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 | $0.00126 | $0.00782 |
| Opus 5.5 | $0.00050 | $0.00313 |
| Sonnet 5.5 | $0.00025 | $0.00156 |
| Haiku 4.5 | $0.00013 | $0.00078 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 68 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Three.js (official LLM reference)
This skill vendors the official Three.js LLM documentation pack so the agent can generate correct modern three.js without inventing outdated CDN/r128 APIs.
Stack adaptation (this app builder)
You are in a TanStack Start + React workspace, not a bare HTML page:
| Official doc pattern | Do this here instead |
|---|---|
<script type="importmap"> + CDN three |
npm install three (+ @types/three if needed); import from "three" / "three/addons/…" |
| Raw HTML canvas bootstrap | Prefer @react-three/fiber + drei for games/UI integration (building-games + 3d-libs.md) |
Standalone WebGLRenderer demo |
Fine for a self-contained canvas module; still install three via npm so Vercel build has it |
| Always “latest” CDN version | Pin via package.json so dev and deploy match |
three is not preinstalled — add it with npm and leave it in package.json.
When to load what
- Game / interactive 3D product → start with
building-games(loop, controls, orientation, camera, first-run, steer sign). - R3F / drei / rapier wiring →
building-games/references/3d-libs.md. - Deep three API, TSL, WebGPU, materials, loaders, postprocessing → load
references/llms-full.txt(this skill’s full official dump).
Do not load llms-full.txt for simple 2D canvas games (Pong, tetris, etc.).
Full reference
Read on demand:
references/llms-full.txt
Source: https://threejs.org/docs/llms-full.txt (pinned copy for offline sandbox use).
Contents include: modern imports, WebGLRenderer vs WebGPURenderer, TSL complete reference, NodeMaterial, loaders, post-processing, compute, and API tables.
Quick defaults for this product
- Prefer WebGLRenderer (or R3F default) unless the user needs TSL/WebGPU compute.
- Cap pixel ratio (
renderer.setPixelRatio(Math.min(devicePixelRatio, 2))or R3Fdpr={[1,2]}). - Dispose geometries/materials/textures on teardown (three does not GC GPU resources).
- For games: still obey
building-gamescontrol and orientation self-tests.
What ships with it
1 file 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.
- 1mo ago First seen · 68 lines · 126 tokens per session scan A 0fadfe66cf78
threejs is a skill published in the GitHub repository ourobx/agent-ebpf (1 stars, last pushed 1mo ago), licensed MIT. It adds 126 tokens to every session and 782 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-09-04.
