?variant= URL param and a floating bottom bar with arrow-key cycling, mounted inside an existing page when possible. - Capture Workflow: Fold validated decisions into real code and preserve the prototype on a throwaway branch as a primary source, keeping main clean. - Use Case: A product manager is unsure whether an order state machine handles cancellation-after-payment. The Skill builds a one-file HTML demo with scenario walkthroughs so the PM can click through the edge case and confirm the model. ## Quick Start Ask the AI to build a throwaway prototype that answers whether your state model or page layout feels right, and specify whether the question is about logic or UI.High-intent search queries and answers about installing and using this skill.
Build a single self-contained HTML file with a pure reducer or state machine module, free-play action buttons, and guided scenario walkthroughs. Anyone can open it by double-clicking and push the model through edge cases without installing anything.
Render 3-5 structurally different variants on the same route, gated by a ?variant= URL search param, with a floating bottom bar to cycle between them. Keep existing data fetching intact so variants are judged against real content.
Use a logic prototype when the question is whether a state model or data shape behaves correctly under edge cases. Use a UI prototype when the question is what a page or component should look like. The two produce very different artifacts.
No. A prototype is throwaway code that answers one question fast, so tests, abstractions, and polish are explicitly skipped. Once the question is answered, rewrite the validated decision properly in the real codebase.
Fold the validated decision into the real code on main, then commit the full prototype to a throwaway branch as a primary source with a pointer on the implementation issue. Prototype code left in main rots and confuses later readers.
