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 | $0.00040 | $0.03511 |
| Opus 5.5 | $0.00016 | $0.01404 |
| Sonnet 5.5 | $0.00008 | $0.00702 |
| Haiku 4.5 | $0.00004 | $0.00351 |
Grade A, and why
threejs-materials 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.
This is a copy
94% identical to threejs-materials — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Three.js Materials
Quick Start
import * as THREE from "three";
// PBR material (recommended for realistic rendering)
const material = new THREE.MeshStandardMaterial({
color: 0x00ff00,
roughness: 0.5,
metalness: 0.5,
});
const mesh = new THREE.Mesh(geometry, material);
Material Types Overview
| Material | Use Case | Lighting |
|---|---|---|
| MeshBasicMaterial | Unlit, flat colors, wireframes | No |
| MeshLambertMaterial | Matte surfaces, performance | Yes (diffuse only) |
| MeshPhongMaterial | Shiny surfaces, specular highlights | Yes |
| MeshStandardMaterial | PBR, realistic materials | Yes (PBR) |
| MeshPhysicalMaterial | Advanced PBR, clearcoat, transmission | Yes (PBR+) |
| MeshToonMaterial | Cel-shaded, cartoon look | Yes (toon) |
| MeshNormalMaterial | Debug normals | No |
| MeshDepthMaterial | Depth visualization | No |
| ShaderMaterial | Custom GLSL shaders | Custom |
| RawShaderMaterial | Full shader control | Custom |
MeshBasicMaterial
No lighting calculations. Fast, always visible.
const material = new THREE.MeshBasicMaterial({
color: 0xff0000,
transparent: true,
opacity: 0.5,
side: THREE.DoubleSide, // FrontSide, BackSide, DoubleSide
wireframe: false,
map: texture, // Color/diffuse texture
alphaMap: alphaTexture, // Transparency texture
envMap: envTexture, // Reflection texture
reflectivity: 1, // Env map intensity
fog: true, // Affected by scene fog
});
MeshLambertMaterial
Diffuse-only lighting. Fast, no specular highlights.
const material = new THREE.MeshLambertMaterial({
color: 0x00ff00,
emissive: 0x111111, // Self-illumination color
emissiveIntensity: 1,
map: texture,
emissiveMap: emissiveTexture,
envMap: envTexture,
reflectivity: 0.5,
});
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-materials is a skill published in the GitHub repository GuitarAlchemist/ga (2 stars, last pushed yesterday), licensed MIT. It adds 40 tokens to every session and 3,511 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 94% identical to threejs-materials, differing in 3 lines, and is treated as a copy.
