cause data loss during the transition.
