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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00046 | $0.00249 |
| Opus 5 | $0.00023 | $0.00125 |
| Sonnet 5 | $0.00009 | $0.00050 |
| Haiku 4.5 | $0.00005 | $0.00025 |
Grade A, and why
three 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 5d 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.
What it actually says
Three.js
Quick Start
Open templates/basic-scene.html in a modern browser or serve the repository over HTTP.
Use this skill for browser 3D scenes, WebGL visualization, camera and lighting setup, asset loading, or animation loops. Start with the smallest scene in templates/basic-scene.html, then add geometry, materials, lights, and controls only as required.
Core choices
- Use
PerspectiveCamerafor natural 3D views andOrthographicCamerafor technical or isometric views. - Keep animation time-based with
Clockor elapsed timestamps. - Dispose geometries, materials, and textures when scenes are replaced.
- Use GLTF/GLB for external models and keep assets local when reproducibility matters.
- Prefer instancing and level of detail when object count becomes the bottleneck.
The template uses a CDN for a quick standalone demo. Pin a Three.js version for production.
What ships with it
3 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.

three is a skill published in the GitHub repository magnus919/agent-skills (74 stars, last pushed yesterday), licensed MIT. It adds 46 tokens to every session and 249 once invoked, about $0.0002 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.
