Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00106 | $0.02582 |
| Opus 5 | $0.00053 | $0.01291 |
| Sonnet 5 | $0.00021 | $0.00516 |
| Haiku 4.5 | $0.00011 | $0.00258 |
Grade A, and why
scroll-world-storytelling scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to scroll-world-storytelling — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 242 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Scroll World Storytelling
Turn source material into one connected journey. Scroll advances a visual world and the copy reveals the story in deliberate beats.
The skill has exactly three production modes. Choose one primary mode before building:
- Video scrub — generated or filmed footage, mapped to scroll.
- Three.js world — a real-time 3D object, place, planet, or system.
- HTML / data / type — semantic DOM, SVG charts, metrics, and kinetic typography.
Do not mix modes by default. A focused renderer produces a clearer concept, smaller test surface, and more reliable fallback.
Start with the contract
Write these blocks before implementation.
Goal
Turn the supplied story into a one-page journey with 5–7 memorable beats and one final action. A first-time visitor should understand the thesis, tension, mechanism, proof, and payoff without reading the source.
House rules
- Preserve the source thesis, sequence, facts, and caveats. Never invent proof.
- Use one connected world, one dominant motion grammar, and one art direction.
- Let motion carry transitions; let copy explain meaning.
- Keep one primary CTA. Keep navigation and utility controls quiet.
- Keep native, reversible document scrolling. Never hijack the wheel.
- Never spend generation credits, publish, deploy, or replace production files without approval.
- Keep builder and verifier separate when agents are available.
Bar
- A visitor can explain the arc after one pass.
- Scrolling works forward, backward, slowly, and with a fast flick.
- No visible jump, flash, or unintended reversal at a seam.
- The page remains legible on mobile and with reduced motion.
- Every completion claim includes browser, console, responsive, and asset evidence.
Read the whole source
- Read the complete article or narrative.
- Inspect the target repo, framework, asset pipeline, and current page.
- Separate source facts from presentation ideas.
- Collect supplied brand assets and 2–3 references when available.
- Identify the one action the story should earn.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scroll-world-storytelling is a skill published in the GitHub repository devinilabs/pro-skill (24 stars, last pushed 26d ago), licensed MIT. It adds 106 tokens to every session and 2,582 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to scroll-world-storytelling, differing in 0 lines, and is treated as a copy.
