TDD implementation skill — takes existing tests and incrementally implements code to make them pass. Tests are treated as the specification and must not be modified unless they misrepresent the intended behavior. Use this skill when the user has tests written (by tdd-spec or manually) and wants to implement the code, when the user says "make these tests pass", "implement this", "green phase", "write the implementation for these tests", or when there are failing tests that need implementation. Also trigger when the user has a test file open and asks to write the corresponding source code.

TDD-style test-first development skill. Generates comprehensive test cases that serve as executable specifications before any implementation code is written. Use this skill whenever the user asks to write tests first, create test cases, do TDD, write specs as tests, or mentions "test-driven". Also trigger when the user says things like "add tests for this feature", "what should the tests look like", "spec out the behavior", or wants to define expected behavior before coding. Even if the user just describes a feature or function they want to build, suggest using this skill to define the spec as tests first.
