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 | $0.00062 | $0.00649 |
| Opus 5.5 | $0.00025 | $0.00260 |
| Sonnet 5.5 | $0.00012 | $0.00130 |
| Haiku 4.5 | $0.00006 | $0.00065 |
Grade A, and why
woc-review-pr 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 1mo 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 — 63 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Review Pull Request
Perform a read-only, evidence-backed review of the requested pull request.
Hold the authorization boundary
A request to review, inspect, check, or assess authorizes reading and drafting only. Do
not run gh pr review, post a comment, approve, request changes, push, edit the branch,
or otherwise write to GitHub unless the user explicitly asks to submit the review.
Establish scope
- Read the root
CLAUDE.mdin full. - Identify the pull request, repository, head, base, and merge base.
- Read local
CLAUDE.mdfiles for touched directories. - Inspect the actual diff, surrounding production code, and linked acceptance criteria.
- Run
git status --shortand avoid disturbing unrelated work.
Use read-only Git and GitHub inspection as needed. Do not rely on the PR description.
Review and verify
Check correctness, edge cases, canonical architecture, determinism, parity, persistence, security, authorization, localization, generated artifacts, decisive tests, and updated operator documentation wherever those domains apply.
The coordinating agent runs targeted commands once. Specialist reviewers inspect the diff and shared results without duplicating the full test or build run.
Invoke woc_database_performance when the diff changes SQL, a database call site,
schema or indexes, query frequency/cardinality, pool or lock behavior, timeout policy,
background database work, database driver/dependency versions, PostgreSQL
engine/resource/configuration/topology, or stored-data growth. Pair it with persistence or security
review when those concerns also apply.
Invoke woc_server_hot_path when the diff adds or changes server work that runs per tick,
per request, per broadcast, per session, or on a recurring main-thread job: a shared read or
cache, a growing table or in-memory collection, a snapshot or event payload, a selfWireJson
key or the src/sim/ read it calls, an autosave, sweep, or self-clocked job, or a
world_state blob write. It owns the non-SQL server budget; pair it with
woc_database_performance when SQL cost is also in play.
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-review-pr is a skill published in the GitHub repository levy-street/world-of-claudecraft (2,323 stars, last pushed today), licensed MIT. It adds 62 tokens to every session and 649 once invoked, about $0.0002 per session on Opus 5.5. 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.

autoreview
Structured code review through the shared OpenClaw agent-skills installation.
omh-code-review
This is an OMH code-review workflow skill, projected for Agent Skills hosts (Claude Code, Codex, Cursor, opencode, OpenClaw, pi).
revdiff-plan
Review the last Codex assistant message (plan, analysis, or proposal) with inline annotations in a TUI overlay. Extracts the most recent response from Codex rollout files and opens it in revdiff for review and annotation. Activates on "revdiff-plan", "review plan with revdiff", "annotate plan", "review last response"…
explore-unknowns
Guide the user through a quadrant walk that maps the unknowns of a task — open by listing the known knowns, then work through known unknowns, unknown knowns, and unknown unknowns one stage at a time, ending with a complete four-quadrant map in the user's hands. Use when a request is ambiguous or underspecified, the…
re0-merge
Review and land an external contribution the way this suite does: gate it against the thesis, land it with the author's credit intact, complete a new skill rather than merging it raw, then approve, credit, and explain before closing. Use when reviewing a pull request, as any collaborator or maintainer, not only the…
