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

   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

   # 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

1. 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

1. Calculate fluid typography

Formula: clamp(min, preferred, max)

     /* 16px to 24px between 320px and 1200px viewport */
     font-size: clamp(1rem, 0.5rem + 2vw, 1.5rem);
     

Pre-calculated scales:

     --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

1. 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

   # 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:

     import './design-tokens.css';
     
     <button className="btn btn-primary">Click</button>
     

Tailwind Config:

     const tokens = require('./design-tokens.json');
     
     module.exports = {
       theme: {
         colors: tokens.colors,
         fontFamily: tokens.typography.fontFamily
       }
     };
     

styled-components:

     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
