?variant= URL param and a floating bottom bar with arrow-key navigation. - Capture workflow: Fold validated decisions into real code while preserving the prototype on a throwaway branch as a primary source. - Use Case: You are unsure whether a membership invitation state machine handles revocation after acceptance. Build a logic prototype, hand the HTML file to a PM, and watch them discover the illegal transition in minutes. ## Quick Start Ask the AI to build a prototype that answers whether your state model handles a specific edge case, or to generate three UI variants of an existing page.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 in one script block, free-play buttons for each action, and tabbed guided walkthroughs for edge cases. Anyone can open it by double-clicking, with no framework, bundler, or server required.
Render 3 to 5 structurally different variant components on the existing route, gated by a ?variant= URL search param, with a floating bottom bar to cycle between them. Keep the existing data fetching and auth intact so variants are judged against real content.
Use a logic prototype when the question is whether a state model or data shape feels right under real cases. Use a UI prototype when the question is what a page should look like, since the two branches produce very different artifacts.
No. Prototypes skip tests, error handling, and persistence by default; state lives in memory. If the question explicitly involves a database, use a scratch database or local file clearly marked as disposable.
Fold the validated decision into the real codebase, then commit the full prototype to a throwaway branch as a primary source with a pointer on the implementation issue. The main branch keeps only the validated decision, not the prototype shell.
