Frontend Design System

This is a skill for production-grade UI design. It supports consistent and scalable frontend development through clear design tokens, layout rules, motion guidelines, and accessibility checks.

When to use this skill

• Production-quality UI needed: Generate high-quality UI from prompts
• Consistent design language: Consistent visual language across screens
• Typography/layout/motion guide: Systematic design system

Instructions

Step 1: Define Design Tokens

// design-tokens.ts
export const tokens = {
  // Colors
  colors: {
    primary: {
      50: '#EFF6FF',
      100: '#DBEAFE',
      500: '#3B82F6',
      600: '#2563EB',
      700: '#1D4ED8',
    },
    secondary: {
      500: '#6366F1',
      600: '#4F46E5',
    },
    accent: '#F59E0B',
    success: '#10B981',
    warning: '#F59E0B',
    error: '#EF4444',
    background: {
      primary: '#FFFFFF',
      secondary: '#F9FAFB',
      tertiary: '#F3F4F6',
    },
    text: {
      primary: '#1F2937',
      secondary: '#6B7280',
      tertiary: '#9CA3AF',
      inverse: '#FFFFFF',
    },
  },

  // Typography
  typography: {
    fontFamily: {
      sans: ['Inter', 'system-ui', 'sans-serif'],
      mono: ['JetBrains Mono', 'monospace'],
    },
    fontSize: {
      xs: '0.75rem',     // 12px
      sm: '0.875rem',    // 14px
      base: '1rem',      // 16px
      lg: '1.125rem',    // 18px
      xl: '1.25rem',     // 20px
      '2xl': '1.5rem',   // 24px
      '3xl': '1.875rem', // 30px
      '4xl': '2.25rem',  // 36px
    },
    fontWeight: {
      normal: 400,
      medium: 500,
      semibold: 600,
      bold: 700,
    },
    lineHeight: {
      tight: 1.25,
      normal: 1.5,
      relaxed: 1.75,
    },
  },

  // Spacing (8px base unit)
  spacing: {
    0: '0',
    1: '0.25rem',  // 4px
    2: '0.5rem',   // 8px
    3: '0.75rem',  // 12px
    4: '1rem',     // 16px
    5: '1.25rem',  // 20px
    6: '1.5rem',   // 24px
    8: '2rem',     // 32px
    10: '2.5rem',  // 40px
    12: '3rem',    // 48px
    16: '4rem',    // 64px
  },

  // Border Radius
  borderRadius: {
    none: '0',
    sm: '0.25rem',  // 4px
    md: '0.375rem', // 6px
    lg: '0.5rem',   // 8px
    xl: '0.75rem',  // 12px
    '2xl': '1rem',  // 16px
    full: '9999px',
  },

  // Shadows
  shadows: {
    sm: '0 1px 2px 0 rgb(0 0 0 / 0.05)',
    md: '0 4px 6px -1px rgb(0 0 0 / 0.1)',
    lg: '0 10px 15px -3px rgb(0 0 0 / 0.1)',
    xl: '0 20px 25px -5px rgb(0 0 0 / 0.1)',
  },

  // Breakpoints
  breakpoints: {
    sm: '640px',
    md: '768px',
    lg: '1024px',
    xl: '1280px',
    '2xl': '1536px',
  },
};

Step 2: Define Layout + UX Goals

page_spec:
  type: "landing" | "dashboard" | "form" | "blog" | "e-commerce"

  hierarchy:
    primary_action: [Primary CTA]
    secondary_actions: [secondary actions]
    information_architecture:
      - section: hero
        priority: 1
      - section: features
        priority: 2
      - section: social_proof
        priority: 3
      - section: cta
        priority: 4

  responsive:
    mobile_first: true
    breakpoints:
      - mobile: "< 640px"
      - tablet: "640px - 1024px"
      - desktop: "> 1024px"
    stack_behavior: "vertical on mobile, horizontal on desktop"

Step 3: Generate UI Output

Section-by-section component structure:

// Hero Section
<section className="hero">
  <div className="container">
    <div className="hero-content">
      <Badge>New Release</Badge>
      <Heading level

Prerequisites
Before installing skills in Cursor, ensure your development environment meets these requirements:
›Cursor installed and configured on your development machine
›Node.js version 16.0+ with npm package manager (verify with node --version)
›Active project directory or workspace where you want to add design-system
2
Execute installation command
Execute the skills CLI command in your project's root directory to begin installation:
$npx skills add https://github.com/supercent-io/skills-template --skill design-systemcopy
The skills CLI fetches design-system from GitHub repository supercent-io/skills-template and configures it for Cursor.

Security & Verification Notice
We perform automated surface-level scans (Gen AI Scanner, Socket, Snyk) during installation. These checks detect common vulnerabilities but do not guarantee complete security. Always review skill source code and verify the publisher's reputation before production use.
Skills execute code in your development environment. Always verify the publisher's identity, review recent commits, and test in isolated environments before production deployment.
