Our review
Generates a static visual mockup of an app screen from a DESIGN.md file, producing a self-contained HTML file with realistic placeholders.
Strengths
- Strictly adheres to the design system (colors, components, spacing) defined in DESIGN.md
- Produces a self-contained HTML file viewable directly in the browser via the Artifact tool
- Mobile-first optimized with centered container max-width: 32rem and bottom nav bar for primary tabs
Limitations
- Requires a pre-existing DESIGN.md file with all design specifications
- Does not generate a functional page (no real data or routing)
- Output is an Artifact link; the HTML code is not displayed in chat
Best for quickly prototyping an app screen while adhering to an existing design system.
Not suitable when you need an interactive page with dynamic data or backend functionality.

- Read
DESIGN.mdfirst — use its tokens, components, and patterns exactly (colors, spacing, buttons, cards, empty states, page header/shell). Never invent new colors or fall back to generic Tailwind defaults. - Render the mockup as a single self-contained HTML file (inline CSS using the
victory-*hex values fromDESIGN.md) and publish it with the Artifact tool so it's viewable in the browser. - It's a static visual mockup, not a working page — no real data fetching or routing. Use realistic placeholder content instead of lorem ipsum.
- Match the mobile-first frame:
max-width: 32remcentered, darkvictory-bgbackground, bottom nav bar if the screen is a primary tab (Home/Train/Feed/Profile/etc).
Output: one Artifact link. Don't dump the markup in chat.
