gsap-scrolltrigger

gsap-scrolltrigger is a cursor rule for Cursor from taotao135791-bit/gsap-transform. It costs 0 tokens per session (270 once invoked), scanned A, original, MIT.

A reference for GSAP ScrollTrigger, which connects animations to page scrolling. It covers effects such as pinning sections, scrubbing animations, revealing groups of items, and cleaning them up.

In plain words
What is it for?
Use it to build scroll-linked animations, parallax effects, pinned sections, scrubbed timelines, batched reveals, and safe cleanup when pages or components change.
Why use it?
It provides rules for choosing scroll behavior, updating trigger positions after layout changes, supporting reduced-motion preferences, and preventing leftover triggers in single-page apps.

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

gsap-scrolltrigger 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 3d 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.

What it actually says

gsap-scrolltrigger

  • Register once: gsap.registerPlugin(ScrollTrigger).
  • Pick scrub OR toggleActions, not both.
  • Never put a ScrollTrigger on a tween that is a child of a timeline — put it on the timeline or a top-level tween.
  • Call ScrollTrigger.refresh() after DOM/layout changes that affect trigger positions.
  • Create ScrollTriggers in top-to-bottom page order, or set refreshPriority.
  • Under prefers-reduced-motion: reduce: do NOT use scrub or pin. Use toggleActions or skip motion.
  • Batch lists with ScrollTrigger.batch(".item", { onEnter, start }) for stagger reveals.
  • Cleanup on SPA route change / component unmount: st.kill() or use gsap.context() / useGSAP().

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.
