Game Studio Agent Architecture -- Quick Start Guide
What Is This?
This is a complete Claude Code agent architecture for game development. It organizes 49 specialized AI agents into a studio hierarchy that mirrors real game development teams, with defined responsibilities, delegation rules, and coordination protocols. It includes engine-specialist agents for Godot, Unity, and Unreal — each with dedicated sub-specialists for major engine subsystems. All design agents and templates are grounded in established game design theory (MDA Framework, Self-Determination Theory, Flow State, Bartle Player Types). Use whichever engine set matches your project.
How to Use
1. Understand the Hierarchy
There are three tiers of agents:
-
Tier 1 (Opus): Directors who make high-level decisions
creative-director-- vision and creative conflict resolutiontechnical-director-- architecture and technology decisionsproducer-- scheduling, coordination, and risk management
-
Tier 2 (Sonnet): Department leads who own their domain
game-designer,lead-programmer,art-director,audio-director,narrative-director,qa-lead,release-manager,localization-lead
-
Tier 3 (Sonnet/Haiku): Specialists who execute within their domain
- Designers, programmers, artists, writers, testers, engineers
2. Pick the Right Agent for the Job
Ask yourself: "What department would handle this in a real studio?"

4. Use Templates for New Documents
Templates are in .claude/docs/templates/:
game-design-document.md-- for new mechanics and systemsarchitecture-decision-record.md-- for technical decisionsarchitecture-traceability.md-- maps GDD requirements to ADRs to story IDsrisk-register-entry.md-- for new risksnarrative-character-sheet.md-- for new characterstest-plan.md-- for feature test planssprint-plan.md-- for sprint planningmilestone-definition.md-- for new milestoneslevel-design-document.md-- for new levelsgame-pillars.md-- for core design pillarsart-bible.md-- for visual style referencetechnical-design-document.md-- for per-system technical designspost-mortem.md-- for project/milestone retrospectivessound-bible.md-- for audio style referencerelease-checklist-template.md-- for platform release checklistschangelog-template.md-- for player-facing patch notesrelease-notes.md-- for player-facing release notesincident-response.md-- for live incident response playbooksgame-concept.md-- for initial game concepts (MDA, SDT, Flow, Bartle)pitch-document.md-- for pitching the game to stakeholderseconomy-model.md-- for virtual economy design (sink/faucet model)faction-design.md-- for faction identity, lore, and gameplay rolesystems-index.md-- for systems decomposition and dependency mappingproject-stage-report.md-- for project stage detection outputdesign-doc-from-implementation.md-- for reverse-documenting existing code into GDDsarchitecture-doc-from-code.md-- for reverse-documenting code into architecture docsconcept-doc-from-prototype.md-- for reverse-documenting prototypes into concept docsux-spec.md-- for per-screen UX specifications (layout zones, states, events)hud-design.md-- for whole-game HUD philosophy, zones, and element specsaccessibility-requirements.md-- for project-wide accessibility tier and feature matrixinteraction-pattern-library.md-- for standard UI controls and game-specific patternsplayer-journey.md-- for 6-phase emotional arc and retention hooks by time scaledifficulty-curve.md-- for difficulty axes, onboarding ramp, and cross-system interactionstest-evidence.md-- template for recording manual test evidence (screenshots, walkthrough notes)
Also in .claude/docs/templates/collaborative-protocols/ (used by agents, not typically edited directly):
design-agent-protocol.md-- question-options-draft-approval cycle for design agentsimplementation-agent-protocol.md-- story pickup through /story-done cycle for programming agentsleadership-agent-protocol.md-- cross-department delegation and escalation for director-tier agents
5. Follow the Coordination Rules
- Work flows down the hierarchy: Directors -> Leads -> Specialists
- Conflicts escalate up the hierarchy
- Cross-department work is coordinated by the
producer - Agents do not modify files outside their domain without delegation
- All decisions are documented
First Steps for a New Project
Don't know where to begin? Run /start. It asks where you are and routes
you to the right workflow. No assumptions about your game, engine, or experience level.
If you already know what you need, jump directly to the relevant path:
Path A: "I have no idea what to build"
- Run
/start(or/brainstorm open) — guided creative exploration: what excites you, what you've played, your constraints- Generates 3 concepts, helps you pick one, defines core loop and pillars
- Produces a game concept document and recommends an engine
- Set up the engine — Run
/setup-engine(uses the brainstorm recommendation)- Configures CLAUDE.md, detects knowledge gaps, populates reference docs
- Creates
.claude/docs/technical-preferences.mdwith naming conventions, performance budgets, and engine-specific defaults - If the engine version is newer than the LLM's training data, it fetches current docs from the web so agents suggest correct APIs
- Validate the concept — Run
/design-review design/gdd/game-concept.md - Decompose into systems — Run
/map-systemsto map all systems and dependencies - Design each system — Run
/design-system [system-name](or/map-systems next) to write GDDs in dependency order - Prototype the mechanic — Run
/prototype [core-mechanic](1–3 days — before writing GDDs) - Design each system — Run
/design-system [system-name]to write GDDs, informed by prototype findings - Plan the first sprint — After architecture and
/vertical-slice, run/sprint-plan new - Start building
Path B: "I know what I want to build"
If you already have a game concept and engine choice:
- Set up the engine — Run
/setup-engine [engine] [version](e.g.,/setup-engine godot 4.6) — also creates technical preferences - Write the Game Pillars — delegate to
creative-director - Decompose into systems — Run
/map-systemsto enumerate systems and dependencies - Design each system — Run
/design-system [system-name]for GDDs in dependency order - Create the initial ADR — Run
/architecture-decision - Create the first milestone in
production/milestones/ - Plan the first sprint — Run
/sprint-plan new - Start building
Path C: "I know the game but not the engine"
If you have a concept but don't know which engine fits:
- Run
/setup-enginewith no arguments — it will ask about your game's needs (2D/3D, platforms, team size, language preferences) and recommend an engine based on your answers - Follow Path B from step 2 onward
Path D: "I have an existing project"
If you have design docs, prototypes, or code already:
- Run
/start(or/project-stage-detect) — analyzes what exists, identifies gaps, and recommends next steps - Run
/adoptif you have existing GDDs, ADRs, or stories — audits internal format compliance and builds a numbered migration plan to fill gaps without overwriting your existing work - Configure engine if needed — Run
/setup-engineif not yet configured - Validate phase readiness — Run
/gate-checkto see where you stand - Plan the next sprint — Run
/sprint-plan new
