majiayu000 Design-to-Code Skill (Vision AI)
Overview
Transform design screenshots, Figma exports, and mockups into pixel-perfect React components using Claude's multimodal vision capabilities. Upload an image, get production code with exact spacing, colors, typography, and all visual states.
This is the flagship SOTA feature - leverages Claude's vision models for design analysis.
How It Works
1. Upload Design
Supported formats:
- Screenshots: PNG, JPG from any design tool
- Figma exports: Frame exports, component screenshots
- Mockups: Photoshop, Sketch, XD exports
- Photos: Even hand-drawn sketches (with lower accuracy)
2. Vision AI Analysis
Claude's vision model extracts:
{
"component_type": "card",
"layout": {
"type": "flex",
"direction": "column",
"align": "stretch",
"gap": "16px",
"padding": "24px"
},
"spacing": {
"padding": "24px",
"gap_vertical": "16px",
"gap_horizontal": "12px",
"border_radius": "8px"
},
"colors": {
"background": "#FFFFFF",
"text_primary": "#1F2937",
"text_secondary": "#6B7280",

"mobile": { "padding": "16px", "font_size_heading": "20px" },
"desktop": { "padding": "24px", "font_size_heading": "24px" }
}
}
3. Generate Component Code
Example: Product Card from Screenshot
// Generated from design screenshot
import { ShoppingCart } from 'lucide-react';
interface ProductCardProps {
product: {
image: string;
title: string;
description: string;
price: number;
rating: number;
};
onAddToCart: () => void;
}
export function ProductCard({ product, onAddToCart }: ProductCardProps) {
return (
<article className="flex flex-col rounded-lg border border-gray-200 overflow-hidden hover:shadow-lg transition-shadow">
{/* ✨ Extracted: 200px height, cover fit */}
<img
src={product.image}
alt={product.title}
className="w-full h-[200px] object-cover"
/>
{/* ✨ Extracted: 24px padding, 16px gap */}
<div className="flex flex-col gap-4 p-6">
{/* ✨ Extracted: 24px size, 700 weight */}
<h3 className="text-2xl font-bold text-gray-900">
{product.title}
</h3>
{/* ✨ Extracted: 16px size, gray-600 color */}
<p className="text-base text-gray-600 line-clamp-2">
{product.description}
</p>
{/* ✨ Extracted: flex layout, space-between */}
<div className="flex items-center justify-between">
<span className="text-xl font-semibold text-gray-900">
${product.price.toFixed(2)}
</span>
{/* ✨ Extracted: blue button with icon */}
<button
className="flex items-center gap-2 px-4 py-2 bg-blue-500 text-white rounded-md hover:bg-blue-600 transition-colors"
>
<ShoppingCart size={18} />
Add to Cart
</button>
</div>
</div>
</article>
);
}
4. Extract Design Tokens
Create reusable design system:
/* Generated design tokens from screenshot */
/* Colors */
--color-primary: #2196F3;
--color-bg: #FFFFFF;
--color-text-primary: #1F2937;
--color-text-secondary: #6B7280;
--color-border: #E5E7EB;
/* Typography */
--font-size-h1: 24px;
--font-size-body: 16px;
--font-size-caption: 14px;
--font-weight-bold: 700;
--font-weight-medium: 500;
--font-weight-normal: 400;
--line-height-tight: 1.2;
--line-height-normal: 1.5;
/* Spacing */
--space-2: 8px;
--space-3: 12px;
--space-4: 16px;
--space-6: 24px;
/* Borders */
--radius-md: 8px;
--border-width: 1px;
5. Generate All Variants
Vision AI detects states from visual cues:
// Detected hover state (darker shadow, lifted appearance)
export const Hover: Story = {
parameters: {
pseudo: { hover: true },
},
};
// Detected focused state (blue outline ring)
export const Focused: Story = {
parameters: {
pseudo: { focus: true },
},
};
// Detected disabled state (grayed out, reduced opacity)
export const Disabled: Story = {
args: {
disabled: true,
},
};
Advanced Features
Multi-Design Analysis
Upload multiple screenshots to extract design system:
User uploads:
- button-primary.png
- button-secondary.png
- card-default.png
- card-featured.png
AI extracts:
- Color palette (all unique colors across designs)
- Typography scale (all font sizes used)
- Spacing system (common spacing values)
- Component variants (primary vs secondary button)
Responsive Detection
If multiple screenshots provided (mobile + desktop):
// Desktop
<div className="hidden md:flex md:p-6">
// Mobile
<div className="flex p-4 md:hidden">
// Responsive
<h1 className="text-xl md:text-2xl">
State Inference
Vision AI infers states from design:
Detected patterns:
- Darker color → Hover state
- Blue outline → Focus state
- Reduced opacity → Disabled state
- Spinner/loading indicator → Loading state
- Red border → Error state
- Green checkmark → Success state
Component Recognition
AI identifies component types:
- Button: Rectangular, text + optional icon, solid background
- Card: Container with border/shadow, multiple child elements
- Input: Text field with border, optional label
- Modal: Centered overlay with backdrop
- Nav: Horizontal/vertical list of links
- Table: Grid of data with headers
- Form: Multiple inputs with labels and submit button
Workflow Example
User Uploads Pricing Card Screenshot
AI Analysis:
Detected:
- Component: Pricing Card
- Layout: Vertical stack, centered content
- Sections: Header (icon + title), Price (large number), Features (list), CTA (button)
- Colors: Purple primary (#8B5CF6), White BG, Gray text
- Spacing: 32px padding, 16px gap between sections
- Typography: 48px price, 24px title, 16px features
- Border: 1px solid, 12px radius
- States: Default + Featured (purple border, purple BG for header)
Generated Code:
interface PricingCardProps {
plan: {
name: string;
price: number;
features: string[];
icon: React.ReactNode;
};
featured?: boolean;
onSelect: () => void;
}
export function PricingCard({ plan, featured = false, onSelect }: PricingCardProps) {
return (
<div
className={`
flex flex-col gap-4 p-8 rounded-xl border
${featured ? 'border-purple-500 bg-purple-50' : 'border-gray-200 bg-white'}
`}
>
{/* Header */}
<div className="flex items-center gap-3">
<div className="text-purple-500">{plan.icon}</div>
<h3 className="text-2xl font-bold">{plan.name}</h3>
</div>
{/* Price */}
<div className="flex items-baseline gap-1">
<span className="text-5xl font-bold">${plan.price}</span>
<span className="text-gray-600">/month</span>
</div>
{/* Features */}
<ul className="flex flex-col gap-2">
{plan.features.map(feature => (
<li key={feature} className="flex items-center gap-2">
<Check className="text-purple-500" size={16} />
<span>{feature}</span>
</li>
))}
</ul>
{/* CTA */}
<button
className={`
mt-4 px-6 py-3 rounded-lg font-semibold transition-colors
${featured
? 'bg-purple-500 text-white hover:bg-purple-600'
: 'bg-gray-100 text-gray-900 hover:bg-gray-200'
}
`}
>
{featured ? 'Get Started' : 'Select Plan'}
</button>
</div>
);
}
Generated Stories:
export const Basic: Story = {
args: {
plan: {
name: 'Starter',
price: 9,
features: ['Feature 1', 'Feature 2', 'Feature 3'],
icon: <Star />,
},
},
};
export const Featured: Story = {
args: {
...Basic.args,
featured: true,
},
};
Accuracy & Limitations
High Accuracy For:
- ✅ Layout structure (flex, grid, positioning)
- ✅ Spacing measurements (padding, gap, margin)
- ✅ Colors (exact hex values from screenshots)
- ✅ Typography (font sizes, weights)
- ✅ Component types (button, card, input, etc.)
Challenges:
- ⚠️ Subtle spacing (1-2px differences)
- ⚠️ Complex animations (CSS/JS required)
- ⚠️ Custom fonts (may default to system fonts)
- ⚠️ Low-resolution images (pixelation)
- ⚠️ Hand-drawn sketches (approximate)
Recommendations:
- Use high-resolution screenshots (2x or 3x)
- Include multiple states if possible (hover, focus, etc.)
- Provide design system context (color names, spacing scale)
- Review and refine generated code
Integration with Design Tools
Figma Plugin (Future)
Direct integration with Figma API:
- Select frame → Generate code
- Auto-sync design updates
- Extract design tokens automatically
Sketch/XD
Export artboards → Upload to Claude → Generate code
Commands
/design-to-code
Interactive workflow:
- User provides image (upload or URL)
- AI analyzes and shows extracted data
- User confirms or adjusts
- AI generates component + stories + tokens
/extract-design-tokens
Extract only design tokens from multiple screenshots:
- Colors, typography, spacing
- Output as CSS variables or JSON
Best Practices
For Best Results:
- High resolution: 2x or 3x screenshots
- Clean backgrounds: Remove noise, distractions
- Clear states: Separate screenshots for hover/focus/disabled
- Annotate if needed: Add notes about behavior
- Provide context: Mention design system if you have one
Review Generated Code:
- ✅ Check responsive breakpoints
- ✅ Verify accessibility attributes
- ✅ Test keyboard navigation
- ✅ Adjust animations (AI can't infer timing)
- ✅ Add business logic (AI generates UI only)
