Turn a single Claude Code session into a full game development studio.
49 agents. 74 skills. One coordinated AI team.

Building a game solo with AI is powerful — but a single chat session has no structure. No one stops you from hardcoding magic numbers, skipping design docs, or writing spaghetti code. There's no QA pass, no design review, no one asking "does this actually fit the game's vision?"

Claude Code Game Studios solves this by giving your AI session the structure of a real studio. Instead of one general-purpose assistant, you get 49 specialized agents organized into a studio hierarchy — directors who guard the vision, department leads who own their domains, and specialists who do the hands-on work. Each agent has defined responsibilities, escalation paths, and quality gates.

The result: you still make every decision, but now you have a team that asks the right questions, catches mistakes early, and keeps your project organized from first brainstorm to launch.

Agents are organized into three tiers, matching how real studios operate:

Tier 1 — Directors
  creative-director    technical-director    producer

Tier 2 — Department Leads
  game-designer        lead-programmer       art-director
  audio-director       narrative-director    qa-lead
  release-manager      localization-lead

Tier 3 — Specialists
  gameplay-programmer  engine-programmer     ai-programmer
  network-programmer   tools-programmer      ui-programmer
  systems-designer     level-designer        economy-designer
  technical-artist     sound-designer        writer
  world-builder        ux-designer           prototyper
  performance-analyst  devops-engineer       analytics-engineer
  security-engineer    qa-tester             accessibility-specialist
  live-ops-designer    community-manager

Each agent declares a model in its frontmatter: the three directors ask for Opus, lead-programmer and fifteen specialists name Sonnet, and the remaining thirty inherit your session's model. Treat the tiers as seniority of role, not as a billing plan — most of the studio runs on whatever model you are already using.

The template includes agent sets for all three major engines. Use the set that matches your project:

A fair question, and the answer is a measurement rather than a sample project. Four games were built from one brief at different modes.rigor levels and the documents each wrote before its first line of game code were counted:

All of them produced a running, tested game. Two blind reviewers and a human playtest then ranked the standard build last — the extra 29 documents bought traceability, not a better game.

The measurement above is about cost. The other half is whether the thing works, and for a game that means someone has to look at it — a passing test says nothing about a menu drawn off-screen. So a story that changes anything the player sees is not closed until the game has been launched, observed, and a screenshot retained in production/qa/evidence/. A parse check is not a run. This holds at every rigor level, including minimal, where automated tests are waived but the look is not.

The games themselves are deliberately not shipped here: this is a template you clone to start your own project, and somebody else's game in your repo is clutter, not evidence.

• Git
• Claude Code — the native installer is recommended (npm install -g @anthropic-ai/claude-code also works, on Node.js 22+)
• Python 3 — reads project.yaml for every skill and hook; without it every setting silently falls back to its default
• Bash — runs every hook; built into macOS and Linux, and on Windows it comes with Git for Windows
• Recommended: jq (for hook validation)

Hooks fail gracefully if optional tools are missing — you just lose validation — with one deliberate exception: a commit that stages data JSON is blocked when there is no Python to validate it.

1. Clone or use as template:

   git clone https://github.com/Donchitos/Claude-Code-Game-Studios.git my-game
   cd my-game

2. Open Claude Code and start a session:

   claude

3. Run /start — the system asks where you are (no idea, vague concept, clear design, existing work) and guides you to the right workflow. No assumptions.

   Or jump directly to a specific skill if you already know what you need:

   • /brainstorm — explore game ideas from scratch
   • /setup-engine godot 4.6 — configure your engine if you already know
   • /project-stage-detect — analyze an existing project

project.yaml at the repo root is the single source of truth for how the studio behaves on your project — engine, naming conventions, and a modes block that controls how much process every skill enforces. /start writes it for you; you rarely need to hand-edit it.

The one question that matters most is modes.rigor — minimal, standard, or full. It's a single front door over six separate knobs (workflow — which GDD sections are required, docs.density, qa.level, story_granularity, review_mode — how many director agents review your work, and team.size), so /start asks it once instead of six times:

• minimal (default) — jam-game speed. No GDDs required, terse docs, minimal QA evidence, solo review. /start → /setup-engine → /brainstorm (a one-page brief) → /create-stories → /dev-story ↔ /story-done.
• standard — 5 required GDD sections, balanced doc depth, standard QA evidence, lean review.
• full — all 8 GDD sections, thorough docs, full QA evidence on every story type, full director review.

minimal is the default because it was measured against the alternatives: the heavier tier cost several times more to reach working code, was ranked last on play quality, and returned nothing measurable when a fresh developer inherited the project. Raise it in one /settings call when your project grows — /help and /gate-check will suggest it when they see the signs.

Two escape hatches keep one setting from being a blunt instrument. system_overrides holds a single system to a higher standard than the rest of the project — your combat system gets the full treatment while everything else stays light. testing.strict sets, per test type (logic, integration, visual, UI, config), whether missing evidence blocks a story or merely warns.

Any of the six underlying knobs can still be set individually if you want a mix (e.g. workflow: full with docs.density: terse — comprehensive but compact). Two of them — review_mode (full / lean / solo) and team.size — are also personal: rigor sets the team-wide default, but you can override them per-developer in a gitignored project.local.yaml without touching the shared config. modes.automation (how often the AI pauses to ask before it acts) sits outside rigor and is likewise personally overridable.

View or change any setting with the /settings skill:

/settings                              # view effective config
/settings modes.review_mode            # view one setting
/settings modes.rigor=full             # write to project.yaml (team-wide)
/settings --local modes.review_mode=solo   # write to project.local.yaml (just you)

Full schema and per-setting behavior: .claude/docs/effects-map.md.

CCGS is a template you are meant to edit. CCGS Skill Testing Framework/ is how you check that an edited or newly written skill still holds up — a catalog of all 74 skills and 49 agents, per-category quality rubrics, behavioral specs, and templates for writing specs of your own.

/skill-test static [name]     # structural linter — 7 compliance checks
/skill-test category [name]   # category-specific quality rubric
/skill-test spec [name]       # behavioral spec assertions
/skill-test audit             # coverage report across skills and agents
/skill-improve [name]         # test-fix-retest loop; keeps or reverts on score change

It tests the framework, never your game — game tests live in tests/.

Agents follow a structured delegation model:

1. Vertical delegation — directors delegate to leads, leads delegate to specialists
2. Horizontal consultation — same-tier agents can consult each other but can't make binding cross-domain decisions
3. Conflict resolution — disagreements escalate up to the shared parent (creative-director for design, technical-director for technical)
4. Change propagation — cross-department changes are coordinated by producer
5. Domain boundaries — agents don't modify files outside their domain without explicit delegation

This is not an auto-pilot system. Every agent follows a strict collaboration protocol:

1. Ask — agents ask questions before proposing solutions
2. Present options — agents show 2-4 options with pros/cons
3. You decide — the user always makes the call
4. Draft — agents show work before finalizing
5. Approve — nothing gets written without your sign-off

You stay in control. The agents provide structure and expertise, not autonomy.

Hooks run automatically on every session:

Note: validate-commit.sh, validate-assets.sh, and validate-skill-change.sh fire on every Bash, PowerShell or Write tool call and exit immediately (exit 0) when the command or file path is not relevant. This is normal hook behavior — not a performance concern.

Permission rules in settings.json auto-allow safe operations (git status, test runs) and block dangerous ones (force push, rm -rf, reading .env files) in both the Bash and PowerShell tools. The git rules match anywhere after git, so a git command whose text only mentions push followed later by + or -f, clean followed by -f, or reset followed by --hard — a commit message such as git commit -m "push + pull" included — is denied too: reword the message.

Coding standards are automatically enforced based on file location. The paths below are Godot's. Each rule also matches the Unity and Unreal layouts: the code rules match C# under Assets/**/Gameplay/ and C++ under Source/**/Gameplay/ (and Core, AI, Networking, UI), data matches JSON under Assets/**/Data/ and Content/**/Data/, shaders match by file type, and tests match C# under Assets/Tests/ and C++ under Source/**/Tests/.

This template is grounded in professional game development practices:

• MDA Framework — Mechanics, Dynamics, Aesthetics analysis for game design
• Self-Determination Theory — Autonomy, Competence, Relatedness for player motivation
• Flow State Design — Challenge-skill balance for player engagement
• Bartle Player Types — Audience targeting and validation
• Verification-Driven Development — Tests first, then implementation

This is a template, not a locked framework. Everything is meant to be customized:

• Add/remove agents — delete agent files you don't need, add new ones for your domains
• Edit agent prompts — tune agent behavior, add project-specific knowledge
• Modify skills — adjust workflows to match your team's process
• Add rules — create new path-scoped rules for your project's directory structure
• Tune hooks — adjust validation strictness, add new checks
• Pick your engine — use the Godot, Unity, or Unreal agent set (or none)
• Tune process weight — modes.rigor and its underlying knobs in project.yaml (see Configuration). Override per-run with --review solo on any skill.

Primary development on Windows 10 with Git Bash. The hooks and scripts are also tested on macOS — its stock bash 3.2 and BSD tools, with and without jq — and on Linux. All hooks use POSIX-compatible patterns (grep -E, not grep -P) and include fallbacks for missing tools. The notify.sh hook uses PowerShell for Windows toast notifications and is a no-op elsewhere — desktop notifications on macOS/Linux are not yet wired. Please file issues for any platform-specific breakage.
