Turn a single Claude Code session into a full game development studio.
49 agents. 72 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.

| Category | Count | Description |
|---|---|---|
| Agents | 49 | Specialized subagents across design, programming, art, audio, narrative, QA, and production |
| Skills | 72 | Slash commands for every workflow phase (/start, /design-system, /create-epics, /create-stories, /dev-story, /story-done, etc.) |
| Hooks | 12 | Automated validation on commits, pushes, asset changes, session lifecycle, agent audit trail, and gap detection |
| Rules | 11 | Path-scoped coding standards enforced when editing gameplay, engine, AI, UI, network code, and more |

Agents are organized into three tiers, matching how real studios operate:
Tier 1 — Directors (Opus)
creative-director technical-director producer
Tier 2 — Department Leads (Sonnet)
game-designer lead-programmer art-director
audio-director narrative-director qa-lead
release-manager localization-lead
Tier 3 — Specialists (Sonnet/Haiku)
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
The template includes agent sets for all three major engines. Use the set that matches your project:
| Engine | Lead Agent | Sub-Specialists |
|---|---|---|
| Godot 4 | godot-specialist |
GDScript, Shaders, GDExtension |
| Unity | unity-specialist |
DOTS/ECS, Shaders/VFX, Addressables, UI Toolkit |

- Git
- Claude Code (
npm install -g @anthropic-ai/claude-code) - Recommended: jq (for hook validation) and Python 3 (for JSON validation)
All hooks fail gracefully if optional tools are missing — nothing breaks, you just lose validation.
-
Clone or use as template:
git clone https://github.com/Donchitos/Claude-Code-Game-Studios.git my-game cd my-game -
Open Claude Code and start a session:
claude
-
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

Agents follow a structured delegation model:
- Vertical delegation — directors delegate to leads, leads delegate to specialists
- Horizontal consultation — same-tier agents can consult each other but can't make binding cross-domain decisions
- Conflict resolution — disagreements escalate up to the shared parent (
creative-directorfor design,technical-directorfor technical) - Change propagation — cross-department changes are coordinated by
producer - 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:
- Ask — agents ask questions before proposing solutions
- Present options — agents show 2-4 options with pros/cons
- You decide — the user always makes the call
- Draft — agents show work before finalizing
- 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:
| Hook | Trigger | What It Does |
|---|---|---|
validate-commit.sh |
PreToolUse (Bash) | Checks for hardcoded values, TODO format, JSON validity, design doc sections — exits early if the command is not git commit |
validate-push.sh |
PreToolUse (Bash) | Warns on pushes to protected branches — exits early if the command is not git push |
validate-assets.sh |
PostToolUse (Write/Edit) | Validates naming conventions and JSON structure — exits early if the file is not in assets/ |
session-start.sh |
Session open | Shows current branch and recent commits for orientation |
detect-gaps.sh |
Session open | Detects fresh projects (suggests /start) and missing design docs when code or prototypes exist |
pre-compact.sh |
Before compaction | Preserves session progress notes |
post-compact.sh |
After compaction | Reminds Claude to restore session state from active.md |
notify.sh |
Notification event | Shows Windows toast notification via PowerShell |
session-stop.sh |
Session close | Archives active.md to session log and records git activity |
log-agent.sh |
Agent spawned | Audit trail start — logs subagent invocation |
log-agent-stop.sh |
Agent stops | Audit trail stop — completes subagent record |
validate-skill-change.sh |
PostToolUse (Write/Edit) | Advises running /skill-test after any .claude/skills/ change |
Note:
validate-commit.sh,validate-assets.sh, andvalidate-skill-change.shfire on every Bash/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).
Coding standards are automatically enforced based on file location:
| Path | Enforces |
|---|---|
src/gameplay/** |
Data-driven values, delta time usage, no UI references |
src/core/** |
Zero allocations in hot paths, thread safety, API stability |
src/ai/** |
Performance budgets, debuggability, data-driven parameters |
src/networking/** |
Server-authoritative, versioned messages, security |
src/ui/** |
No game state ownership, localization-ready, accessibility |
design/gdd/** |
Required 8 sections, formula format, edge cases |
tests/** |
Test naming, coverage requirements, fixture patterns |
prototypes/** |
Relaxed standards, README required, hypothesis documented |
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)
- Set review intensity —
full(all director gates),lean(phase gates only), orsolo(none). Set during/startor editproduction/review-mode.txt. Override per-run with--review soloon any skill.
Tested on Windows 10 with Git Bash. All hooks use POSIX-compatible patterns (grep -E, not grep -P) and include fallbacks for missing tools. Works on macOS and Linux without modification.
