Build features with tests that survive refactors.
Guides feature development and bug fixes through one behavior-focused test and implementation cycle at a time.
When to use it
Use when the user requests TDD, red-green-refactor, integration tests, or test-first development for features or bug fixes.
It changes how the agent develops project code by agreeing on interfaces and test priorities with the user before applying test-first development.
