claude-prototype

Build production-feel HTML prototypes for sales demos, stakeholder reviews, and design exploration. Runs a discovery Q&A, scaffolds a zero-dep static site (HTML + Tailwind CDN + CSS variables + theme switcher + layout switcher + URL-state + feedback overlay + always-visible control bar), and runs a design-quality assessment loop. Use when the user says "prototype", "mockup", "demo", "pitch page", "sales demo", "click-through", or describes a UI they want to show someone without building the real thing. Also handles /prototype variant "<vibe>" (fork a variant) and /prototype apply-feedback <file> (apply pinned feedback JSON).
