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 | $0.00024 | $0.02484 |
| Opus 5.5 | $0.00010 | $0.00994 |
| Sonnet 5.5 | $0.00005 | $0.00497 |
| Haiku 4.5 | $0.00002 | $0.00248 |
Grade A, and why
write-changelog scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 264 lines — stays where its author put it; the contents beside it link to each section on GitHub.
!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys automation
Automation mode: Resolve modes.automation (project.local.yaml →
project.yaml → default collaborative). Every question and
every file write follows .claude/docs/automation-modes.md
(collaborative asks always · guided major-only · autonomous logs and proceeds;
automation_always_ask categories always prompt).
Changelog
Recent History
Recent commits:
!git log --oneline -30 2>/dev/null || true
Recent tags (newest first):
!git tag --list --sort=-v:refname 2>/dev/null | head -5
Provenance check — before trusting the history above
The commits above may not belong to this game. This skill's history blocks are auto-resolved before the body runs, so the read has already happened — what this check governs is whether that output is usable, not whether it is fetched.
- Read the injected commit subjects above. If there are none — the log is empty or git is unavailable — skip this check: there is nothing to classify, and Phase 1's no-history branch is the right stop.
- Classify each one as Game (mechanics, content, balance, art, audio, UI, or a bug in those), Framework / maintenance (subjects naming skills, hooks, agents, the test plan, CI, or the framework's own docs), or Unclear — and treat Unclear as Framework.
- Decide from the counts:
- At least one Game commit → proceed using only those, and state how many of how many you used.
- Zero Game commits → stop, using the message below.
Filter per commit; a repo containing maintenance work is not a wrong repo. Every project on this framework accumulates commits touching hooks, CI and skills — the game repo is the framework repo, so stopping on them would fire on virtually every real project. The harm is those commits becoming release copy, and excluding them prevents that precisely.
This rule is kept identical to
/patch-notes' on purpose — the two read the same history for different audiences, and they must not disagree about whose history it is. Change both together.
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.

write-changelog is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (38,742 stars, last pushed 3d ago), licensed MIT. It adds 24 tokens to every session and 2,484 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 2026-11-09.
