test-first-development-loop

Coaches a strict test-first coding loop — shape each increment as one small failing test, add only enough implementation to turn it green, then improve the design while every check stays green, and repeat. Use when the user asks for test-driven development or red-green-refactor, when a feature should grow test by test, when a bug fix should begin with a reproducing failing test, or when untested legacy code needs a safety net before being changed. Not for choosing or installing test frameworks and runners, setting up CI pipelines, drafting manual QA plans, or reviewing code that already has coverage.
