What it does
Threejs Builder is an agent skill from chongdashu/vibejam-starter-pack. Design and implement lightweight Three.js (r150+) ES-module scenes—hero sections, interactive product viewers, particle backdrops, GLTF showcases, or quick prototypes—whenever prompts mention 'three.js/threejs scene', '3D web background', 'orbit controls', or 'WebGL demo'.
Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including scripts and reference files (for example `references/advanced-topics.md`, `references/game-patterns.md` and `references/gltf-loading-guide.md`).
It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js. The repository describes itself as: Free Vibe Jam starter pack — battle-tested ThreeJS and Phaser agent skills, starter projects, and prompts.
When your agent uses it
- Tasks that involve 3D graphics and WebGL
Example prompts
- “three.js/threejs scene”
- “3D web background”
- “orbit controls”
- “/threejs-builder”
Requirements
- Python 3
- Node.js
Workflow steps
5 steps, taken from the step headings in SKILL.md.
- Frame the Experience
- Establish Runtime Foundations
- Compose the Scene
- Animate & Interact
- Polish & Performance
What it can do on your machine
Read from SKILL.md and the folder at commit 6793771. 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
Ships 3 files in scripts/ (JavaScript and Python), which the agent can run.
Shell commands in SKILL.md call:
python3
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
unpkg.com
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 Builder loads about 3.3k tokens when it runs, and up to ~17k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 1,350 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 1,350 words (~3,319 tokens).
“A Codex-ready framework for shipping elegant, performant Three.js web experiences with modern ES modules.”
