cinematic-scroll

cinematic-scroll is a skill for Codex from MustBeSimo/cinematic-scroll-skill. It costs 75 tokens per session (486 once invoked), scanned A, original, MIT.

A design and implementation guide for websites whose visual story changes as the visitor scrolls. It covers pinned sections, layered movement, depth effects, 3D tilting, and backgrounds that transform between scenes.

In plain words
What is it for?
Use it for cinematic landing pages, product stories, editorial sites, launches, and other pages with pinned chapters, parallax, or scroll-linked camera movement.
Why use it?
It provides a consistent way to plan scroll-based motion without treating each effect as an unrelated animation. It can guide anything from one HTML section to a complete Next.js site.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cinematic-scroll 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 yesterday.

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.

What it actually says

cinematic-scroll (pointer)

The cinematic-scroll skill gives an agent the taste to build cinematic, scroll-driven websites: pinned chapters, hero/multi-depth parallax, scroll-linked 3D tilt and camera moves, and environment-morphing backgrounds — from a single self-contained .html section (Mode A) to a full Next.js release site with optional AI-generated visuals (Mode B). Reach for it whenever the user asks for a scroll-driven or cinematic site, pinned/sticky sections, parallax, a product story page, an editorial microsite, or a release/launch/drop page.

Canonical instructions: ../../../SKILL.md — the single source of truth. Read it in full before building. This file is only a pointer; do not duplicate SKILL.md content.

Use the project's existing design system or adapt the bundled token contract: ../../../design.md + ../../../tokens/; 11 visual systems as machine themes in ../../../themes/.

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.
