design-analyzer（设计分析器）

Design Analyzer Skill

Purpose

Fetch and extract technical requirements from design references (Figma URLs, screenshots, mockups) for CMS component implementation.

CRITICAL FIRST STEP: This skill MUST actively fetch design data using available tools (Figma MCP, Read tool) before performing any analysis. Never guess or infer design specifications - always fetch the actual design first.

Philosophy

Accurate design-to-code translation requires systematic extraction of technical specifications.

Core Beliefs

1. Precision Over Interpretation: Extract exact values, don't guess or estimate
2. Accessibility from the Start: Check contrast and touch targets during analysis
3. Responsive by Default: Design for mobile first, enhance for desktop
4. Document Technical Decisions: Record exact colors, spacing, typography for reproducibility

Why Design Analysis Matters

• Pixel-Perfect Implementation: Faithful translation of designer intent
• Consistent Experiences: Same colors, spacing, typography across components
• Accessibility Compliance: Catch contrast and touch target issues early
• Developer Efficiency: Clear specs eliminate guesswork

When This Skill Activates

This skill automatically activates when:

• User mentions Figma URL or Figma design
• User uploads an image file (.png,.jpg,.jpeg,.webp,.svg)
• User says phrases like:

- "implement this design" - "create a component from this mockup" - "build this layout" - "convert this design to [WordPress/Drupal]"

• User asks to analyze visual design elements
• User references a "screenshot" or "wireframe"

Decision Framework

Before analyzing a design, determine:

What's the Design Source?

1. Figma URL → Extract artboard structure, exact values from design tokens
2. Screenshot/Image → Visual analysis, estimate values, measure ratios
3. Wireframe → Structure only, minimal styling details
4. Partial mockup → Analyze what's visible, note missing context

What's the Target Platform?

WordPress:

• Map to native blocks (Group, Heading, Paragraph, Buttons, Image, Columns)
• Output: Block pattern PHP file + SCSS
• Focus: Block composition and responsive classes

Drupal:

• Map to paragraph fields (text, image, link, entity reference)
• Output: Paragraph type YAML + Twig + SCSS
• Focus: Field structure and view modes

What Components Are Visible?

Layout patterns:

• Hero sections → Full-width container with content overlay
• Card grids → Repeating cards with consistent spacing
• Feature lists → Icon + heading + text patterns
• Navigation → Header with menu items

Interactive elements:

• Buttons → Identify all button states (default, hover, focus, active)
• Forms → Note input types, labels, validation states
• Links → Check text links vs. button styles

What Technical Specs Are Needed?

Always extract:

• ✅ Colors - Hex values, opacity, contrast ratios
• ✅ Typography - Font families, sizes, weights, line heights
• ✅ Spacing - Margins, padding, gaps (in px or rem)
• ✅ Layout - Grid columns, flex direction, alignment

Check for accessibility:

• ✅ Contrast ratios - Calculate for all text (4.5:1 minimum)
• ✅ Touch targets - Verify buttons ≥ 44x44px on mobile
• ✅ Focus indicators - Note if visible focus states exist

What Responsive Behavior?

Analyze breakpoints:

• Mobile (< 768px) - Stacked layout, larger touch targets
• Tablet (768-1023px) - Mixed layout, medium spacing
• Desktop (1024px+) - Full layout, smaller relative spacing

Common responsive patterns:

• Columns → Stack on mobile, side-by-side on desktop
• Font sizes → Smaller base on mobile, larger on desktop
• Images → Full width on mobile, constrained on desktop

Capabilities

Design Input Fetching & Processing

CRITICAL: This skill actively FETCHES design data before analysis:

• Figma URLs:

- ✅ Use Figma MCP to fetch design context and code - ✅ Use Figma MCP to capture screenshots - ✅ Extract exact values from Figma design tokens - ✅ Download image assets locally - Extract node IDs, artboard names, frame structure

• Screenshots:

- ✅ Read image files using Read tool - Analyze visual hierarchy, layout patterns, UI components

• Mockups: Identify design system elements, spacing, typography
• Wireframes: Extract structure and content relationships

Component Identification

• Recognize common patterns: heroes, CTAs, cards, galleries, slideshows
• Map sections to CMS components (WordPress blocks, Drupal paragraphs)
• Identify reusable patterns vs. unique implementations
• Detect interactive elements requiring JavaScript

Technical Extraction

• Colors: Extract hex codes, identify primary/secondary/accent colors
• Typography: Font families, sizes, weights, line-heights
• Spacing: Margins, padding, gaps (in px, rem, or relative units)
• Layout: Grid systems, flexbox patterns, column structures
• Breakpoints: Responsive design requirements
• Interactions: Hover states, animations, transitions

Analysis Process

0. Fetch Design Data (CRITICAL FIRST STEP)

Before any analysis, you MUST fetch the actual design data:

For Figma URLs:

STEP 1: Load Figma MCP Tools

Use ToolSearch to load Figma tools FIRST:
ToolSearch(query: "select:mcp__plugin_figma_figma__get_design_context")
ToolSearch(query: "select:mcp__plugin_figma_figma__get_screenshot")

STEP 2: Parse Figma URL

URL format: https://figma.com/design/{fileKey}?node-id={nodeId}
Example: https://figma.com/design/ABC123XYZ?node-id=16981-81661

Extract:
- fileKey: "ABC123XYZ"
- nodeId: "16981:81661" (IMPORTANT: Replace hyphen with colon!)

STEP 3: Fetch Design Context

Call Figma MCP to get design structure and code:
mcp__plugin_figma_figma__get_design_context(
  fileKey: {extracted fileKey},
  nodeId: {extracted nodeId with colon},
  clientLanguages: "html,css,scss",
  clientFrameworks: "wordpress" | "drupal"
)

Returns:
- React/Tailwind code (will need conversion to native WordPress/Drupal)
- Exact CSS values (colors, spacing, typography from Figma)
- Image asset URLs (valid for 7 days)
- Design token information

STEP 4: Get Visual Screenshot

Call Figma MCP to get visual reference:
mcp__plugin_figma_figma__get_screenshot(
  fileKey: {same fileKey},
  nodeId: {same nodeId with colon},
  clientLanguages: "html,css,scss",
  clientFrameworks: "wordpress" | "drupal"
)

Returns: Visual image for analysis

STEP 5: Extract Design Specifications

From the Figma data, extract:

• Colors: Exact hex codes from CSS values in code output
• Typography: Font families, sizes (px), weights, line-heights from code
• Spacing: Margins, padding, gaps from Tailwind classes or CSS
• Layout: Flexbox, grid, positioning from class names
• Images: Download URLs for all assets (imgVariable = "https://...")
• Dimensions: Width, height, border-radius values
• Effects: Shadows, gradients, opacity

STEP 6: Download Image Assets Locally

# Create directory for pattern/paragraph assets
mkdir -p {theme-path}/assets/images/patterns

# Download each image asset
cd {theme-path}/assets/images/patterns
curl -o {descriptive-filename}.png "{figma-asset-url}"
curl -o {descriptive-filename-2}.jpg "{figma-asset-url-2}"

Update code references to use local paths:

OLD: src="https://www.figma.com/api/mcp/asset/..."
NEW: src="<?php echo esc_url( get_template_directory_uri() . '/assets/images/patterns/{filename}.png' ); ?>"

For Screenshot/Image Files:

STEP 1: Read Image File

Use Read tool to load the image:
Read(file_path: {screenshot-path})

STEP 2: Visual Analysis

Analyze the image visually:

• Identify layout structure
• Estimate colors (use hex color picker if available)
• Measure relative spacing and proportions
• Identify typography styles
• Note component hierarchy

DO NOT PROCEED until you have:

• ✅ Fetched Figma design (if Figma URL) OR loaded screenshot
• ✅ Extracted exact design values (colors, typography, spacing)
• ✅ Downloaded all image assets to local paths
• ✅ Have visual reference for comparison

1. Initial Assessment

Ask clarifying questions:

What type of component is this?
- WordPress block pattern?
- Drupal paragraph type?
- Custom theme component?

What's the primary purpose?
- Hero section?
- Content display?
- Interactive element?
- Navigation?

2. Visual Hierarchy Analysis

Examine and document:

Layout Structure:
- Sections and their relationships
- Container widths (full-width, contained, etc.)
- Visual hierarchy (what's most prominent)

Content Elements:
- Headings (identify h1, h2, h3 levels)
- Body text and captions
- Images and media placement
- Buttons and CTAs
- Icons and decorative elements

3. Component Mapping

For WordPress:

Map to Core Blocks:
- Group: Container/wrapper
- Cover: Full-width sections with background images
- Heading: H1-H6 headings
- Paragraph: Body text
- Buttons/Button: CTAs
- Image: Individual images
- Gallery: Image collections
- Columns/Column: Multi-column layouts
- Spacer: Vertical spacing
- Separator: Dividers

For Drupal:

Map to Paragraph Fields:
- Text (plain): Short text fields
- Text (formatted, long): Body/description fields
- Link: CTA buttons, navigation
- Entity reference (Media): Images, videos
- Boolean: Toggle features
- List (text): Select options
- Entity reference (Taxonomy): Categories/tags

4. Responsive Behavior Planning

Determine how layout changes:

Mobile (320px-767px):
- Single column layouts
- Stacked elements
- Larger touch targets
- Simplified navigation

Tablet (768px-1023px):
- 2-column layouts where appropriate
- Adjusted typography
- Moderate spacing

Desktop (1024px+):
- Multi-column layouts
- Full typography scale
- Maximum spacing
- Hover states prominent

5. Styling Requirements

Extract specific values:

Colors:
  primary: #HEXCODE
  secondary: #HEXCODE
  text: #HEXCODE
  background: #HEXCODE

Typography:
  heading-1: [size]px / [line-height] / [weight]
  heading-2: [size]px / [line-height] / [weight]
  body: [size]px / [line-height] / [weight]

Spacing:
  section-padding: [value]
  element-margin: [value]
  gap: [value]

6. Accessibility Requirements

Identify needs:

Semantic Structure:
- Proper heading hierarchy
- Landmark regions
- Form labels
- Button text

ARIA Needs:
- Labels for icon-only buttons
- Descriptions for complex widgets
- Live regions for dynamic content
- Hidden content for screen readers

Contrast:
- Check all text against backgrounds
- Verify minimum 4.5:1 for body text
- Verify minimum 3:1 for large text/UI

7. Interactive Elements

Document behavior:

For each interactive element:
- What triggers it (click, hover, focus)
- What changes (visual, content, navigation)
- Animation/transition details
- Keyboard interaction requirements
- Accessible alternatives

Output Format

Best Practices

1. ALWAYS Fetch Design Data First: Never analyze without fetching actual design using Figma MCP or Read tool
2. Use Exact Values from Figma: When Figma URL provided, use exact px/rem values from Figma data, not estimates
3. Download Assets Locally: Never reference Figma CDN URLs in production code - download to theme/module
4. Ask Before Assuming: If design intent is unclear, ask the user
5. Be Specific: Provide exact values (px, rem, hex codes)
6. Think Mobile-First: Always consider mobile layout first
7. Check Accessibility: Flag potential issues early
8. Document Interactions: Don't overlook hover states and animations
9. Map to Native Components: Prefer platform-native solutions

Common Patterns Recognition

Learn to quickly identify these patterns:

• Hero: Full-width section, background image, overlaid text, CTA
• Card Grid: Repeating items, image + text, equal heights
• CTA Banner: Contrasting background, centered text, prominent button
• Testimonial: Quote, author info, possibly image
• Slideshow: Multiple items, navigation arrows, pagination dots
• Feature List: Icons, headings, descriptions, grid/list layout
• Team Grid: Photos, names, titles, bio text

For each pattern, know the typical WordPress blocks or Drupal fields needed.
