What problem does it solve? Design questions about state models, business logic, or UI layouts are hard to settle on paper. This Skill builds a small throwaway prototype so you can press buttons, flip between variants, and discover flaws in the idea before committing to real code. ## Core Features & Use Cases - Logic Prototypes: Creates a lightweight interactive terminal app that drives a pure reducer, state machine, or function set through edge cases, re-rendering full state after every keystroke. - UI Prototypes: Generates 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 cycling. - Capture Workflow: Folds validated decisions into real code and preserves the prototype on a throwaway branch as a primary source, keeping main clean. - Use Case: Before building a checkout flow, prototype the state machine in a terminal TUI to confirm edge cases like "cancel after payment" behave correctly, then lift the validated reducer into the real module. ## Quick Start Ask the AI to build a throwaway prototype that answers whether your state model handles a specific edge case, or to generate three UI variants of a page switchable via a URL parameter.
