What problem does it solve? Design questions about state models, business logic, or UI layouts are hard to answer on paper. This Skill builds throwaway, runnable prototypes that let you press buttons, flip between variants, and discover flaws in an idea before committing to production code. ## Core Features & Use Cases - Logic Prototypes: Build a lightweight terminal app with a pure reducer, state machine, or function set behind it, so you can drive state transitions by hand and watch edge cases unfold. - UI Prototypes: Generate 3-5 structurally different variants of a page on a single route, switchable via a ?variant= URL param and a floating bottom bar with arrow-key navigation. - Capture Workflow: Fold validated decisions into real code while preserving the full prototype on a throwaway branch as a primary source. - Use Case: Before writing a new onboarding flow, generate three radically different layouts on the existing settings route, flip through them in the browser, pick the winner, and discard the rest. ## Quick Start Ask the AI to build a throwaway prototype that tests whether your state machine handles a tricky edge case, or to generate three UI variants of a page switchable via a URL parameter.
