Design System

Token architecture, component specifications, systematic design, slide generation.

When to Use

• Design token creation
• Component state definitions
• CSS variable systems
• Spacing/typography scales
• Design-to-code handoff
• Tailwind theme configuration
• Slide/presentation generation

Token Architecture

Load: references/token-architecture.md

Three-Layer Structure

Primitive (raw values)
       ↓
Semantic (purpose aliases)
       ↓
Component (component-specific)

Example:

/* Primitive */
--color-blue-600: #2563EB;

/* Semantic */
--color-primary: var(--color-blue-600);

/* Component */
--button-bg: var(--color-primary);

Script Paths

Script paths in this skill and its references/ are relative to the directory that contains this SKILL.md, not to the project: scripts/<file> is this skill's own scripts/ folder, and ../<skill>/scripts/<file> is a sibling sub-skill installed alongside it. Build the full path from that directory (Claude Code reports it as the skill's base directory when the skill loads) and keep the working directory at the project root — the scripts read and write project files such as docs/brand-guidelines.md, assets/design-tokens.json or src/ relative to it.

Quick Start

Generate tokens:

node scripts/generate-tokens.cjs --config tokens.json -o tokens.css

Validate usage:

node scripts/validate-tokens.cjs --dir src/

Integration

With brand: Extract primitives from brand colors/typography

With ui-styling: Component tokens → Tailwind config

Skill Dependencies: brand, ui-styling

Primary Agents: ui-ux-designer, frontend-developer

Slide System

Brand-compliant presentations using design tokens + Chart.js + contextual decision system.

Source of Truth

Slide Search (BM25)

# Basic search (auto-detect domain)
python scripts/search-slides.py "investor pitch"

# Domain-specific search
python scripts/search-slides.py "problem agitation" -d copy
python scripts/search-slides.py "revenue growth" -d chart

# Contextual search (Premium System)
python scripts/search-slides.py "problem slide" --context --position 2 --total 9
python scripts/search-slides.py "cta" --context --position 9 --prev-emotion frustration

Decision System CSVs

Contextual Decision Flow

1. Parse goal/context
        ↓
2. Search slide-strategies.csv → Get strategy + emotion beats
        ↓
3. For each slide:
   a. Query slide-layout-logic.csv → layout + break_pattern
   b. Query slide-typography.csv → type scale
   c. Query slide-color-logic.csv → color treatment
   d. Query slide-backgrounds.csv → image if needed
   e. Apply animation class from slide-animations.css
        ↓
4. Generate HTML with design tokens
        ↓
5. Validate with slide-token-validator.py

Pattern Breaking (Duarte Sparkline)

Premium decks alternate between emotions for engagement:

"What Is" (frustration) ↔ "What Could Be" (hope)

System calculates pattern breaks at 1/3 and 2/3 positions.

Slide Requirements

ALL slides MUST:

1. Import assets/design-tokens.css - single source of truth
2. Use CSS variables: var(--color-primary), var(--slide-bg), etc.
3. Use Chart.js for charts (NOT CSS-only bars)
4. Include navigation (keyboard arrows, click, progress bar)
5. Center align content
6. Focus on persuasion/conversion

Chart.js Integration

<script src="https://cdn.jsdelivr.net/npm/chart.js@4.4.1/dist/chart.umd.min.js"></script>

<canvas id="revenueChart"></canvas>
<script>
new Chart(document.getElementById('revenueChart'), {
    type: 'line',
    data: {
        labels: ['Sep', 'Oct', 'Nov', 'Dec'],
        datasets: [{
            data: [5, 12, 28, 45],
            borderColor: '#FF6B6B',  // Use brand coral
            backgroundColor: 'rgba(255, 107, 107, 0.1)',
            fill: true,
            tension: 0.4
        }]
    }
});
</script>

Token Compliance

/* CORRECT - uses token */
background: var(--slide-bg);
color: var(--color-primary);
font-family: var(--typography-font-heading);

/* WRONG - hardcoded */
background: #0D0D0D;
color: #FF6B6B;
font-family: 'Space Grotesk';

Reference Implementation

Working example with all features:

assets/designs/slides/claudekit-pitch-251223.html

Command

/slides:create "10-slide investor pitch for ClaudeKit Marketing"

Best Practices

1. Never use raw hex in components - always reference tokens
2. Semantic layer enables theme switching (light/dark)
3. Component tokens enable per-component customization
4. Use HSL format for opacity control
5. Document every token's purpose
6. Slides must import design-tokens.css and use var() exclusively
