eIsland: Skill for Claude Code

.agents/skills/gsap-scrolltrigger/SKILL.md

gsap-scrolltrigger is a skill for Claude Code, Codex from JNTMTMTM/eIsland. It costs 68 tokens per session (4,484 once invoked), scanned A, original, GPL-3.0.

Guidance for GSAP ScrollTrigger, a web animation tool that links animation to page scrolling. It covers effects such as pinned sections, parallax movement, and scroll-controlled progress.

In plain words
What is it for?
Use it when building or recommending scrolling animations, parallax effects, pinned content, or other ScrollTrigger-based interactions.
Why use it?
It helps when ordinary animations need to respond to how far someone has scrolled or remain fixed during part of a page.

Which agent this was written for is unclear — body not stored (licence); the path alone says nothing. Also seen: installed under .agents/ (shared by several agents).

This is JNTMTMTM/eIsland's own configuration. It tells Claude Code and Codex how to work on eIsland itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything eIsland configures →

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 1mo 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 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.
