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

gsap-plugins is a skill for Claude Code, Codex from JNTMTMTM/eIsland. It costs 91 tokens per session (5,648 once invoked), scanned A, original, GPL-3.0.

A reference guide for GSAP plugins, which add animation features to the GreenSock Animation Platform, a JavaScript library for moving and transforming elements.

In plain words
What is it for?
Use it for plugins that handle scrolling, draggable elements, flipping layouts, splitting text, SVG effects, custom easing, physics, and related animation tasks.
Why use it?
It helps you choose and use the right GSAP plugin when built-in animations are not enough.

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 →

SkillSpector: 1 finding, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Privilege Escalation · line 20
    Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.
    Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

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-plugins 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 8d 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.
