How does the code-quality skill improve AI-generated code?

It provides Claude with a rigorous set of constraints based on SOLID, DRY, and KISS principles, ensuring that generated code is modular, readable, and easy to maintain rather than just functional.

Does it support modern testing frameworks?

While language-agnostic in principle, it provides specific strategies for unit, integration, and E2E testing, focusing on testing behavior rather than implementation details.

What is included in the code review checklist?

The checklist covers five critical areas: Correctness, Security (input validation/secrets), Performance (N+1 queries/caching), Maintainability, and Testing coverage.

Can this skill help reduce technical debt?

Yes, it includes a directory of 'code smells' and specific refactoring techniques, allowing the agent to identify and fix issues like long methods, duplicate code, and deep nesting.
