What it does
Threejs is an agent skill from asgeirtj/system_prompts_leaks. Three.js 3D reference hub. Use when working with Three.js: pick the topic below and read its file for patterns and API guidance.
Its SKILL.md is about 370 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `references/threejs-animation.md`, `references/threejs-fundamentals.md` and `references/threejs-geometry.md`).
It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js. The repository describes itself as: Documented system prompts from Anthropic - Claude Fable 5.1, Opus 5.5, Claude Design, Claude Code. OpenAI - ChatGPT GPT-6-Astra, Codex. Google - Gemini 3.8 Flash, 3.1 Pro… The licence is MIT.
When your agent uses it
- Working with Three.js: pick the topic below and read its file for patterns and API guidance
- Tasks that involve 3D graphics and WebGL
Example prompts
- “/threejs”
What it can do on your machine
Read from SKILL.md and the folder at commit e31ec21. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Threejs loads about 374 tokens when it runs, and up to ~34k if it reads all its reference files. Until then it costs about 34 tokens; SKILL.md has 124 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
