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: 3 findings, 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.
- medium Excessive Agency · line 913 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.

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 | $0.00031 | $0.02252 |
| Opus 5.5 | $0.00012 | $0.00901 |
| Sonnet 5.5 | $0.00006 | $0.00450 |
| Haiku 4.5 | $0.00003 | $0.00225 |
Grade A, and why
ux-design 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 today.
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 — 193 lines — stays where its author put it; the contents beside it link to each section on GitHub.
!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys automation,workflow,docs.density
Resolved above — use as-is. No block → defaults in
.claude/docs/config-resolution.md.
UX Design
When this skill is invoked:
Every AskUserQuestion call follows .claude/docs/automation-modes.md
(collaborative asks always · guided major-only · autonomous logs and proceeds;
automation_always_ask categories always prompt).
Authoring guidance: the skeletons below are self-contained — author from them directly. When a section needs depth (worked examples, pattern catalogs, accessibility criteria), the matching guide has it:
| Producing | Guide |
|---|---|
| UX spec | .claude/docs/templates/guidance/ux-spec-guide.md |
| HUD design | .claude/docs/templates/guidance/hud-design-guide.md |
| Interaction patterns | .claude/docs/templates/guidance/interaction-pattern-library-guide.md (routes to three topic files) |
| Accessibility requirements | .claude/docs/templates/guidance/accessibility-requirements-guide.md |
Load a guide per-section, never whole — each is organised by section and the pointers in the templates name the exact section to read.
workflow (see .claude/docs/workflow-modes.md):
full— a UX spec is required per screen.standard— core screens only (main menu, HUD, primary game loop).minimal— not required. Can still be run voluntarily.
docs.density — it controls per-section depth, where workflow
controls which screens are specced. modes.rigor sets both together; set
docs.density explicitly to vary depth alone: terse (the default, via rigor: minimal) = wireframe descriptions +
interaction bullets; balanced = wireframes + paragraph descriptions of flows
(rigor: standard); thorough = full prose including user-research summaries and
alternative flow considerations. Apply it to every section you author.
1. Parse Arguments & Determine Mode
Four authoring modes exist based on the argument:
What ships with it
7 files 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.

ux-design is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (26,893 stars, last pushed yesterday), licensed MIT. It adds 31 tokens to every session and 2,252 once invoked, about $0.0001 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.
