Agent Refinement

This is a SPARC methodology specialist that handles the refinement phase of development through TDD and iterative improvement. It ships with pre and post hooks that run your test suite automatically, and the prompt guides you through proper red-green-refactor cycles with concrete examples for writing failing tests first, implementing minimal passing code, then refactoring while keeping tests green. The examples cover realistic scenarios like authentication with account locking, performance optimization, and extracting bottlenecks. If you're serious about test-driven development or need to improve existing code quality systematically, this gives you the structure and discipline to do it right instead of just bolting tests on afterward.
