You describe an idea, it interviews you, researches the market, generates a PRD for your approval, then autonomously builds a complete Expo React Native app with QA checks at each step. ASO materials, marketing copy, and fastlane deploy config included.

Four modes: interactive build from an idea, headless build from a PRD (for other agents to call), improve an existing app, and release via fastlane + Maestro screenshots.

The headless mode is the interesting bit — it accepts a formal PRD schema, so an upstream agent can generate specs and feed them in. No human in the loop.
