Skill for Claude Code

Written for Claude Code: when-to-use in frontmatter. Also seen: installed under .agents/ (shared by several agents).

This is nirholas/three.ws's own configuration. It tells Claude Code how to work on three.ws itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything three.ws configures →

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

embed-three-ws-avatar 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 14d 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.

How it starts

The opening of the file, as written. The whole thing — 159 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Embed a three.ws avatar on any site

The <agent-3d> web component renders a rigged, animated 3D avatar (GLB) with zero framework dependencies. It works in plain HTML, React, Vue, Svelte, Angular, WordPress, Webflow, Shopify, Framer, and Notion embeds. The bundle is served from the three.ws CDN with access-control-allow-origin: *, so it loads from any origin.

Quick start

<script
  type="module"
  src="https://three.ws/agent-3d/1.5.2/agent-3d.js"
  integrity="sha384-KdAiFRsdcCbQMu4O5rkoL8hOEYLkmrdpf9ELd7jro+9NTNipWis3oqqFLll7v20Q"
  crossorigin="anonymous"
></script>

<agent-3d
  body="https://three.ws/avatars/default.glb"
  mode="section"
  kiosk
  poster="/images/avatar-poster.webp"
  style="width:100%;height:420px;display:block"
></agent-3d>

A UMD build exists at the same path as agent-3d.umd.cjs if ES modules are not an option.

Pick the right CDN channel (do not ship latest)

Path Cache Use when
/agent-3d/<MAJOR>.<MINOR>.<PATCH>/agent-3d.js immutable, 1 year production. Pin exact bytes, always combine with SRI
/agent-3d/<MAJOR>.<MINOR>/agent-3d.js 5 min follow patch releases automatically
/agent-3d/<MAJOR>/agent-3d.js 5 min follow minor + patch releases
/agent-3d/latest/agent-3d.js 5 min demos and prototypes only

latest can ship breaking changes with no action on your side. For production, pin an exact version with an integrity attribute. Machine-readable release data:

  • https://three.ws/agent-3d/versions.json: current version, channels, publish time.
  • https://three.ws/agent-3d/<version>/integrity.json: sha384 SRI hashes for that exact version.

Getting a GLB for body

Any humanoid GLB URL works. Models generated on three.ws come back on persistent https://three.ws/cdn/forge/... URLs you can use directly in body with no re-hosting (self-hosting also works if you want control):

  • Generate from text or a reference image: the create-3d-avatar skill (rigged, animation-ready) or generate-3d-model (static prop). Both return a glbUrl.
  • Rig an existing GLB: the rig-a-model skill.
  • Let end users design one interactively: the Avatar Studio iframe flow below.

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.
