Superdesign Skill

Design principles and workflow from Superdesign - an open source design agent.

Core Principle

When asked to create UI designs, generate 3 variations concurrently for faster iteration.

Design Guidelines

File Output

  • Output to .superdesign/design_iterations/{name}_{n}.html
  • Iterations: table_1.html, table_2.html, table_3.html
  • Sub-iterations: ui_1_1.html, ui_1_2.html

Technical Rules

  1. No images - Use CSS placeholders (no placehold.co either)
  2. Tailwind CSS via CDN - <script src="https://cdn.tailwindcss.com"></script>
  3. Text colors: Only black or white
  4. Spacing: Use 4pt or 8pt system (all margins/padding multiples)
  5. Responsive: Must look good on mobile, tablet, desktop

Design Style

  • Elegant minimalism + functional design
  • Generous white space
  • Clear information hierarchy
  • Subtle shadows, modular card layouts
  • Refined rounded corners

Usage

When user asks for UI design:

1. Create .superdesign/design_iterations/ folder if not exists
2. Generate 3 HTML variations with slight differences:
   - Variation 1: Conservative/clean
   - Variation 2: More creative/bold  
   - Variation 3: Alternative layout
3. Each file is standalone HTML with Tailwind CDN
4. User can preview in browser and pick favorite

Example Prompt

User: "Design a pricing table"

You create:

  • .superdesign/design_iterations/pricing_1.html - Clean 3-column
  • .superdesign/design_iterations/pricing_2.html - Card-based with shadows
  • .superdesign/design_iterations/pricing_3.html - Horizontal comparison

HTML Template

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Design - {name}</title>
  <script src="https://cdn.tailwindcss.com"></script>
</head>
<body class="bg-white text-black">
  <!-- Your design here -->
</body>
</html>

Integration with UI/UX Pro Max

This skill complements ui-ux-pro-max:

  • Superdesign: Quick iteration, 3 variations, visual exploration
  • UI/UX Pro Max: Deep style guides, color palettes, UX best practices

Recommended workflow:

  1. Use UI/UX Pro Max to research style, colors, typography
  2. Use Superdesign to generate 3 variations quickly
  3. User picks favorite, refine with UI/UX Pro Max guidelines
