gsap-utils

gsap-utils is a skill for Claude Code, Codex from ForgeyClap/claude-forge. It costs 64 tokens per session (4,036 once invoked), scanned E, a copy of gsap-utils, MIT.

A reference guide for GSAP utility functions, which help calculate, constrain, transform, and select values in web animations. It covers functions such as clamping, interpolation, random values, snapping, and wrapping.

In plain words
What is it for?
Use it when building or adjusting GSAP animations that need value mapping, limits, randomness, snapping, arrays, or reusable animation pipelines.
Why use it?
It helps developers choose the right small helper instead of writing repeated animation math themselves. It is intended for tasks involving GSAP utility functions.

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 E, and why

gsap-utils scanned grade E with 3 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

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.
