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.

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 | $0.00049 | $0.02980 |
| Opus 5 | $0.00024 | $0.01490 |
| Sonnet 5 | $0.00010 | $0.00596 |
| Haiku 4.5 | $0.00005 | $0.00298 |
Grade A, and why
test-setup 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 — 427 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Test Setup
This skill scaffolds the automated testing infrastructure for the project. It detects the configured engine, generates the appropriate test runner configuration, creates the standard directory layout, and wires up CI/CD so tests run on every push.
Run this once during the Technical Setup phase, before any implementation begins. A test framework installed at sprint start costs 30 minutes. A test framework installed at sprint four costs 3 sprints.
Output: tests/ directory structure + .github/workflows/tests.yml
Phase 1: Detect Engine and Existing State
-
Read engine config:
- Read
.claude/docs/technical-preferences.mdand extract theEngine:value. - If engine is not configured (
[TO BE CONFIGURED]), stop: "Engine not configured. Run/setup-enginefirst, then re-run/test-setup."
- Read
-
Check for existing test infrastructure:
- Glob
tests/— does the directory exist? - Glob
tests/unit/andtests/integration/— do subdirectories exist? - Glob
.github/workflows/— does a CI workflow file exist? - Glob
tests/gdunit4_runner.gd(Godot) ortests/EditMode/(Unity) orSource/Tests/(Unreal) for engine-specific artifacts.
- Glob
-
Report findings:
- "Engine: [engine]. Test directory: [found / not found]. CI workflow: [found / not found]."
- If everything already exists AND
forceargument was not passed: "Test infrastructure appears to be in place. Re-run with/test-setup forceto regenerate. Proceeding will not overwrite existing test files."
If the force argument is passed, skip the "already exists" early-exit and
proceed — but still do not overwrite files that already exist at a given path.
Only create files that are missing.
Phase 2: Present Plan
Based on the engine detected and the existing state, present a plan:
## Test Setup Plan — [Engine]
I will create the following (skipping any that already exist):
tests/
unit/ — Isolated unit tests for formulas, state, and logic
integration/ — Cross-system tests and save/load round-trips
smoke/ — Critical path test list (15-minute manual gate)
evidence/ — Screenshot and manual test sign-off records
README.md — Test framework documentation
[Engine-specific files — see per-engine details below]
.github/workflows/tests.yml — CI: run tests on every push to main
Estimated time: ~5 minutes to create all files.
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.

test-setup is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (24,822 stars, last pushed 3mo ago), licensed MIT. It adds 49 tokens to every session and 2,980 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.
