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 | $0.00061 | $0.02303 |
| Opus 5 | $0.00030 | $0.01151 |
| Sonnet 5 | $0.00012 | $0.00461 |
| Haiku 4.5 | $0.00006 | $0.00230 |
Grade A, and why
create-epics 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 — 246 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Create Epics
An epic is a named, bounded body of work that maps to one architectural module. It defines what needs to be built and who owns it architecturally. It does not prescribe implementation steps — that is the job of stories.
Run this skill once per layer as you approach that layer in development. Do not create Feature layer epics until Core is nearly complete — the design will have changed.
Output: production/epics/[epic-slug]/EPIC.md + production/epics/index.md
Next step after each epic: /create-stories [epic-slug]
When to run: After /create-control-manifest and /architecture-review pass.
1. Parse Arguments
Resolve the review mode (once, store for all gate spawns this run):
- If
--review [full|lean|solo]was passed → use that - Else read
production/review-mode.txt→ use that value - Else → default to
lean
See .claude/docs/director-gates.md for the full check pattern.
Modes:
/create-epics all— process all systems in layer order/create-epics layer: foundation— Foundation layer only/create-epics layer: core— Core layer only/create-epics layer: feature— Feature layer only/create-epics layer: presentation— Presentation layer only/create-epics [system-name]— one specific system- No argument — ask: "Which layer or system would you like to create epics for?"
2. Load Inputs
Step 2a — Summary scan (fast)
Grep all GDDs for their ## Summary sections before reading anything fully:
Grep pattern="## Summary" glob="design/gdd/*.md" output_mode="content" -A 5
For layer: or [system-name] modes: filter to only in-scope GDDs based on
the Summary quick-reference. Skip full-reading anything out of scope.
Step 2b — Full document load (in-scope systems only)
Using the Step 2a grep results, identify which systems are in scope. Read full documents only for in-scope systems — do not read GDDs or ADRs for out-of-scope systems or layers.
Read for in-scope systems:
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.

create-epics is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (24,822 stars, last pushed 3mo ago), licensed MIT. It adds 61 tokens to every session and 2,303 once invoked, about $0.0003 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.
