?variant= URL param and a floating bottom bar with arrow-key navigation. - Capture Workflow: Fold validated decisions into real code and preserve the prototype on a throwaway branch as a primary source. - Use Case: A PM is unsure whether a state machine handles an edge case. You build a shareable HTML demo in domain language; they click through scenarios, spot the illegal transition, and you fix the model before writing production code. ## Quick Start Use the prototype skill to build a clickable demo that tests whether my order state machine handles cancellation after shipping.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 tabbed guided walkthroughs. Anyone can open it by double-clicking and push the model through edge cases without installing anything.
Render several 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 and only swap the rendered subtree per variant.
Use a logic prototype when the question is whether a state model or data shape behaves correctly under real cases. Use a UI prototype when the question is what a page should look like, comparing radically different layouts side by side.
Yes. The logic prototype is one HTML file with no framework, bundler, or server, written in domain language rather than code terms. A designer, PM, or domain expert can open it and drive the scenarios themselves.
Prototypes skip tests, error handling, persistence, and polish by design, so they must never ship directly to production. Once a question is answered, fold the validated decision into real code and move the prototype to a throwaway branch.
