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 | $0.00121 | $0.03104 |
| Opus 5 | $0.00060 | $0.01552 |
| Sonnet 5 | $0.00024 | $0.00621 |
| Haiku 4.5 | $0.00012 | $0.00310 |
Grade A, and why
threejs-core-scene-graph 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.

EventDispatcher |
Base class for ALL 3D objects. Provides transform, hierarchy, traversal |
Scene |
Object3D |
Root container. Adds background, environment, fog, overrideMaterial |
Group |
Object3D |
Semantic container with no extra functionality. Use for logical grouping |
Mesh |
Object3D |
Geometry + Material. The primary visible object in a scene |
Camera |
Object3D |
View projection. ALWAYS add to scene for matrix updates |
Light |
Object3D |
Illumination. ALWAYS add to scene for rendering |

quaternion |
Quaternion |
(0,0,0,1) |
Local rotation as quaternion. Linked to rotation |
scale |

type |
string |
Read-only class name (e.g., "Mesh", "Group") |
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-scene-graph 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 121 tokens to every session and 3,104 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.
