Build a runnable, multi-page UX prototype as a real SPA when static HTML is insufficient. Use when the prototype must demonstrate routing, state persistence, dynamic data, or interactive flows that exceed what plain HTML/CSS can convey. Provides a Vite + React + Tailwind + Framer Motion + Lucide scaffold, data-driven page layout, debounced localStorage state, and a clean file structure for `src/`.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Working Prototype App > WHEN: A static HTML/CSS deliverable cannot answer the question being asked of the prototype. Typical triggers: multi-screen flow with routing, state that must persist across reloads, data-driven views, or an interactive demo for stakeholder validation. Below that bar, prefer plain HTML/CSS via `prototype-craft`. ## Choosing static vs working app | Need | Use | |------|-----| | Single page or short flow, visual review only | `prototype-craft` static HTML | | Up to 3 screens with simple click-through | `prototype-craft` + plain anchor links | | Routing, persisted state, dynamic lists, or filtering | This skill | | Real backend integration | A product spike, not a UX prototype | If in doubt, start with static. Promote to a working app only after the static answer becomes hand-wavy. ## Default stack (modify with reason) - Vite (build + dev server) - React 18 (component model) - React Router (routing) -- optional; can stay single-page - Tailwind CSS (utility styling on top of theme tokens) - Framer Motion (motion recipes from `prototype-craft`) - Lucide React (icon set, tree-shakeable) …

How to install
mdr add jnpiyush/agentx/working-prototype-app@sha256:12e93619b604a369The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
