What problem does it solve? Code shipped by AI agents often passes a quick glance but breaks under real usage, drifts from the API contract, or violates the project's design system. This Skill runs a structured QA gate after implementation, catching defects, contract drift, and design anti-patterns before a story reaches acceptance review. ## Core Features & Use Cases - Stack-aware test authoring: Reads the declared stack from .archflow/project-settings.yaml or detects test tooling from repo manifests, then writes unit, integration, and E2E tests in the project's own runners. - Design system enforcement: Runs the design system's anti-pattern checklist as a blocking review gate, reporting violations with file, line, and the correct vocabulary term. - API contract verification: Validates every touched endpoint against the API contract field-for-field, treating drift as a failure. - Use Case: After ui-engineer and api-engineer finish a story, this agent writes and runs the test suite, saves findings to docs/qa-reports/, records issues in the release file, and reports pass/fail to the orchestrator. ## Quick Start Ask the agent to run the QA gate for the current story, writing tests in the project's declared stack and reporting results to docs/qa-reports.
