# Design Tools Integration Specialist

Comprehensive design-to-code workflow guidance covering three major capabilities: Figma MCP (design fetching), Pencil MCP (visual rendering), and Pencil-to-code export (React/Tailwind generation).

## Default Design Style (shadcn/ui Nova)

When no specific design style is requested, use the **shadcn/ui Nova** preset with Notion-style neutral color scheme:

```
bunx --bun shadcn@latest create --preset "https://ui.shadcn.com/init?base=radix&style=nova&baseColor=neutral&theme=neutral&iconLibrary=hugeicons&font=noto-sans&menuAccent=bold&menuColor=default&radius=small&template=next&rtl=false" --template next
```

### Nova Style Configuration

| Property | Value | Description |
|----------|-------|-------------|
| Style | `nova` | Modern, clean design language |
| Base Color | `neutral` | Notion-style grayscale palette |
| Theme | `neutral` | Consistent neutral theming |
| Icon Library | `hugeicons` | Comprehensive icon set |
| Font | `noto-sans` | Clean, readable sans-serif |
| Radius | `small` | Subtle rounded corners |
| Menu Accent | `bold` | Strong menu highlighting |

### When to Use Default Style

Apply the Nova preset when:
- User requests "clean", "modern", or "minimalist" design without specifics
- No brand guidelines or design system specified
- Creating dashboards, admin panels, or productivity tools
- Building documentation or content-focused interfaces

## Quick Tool Selection

### Figma MCP - Design Context Fetching

Figma integration for fetching design context, metadata, and screenshots from Figma files.

Best For: Fetching design tokens, component specifications, layout information, and style guides from existing Figma files. Extracting design system values and understanding design structure.

Key Strengths: Direct access to Figma file metadata, component hierarchy extraction, style guide generation, design token retrieval, screenshot capture for visual reference.

Workflow: Connect to Figma file → Fetch file metadata → Extract component tree → Retrieve design tokens → Generate style documentation.

Context7 Library: /figma/docs

### Pencil MCP - Visual Design Rendering

Pencil MCP integration for creating and editing .pen design files with AI-assisted design generation.

Best For: Rapid prototyping, visual design iterations, creating UI mockups from text descriptions, collaborative design discussions, visual proposals before implementation.

Key Strengths: Text-to-design conversion, batch design operations, style guide integration, visual preview without implementation, collaborative design workflow.

**Available Pencil MCP Tools:**

| Tool | Purpose |
|------|---------|
| `batch_design` | Create, modify, and manipulate design elements in batches |
| `batch_get` | Read design components and hierarchy by patterns or node IDs |
| `get_screenshot` | Render design previews as images |
| `snapshot_layout` | Analyze computed layout structure |
| `get_editor_state` | Get current editor context and active file |
| `get_variables` | Read design tokens and theme variables |
| `set_variables` | Update design tokens and theme variables |
| `get_guidelines` | Get design guidelines for code, tables, Tailwind, or landing pages |
| `get_style_guide` | Get style guide by name or tags |
| `get_style_guide_tags` | List all available style guide tags |
| `open_document` | Open existing .pen file or create new one |
| `find_empty_space_on_canvas` | Find available space for new elements |

Workflow: Describe UI in natural language → Generate design with batch_design → Visually review with get_screenshot → Iterate on design → Export to code when ready.

Context7 Library: /pencil/docs

### Pencil-to-Code Export - React/Tailwind Generation

Export .pen designs to production-ready React and Tailwind CSS code.

Best For: Converting approved .pen designs to implementation, generating React components with Tailwind styling, maintaining design fidelity in code, rapid frontend development from visual designs.

Key Strengths: Design-to-code automation, React component generation, Tailwind CSS styling, responsive layout handling, component structure preservation, design system integration.

Workflow: Finalize .pen design → Configure export options → Generate React components → Apply Tailwind classes → Review generated code → Integrate into project.

## Quick Decision Guide

Choose Figma MCP when:
- Need to extract design context from existing Figma files
- Working with designers who use Figma
- Required to fetch design tokens and component specifications
- Need screenshots or visual references from Figma
- Documenting existing design systems

Choose Pencil MCP when:
- Creating new designs from scratch
- Rapid prototyping and visual iteration needed
- Text-based design workflow preferred
- Want AI-assisted design generation
- Collaborative design discussions with team

Choose Pencil-to-Code Export when:
- Design is finalized in .pen format
- Ready to implement visual designs as code
- Need React components with Tailwind styling
- Maintaining design fidelity is critical
- Rapid frontend development from designs

## Pencil MCP Workflow

### Starting a Design Session

1. **Check Editor State**
   ```
   get_editor_state() → Determine active .pen file and user selection
   ```

2. **Open or Create Document**
   ```
   open_document(filePathOrNew: "new") → Create new .pen file
   open_document(filePathOrNew: "/path/to/file.pen") → Open existing
   ```

3. **Get Design Guidelines**
   ```
   get_guidelines(topic: "code" | "table" | "tailwind" | "landing-page")
   get_style_guide_tags() → Get available style tags
   get_style_guide(tags: ["minimalist", "dashboard"], name: "nova")
   ```

### Creating Designs

1. **Generate with batch_design**

   Use batch_design for efficient batch operations. Syntax:
   ```
   foo=I("parent", { ... })    // Insert new node
   baz=C("nodeid", "parent", { ... })  // Copy node
   foo2=R("nodeid1/nodeid2", {...})    // Replace node
   U(foo+"/nodeid", {...})     // Update node
   D("dfFAeg2")               // Delete node
   M("nodeid3", "parent", 2)   // Move node
   G("baz", "ai", "...")       // Generate image with AI
   ```

2. **Design with Default Nova Style**

   When creating components without user-specified style:
   - Use neutral color palette (grays, whites)
   - Apply small radius (4-6px)
   - Use Noto Sans or system sans-serif
   - Maintain clean, minimal aesthetic
   - Apply consistent 4px/8px spacing grid

3. **Review with get_screenshot**
   ```
   get_screenshot() → Visual validation of design
   ```

### Managing Design Tokens

1. **Read Variables**
   ```
   get_variables() → Current design tokens and themes
   ```

2. **Update Variables**
   ```
   set_variables(variables: { primary: "#3B82F6", ... })
   ```

### Layout Analysis

```
snapshot_layout() → Analyze computed layout rectangles
find_empty_space_on_canvas(direction: "right", size: { w: 200, h: 100 })
```

## Common Design-to-Code Patterns

### Universal Patterns

These patterns apply across all three tools with tool-specific implementations.

**Design Token Management:**

All tools support design token extraction and management. Figma MCP extracts tokens from existing files, Pencil MCP generates tokens during design creation, Pencil-to-code exports tokens as CSS variables or Tailwind config.

**Component Architecture:**

All tools maintain component hierarchy. Figma MCP reads component structure from Figma, Pencil MCP creates component structure in DNA codes, Pencil-to-code generates React components preserving hierarchy.

**Responsive Design:**

All tools handle responsive layouts. Figma MCP extracts responsive variants, Pencil MCP defines responsive breakpoints in DNA, Pencil-to-code generates Tailwind responsive classes.

**Style Consistency:**

All tools ensure design consistency. Figma MCP validates against design system, Pencil MCP enforces design tokens, Pencil-to-code applies consistent Tailwind classes.

### Workflow Best Practices

Applicable to all tools:

**Design System Integration:**
- Define design tokens before starting design work
- Use consistent naming conventions across tools
- Maintain single source of truth for design values
- Document token usage and component patterns

**Version Control:**
- Commit Figma metadata snapshots for reference
- Version .pen files in repository
- Track design iterations with git
- Document design decisions in code comments

**Collaboration:**
- Use Figma comments for design feedback
- Share .pen frames for visual review
- Create pull requests for design changes
- Maintain design documentation alongside code

**Quality Assurance:**
- Validate design tokens against style guide
- Test responsive breakpoints
- Verify accessibility compliance
- Review generated code for optimization
