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 | $0.00039 | $0.02812 |
| Opus 5 | $0.00019 | $0.01406 |
| Sonnet 5 | $0.00008 | $0.00562 |
| Haiku 4.5 | $0.00004 | $0.00281 |
Grade A, and why
sprint-plan 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 — 282 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Phase 0: Parse Arguments
Extract the mode argument (new, update, or status) and 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.
Review mode check (before gates run):
- Read
production/review-mode.txtif it exists. Use that mode. - If the file doesn't exist and this is a
newsprint: useAskUserQuestion:- Prompt: "No review mode is set. Which review depth would you like for this sprint?"
- Options:
[A] full — spawn all director and lead gates[B] lean — skip non-phase-gate director reviews (recommended for most sprints)[C] solo — skip all gate spawning
- After selection: write
production/review-mode.txtwith the chosen mode. Say: "Review mode set to [mode] and saved to production/review-mode.txt."
- If the file doesn't exist and this is NOT a
newsprint (e.g., updating an existing sprint): default toleansilently.
Phase 1: Gather Context
-
Read the current milestone from
production/milestones/. -
Read the previous sprint (if any) from
production/sprints/to understand velocity and carryover. -
Scan design documents in
design/gdd/for features tagged as ready for implementation. -
Check the risk register at
production/risk-register/.
Phase 2: Generate Output
For new:
Generate a sprint plan following this format and present it to the user. Do NOT ask to write yet — the producer feasibility gate (Phase 4) runs first and may require revisions before the file is written.

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.

sprint-plan is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (24,834 stars, last pushed 3mo ago), licensed MIT. It adds 39 tokens to every session and 2,812 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.
