# Figma Designer

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

## Overview

This skill analyzes Figma designs through the available Figma integration and
produces design evidence. `prd-planner` owns product requirements and technical
PRD methodology; this skill supplies visual facts and unresolved design gaps.

## Prerequisites

### Figma MCP Server

Ensure the host exposes a Figma MCP server or plugin before using this skill.
Tool names vary by host and plugin version, so inspect the available Figma tools
in the current session instead of assuming fixed names. The required capability
set is:

- Read file or page metadata
- Read selected nodes or node details
- Read component and style information when available

## 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

```yaml
Input: Figma URL or File Key
  ↓
Extract File Key from URL
  ↓
Call the available Figma metadata tool
  ↓
Call the available Figma node/detail tool
  ↓
Parse frame, component, and text nodes
```

### Phase 2: Extract Design Tokens

Create a comprehensive design token inventory:

```typescript
// 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:

```markdown
## Screen: [Screen Name]

### Layout Structure

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

### Design Specifications

|-------|-------|-------|
| 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 |

| 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: Visual Spec Document (Default)

Generates a design specification document:
```
docs/{feature}-design-spec.md
```

### Option 2: PRD Evidence Pack

Provide screen intent, design tokens, component states, responsive rules,
accessibility observations, and open product questions as inputs to
`prd-planner`. Do not invent business requirements from visual design alone.

## 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 design evidence, 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}
```

## Integration with Other Skills

### Typical Workflow

```
Figma URL → figma-designer → Visual Specs
                                ↓
                           prd-planner → PRD
                                ↓
                           implementation → Code
                                ↓
                           code-reviewer → Quality Check
```

### Handoff to Development

After generating specifications:

```markdown
## Developer Handoff

### Design Files
- Figma: {url}
- Design Spec: {link}

### Design Tokens
- Generated: `tokens.ts`
- Color palette: `colors.ts`
- Typography: `typography.ts`

### Component Library
- Storybook: {url}
- Component docs: {link}

### Assets
- Icons: {folder}
- Images: {folder}
- Exports: {format}
```

## 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
