Workflows
Workflow 1: Generate Design Tokens

Situation: You have a brand color and need a complete design token system.

Steps:

Identify brand color and style

Brand primary color (hex format)
Style preference: modern | classic | playful

Generate tokens using script

python scripts/design_token_generator.py "#0066CC" modern json


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

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


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:

Define component hierarchy

Atoms: Button, Input, Icon, Label, Badge
Molecules: FormField, SearchBar, Card, ListItem
Organisms: Header, Footer, DataTable, Modal
Templates: DashboardLayout, AuthLayout

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

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


Document component API

Props interface with types
Variant options
State handling (hover, active, focus, disabled)
Accessibility requirements

Reference: See references/component-architecture.md

Workflow 3: Responsive Design

Situation: You need breakpoints, fluid typography, or responsive spacing.

Steps:

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

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);


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

Reference: See references/responsive-calculations.md

Workflow 4: Developer Handoff

Situation: You need to hand off design tokens to development team.

Steps:

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


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']};
`;


Sync with Figma

Install Tokens Studio plugin
Import design-tokens.json
Tokens sync automatically with Figma styles

Handoff checklist

 Token files added to project
 Build pipeline configured
 Theme/CSS variables imported
 Component library aligned
 Documentation generated

Reference: See references/developer-handoff.md
