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 9 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 | $0.00045 | $0.02036 |
| Opus 5 | $0.00023 | $0.01018 |
| Sonnet 5 | $0.00009 | $0.00407 |
| Haiku 4.5 | $0.00005 | $0.00204 |
Grade A, and why
help 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 7d 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 — 229 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Studio Help — What Do I Do Next?
This skill is read-only — it reports findings but writes no files.
This skill figures out exactly where you are in the game development pipeline and
tells you what comes next. It is lightweight — not a full audit. For a full
gap analysis, use /project-stage-detect.
Step 1: Read the Catalog
Read .claude/docs/workflow-catalog.yaml. This is the authoritative list of all
phases, their steps (in order), whether each step is required or optional, and
the artifact globs that indicate completion.
Step 1b: Find Skills Not in the Catalog
After reading the catalog, Glob .claude/skills/*/SKILL.md to get the full list
of installed skills. For each file, extract the name: field from its frontmatter.
Compare against the command: values in the catalog. Any skill whose name does
not appear as a catalog command is an uncataloged skill — still usable but not
part of the phase-gated workflow.
Collect these for the output in Step 7 — show them as a footer block:
### Also installed (not in workflow)
- `/skill-name` — [description from SKILL.md frontmatter]
- `/skill-name` — [description]
Only show this block if at least one uncataloged skill exists. Limit to the 10 most relevant based on the user's current phase (QA skills in production, team skills in production/polish, etc.).
Step 2: Determine Current Phase
Check in this order:
-
Read
production/stage.txt— if it exists and has content, this is the authoritative phase name. Map it to a catalog phase key:- "Concept" →
concept - "Systems Design" →
systems-design - "Technical Setup" →
technical-setup - "Pre-Production" →
pre-production - "Production" →
production - "Polish" →
polish - "Release" →
release
- "Concept" →
-
If stage.txt is missing, infer phase from artifacts (most-advanced match wins):
src/has 10+ source files →productionproduction/stories/*.mdexists →pre-productiondocs/architecture/adr-*.mdexists →technical-setupdesign/gdd/systems-index.mdexists →systems-designdesign/gdd/game-concept.mdexists →concept- Nothing →

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.

help is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (24,949 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 2,036 once invoked, about $0.0002 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 2026-09-03.
