oraculo-radiohead: Skill for Cursor

.cursor/skills/threejs-materials/SKILL.md

threejs-materials is a skill for Cursor from Kenyi001/oraculo-radiohead. It costs 40 tokens per session (3,511 once invoked), scanned A, a copy of threejs-materials, MIT.

A Three.js guide to materials, the settings that determine how 3D surfaces look when rendered. It covers basic, lighting-based, physically based, toon, depth, and shader materials.

In plain words
What is it for?
Use it to style meshes, create realistic or cartoon surfaces, apply textures, write custom shader materials, and inspect or optimize material behaviour.
Why use it?
It helps you choose and configure the right surface model instead of trying material types without knowing how they handle lighting, reflections, or transparency.

Skill for Cursor

Written for Cursor: installed under .cursor/.

This is Kenyi001/oraculo-radiohead's own configuration. It tells Cursor how to work on oraculo-radiohead 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 oraculo-radiohead configures →

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

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 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.

Origin

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.
