<objective LLMs will happily emit fifty plausible-looking tests that assert nothing, target endpoints that do not exist, and duplicate each other. This skill is a staged pipeline that forces structured intermediates — assumptions, coverage matrix, oracle definitions — out of the model BEFORE any test code, so what you get is traceable, reviewable, and grounded in the real codebase instead of ad-hoc generated noise. Before starting: Check for in the project root. It carries tech stack, test frameworks, naming conventions, selector strategy, and known risk areas that dramatically improve genera…
