What problem does it solve? Teams practicing acceptance test-driven development need failing test scaffolds written before implementation begins, but manually mapping acceptance criteria to E2E, API, and component tests is slow and inconsistent. ## Core Features & Use Cases - Red-Phase Test Generation: Creates E2E, API, and component test scaffolds marked with test.skip() that fail until implementation exists. - Test Strategy Mapping: Converts story acceptance criteria into prioritized (P0-P3) scenarios at the appropriate test level based on detected stack (frontend, backend, fullstack). - Supporting Infrastructure: Produces data factories with faker, fixtures with auto-cleanup, mock requirements, and data-testid lists for the dev team. - Use Case: Given an approved user story for a registration feature, generate Playwright API and E2E scaffolds plus an ATDD checklist that hands the dev team a red-green-refactor implementation roadmap. ## Quick Start Ask the agent to run the ATDD workflow for your approved story file to generate red-phase acceptance test scaffolds and an implementation checklist.
