name: site-design-replication description: Crawl, analyze, document, and remix website designs. Extract design systems (colors, typography, spacing), document components with LLM-ready markdown, and create new sites inspired by existing designs. Use when asked to clone a site, extract a design system, create a site like another site, or document UI components.

Site Design Replication & Remix Skill

Overview

This skill enables you to:

1. Crawl & Analyze - Fetch website content and extract design patterns
2. Document - Create LLM-ready markdown documentation of components and styles
3. Remix - Build new sites inspired by existing designs with your own concept

When to Use This Skill

• "Clone this website" / "Copy this site's design"
• "Extract the design system from [URL]"
• "Create a site like [URL] but for [concept]"
• "Document this site's components"
• "What's the color palette of [URL]?"

Step-by-Step Process

Phase 1: Crawl & Extract

1. Fetch the target site using WebFetch tool

2. Identify key elements:

   • Navigation structure
   • Hero section patterns
   • Card/grid layouts
   • Color usage
   • Typography hierarchy
   • Spacing patterns
   • Interactive elements

3. Extract design tokens:

   CopyColors: primary, secondary, accent, neutral scale
   Typography: font families, size scale, weights
   Spacing: base unit, scale (4px, 8px, 16px, etc.)
   Borders: radius values, border widths
   Shadows: elevation levels
   

Phase 2: Document for LLM Context

Create markdown files that can be fed back to LLMs:

1. COMPONENTS.md - Document each component:

   Copy## ComponentName
   
   **Purpose**: What it does
   **Props/Variants**: Configuration options
   **Code**:
   ```tsx
   // Component code here
   

   Copy

2. STYLES.md - Design token documentation:

   Copy## Color Palette
   | Name | Value | Usage |
   |------|-------|-------|
   | primary | #8b5cf6 | CTAs, links |
   
   ## Typography Scale
   | Name | Size | Weight | Line Height |
   |------|------|--------|-------------|
   | h1 | 48px | 700 | 1.2 |
   

3. LLM-CONTEXT.md - High-level architecture summary

Phase 3: Remix & Create

When building a new site inspired by another:

1. Identify transferable patterns:

   • Layout structures
   • Component architecture
   • Animation/interaction patterns
   • Responsive breakpoints

2. Define the new concept:

   • Purpose and audience
   • Unique value proposition
   • Content structure
   • Brand personality

3. Adapt the design:

   • New color palette aligned with concept
   • Adjusted typography for tone
   • Modified components for use case
   • Original content and imagery

Project Structure

When creating a new site, use this structure:

Copyproject-name/
├── app/                    # Next.js App Router pages
│   ├── page.tsx           # Home page
│   ├── layout.tsx         # Root layout
│   └── [feature]/         # Feature pages
├── components/
│   ├── cards/             # Card components
│   ├── hero/              # Hero sections
│   ├── navigation/        # Nav, Footer
│   ├── sections/          # Page sections

└── docs/                  # Documentation
    ├── COMPONENTS.md
    ├── STYLES.md
    └── LLM-CONTEXT.md

Code Templates

See TEMPLATES.md for:

• Next.js 14 setup with Tailwind
• Common component patterns
• Animation utilities
• Dark mode implementation

Best Practices

1. Always document as you build - Future LLMs need context
2. Extract reusable patterns - Don't copy blindly, understand why
3. Respect originality - Remix, don't plagiarize
4. Test responsiveness - Mobile-first approach
5. Optimize for performance - Use Next.js Image, lazy loading

Image Generation Integration

When the design needs custom images:

1. Plan image requirements - List all needed images with descriptions
2. Use AI image generation - MuleRouter, Midjourney, DALL-E
3. Optimize images - Compress and format appropriately
4. Integrate with Next.js Image - Use fill, priority, sizes props

Deployment Checklist

• Build passes without errors
• All images optimized
• Meta tags configured
• Dark mode works
• Mobile responsive
• Push to GitHub
• Deploy to Vercel
