Use for creating design systems, maintaining visual consistency, and facilitating design-dev collaboration. --- # UI Design System Generate design tokens, create color palettes, calculate typography scales, build component systems, and prepare developer handoff documentation. --- ## Table of Contents - [Trigger Terms](#trigger-terms) - [Workflows](#workflows) - [Workflow 1: Generate Design Tokens](#workflow-1-generate-design-tokens) - [Workflow 2: Create Component System](#workflow-2-create-component-system) - [Workflow 3: Responsive Design](#workflow-3-responsive-design) - [Workflow 4: Developer Handoff](#workflow-4-developer-handoff) - [Tool Reference](#tool-reference) - [Quick Reference Tables](#quick-reference-tables) - [Knowledge Base](#knowledge-base) --- ## Trigger Terms Use this skill when you need to: - "generate design tokens" - "create color palette" - "build typography scale" - "calculate spacing system" - "create design system" - "generate CSS variables" - "export SCSS tokens" - "set up component architecture" - "document component library" - "calculate responsive breakpoints" - "prepare developer handoff" - "convert brand color to palette" - "check WCAG contrast" - "build 8pt grid system" --- ## Workflows ### Workflow 1: Generate Design Tokens **Situation:** You have a brand color and need a complete design token system. **Steps:** 1. **Identify brand color and style** - Brand primary color (hex format) - Style preference: `modern` | `classic` | `playful` 2. **Generate tokens using script** ```bash python scripts/design_token_generator.py "#0066CC" modern json ``` 3. **Review generated categories** - Colors: primary, secondary, neutral, semantic, surface - Typography: fontFamily, fontSize, fontWeight, lineHeight - Spacing: 8pt grid-based scale (0-64) - Borders: radius, width - Shadows: none through 2xl - Animation: duration, easing - Breakpoints: xs through 2xl 4. **Export in target format** ```bash # CSS custom properties python scripts/design_token_generator.py "#0066CC" modern css > design-tokens.css # SCSS variables python scripts/design_token_generator.py "#0066CC" modern scss > _design-tokens.scss # JSON for Figma/tooling python scripts/design_token_generator.py "#0066CC" modern json > design-tokens.json ``` 5. **Validate accessibility** - Check color contrast meets WCAG AA (4.5:1 normal, 3:1 large text) - Verify semantic colors have contrast colors defined --- ### Workflow 2: Create Component System **Situation:** You need to structure a component library using design tokens. **Steps:** 1. **Define component hierarchy** - Atoms: Button, Input, Icon, Label, Badge - Molecules: FormField, SearchBar, Card, ListItem - Organisms: Header, Footer, DataTable, Modal - Templates: DashboardLayout, AuthLayout 2. **Map tokens to components** | Component | Tokens Used | |-----------|-------------| | Button | colors, sizing, borders, shadows, typography | | Input | colors, sizing, borders, spacing | | Card | colors, borders, shadows, spacing | | Modal | colors, shadows, spacing, z-index, animation | 3. **Define variant patterns** Size variants: ``` sm: height 32px, paddingX 12px, fontSize 14px md: height 40px, paddingX 16px, fontSize 16px lg: height 48px, paddingX 20px, fontSize 18px ``` Color variants: ``` primary: background primary-500, text white secondary: background neutral-100, text neutral-900 ghost: background transparent, text neutral-700 ``` 4. **Document component API** - Props interface with types - Variant options - State handling (hover, active, focus, disabled) - Accessibility requirements 5. **Reference:** See `references/component-architecture.md` --- ### Workflow 3: Responsive Design **Situation:** You need breakpoints, fluid typography, or responsive spacing. **Steps:** 1. **Define breakpoints** | Name | Width | Target | |------|-------|--------| | xs | 0 | Small phones | | sm | 480px | Large phones | | md | 640px | Tablets | | lg | 768px | Small laptops | | xl | 1024px | Desktops | | 2xl | 1280px | Large screens | 2. **Calculate fluid typography** Formula: `clamp(min, preferred, max)` ```css /* 16px to 24px between 320px and 1200px viewport */ font-size: clamp(1rem, 0.5rem + 2vw, 1.5rem); ``` Pre-calculated scales: ```css --fluid-h1: clamp(2rem, 1rem + 3.6vw, 4rem); --fluid-h2: clamp(1.75rem, 1rem + 2.3vw, 3rem); --fluid-h3: clamp(1.5rem, 1rem + 1.4vw, 2.25rem); --fluid-body: clamp(1rem, 0.95rem + 0.2vw, 1.125rem); ``` 3. **Set up responsive spacing** | Token | Mobile | Tablet | Desktop | |-------|--------|--------|---------| | --space-md | 12px | 16px | 16px | | --space-lg | 16px | 24px | 32px | | --space-xl | 24px | 32px | 48px | | --space-section | 48px | 80px | 120px | 4. **Reference:** See `references/responsive-calculations.md` --- ### Workflow 4: Developer Handoff **Situation:** You need to hand off design tokens to development team. **Steps:** 1. **Export tokens in required formats** ```bash # For CSS projects python scripts/design_token_generator.py "#0066CC" modern css # For SCSS projects python scripts/design_token_generator.py "#0066CC" modern scss # For JavaScript/TypeScript python scripts/design_token_generator.py "#0066CC" modern json ``` 2. **Prepare framework integration** **React + CSS Variables:** ```tsx import './design-tokens.css'; <button className="btn btn-primary">Click</button> ``` **Tailwind Config:** ```javascript const tokens = require('./design-tokens.json'); module.exports = { theme: { colors: tokens.colors, fontFamily: tokens.typography.fontFamily } }; ``` **styled-components:** ```typescript import tokens from './design-tokens.json'; const Button = styled.button` background: ${tokens.colors.primary['500']}; padding: ${tokens.spacing['2']} ${tokens.spacing['4']}; `; ``` 3. **Sync with Figma** - Install Tokens Studio plugin - Import design-tokens.json - Tokens sync automatically with Figma styles 4. **Handoff checklist** - [ ] Token files added to project - [ ] Build pipeline configured - [ ] Theme/CSS variables imported - [ ] Component library aligned - [ ] Documentation generated 5. **Reference:** See `references/developer-handoff.md` --- ## Tool Reference ### design_token_generator.py Generates complete design token system from brand color. | Argument | Values | Default | Description | |----------|--------|---------|-------------| | brand_color | Hex color | #0066CC | Primary brand color | | style | modern, classic, playful | modern | Design style preset | | format | json, css, scss, summary | json | Output format | **Examples:** ```bash # Generate JSON tokens (default) python scripts/design_token_generator.py "#0066CC" # Classic style with CSS output python scripts/design_token_generator.py "#8B4513" classic css # Playful style summary view python scripts/design_token_generator.py "#FF6B6B" playful summary ``` **Output Categories:** | Category | Description | Key Values | |----------|-------------|------------| | colors | Color palettes | primary, secondary, neutral, semantic, surface | | typography | Font system | fontFamily, fontSize, fontWeight, lineHeight | | spacing | 8pt grid | 0-64 scale, semantic (xs-3xl) | | sizing | Component sizes | container, button, input, icon | | borders | Border values | radius (per style), width | | shadows | Shadow styles | none through 2xl, inner | | animation | Motion tokens | duration, easing, keyframes | | breakpoints | Responsive | xs, sm, md, lg, xl, 2xl | | z-index | Layer system | base through notification | --- ## Quick Reference Tables ### Color Scale Generation | Step | Brightness | Saturation | Use Case | |------|------------|------------|----------| | 50 | 95% fixed | 30% | Subtle backgrounds | | 100 | 95% fixed | 38% | Light backgrounds | | 200 | 95% fixed | 46% | Hover states | | 300 | 95% fixed | 54% | Borders | | 400 | 95% fixed | 62% | Disabled states | | 500 | Original | 70% | Base/default color | | 600 | Original × 0.8 | 78% | Hover (dark) | | 700 | Original × 0.6 | 86% | Active states | | 800 | Original × 0.4 | 94% | Text | | 900 | Original × 0.2 | 100% | Headings | ### Typography Scale (1.25x Ratio) | Size | Value | Calculation | |------|-------|-------------| | xs | 10px | 16 ÷ 1.25² | | sm | 13px | 16 ÷ 1.25¹ | | base | 16px | Base | | lg | 20px | 16 × 1.25¹ | | xl | 25px | 16 × 1.25² | | 2xl | 31px | 16 × 1.25³ | | 3xl | 39px | 16 × 1.25⁴ | | 4xl | 49px | 16 × 1.25⁵ | | 5xl | 61px | 16 × 1.25⁶ | ### WCAG Contrast Requirements | Level | Normal Text | Large Text | |-------|-------------|------------| | AA | 4.5:1 | 3:1 | | AAA | 7:1 | 4.5:1 | Large text: ≥18pt regular or ≥14pt bold ### Style Presets | Aspect | Modern | Classic | Playful | |--------|--------|---------|---------| | Font Sans | Inter | Helvetica | Poppins | | Font Mono | Fira Code | Courier | Source Code Pro | | Radius Default | 8px | 4px | 16px | | Shadows | Layered, subtle | Single layer | Soft, pronounced | --- ## Knowledge Base Detailed reference guides in `references/`: | File | Content | |------|---------| | `token-generation.md` | Color algorithms, HSV space, WCAG contrast, type scales | | `component-architecture.md` | Atomic design, naming conventions, props patterns | | `responsive-calculations.md` | Breakpoints, fluid typography, grid systems | | `developer-handoff.md` | Export formats, framework setup, Figma sync | --- ## Validation Checklist ### Token Generation - [ ] Brand color provided in hex format - [ ] Style matches project requirements - [ ] All token categories generated - [ ] Semantic colors include contrast values ### Component System - [ ] All sizes implemented (sm, md, lg) - [ ] All variants implemented (primary, secondary, ghost) - [ ] All states working (hover, active, focus, disabled) - [ ] Uses only design tokens (no hardcoded values) ### Accessibility - [ ] Color contrast meets WCAG AA - [ ] Focus indicators visible - [ ] Touch targets ≥ 44×44px - [ ] Semantic HTML elements used ### Developer Handoff - [ ] Tokens exported in required format - [ ] Framework integration documented - [ ] Design tool synced - [ ] Component documentation complete
