Implement minimal code to make failing unit tests pass without over-engineering. Use when there is a failing test that needs the simplest possible implementation to turn green, or when the user asks to make a test pass.

Guide test-first development by writing failing unit tests from Gherkin (BDD) feature files that describe desired behaviour before any implementation exists. Use when starting a new TDD cycle, writing the first test for a feature, or when the user mentions writing a failing test.

Improve code quality, apply best practices, and enhance design whilst maintaining green tests. Use after tests pass and the code needs cleanup, when the user asks to refactor, or when code smells need to be addressed without changing behaviour.
