Scroll Storyteller
Create immersive, interactive storytelling experiences using Anthropic's authentic design language: strict duotone palette, organic Bézier SVG paths, custom cursors, and chapter-based narratives.
Workflow
Use AskUserQuestion to gather preferences, then generate:
| Step | Question | Options |
|---|
| 1 | Animation? | GSAP (rich) vs CSS-only (lightweight) |
| 2 | Mood? | Warm vs Cool vs Creative |
| 3 | Palette? | (show 3-4 based on mood) |
| 4 | Topic? | Biblical/Tech/Business/Personal/Custom |
| 5 | Chapters? | 3, 4, or 5 |
| 6 | Content per chapter | Title, description, keywords |
Generate:
bash ~/.claude/skills/scroll-storyteller/scripts/generate.sh my-story <palette> [--gsap] [--chapters N]
Post-generation: Customize content, create SVGs (see references/structure-templates.md)
SVG Illustration Workflow
Each chapter needs a topic-relevant SVG that matches the narrative position:
| Position | Purpose | Composition | Example |
|---|
| Hero | Set scene, show contrast | Wide (1000x1000), 2 silhouettes | David vs Goliath distant |
| Chapter 1 | Introduce protagonist | Centered figure + context | Shepherd with sheep |
| Chapter 2 | Show conflict/obstacle | Imposing, fills frame | Giant warrior |
| Chapter 3 | Resolution/triumph | Dynamic, radiating | Victor + fallen + rays |
| Chapter 4 | Deepening conflict (optional) | Crowded, escalating | Army masses, threats multiply |
| Chapter 5 | Final climax (optional) |
Light/Dark Pattern by Chapter Count:
- 3 chapters: Ch1=Light → Ch2=Dark → Ch3=Light
- 4 chapters: Ch1=Light → Ch2=Dark → Ch3=Light → Ch4=Dark
- 5 chapters: Ch1=Light → Ch2=Dark → Ch3=Light → Ch4=Dark → Ch5=Light
Process:
- Load
references/svg-illustration-guide.md for theme → element mapping
- Identify chapter position (hero/ch1/ch2/ch3/ch4/ch5/finale)
- Extract topic keywords from chapter content
- Select SVG elements from element library:
- Characters: figure-small, figure-large, figure-triumphant, figure-action
- Nature: hills, sun, tree, path, clouds, lightning, wind
- Objects: staff, crown, shield, weapon, stone, obstacle
- Abstract: radiate, rings, trajectory, converge, impact
- Compose using position template
- Apply palette mood style (see
references/design-harmony.md → Palette Mood → SVG Style)
- Add animation classes:
organic-path, fade-path, scale-path
SVG Checklist:
- Uses only
var(--deep) and var(--foam) colors
- All paths are organic Bézier curves (Q/C commands)
- No geometric primitives (circle, rect, ellipse)
- Opacity range matches palette mood
- Composition matches chapter position
- Symbolically represents chapter content
Animation Styles
| Style | Library | Size | Best For |
|---|
| GSAP | GSAP 3.x + ScrollTrigger | ~45KB | Rich interactions, SVG draw, orbits, timelines |

CSS-only Features
- IntersectionObserver reveals
- CSS transitions with delays
- Transform-based animations

Anthropic Design Language
Strict Duotone Palette
| Element | Hex | CSS Variable |
|---|
| Cream (light) | #FAF9F5 | --cream |
| Charcoal (dark) | #141413 | --charcoal |
Rule: No other colors. All illustrations use exactly these two.
Typography
| Role | Font | Fallback |
|---|
| Display/Headings | Instrument Serif | Georgia, serif |
| Body/UI | Inter | -apple-system, sans-serif |
Characteristics:
- Large, editorial headings (clamp 3rem - 7rem)
- Light weight (300-400)
- Negative letter-spacing on display (-0.02em)
- Generous line-height (1.5-1.8)
SVG Design Rules
| Rule | Description |
|---|
| Fills only | Never use strokes for main shapes |
| Organic paths | Complex Bézier curves, hand-drawn feel |
| viewBox | Always 1000x1000 or 500x500 (square) |
| 2-4 paths | Keep compositions simple |
| Layered | Light shapes behind, dark in front |
Anti-patterns:
❌ <circle>, <rect>, <ellipse> (geometric)
❌ stroke="..." on main elements
❌ Multiple colors
✅ <path d="M... Q... C..."> with organic curves
Topic-Driven SVG Generation
The svg-generator.sh helper automatically selects appropriate SVG templates based on chapter content:
| Keywords | Template | Best For |
|---|
| identity, profile, self, unique | Fingerprint + Verification | Personal identity concepts |
| network, connect, distributed, system | Central Hub + Network | System architecture concepts |
| protect, secure, vault, lock | Protected Vault + Links | Security concepts |
| growth, learn, knowledge, tree | Knowledge Tree | Learning/growth concepts |
| enforce, filter, gate, barrier | Gateway Arches | Enforcement/validation |
| trust, hand, collaboration | Hand Holding + Connection | Partnership concepts |
| unify, finale, complete | Concentric Symbol | Conclusion/unity |
Usage:
# Source the generator in your script
source scripts/svg-generator.sh
# Generate SVG for a chapter (position: hero/ch1/ch2/ch3/ch4/ch5/finale)
generate_svg_for_chapter \
"ch1" \
"Digital Identity" \
"Your unique identity on the blockchain" \
"var(--foam)" \
"var(--deep)" \
"fade-path"
Positions: hero | ch1 | ch2 | ch3 | ch4 | ch5 | finale
