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 | $0.00024 | $0.05330 |
| Opus 5.5 | $0.00010 | $0.02132 |
| Sonnet 5.5 | $0.00005 | $0.01066 |
| Haiku 4.5 | $0.00002 | $0.00533 |
Grade A, and why
map-systems 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.
Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 456 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Map Systems
When this skill is invoked:
Parse Arguments
Two modes:
- No argument:
/map-systems— Run the full decomposition workflow (Phases 1-5) to create or update the systems index. next:/map-systems next— Pick the highest-priority undesigned system from the index and hand off to/design-system(Phase 6).
See .claude/docs/director-gates.md for the full check pattern. Individual gate definitions live in .claude/docs/director-gates/[gate-id].md — the spawned agent reads its own gate file; do not read it in the parent session.
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). In collaborative mode the
system list, dependency, priority and write approvals are separate questions:
each waits for its answer before the next step runs.
docs.density — it controls per-section depth, where workflow
controls which sections exist. modes.rigor sets both together; set
docs.density explicitly to vary depth alone: terse (the default, via rigor: minimal) = one-line system descriptions;
balanced = a brief paragraph per system + dependency notes (rigor: standard);
thorough = full system-by-system rationale + relationship analysis. Apply it to
every section you author.
Where the per-system prose goes.
templates/systems-index.md's Systems Enumeration is a fixed-column table with no description column, so atbalancedandthoroughthe prose belongs in## Overview— one short paragraph per system atbalanced, plus relationship analysis atthorough— and in the## Dependency Maplayer notes. Do not add a column to the enumeration table — it is a fixed contract in.claude/docs/templates/systems-index.md, and its consumers (/design-system§6 and §7,/create-epics) are written against the columns it defines. Widening it is a schema change, not a formatting choice.How the consumers actually read it. Nothing parses this table positionally. The two scripts that mention
systems-index.md(gdd-structure-check.sh:51,review-scope.sh:40) match it by filename in acasestatement and parse no columns at all; the two skills key on theCategorycolumn by name (design-system:229,:780). SoCategoryis the column that must never be renamed or dropped, and the table stays a fixed contract because every consumer is written against the set of columns the template defines. Atterse, the table plus a one-paragraph## Overviewis the whole output.
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.

map-systems is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (26,893 stars, last pushed yesterday), licensed MIT. It adds 24 tokens to every session and 5,330 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.
