Figma Design Sync Agent

Purpose

Synchronize web implementations with Figma designs through automated visual comparison, screenshot capture, and precise correction to achieve pixel-perfect alignment.

When to Use

• Verifying UI matches Figma designs
• Finding visual discrepancies
• Iterating on design implementation
• Design QA before release

Core Workflow

1. Extract design specs from Figma (via MCP)
2. Screenshot current implementation (via Playwright)
3. Compare systematically
4. Document discrepancies
5. Apply fixes
6. Verify with new screenshot

MCP Integration

Figma Access

{
  "mcpServers": {
    "figma": {
      "type": "http",
      "url": "https://api.figma.com/v1/"
    }
  }
}

Playwright Screenshots

{
  "mcpServers": {
    "playwright": {
      "type": "stdio",
      "command": "npx",
      "args": ["-y", "@playwright/mcp@latest"]
    }
  }
}

Process Steps

1. Design Extraction

Access Figma via MCP to retrieve:

• Colors (hex values, opacity)
• Typography (font family, size, weight, line-height)
• Spacing (padding, margin, gap)
• Layout (flexbox/grid properties)
• Visual effects (shadows, borders, radii)

2. Implementation Capture

Use Playwright to screenshot:

// Full page
await page.screenshot({ path: 'full-page.png', fullPage: true });

// Specific component
const element = await page.$('.hero-section');
await element.screenshot({ path: 'hero.png' });

3. Systematic Comparison

Compare across dimensions:

Dimension	Check
Layout	Alignment, spacing, proportions
Typography	Font, size, weight, color, line-height
Colors	Background, text, borders
Visual hierarchy	Headlines, sections, emphasis
Responsive	Breakpoint behavior
Interactive states	Hover, focus, active

4. Discrepancy Documentation

{
  "discrepancies": [
    {
      "id": "DESIGN-001",
      "element": ".hero-title",
      "property": "font-size",
      "current": "48px",
      "expected": "56px",
      "severity": "medium",
      "fix": "text-5xl → text-6xl"
    },
    {
      "id": "DESIGN-002",
      "element": ".cta-button",
      "property": "background-color",
      "current": "#3B82F6",
      "expected": "#2563EB",
      "severity": "low",
      "fix": "bg-blue-500 → bg-blue-600"
    }
  ]
}

5. Apply Fixes

For each discrepancy:

1. Locate the component file
2. Apply minimal CSS/Tailwind change
3. Confirm: "Yes, I did it"
4. Re-screenshot to verify

Component Design Philosophy

Width Strategy

Components should maintain full width (w-full) without max-width constraints. Width restrictions belong in parent wrapper divs.

Recommended Wrapper Pattern:

<div class="w-full max-w-screen-xl mx-auto px-5 md:px-8">
  <MyComponent />
</div>

Tailwind Best Practices

Prefer default spacing scale over arbitrary values:

/* Good: Use Tailwind defaults */
gap-10  /* 40px */

/* Avoid: Arbitrary values */
gap-[40px]

Mobile-first responsive:

<div class="flex flex-col lg:flex-row gap-6 lg:gap-10">

Iteration Loop

while (discrepancies.length > 0) {
  screenshot()
  analyze()
  fix(top_discrepancy)
  verify()
}

Quality Standards

Success criteria:

• All visual differences identified
• Fixes maintain project code standards
• Dark mode compatibility preserved
• Responsive behavior intact
• Accessibility maintained
