What it does

Cobejs is an agent skill from nirholas/three.ws. Use when adding a lightweight interactive globe with cobe (canvas setup, markers, interaction, performance, integration with React/Next.js).

Its SKILL.md is about 570 tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files (for example `REFERENCES.md` and `demo/PROMPT.md`).

It sits in Game Development. It works with Next.js and React. The repository describes itself as: Open-source platform for 3D AI agents. Turn text or a photo into a rigged, animated GLB avatar, give it an LLM brain, memory and a wallet, and embed it anywhere with one web… The licence is Apache-2.0.

Example prompts

What it can do on your machine

Read from SKILL.md and the folder at commit 238ef60. 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).
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

Cobejs loads about 567 tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 141 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~37
When it runs · the whole SKILL.md, loaded when a task matches: ~567

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.

cobe.js — Lightweight WebGL Globe Skill

When to use

A “spinning globe” / location markers in hero or about pages
You want a small, focused globe lib (not full three.js)
Decorative + interactive (markers, rotation) with minimal setup

Key APIs/patterns

Core:
- import createGlobe from "cobe"
- const globe = createGlobe(canvas, { ...options, onRender(state) { ... } })
Important options (common):
- devicePixelRatio, width, height
- phi, theta (rotation angles)
- scale, dark, diffuse
- baseColor, markerColor, glowColor
- markers: [{ location: [lat, lon], size, color? }]
Lifecycle:
- globe.toggle() pauses RAF
- globe.destroy() removes instance

Common pitfalls

Canvas sizing mismatch
- Set CSS size AND set canvas width/height scaled for DPR.
Not updating on resize
- Recompute width/height and recreate or update params.
Too high DPR on mobile
- Clamp DPR to 1–2.

Quick recipe: responsive globe with markers

import createGlobe from "cobe";

const canvas = document.getElementById("cobe");
let phi = 0;

function setup() {
  const rect = canvas.getBoundingClientRect();
  const dpr = Math.min(window.devicePixelRatio, 2);
  canvas.width = Math.round(rect.width * dpr);
  canvas.height = Math.round(rect.height * dpr);

  const globe = createGlobe(canvas, {
    devicePixelRatio: dpr,
    width: canvas.width,
    height: canvas.height,
    phi: 0,
    theta: 0.2,
    dark: 0,
    diffuse: 1.2,
    scale: 1,
    mapSamples: 16000,
    mapBrightness: 6,
    baseColor: [0.2, 0.2, 0.25],
    glowColor: [1, 1, 1],
    markerColor: [0.8, 0.5, 1],
    markers: [{ location: [1.3521, 103.8198], size: 0.08 }],
    onRender: (state) => {
      state.phi = phi;
      phi += 0.01;
    },
  });

  return globe;
}

let globe = setup();
window.addEventListener("resize", () => {
  globe.destroy();
  globe = setup();
});

What to ask the user

Globe size and placement (hero, section, card)?
Marker locations + colors (brand-aligned)?
Interaction needs (drag to rotate vs. ambient spin)?
