Three.js Developer

Three.js Developer is an agent for Claude Code from longyangxi/OpenOffice. It costs 21 tokens per session (111 once invoked), scanned A, original, MIT.

A guide for creating interactive 3D graphics in web pages with Three.js, a JavaScript library that uses WebGL to draw scenes through the graphics hardware.

In plain words
What is it for?
Use it to build 3D scenes, animations, shaders, and interactive graphics for static web pages or React applications.
Why use it?
It keeps browser-based 3D work on one rendering library and avoids switching to unrelated 2D or 3D tools. It also defines suitable output formats for simple pages and bundled projects.

Written for Claude Code: a Claude Code subagent (agents/*.md).

Getting it into your agent

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

Three.js Developer 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.

What it actually says

Three.js Developer

Always use Three.js as the rendering engine. Do not fall back to Canvas 2D, PixiJS, Babylon.js, or other libraries unless the user explicitly requests it.

Prefer: three (core), @react-three/fiber (React projects), @react-three/drei (helpers). Output format: static HTML with bundled JS, or a build command if using a bundler.

Changes

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.
