Figma Designer

"Transform Figma designs into implementation-ready specifications with pixel-perfect accuracy"

Overview

This skill analyzes Figma designs through the Figma MCP server and generates detailed PRDs with precise visual specifications. It extracts design tokens, component specifications, and layout information that developers can implement directly.

Prerequisites

Figma MCP Server

Ensure the Figma MCP server is connected and accessible:

# Check if Figma MCP is available
mcp-list

If not available, install from: https://github.com/modelcontextprotocol/servers

Required Figma MCP tools:

• figma_get_file - Get file metadata
• figma_get_nodes - Get node details
• figma_get_components - Get component information

When This Skill Activates

Activates when you:

• Provide a Figma link (https://www.figma.com/file/...)
• Upload a design screenshot and mention "Figma"
• Say "analyze this design" or "extract design specs"
• Ask to "create PRD from Figma"

Design Analysis Workflow

Phase 1: Fetch Design Data

Input: Figma URL or File Key
  ↓
Extract File Key from URL
  ↓
Call figma_get_file to get metadata
  ↓
Call figma_get_nodes to get design tree
  ↓
Parse frame, component, and text nodes

Phase 2: Extract Design Tokens

Create a comprehensive design token inventory:

// Design Token Structure
interface DesignTokens {
  colors: {
    primary: string[];
    secondary: string[];
    neutral: string[];
    semantic: {
      success: string;
      warning: string;
      error: string;
      info: string;
    };
  };
  typography: {
    fontFamilies: Record<string, string>;
    fontSizes: Record<string, number>;
    fontWeights: Record<string, number>;
    lineHeights: Record<string, number>;
    letterSpacing: Record<string, number>;
  };
  spacing: {
    scale: number;  // 4, 8, 12, 16, etc.
    values: Record<string, number>;
  };
  borders: {
    radii: Record<string, number>;
    widths: Record<string, number>;
  };
  shadows: Array<{
    name: string;
    values: string[];
  }>;
}

Phase 3: Analyze Component Hierarchy

File
├── Frames (Pages/Screens)
│   ├── Component Instances
│   │   ├── Primary Button
│   │   ├── Input Field
│   │   └── Card
│   └── Text Layers
│       ├── Headings
│       ├── Body
│       └── Labels

For each component, extract:

• Props: Size, variant, state
• Layout: Flex direction, alignment, gap, padding
• Styles: Fill, stroke, effects
• Content: Text content, icons, images
• Constraints: Responsive behavior

Phase 4: Generate Visual Specifications

Use this template for each screen:

## Screen: [Screen Name]

### Layout Structure

┌─────────────────────────────────────────┐ │ [Header/Nav] │ ├─────────────────────────────────────────┤ │ │ │ [Main Content] │ │ ┌───────────┐ ┌───────────┐ │ │ │ Card 1 │ │ Card 2 │ │ │ └───────────┘ └───────────┘ │ │ │ ├─────────────────────────────────────────┤ │ [Footer] │ └─────────────────────────────────────────┘

### Design Specifications

#### Colors

| Token | Value | Usage |
|-------|-------|-------|
| Primary | `#007AFF` | Primary buttons, links |
| Background | `#FFFFFF` | Screen background |
| Surface | `#F5F5F7` | Cards, sections |
| Text Primary | `#1C1C1E` | Headings, body |
| Text Secondary | `#8E8E93` | Captions, labels |

#### Typography

| Style | Font | Size | Weight | Line Height | Letter Spacing |
|-------|------|------|--------|------------|---------------|
| Display Large | SF Pro Display | 28px | Bold (700) | 34px | -0.5px |
| Heading 1 | SF Pro Display | 24px | Bold (700) | 32px | -0.3px |
| Heading 2 | SF Pro Display | 20px | Semibold (600) | 28px | -0.2px |
| Body Large | SF Pro Text | 17px | Regular (400) | 24px | -0.4px |
| Body | SF Pro Text | 15px | Regular (400) | 22px | -0.3px |
| Caption | SF Pro Text | 13px | Regular (400) | 18px | -0.1px |

#### Spacing

| Token | Value | Usage |
|-------|-------|-------|
| xs | 4px | Icon padding |
| sm | 8px | Tight spacing |
| md | 12px | Card padding |
| lg | 16px | Section spacing |
| xl | 24px | Large gaps |
| 2xl | 32px | Page margins |

#### Component: Primary Button

```typescript
interface PrimaryButtonProps {
  size?: 'small' | 'medium' | 'large';
  variant?: 'primary' | 'secondary' | 'tertiary';
  disabled?: boolean;
}

// Sizes
size.small = {
  height: 32px,
  paddingHorizontal: 12px,
  fontSize: 15,
  iconSize: 16,
}

size.medium = {
  height: 40px,
  paddingHorizontal: 16px,
  fontSize: 15,
  iconSize: 20,
}

size.large = {
  height: 48px,
  paddingHorizontal: 24px,
  fontSize: 17,
  iconSize: 24,
}

// Variants
variant.primary = {
  backgroundColor: '#007AFF',
  color: '#FFFFFF',
}

variant.secondary = {
  backgroundColor: '#F5F5F7',
  color: '#007AFF',
}

variant.tertiary = {
  backgroundColor: 'transparent',
  color: '#007AFF',
}

Constraints & Responsive Behavior

Element	Constraints	Responsive Behavior
Header	Left, Right, Top	Sticky on scroll
Sidebar	Left, Top, Bottom	Collapses to drawer on mobile
Content	Left, Right (16px)	Full width on mobile

Interaction States

Element	Default	Hover	Pressed	Disabled
Primary Button	opacity: 1	opacity: 0.8	opacity: 0.6	opacity: 0.4
Icon Button	opacity: 1	background: rgba(0,0,0,0.05)	background: rgba(0,0,0,0.1)	opacity: 0.3
Card	shadow: sm	shadow: md	-	opacity: 0.6

## Output Formats

### Option 1: Full PRD (Recommended)

Generates a complete 4-file PRD:
- `docs/{feature}-notes.md` - Design decisions
- `docs/{feature}-task-plan.md` - Implementation tasks
- `docs/{feature}-prd.md` - Product requirements
- `docs/{feature}-tech.md` - Technical specifications

### Option 2: Visual Spec Document

Generates a design specification document:

docs/{feature}-design-spec.md

### Option 3: Component Library

For design systems, generates:

src/components/ ├── Button/ │ ├── Button.tsx │ ├── Button.test.tsx │ └── Button.stories.tsx ├── Input/ ├── Card/ └── tokens.ts

## Quick Reference: Design Token Categories

### Always Extract These

| Category | What to Extract | Why |
|----------|----------------|-----|
| **Colors** | Hex/RGBA values | Theme consistency |
| **Typography** | Font family, size, weight, spacing | Text hierarchy |
| **Spacing** | Padding, margin, gap values | Layout alignment |
| **Borders** | Radius, width values | Shape consistency |
| **Shadows** | Offset, blur, spread, color | Depth perception |
| **Icons** | Name, size, color | Visual consistency |
| **Images** | URL, dimensions, fit mode | Asset management |

## Design Review Checklist

Before generating PRD, verify:

- [ ] All screens are accounted for
- [ ] Design tokens are extracted
- [ ] Component variants are documented
- [ ] Responsive behavior is specified
- [ ] Interaction states are defined
- [ ] Accessibility (WCAG) is considered
  - [ ] Color contrast ratio ≥ 4.5:1
  - [ ] Touch targets ≥ 44x44px
  - [ ] Focus indicators visible

## Frame Analysis Template

For each frame/screen in the Figma file:

```markdown
## Frame: {Frame Name}

### Purpose
{What this screen does}

### Elements

| Element | Type | Styles | Props |
|---------|------|--------|-------|
| {Name} | {Component/Text/Vector} | {css} | {props} |
| {Name} | {Component/Text/Vector} | {css} | {props} |

### Layout
- Container: {width, height, fill}
- Position: {absolute/relative}
- Constraints: {left, right, top, bottom}
- Auto Layout: {direction, spacing, padding, alignment}

### Content Hierarchy
1. {Primary element}
2. {Secondary element}
3. {Tertiary element}

### Notes
{Any special considerations}

Best Practices

DO

✅ Extract exact pixel values for critical dimensions ✅ Document component variants and states ✅ Include responsive breakpoints ✅ Note any platform differences (iOS vs Android) ✅ Include accessibility considerations ✅ Export design tokens as constants

DON'T

❌ Round spacing values (use exact 4px/8px/12px) ❌ Ignore hover/focus states ❌ Skip constraint behavior ❌ Forget about empty states ❌ Omit loading states ❌ Assume platform defaults without verification
