Turn a product idea, PRD, or existing codebase into a complete, buildable wireframe package - a screen inventory, low-fi HTML wireframes, a machine-readable screens.json contract, and a spec doc that a coding agent can build from 1:1. Use whenever someone asks to wireframe an app, mock up screens, plan a UI before building, produce a design spec for an AI to implement, or turn a feature request into screens. Also use before writing UI code for a feature that spans more than one screen.
