What problem does it solve? Static mockups and screenshot-linked demos cannot test real user flows. This Skill builds working interactive prototypes with genuine clicks, inputs, validation, success and failure states, so teams can validate a flow before committing to production code. ## Core Features & Use Cases - Full Flow Wiring: Connects navigation, form validation, loading states, success/error feedback, and state changes across every screen, not just the happy path. - Structured Build Process: Follows a phased workflow from discovery and screen/state planning through per-screen construction, interaction wiring, persistence, and verification. - Responsive & Keyboard Verification: Walks the complete flow in preview to confirm tab navigation, Enter submission, Escape dismissal, and visible focus states. - Use Case: A designer needs a clickable onboarding demo with email validation, profile upload, and a success screen. The Skill produces a single self-contained HTML/CSS/JavaScript prototype with inline errors, simulated async loading, and keyboard support. ## Quick Start Ask the agent to make an interactive prototype of your onboarding flow with email validation, loading states, and keyboard navigation.
