Claude Code Game Studios is a setup that organizes Claude Code into a coordinated game-development team of specialized AI agents. It supports game projects across design, programming, art, audio, narrative, quality assurance, and production, with skills and workflows for coordinating that work.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 1 finding, up to medium
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 →
- medium Excessive Agency · line 7 Skill selects an external model or provider that may use a different account or billing plan than the operator expects. Undisclosed model switches can cause unexpected cost or quota consumption.Fix: Remove the model/provider override or disclose it prominently and require explicit operator approval before invoking an external coding CLI or billed model.
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 | $0.00042 | $0.03559 |
| Opus 5.5 | $0.00017 | $0.01424 |
| Sonnet 5.5 | $0.00008 | $0.00712 |
| Haiku 4.5 | $0.00004 | $0.00356 |
Grade A, and why
ux-review 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 4d 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.

UX Review
Overview
Validates UX design documents before they enter the implementation pipeline.
Acts as the quality gate between UX Design and Visual Design/Implementation in
the /team-ui pipeline.
Run this skill:
- After completing a UX spec with
/ux-design - Before handing off to
ui-programmerorart-director - Before the Pre-Production to Production gate check (which requires key screens to have reviewed UX specs)
- After major revisions to a UX spec
Verdict levels:
- APPROVED — spec is complete, consistent, and implementation-ready
- NOT ASSESSED — one or more review dimensions had no criterion to check against, or the spec could not be read; name which
- NEEDS REVISION — specific gaps found; fix before handoff but not a full redesign
- MAJOR REVISION NEEDED — fundamental issues with scope, player need, or completeness; needs significant rework
NOT ASSESSED ranks above APPROVED and below the two revision verdicts. A
review that could not evaluate a dimension has not shown the spec is
implementation-ready; but a gap somebody found is more actionable than one nobody
could look for, so it must not displace them. Emit it when the spec file cannot
be read, when a checklist dimension has no source of truth to compare against, or
when the accessibility tier is uncommitted (below).
Phase 1: Parse Arguments
- Specific file path (e.g.,
/ux-review design/ux/inventory.md): validate that one document all: find all files indesign/ux/and validate eachhud: validatedesign/ux/hud.mdspecificallypatterns: validatedesign/ux/interaction-patterns.mdspecifically- No argument: ask the user which spec to validate
For all, output a summary table first (file | verdict | primary issue) then
full detail for each.
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.

ux-review is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (27,298 stars, last pushed 5d ago), licensed MIT. It adds 42 tokens to every session and 3,559 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 2026-09-03.
