threejs

threejs is a skill for Claude Code, Codex from ihatesea69/kiro-kit. It costs 136 tokens per session (1,019 once invoked), scanned A, original, MIT.

A guide for building interactive 3D graphics in web browsers with Three.js, a JavaScript library for rendering scenes, models, lighting, animation, and effects.

In plain words
What is it for?
Use it to create 3D visualizations, games, product configurators, simulations, and VR or augmented-reality experiences on the web.
Why use it?
It helps you work through the many parts of browser-based 3D without having to piece together the relevant Three.js techniques yourself.

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 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.

Three.js Development

Build high-performance 3D web applications using Three.js - a cross-browser WebGL/WebGPU library.

When to Use This Skill

Use when working with:

  • 3D scenes, models, animations, or visualizations
  • WebGL/WebGPU rendering and graphics programming
  • Interactive 3D experiences (games, configurators, data viz)
  • Camera controls, lighting, materials, or shaders
  • Loading 3D assets (GLTF, FBX, OBJ) or textures
  • Post-processing effects (bloom, depth of field, SSAO)
  • Physics simulations, VR/XR experiences, or spatial audio
  • Performance optimization (instancing, LOD, frustum culling)

Progressive Learning Path

Level 1: Getting Started

Load references/01-getting-started.md - Scene setup, basic geometries, materials, lights, rendering loop

Level 2: Common Tasks

  • Textures: references/03-textures.md - Types, mapping, wrapping, filtering
  • Cameras: references/04-cameras.md - Perspective, orthographic, controls
  • Lights: references/05-lights.md - Types, shadows, helpers
  • Animations: references/06-animations.md - Clips, mixer, keyframes
  • Math: references/07-math.md - Vectors, matrices, quaternions, curves

Level 3: Interactive & Effects

  • Interaction: references/08-interaction.md - Raycasting, picking, transforms
  • Post-Processing: references/09-postprocessing.md - Passes, bloom, SSAO, SSR
  • Controls (Addons): references/10-controls.md - Orbit, transform, first-person

Level 4: Advanced Rendering

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 is a skill published in the GitHub repository ihatesea69/kiro-kit (18 stars, last pushed 16d ago), licensed MIT. It adds 136 tokens to every session and 1,019 once invoked, about $0.0007 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.
