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);

Quick Start

**Generate tokens:**

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

**Validate usage:**

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

Component Spec Pattern

| Property | Default | Hover | Active | Disabled | |----------|---------|-------|--------|----------| | Background | primary | primary-dark | primary-darker | muted | | Text | white | white | white | muted-fg | | Border | none | none | none | muted-border | | Shadow | sm | md | none | none |

Scripts

| Script | Purpose | |--------|---------| | `generate-tokens.cjs` | Generate CSS from JSON token config | | `validate-tokens.cjs` | Check for hardcoded values in code | | `search-slides.py` | BM25 search + contextual recommendations | | `slide-token-validator.py` | Validate slide HTML for token compliance | | `fetch-background.py` | Fetch images from Pexels/Unsplash |

Templates

| Template | Purpose | |----------|---------| | `design-tokens-starter.json` | Starter JSON with three-layer structure |

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

| File | Purpose | |------|---------| | `docs/brand-guidelines.md` | Brand identity, voice, colors | | `assets/design-tokens.json` | Token definitions (primitive→semantic→component) | | `assets/design-tokens.css` | CSS variables (import in slides) | | `assets/css/slide-animations.css` | CSS animation library |

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

| File | Purpose | |------|---------| | `data/slide-strategies.csv` | 15 deck structures + emotion arcs + sparkline beats | | `data/slide-layouts.csv` | 25 layouts + component variants + animations | | `data/slide-layout-logic.csv` | Goal → Layout + break_pattern flag | | `data/slide-typography.csv` | Content type → Typography scale | | `data/slide-color-logic.csv` | Emotion → Color treatment | | `data/slide-backgrounds.csv` | Slide type → Image category (Pexels/Unsplash) | | `data/slide-copy.csv` | 25 copywriting formulas (PAS, AIDA, FAB) | | `data/slide-charts.csv` | 25 chart types with Chart.js config |

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
