What problem does it solve? Design questions about business logic or UI layout are hard to answer on paper. This Skill builds throwaway prototypes that let you push a state model through real cases in a terminal, or flip between radically different UI variants in the browser, so you can feel what works before committing to production code. ## Core Features & Use Cases - Logic Prototypes: Build a lightweight interactive TUI around a pure reducer, state machine, or function set to test edge cases in your state model by hand. - UI Prototypes: Generate 3-5 structurally different variants of a page on an existing route, switchable via a ?variant= URL param and a floating bottom bar with arrow-key navigation. - Clean Capture Workflow: Fold validated decisions into real code while preserving the full prototype on a throwaway branch as a primary source. - Use Case: You're unsure whether your state machine handles a specific edge case. The Skill builds a one-command terminal app where you press keys to dispatch actions and watch the full state re-render after each step, exposing the flaw in minutes. ## Quick Start Ask the AI to build a throwaway prototype that tests whether your state model handles a specific edge case, or to generate three UI variants of a page switchable via a URL parameter.
