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.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00127 | $0.01868 |
| Opus 5 | $0.00063 | $0.00934 |
| Sonnet 5 | $0.00025 | $0.00374 |
| Haiku 4.5 | $0.00013 | $0.00187 |
Grade A, and why
i18n-locale-fill 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 2d 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 — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.
i18n locale fill (release time)
Contributors add ENGLISH only; the maintainer fills every locale at release. This skill is
that fill workflow. The release-tier gate (I18N_RELEASE_TIER=1, automatic on release/**
branches) hard-fails on any pending registry row, so a release is not shippable until the
fill lands.
1. Generate the worklist
npm run i18n:gen # refresh the registry first
npm run i18n:worklist # writes one batch per language under docs/i18n-scaling/worklist/ (gitignored)
scripts/i18n_fill_worklist.mjs is data-only (no translation): each batch entry carries
{ scope, key, english, placeholders, siblings }.
main-scope keys are filled in the matchingsrc/ui/i18n.locales/<lang>.tsoverlay.sim/server/adminscope keys are filled in their matcher DICTs (the worklist header inscripts/i18n_fill_worklist.mjsnames the exact files).- Sim-scope keys DO reach the worklist (since Masterwrought Phase 19F, ruling
qr-19-sim-scope-pending-is-unreachable): the registry reads each locale's OWN source
blocks through
simDictProvidedKeysinsrc/ui/sim_i18n.ts, never the assembledDICT(which is dense by construction,baseEnTablespread under every locale), so a sim row with no fill in a locale's block ispendingand lands in that locale's batch. Fill a sim key in the locale'sBASE_DICTblock ofsrc/ui/sim_i18n.ts(the eight newest locales keep theirs inBASE_NEWofsrc/ui/sim_i18n.newlocales.ts, a hand-maintained file despite its old banner; each of those locales' own block insim_i18n.tsspreadsBASE_NEWin the MIDDLE of its literal rows, so a key spelled in both is read from whichever spelling comes last in the block, and the registry's row-count anchor intests/i18n_status_registry.test.tsreds on the duplicate either way), and NEVER paste the English into a locale block: a copied row readstranslatedand ships English (the sim scope has no copied-English guard; onlytests/localization_fixes.test.ts's release-tiers3_localizedarm sees it late). Runnpm run i18n:genbefore the suites: the registry pin compares the artifact against the live source and reds on a stale one. The five per-locale*_EXTRAtables the RULES matchers read (arena, battleground, quest, item, raid) are tsc-forced dense and stay outside the registry; check them by eye at release. humanRequiredentries are blocked by default (quest narratives, names, lore, SEO copy): never machine-fill them; onlyautoFillableentries are fair game for a model pass.
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.

i18n-locale-fill is a skill published in the GitHub repository levy-street/world-of-claudecraft (2,251 stars, last pushed yesterday), licensed MIT. It adds 127 tokens to every session and 1,868 once invoked, about $0.0006 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.
