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 | $0.00030 | $0.01169 |
| Opus 5.5 | $0.00012 | $0.00468 |
| Sonnet 5.5 | $0.00006 | $0.00234 |
| Haiku 4.5 | $0.00003 | $0.00117 |
Grade A, and why
adopt scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 95 lines — stays where its author put it; the contents beside it link to each section on GitHub.
!bash "${CLAUDE_SKILL_DIR}/../../hooks/yaml-helper.sh" resolve_config --keys review_mode,automation,automation_always_ask,workflow
Resolved above — use as-is. /adopt also inspects project.yaml and the legacy
config files directly when reporting and writing migration state; that raw
inspection is deliberate and separate from the resolved values above.
Adopt — Brownfield Template Adoption
This skill audits an existing project's artifacts for format compliance with the template's skill pipeline, then produces a prioritised migration plan.
This is not /project-stage-detect.
/project-stage-detect answers: what exists?
/adopt answers: will what exists actually work with the template's skills?
A project can have GDDs, ADRs, and stories — and every format-sensitive skill will still fail silently or produce wrong results if those artifacts are in the wrong internal format.
Output: docs/adoption-plan-[date].md — a persistent, checkable migration plan.
Argument modes:
Audit mode: $ARGUMENTS (blank = full)
- No argument /
full: Complete audit — all artifact types gdds: GDD format compliance onlyadrs: ADR format compliance onlystories: Story format compliance onlyinfra: Infrastructure artifact gaps only (registry, manifest, sprint-status, stage.txt)
Automation mode: Resolve modes.automation (project.local.yaml →
project.yaml → default collaborative). 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).
workflow (per .claude/docs/workflow-modes.md). It scopes the Phase 2 audit and
Phase 3 severity: full audits all doc types at full structure; standard audits
only the required docs/sections (optional sections are informational, not gaps);
minimal is a design/game-brief.md format check — GDDs/ADRs/UX are not expected. See Phase 2.
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

adopt is a skill published in the GitHub repository Donchitos/Claude-Code-Game-Studios (26,726 stars, last pushed 8d ago), licensed MIT. It adds 30 tokens to every session and 1,169 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 2026-08-30.

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-graph
Consulta e visualiza o grafo de conhecimento do projeto (tasks, arquivos, schemas, endpoints, componentes, entidades e suas relações). Mapeia o CLI dare graph.
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.
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.
