?variant= URL param and a floating bottom bar with arrow-key cycling. - Capture Workflow: Fold validated decisions into real code while committing the prototype itself to a throwaway branch as a primary source. - Use Case: Before writing a checkout flow, prototype the state machine in a terminal TUI to confirm that cancel-after-payment transitions 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.High-intent search queries and answers about installing and using this skill.
Build a small interactive terminal app around a pure reducer or state machine, with keyboard shortcuts dispatching actions and the full state re-rendered after every keystroke. Keep the logic module free of I/O so it can be lifted into the real codebase once validated.
Render each variant on the same existing route gated by a ?variant= URL search param, with a floating bottom bar offering previous/next arrows and arrow-key cycling. Variants must differ structurally in layout and information hierarchy, not just color or copy.
No. A prototype that needs tests is no longer a prototype. Skip tests, persistence, and abstractions; include only the minimal error handling needed to keep it runnable, since the goal is to learn something fast and throw the code away.
Use a terminal (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 should look like, generating several variants on an existing route.
Fold the validated decision into the real code, then commit the full prototype to a throwaway branch kept out of main as a primary source. Leave a pointer to that branch on the implementation issue along with the verdict.
