description	Comprehensive design token architecture and system implementation. Use this skill for token definition and structure, token generation and transformation, design token distribution across platforms, Figma Variables, design token sync automation, and multi-platform token consumption (web, mobile, docs).

Design Tokens System

Comprehensive design token architecture for consistent design systems.

Design tokens are the atomic units of design (colors, spacing, typography). A robust token system ensures consistency across all platforms.

Token Architecture

Four-Layer Token Structure

Base Tokens (Primitives)
  ↓
Semantic Tokens (Context-aware)
  ↓
Component Tokens (Component-specific)
  ↓
Application (Usage)

Layer 1: Base Tokens (Primitives)

{
  "color": {
    "gray-50": "#f9fafb",
    "gray-100": "#f3f4f6",
    "gray-900": "#111827"
  },
  "spacing": {
    "4": "4px",
    "8": "8px",
    "16": "16px"
  }
}

Layer 2: Semantic Tokens (Context-Aware)

{
  "color": {
    "text-primary": "{color.gray-900}",
    "text-secondary": "{color.gray-600}",
    "background-primary": "{color.gray-50}",
    "border": "{color.gray-200}",
    "interactive-primary": "#2563eb",
    "interactive-hover": "#1d4ed8"
  }
}

Layer 3: Component Tokens

{
  "button": {
    "primary": {
      "background": "{color.interactive-primary}",
      "text": "#ffffff",
      "padding": "{spacing.12} {spacing.16}",
      "border-radius": "4px"
    }
  }
}

---

Token Definition Formats

W3C Design Tokens Format

{
  "colors": {
    "primary": {
      "$value": "#2563eb",
      "$description": "Primary brand color",
      "$type": "color"
    }
  },
  "spacing": {
    "md": {
      "$value": "16px",
      "$type": "dimension"
    }
  }
}

Figma Variables Setup

In Figma:

Collections/
  Colors/
    Primary/
      50, 100, 500, 900
  Spacing/
    xs, sm, md, lg, xl
  Typography/
    fontSize, lineHeight, letterSpacing

---

Token Export & Transformation

Export Formats

TypeScript:

export const tokens = {
  color: {
    primary: '#2563eb',
  },
  spacing: {
    md: '16px',
  },
};

CSS Variables:

:root {
  --color-primary: #2563eb;
  --spacing-md: 16px;
}

Tailwind Config:

module.exports = {
  theme: {
    extend: {
      colors: { primary: '#2563eb' },
      spacing: { md: '16px' },
    },
  },
};

JSON:

{
  "color": { "primary": "#2563eb" },
  "spacing": { "md": "16px" }
}

Transform Pipeline

Figma Variables

     ├── → TypeScript
     ├── → CSS
     ├── → Tailwind Config
     └── → Storybook

     ├── → Git Repo

Token Automation

CI/CD Integration

# .github/workflows/token-sync.yml
name: Sync Tokens
on:
  schedule:
    - cron: '0 * * * *'  # Hourly

jobs:
  sync:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - name: Export from Figma
        run: npm run tokens:export
        env:
          FIGMA_TOKEN: ${{ secrets.FIGMA_TOKEN }}
          FIGMA_FILE_ID: ${{ secrets.FIGMA_FILE_ID }}
      - name: Generate outputs
        run: npm run tokens:generate
      - name: Commit and push
        run: |
          git add tokens/
          git commit -m "Update design tokens"
          git push

Token Export Script

// scripts/export-tokens.js
const figmaApi = require('figma-api');

async function exportTokens() {
  const client = new figmaApi.Api({
    personalAccessToken: process.env.FIGMA_TOKEN,
  });

  const file = await client.getFile(process.env.FIGMA_FILE_ID);
  const variables = file.variables;

  // Transform and save
  fs.writeFileSync('tokens/tokens.json', JSON.stringify(variables, null, 2));
}

exportTokens();

Multi-Platform Distribution

Web (TypeScript)

import { tokens } from '@design-system/tokens';

const buttonStyle = {
  background: tokens.color.primary,
  padding: tokens.spacing.md,
};

Web (CSS)

.button {
  background: var(--color-primary);
  padding: var(--spacing-md);
}

Web (Tailwind)

<button class="bg-primary px-md">Button</button>

Mobile (Swift)

import DesignTokens

let color = DesignTokens.color.primary
let spacing = DesignTokens.spacing.md

Documentation (Storybook)

import { tokens } from '@design-system/tokens';

export const ColorPalette = () => (
  <div>
    {Object.entries(tokens.color).map(([name, value]) => (
      <div key={name} style={{ background: value }}>
        {name}: {value}
      </div>
    ))}
  </div>
);

Versioning & Maintenance

Token Updates

Non-Breaking: Color value change

• Patch version bump (1.0.0 → 1.0.1)
• Automatic update in apps

Breaking: Token name change

• Major version bump (1.0.0 → 2.0.0)
• Migration guide required
