Stitch MCP × Antigravity — Design-Driven Development Automation

Design System Automation Pipeline

Stitch MCP manages design systems. Antigravity automates code generation. Together they create a closed-loop design-to-code pipeline.

Step 1: Design System in Stitch

Define design system in Stitch MCP:

# design-system.yaml
name: EnterpriseUI
version: 1.0.0
 
colors:
  primary:
    50: '#F0F4FF'
    500: '#4A7BFF'
    900: '#051D5F'
  danger: '#FF6B35'
 
typography:
  display:
    family: 'IBM Plex Sans'
    size: 48px
    weight: 700
 
spacing:
  xs: 4px
  sm: 8px
  md: 16px
  lg: 24px
 
components:
  Button:
    variants: [primary, secondary, danger]
    sizes: [sm, md, lg, xl]
    states: [default, hover, active, disabled]
 
  TextField:
    variants: [text, email, password]
    states: [empty, filled, error]
 
  Card:
    variants: [elevated, outlined, filled]
    paddings: [sm, md, lg]

Step 2: Sync with Antigravity

Request Antigravity to generate components from Stitch schema:

Generate production React components from Stitch design system:

Source: design-system.yaml
Requirements:
- Tailwind CSS styling
- Full TypeScript types
- Accessibility (ARIA labels)
- Dark mode support
- Responsive design

Outputs:
- src/components/Button.tsx
- src/components/TextField.tsx
- src/components/Card.tsx
- ... (all 50+ components)
- tailwind.config.js (with tokens)
- index.ts (barrel exports)

Antigravity generates all components automatically from tokens.

Step 3: Storybook Auto-Generation

Request Antigravity to create Storybook stories:

Generate Storybook stories for all components:
- Show all variants
- Show all sizes
- Show all states
- Include interactive controls
- Add documentation

Output: src/components/**/*.stories.tsx

Step 4: Test Generation

Generate comprehensive tests:

Create unit tests for all components:
- Render with default props
- Test all variant combinations
- Test accessibility attributes
- Test user interactions
- Generate snapshots

Output: tests/**/*.test.tsx

Step 5: Multi-Framework Output

Generate same components for multiple frameworks:

From single Stitch design system, generate:
1. React components (TypeScript, Tailwind)
2. Vue components (SFC, Tailwind)
3. Web Components (custom elements)
4. Svelte components (reactive, Tailwind)

All synchronized to single design system.

Automated Updates

When design system changes in Stitch:

1. Antigravity detects new/modified tokens
2. Regenerates affected components
3. Updates Tailwind config
4. Regenerates Storybook stories
5. Runs tests to validate
6. Creates PR with changes for review

Production Benefits

• Consistency: All components match design exactly
• Scalability: Add 50+ components in minutes
• Maintainability: Update design once, all components update
• Quality: Automated tests + accessibility checks
• Speed: From design to production components in hours

Implementation Checklist

• [ ] Setup Stitch MCP
• [ ] Define complete design system tokens
• [ ] Create Stitch component specs
• [ ] Connect to Antigravity
• [ ] Generate component library
• [ ] Generate Storybook
• [ ] Generate tests
• [ ] Generate multi-framework variants
• [ ] Setup auto-update pipeline
• [ ] Document for team

Looking back

Stitch MCP + Antigravity eliminates manual component creation. Design once, generate code everywhere. The future of design systems is automated.

Time saved: Weeks of component development → Hours of specification.
