working-prototype-app skillA

working-prototype-app is agent-read markdown (skill) from jnpiyush/agentx: 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/`..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns 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)
