What problem does it solve? When an idea is too vague for a written spec, this Skill builds a quick throwaway working version so you can see and feel the concept before committing to a full engineering pipeline. ## Core Features & Use Cases - Rapid Prototyping: Builds a minimal runnable artifact with hardcoded data and no tests, landing it in a gitignored prototypes/ directory. - Iteration Loop: Supports unlimited zero-ceremony rebuild rounds until the concept converges, tracked in PROTOTYPE.md and a prototypes log. - Convert to Spec: Promotes a converged prototype into the feature pipeline by seeding feature intake, reverse-engineering acceptance criteria from the artifact, and setting a size-based disposition (in-place vs rebuild). - Use Case: You have an idea for a dashboard widget but cannot describe its behavior in words. Run the prototype command, get a runnable rough cut in minutes, iterate twice, then promote it into a fully specced feature. ## Quick Start Ask the agent to prototype your idea, for example by saying "prototype a quick version of the export dialog so I can see how it feels".
