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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00055 | $0.00317 |
| Opus 5 | $0.00028 | $0.00159 |
| Sonnet 5 | $0.00011 | $0.00063 |
| Haiku 4.5 | $0.00006 | $0.00032 |
Grade A, and why
gsap 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
GSAP animation skill (Forge)
Advanced, production-grade web animation with GSAP for Forge forge-website / frontend tasks.
This is a curated reference bundle (vendored from GreenSock's gsap-skills, MIT). Read the specific guide you need:
gsap-core/SKILL.md— core tween/timeline API and fundamentalsgsap-timeline/SKILL.md— sequencing with timelinesgsap-scrolltrigger/SKILL.md— scroll-driven animationgsap-react/SKILL.md— using GSAP in React (useGSAP)gsap-frameworks/SKILL.md— framework integration patternsgsap-plugins/SKILL.md— official pluginsgsap-performance/SKILL.md— compositor-friendly, jank-free motiongsap-utils/SKILL.md— utility methods and helpersllms.txt— full pinned reference index
Prefer compositor-friendly properties (transform/opacity), respect prefers-reduced-motion, and clean up
animations/ScrollTriggers on unmount. Keep motion purposeful — it should clarify flow, not distract.
What ships with it
9 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

gsap is a skill published in the GitHub repository ForgeyClap/claude-forge (2 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 317 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
