What it does
Threejs Builder is an agent skill from chongdashu/cc-skills-nanobananapro. Creates simple Three.js web apps with scene setup, lighting, geometries, materials, animations, and responsive rendering. Use for: "Create a threejs scene/app/showcase" or when user wants 3D web content. Supports ES modules, modern Three.js r150+ APIs.
Its SKILL.md is about 3.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/advanced-topics.md`).
It sits in Game Development, covering 3D graphics and WebGL. It works with Three.js.
When your agent uses it
- : Create a threejs scene/app/showcase
- User wants 3D web content
Example prompts
- “Create a threejs scene/app/showcase”
- “Use the threejs-builder skill to create simple Three.js web apps with scene setup, lighting, geometries, materials, animations, and responsive…”
- “/threejs-builder”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Scene Graph First: Everything added to scene renders. Use Group for hierarchical transforms.
- Primitives as Building Blocks: Built-in geometries (Box, Sphere, Torus) cover 80% of simple use cases.
- Animation as Transformation: Change position/rotation/scale over time using requestAnimationFrame or renderer.setAnimationLoop.
- Performance Through Simplicity: Fewer objects, fewer draw calls, reusable geometries/materials.
What it can do on your machine
Read from SKILL.md and the folder at commit 6e8a27f. 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 (its code samples are javascript and html).
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 3.1k tokens when it runs, and up to ~5.9k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 770 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 770 words (~3,089 tokens).
“A focused skill for creating simple, performant Three.js web applications using modern ES module patterns.”
