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 5.1 | $0.00123 | $0.02771 |
| Opus 5 | $0.00062 | $0.01385 |
| Sonnet 5 | $0.00025 | $0.00554 |
| Haiku 4.5 | $0.00012 | $0.00277 |
Grade A, and why
threejs-core-renderer 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 9d 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.

Quick Reference
Standard Initialization Pattern
import {
WebGLRenderer, SRGBColorSpace, ACESFilmicToneMapping,
PCFSoftShadowMap, PerspectiveCamera, Scene
} from 'three';
const renderer = new WebGLRenderer({ antialias: true });
renderer.setSize(window.innerWidth, window.innerHeight);
renderer.setPixelRatio(Math.min(window.devicePixelRatio, 2));
renderer.outputColorSpace = SRGBColorSpace;
renderer.toneMapping = ACESFilmicToneMapping;
renderer.toneMappingExposure = 1.0;
renderer.shadowMap.enabled = true;
renderer.shadowMap.type = PCFSoftShadowMap;
document.body.appendChild(renderer.domElement);
const scene = new Scene();
const camera = new PerspectiveCamera(50, window.innerWidth / window.innerHeight, 0.1, 1000);
renderer.setAnimationLoop((time) => {
renderer.render(scene, camera);
});

What ships with it
4 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.

threejs-core-renderer is a skill published in the GitHub repository Impertio-Studio/Three.js-Claude-Skill-Package (13 stars, last pushed 2mo ago), licensed MIT. It adds 123 tokens to every session and 2,771 once invoked, about $0.0006 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 2026-08-30.
