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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00058 | $0.00470 |
| Opus 5 | $0.00029 | $0.00235 |
| Sonnet 5 | $0.00012 | $0.00094 |
| Haiku 4.5 | $0.00006 | $0.00047 |
Grade A, and why
woc-release-malware-audit 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
Release Malware Audit
Determine whether the release tree contains deliberate malicious behavior or unresolved indicators that make release unsafe. This is read-only: do not modify files, dependencies, Git history, or remote state.
Establish scope
- Read the root
CLAUDE.mdand instructions for relevant release, script, server, deployment, and security paths. - Run
git status --short. - Record the exact commit, branch, tag, or working tree.
- Audit the whole release tree, not only the latest diff.
Do not expose secrets or inspect unrelated private data.
Scan once
The coordinating agent runs:
node scripts/malware_scan.mjs --json --quiet
Exit 0 means no findings, 1 means findings need triage, and 2 means the scan failed.
Capture structured output under a temporary path only when needed and preserve evidence.
Triage
Group findings by category and file. Dispatch independent read-only triage in parallel when useful. Specialists inspect files and shared output without rerunning the scanner.
Review credential or wallet theft, exfiltration, covert telemetry, backdoors, auth bypasses, command execution, obfuscated or fetched payloads, dependency and lifecycle abuse, cryptomining, resource hijacking, and instruction injection. Include sensitive behavior hidden in tests, fixtures, generated assets, documentation, and release tools.
For each flag, inspect context, reachability, intent, data flow, and whether it ships or executes. Accidental defects belong in a normal security review, but unresolved ambiguity in executable or release-critical content still blocks release.
Return PASS only when every finding and manual concern has a supported benign
explanation. Return BLOCK for malicious, reachable suspicious, or unresolved behavior.
Report the revision, tree state, scanner count, confirmed and unresolved indicators,
dismissed flags with evidence, manual coverage, limitations, and verdict.
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.
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.

woc-release-malware-audit is a skill published in the GitHub repository levy-street/world-of-claudecraft (2,251 stars, last pushed yesterday), licensed MIT. It adds 58 tokens to every session and 470 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
