cinematic-scroll

A web-building workflow for pages whose visuals change as the visitor scrolls, such as pinned sections, layered movement, and 3D effects.

In plain words
What is it for?
Use it for cinematic landing pages, product stories, editorial shopping pages, launch pages, and other scroll-driven sites.
Why use it?
It provides a defined approach for creating scroll-based motion without having to design the interaction structure from scratch.

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 341 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.
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

Build cinematic, scroll-driven websites with the cinematic-scroll skill — pinned chapter reveals, hero/multi-depth parallax, scroll-linked 3D tilt and camera moves, and environment-morphing backgrounds. From a single self-contained .html scroll section (Mode A) to a full Next.js release site with optional AI-generated visuals (Mode B). The motion grammar is the constant; the aesthetic is always the user's.

When this fires

Use it when the request is for a scroll-driven or "cinematic" site, pinned/sticky chapter sections, hero or multi-depth parallax, scroll-linked 3D tilt or camera moves, an environment/background-morphing layout, a product story page, an editorial commerce microsite, or a release/launch/drop page.

Trigger

Use cinematic-scroll to build a self-contained HTML pinned hero chapter for [YOUR BRAND].

Do this

Read the canonical contract before building — do not work from this pointer alone:

  1. Read SKILL.md (repo root) in full — the single source of truth for both Mode A and Mode B and the 5-phase pipeline.
  2. Pull deep references from references/ as needed: scroll-patterns.md, film-archetypes.md, performance-budget.md, mobile-motion.md.
  3. Enforce taste-guardrails.md on every output.

More copy-paste triggers: examples/PROMPTS.md.

Changes

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.
