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.

Security & Testing

Validates database schemas, integrity constraints, and migration safety to prevent data loss and ensure system reliability.

About

The Database Testing skill provides specialized guidance for maintaining high-quality data persistence layers. It equips Claude with the patterns necessary to validate database structures, verify referential integrity, and ensure that migrations are both successful and reversible. By focusing on critical areas like transaction isolation and query performance through EXPLAIN plan analysis, this skill helps developers catch catastrophic data bugs and performance bottlenecks before they reach production environments.
