Skill: Design React Components from Figma

This skill analyzes Figma designs and proposes React component architecture and props APIs. It helps bridge the gap between design and implementation by providing clear specifications before coding begins.

When to Use

• User provides a Figma URL and wants to understand how to implement it as React
• Planning component architecture before implementation
• Determining what props a component should have based on Figma variants
• Deciding if a Figma component should be one or multiple React components

What This Skill Does NOT Do

• Build or implement the actual React components
• Generate production code
• Create Code Connect mappings (use figma-connect-component for that)
• Sync existing components with Figma (use figma-component-sync for that)

Required Inputs

1. Figma URL: Full URL like https://figma.com/design/{fileKey}/{fileName}?node-id={nodeId}

Design Principle

Follow FIGMA structure exactly

When designing component APIs from Figma:

• DO NOT use any other component library as a reference
• DO NOT impose external component patterns or best practices
• DO use the Figma design as the single source of truth for component structure
• DO match the exact component hierarchy, variant structure, and prop organization shown in Figma

The component API should mirror how the design is structured in Figma, not how a component library would implement it. If Figma shows variants that change DOM structure, layout, or element ordering, the component API should reflect those structural changes through props.

Example:

• If Figma shows a Type="Mobile" variant with vertical button layout and Type="Desktop" with horizontal layout
• Then the component should have a type prop that controls both layout structure and alignment
• NOT separate props like buttonLayout="vertical" and textAlign="center" which would deviate from the Figma structure

Workflow Overview

┌─────────────────────────────────────────────────────────────────┐
│ 1. FETCH - Get Figma design context using MCP                  │
├─────────────────────────────────────────────────────────────────┤
│ 2. VALIDATE - Screenshot verification                           │
├─────────────────────────────────────────────────────────────────┤
│ 3. SAVE - Store design context in .temp/design-components/     │
├─────────────────────────────────────────────────────────────────┤
│ 4. ANALYZE - Review variants, properties, and nested components│
├─────────────────────────────────────────────────────────────────┤
│ 5. PROPOSE - Suggest component API(s) with props and types     │
└─────────────────────────────────────────────────────────────────┘

Required Flow

Follow this sequence exactly:

1. Run get_design_context first to fetch the structured representation for the exact node(s).

2. If the response is too large or truncated, run get_metadata to get the high-level node map and then re-fetch only the required node(s) with get_design_context.

3. Run get_screenshot for a visual reference of the node variant being implemented.

4. Only after you have both get_design_context and get_screenshot, download any assets needed and start implementation.

5. Translate the output into this project's conventions, styles and framework. Reuse the project's color tokens, components, and typography wherever possible.

6. Validate against Figma for 1:1 look and behavior before marking complete.

Step-by-Step Instructions

Step 1: Parse Figma URL and Fetch Design Context

Extract from the URL:

• fileKey: The ID after /design/ (or after /branch/ if on a branch)
• nodeId: From node-id= query param (convert 123-456 → 123:456)

Call mcp_figma_get_design_context with:

• nodeId: The extracted node ID
• fileKey: The extracted file key

Step 2: Create Output Directory and Save Design Context

Create the output directory:

.temp/design-components/{COMPONENT_NAME}/

Where {COMPONENT_NAME} is derived from the Figma component name (kebab-case).

Save the design context to .temp/design-components/{COMPONENT_NAME}/design-context.md:

# Design Context: {ComponentName}

## Figma Source
{original URL}

## Component Overview
{Brief description based on Figma data}

## Raw Design Data
{Full output from mcp_figma_get_design_context}

Step 3: Analyze Figma Design

Extract and analyze:

1. Variants and Variant Options

   • List all variant properties (e.g., Size, State, Type)
   • List all options for each variant (e.g., Size: Small, Medium, Large)
   • Note how variants affect component structure, not just styling
     • Does the variant change element ordering?
     • Does it change flex direction or layout?
     • Does it add/remove elements?
     • Does it change text alignment or button positioning?

2. Component Properties

   • Boolean properties (e.g., "Has Icon", "Show Label")
   • String properties (e.g., "Label Text")
   • Instance swap properties (e.g., "Icon")

3. Nested Components

   • Child component instances
   • Repeated elements

4. Text Layers

   • Configurable text content
   • Alignment changes across variants

5. Structural Differences

   • Document how the DOM structure changes between variants

6. Child Component Configurability Assessment

   When the parent component contains nested child component instances (e.g., a Dialog containing Buttons), critically evaluate whether those child components should be configurable by the user.

   Common Design Pattern Gap: Designers may focus on the parent component's variants without considering that child component instances might need different configurations based on the use case. For example:

   • An AlertDialog might always show the same "Cancel" and "Delete" buttons in Figma
   • But in actual usage, different dialogs need different button variants (destructive vs. primary), labels, and actions

   When to Recommend Configurable Child Props:

   Consider making child components configurable if:

   • The child has multiple variants in its own component set (e.g., Button has primary/destructive/outline variants)
   • Different use cases would require different child configurations
   • The child component's content or behavior naturally varies (button labels, icons, actions)
   • The design shows only one variant but others exist and are relevant

   How to Handle in API Design:

   Instead of hardcoding child components, provide render prop or component prop patterns:

Step 4: Propose Component API

Based on the analysis, create .temp/design-components/{COMPONENT_NAME}/proposed-api.md:

# Proposed API: {ComponentName}

## Figma Source
{original URL}

## Summary
{One paragraph describing what this component does}

## Recommended Component Structure

{Explain if this should be one component or multiple, and why}

---

## Component: {ComponentName}

### Props Interface

\`\`\`typescript
interface {ComponentName}Props {
  // Mapped from Figma variant "Size"
  size?: 'sm' | 'md' | 'lg';
  
  // Mapped from Figma variant "Variant"
  variant?: 'primary' | 'secondary' | 'outline';
  
  // Mapped from Figma boolean "Disabled"
  disabled?: boolean;
  
  // Mapped from Figma text layer "Label"
  children: React.ReactNode;
  
  // Mapped from Figma instance "Icon"
  icon?: React.ReactNode;
}
\`\`\`

### Prop Details

| Prop | Type | Default | Figma Source | Notes |
|------|------|---------|--------------|-------|
| size | `'sm' \| 'md' \| 'lg'` | `'md'` | Variant: Size | Maps Small→sm, Medium→md, Large→lg |
| variant | `'primary' \| 'secondary'` | `'primary'` | Variant: Type | - |
| disabled | `boolean` | `false` | Boolean: Disabled | - |
| children | `React.ReactNode` | required | Text: Label | - |
| icon | `React.ReactNode` | `undefined` | Instance: Icon | Only shown when Has Icon=true |

### Excluded from Props (Handled by Tailwind/Internal State)

| Figma Property | Reason |
|----------------|--------|
| State: Hover | Tailwind `hover:` modifier |
| State: Pressed | Tailwind `active:` modifier |
| State: Focused | Tailwind `focus-visible:` modifier |

### Example Usage

\`\`\`tsx
<{ComponentName} size="lg" variant="primary">
  Click me
</{ComponentName}>

<{ComponentName} size="sm" icon={<IconPlus />}>
  Add Item
</{ComponentName}>
\`\`\`

## Additional Components (if applicable)

{If the Figma component should be split into multiple React components, document each one here with the same structure}

Decision Guidelines

When to Create Multiple Components

Create separate components when:

• Figma variants represent fundamentally different UI patterns (e.g., "Type: Text Input" vs "Type: Date Picker")
• Variants have completely different props/behavior
• One variant is a specialized version with unique functionality

Keep as one component when:

• Variants only affect styling (colors, sizes)
• All variants share the same props interface
• Behavior is consistent across variants

Props to Include vs Exclude

Include as props:

• Variants that change content, behavior, OR structure
• Boolean toggles for optional elements
• Text content that should be configurable
• Instance swaps for customizable slots

Exclude from props (handle internally):

• Pseudo-state variants: hover, pressed, focused, active
• Interaction states: loading might be a prop, but visual feedback is internal
• Animation states

Naming Conventions

Figma	React Prop
Small, Medium, Large	'sm', 'md', 'lg'
Primary, Secondary	'primary', 'secondary'
Has Icon, Show Label	hasIcon: boolean, showLabel: boolean
Yes/No, True/False	boolean
Title Case values	kebab-case or camelCase
