world-of-claudecraft: Skill for Codex

.agents/skills/woc-image-to-glb/SKILL.md

woc-image-to-glb is a skill for Codex from levy-street/world-of-claudecraft. It costs 83 tokens per session (415 once invoked), scanned A, original, MIT.

A guide for turning a reference image into a GLB, a 3D model file used in World of ClaudeCraft. It covers the project's required steps for creating, optimizing, checking, and registering an in-game asset.

In plain words
What is it for?
Create or replace 3D props, furniture, buildings, landmarks, stalls, and service objects; export them into the game; update their manifest entries; and run the required checks.
Why use it?
It provides a repeatable path from an image to a tested game asset, including source tracking and size limits. This reduces the risk of an asset working visually but failing the project's build or test checks.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: reads .claude/ paths; mentions CLAUDE.md; installed under .agents/ (shared by several agents).

This is levy-street/world-of-claudecraft's own configuration. It tells Codex how to work on world-of-claudecraft 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 world-of-claudecraft configures →

About the project

World of ClaudeCraft is a browser-based classic-style multiplayer online game with a persistent shared world that can also run locally or be controlled through a Python reinforcement-learning interface. Players can quest and raid in the online world, while developers can host it themselves and train AI agents to play. The catalogue skills, agents, instructions, hooks, and setting support workflows for interacting with and developing the game.

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

woc-image-to-glb 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 13d 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.

What it actually says

World of ClaudeCraft image-to-GLB

This is the Codex-side pointer for the shared asset pipeline. The canonical operating procedure is the Claude skill at .claude/skills/image-to-glb/SKILL.md; the deep runbook is docs/image-to-glb-asset-workflow.md. Follow those two documents exactly; do not improvise an alternative pipeline.

Quick orientation:

  1. Read scripts/assets/CLAUDE.md, then .claude/skills/image-to-glb/SKILL.md in full.
  2. The img2threejs skill (installed at ~/.codex/skills/img2threejs) drives reference admission, detail inventory, sculpt specs, and staged visual review. It is an authoring aid, never a build dependency.
  3. The committed chain is: reference (with provenance and a CREDITS.md row) -> budgets -> sculpt spec -> purpose-built factory (scripts/assets/<asset>/model.js, vertex colors, material buckets, sockets) -> deterministic exporter -> build_assets.mjs optimizer -> public/models/props/ -> media manifest -> parsed-GLB contract test -> render adapter module -> matched desktop/mobile in-game evidence -> npm run gate.
  4. Respect the source-fingerprint contract: any change to a fingerprinted input (including package-lock.json) means re-exporting the affected asset families and re-pinning the sha256 and fingerprint literals in tests, docs, and capture evidence JSONs.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
