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 | $0.00021 | $0.04875 |
| Opus 5.5 | $0.00008 | $0.01950 |
| Sonnet 5.5 | $0.00004 | $0.00975 |
| Haiku 4.5 | $0.00002 | $0.00487 |
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 yesterday.
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
3 near-identical copies found in the catalogue:
- sprint-plan — 97% identical, 214 lines differ
- sprint-plan — 86% identical, 238 lines differ

How it starts
The opening of the file, as written. The whole thing — 405 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 review_mode,automation,story_granularity,workflow
Resolved above — use as-is; --review overrides review_mode. No block →
defaults in .claude/docs/config-resolution.md.
Sprint Plan
Existing Sprints
!ls production/sprints/ 2>/dev/null || echo "(no production/sprints/ directory yet)"
Resolved before this skill runs — use it to identify the previous sprint in Phase 1 rather than re-globbing.
Phase 0: Parse Arguments
Extract the mode argument (new, update, or status).
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).
story_granularity — it sets how
many stories to allocate per sprint, scaled by velocity: 2–4 at coarse (the default, via rigor: minimal),
6–10 at balanced (rigor: standard), 15–25 at fine. A Ready backlog
smaller than the range is planned whole — never padded with invented stories.
Review mode check (before gates run):
- Use the review mode from the resolved block above (
--reviewoverrides it for this run) — do not re-resolve it, and do not ask for it. With nothing configured it followsmodes.rigor:soloatminimal,leanatstandard. - Never write a review mode — not to
project.yaml, not toproduction/review-mode.txt.modes.review_modeis one of the knobsmodes.rigorfronts: pinning it inproject.yamlshadows the rigor expansion, and the legacy file sits above that expansion, so either write would freeze director-review depth for good.--reviewcovers a one-off. If the user wants a different depth to persist, point them to changingmodes.rigor(/settings modes.rigor=<minimal|standard|full>), or to pinning it on purpose with/settings --local modes.review_mode=<full|lean|solo>(a personal override inproject.local.yaml).
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 (26,985 stars, last pushed 2d ago), licensed MIT. It adds 21 tokens to every session and 4,875 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.
Other skills, from other repositories
work-log-claude
A work-log generator that reads Claude Code's local session records and produces an evidence-based Markdown report. It can organise work by project and time period while excluding unrelated session data.
dare-refine
Analisa complexidade de uma task DARE e, quando alta, quebra em sub-tasks menores. Use após gerar o DAG (para tasks HIGH/CRITICAL), quando o dev pedir refinamento manual, ou quando o escopo mudou e uma task ficou grande. Combina heurística determinística (CLI) com decisão semântica do agente.
dare-dag
Mostra o DAG estático de tasks (DARE/dare-dag.yaml): ranks, dependências e caminho crítico. Use dare dag viz para exportar o diagrama. Mapeia o CLI dare dag.
dare-graph
Consulta e visualiza o grafo de conhecimento do projeto (tasks, arquivos, schemas, endpoints, componentes, entidades e suas relações). Mapeia o CLI dare graph.
project-diagnosis
Structured gap analysis that identifies what a project is missing — not what's done poorly (that's /audit), but what's absent entirely. Checks for tests, CI, security basics, linting, type safety, deployment readiness, and dependency health. Each finding has a severity and a concrete fix action.
tech-debt-tracking
Track shortcuts with justifications, prevent debt accumulation, and surface outstanding debt at session start.
