TDD prevents implementation drift and untested changes by forcing you to prove each behavior with a failing test before writing production code.
Use case: You’re fixing a bug reported in a GitHub Issue—write a single reproducing test first, make the smallest change that passes, then refactor to keep the codebase deep and maintainable.
Use the tdd skill to produce one failing pytest test against the public interface, implement the minimal fix to make it pass, and then refactor the implementation while keeping the interface stable.

The red green refactor workflow requires writing exactly one failing pytest test against the public interface, implementing the minimal code to pass it, and then refactoring to hide complexity without changing the interface.
Test-driven development for bug fixing is needed when you want to prevent implementation drift by first writing a single reproducing pytest test, ensuring the unverified code change is proven before production code is modified.
Mocking boundaries in unit testing should be limited strictly to system boundaries like external APIs, databases, time, and filesystem, while avoiding mocking internal collaborators to maintain refactoring integrity.
Tracing acceptance criteria to pytest tests involves ensuring every single test maps directly to a Lean PRD testing decision or user story, keeping the scope aligned with the work being built during the red green refactor loop.
Test-driven development applies to refactoring by allowing you to hide implementation complexity and build deeper modules, strictly requiring that the public interface remains stable and does not grow.
