Game Studio Agent Architecture — complete setup (Phases 1-7)

48 coordinated Claude Code subagents for indie game development:
- 3 leadership agents (creative-director, technical-director, producer)
- 10 department leads (game-designer, lead-programmer, art-director, etc.)
- 23 specialist agents (gameplay, engine, AI, networking, UI, tools, etc.)
- 12 engine-specific agents (Godot, Unity, Unreal with sub-specialists)

Infrastructure:
- 34 skills (slash commands) for workflows, reviews, and team orchestration
- 8 hooks for commit validation, asset checks, session management
- 11 path-scoped rules enforcing domain-specific standards
- 28 templates for design docs, reports, and collaborative protocols

Key features:
- User-driven collaboration protocol (Question → Options → Decision → Draft → Approval)
- Engine version awareness with knowledge-gap detection (Godot 4.6 pinned)
- Phase gate system for development milestone validation
- CLAUDE.md kept under 80 lines with extracted doc imports

+# Unreal Engine — Version Reference
+
+| Field | Value |
+|-------|-------|
+| **Engine Version** | Unreal Engine 5.7 |
+| **Release Date** | November 2025 |
+| **Project Pinned** | 2026-02-13 |
+| **Last Docs Verified** | 2026-02-13 |
+| **LLM Knowledge Cutoff** | May 2025 |
+
+## Knowledge Gap Warning
+
+The LLM's training data likely covers Unreal Engine up to ~5.3. Versions 5.4, 5.5,
+5.6, and 5.7 introduced significant changes that the model does NOT know about.
+Always cross-reference this directory before suggesting Unreal API calls.
+
+## Post-Cutoff Version Timeline
+
+| Version | Release | Risk Level | Key Theme |
+|---------|---------|------------|-----------|
+| 5.4 | ~Mid 2025 | HIGH | Motion Design tools, animation improvements, PCG enhancements |
+| 5.5 | ~Sep 2025 | HIGH | Megalights (millions of lights), animation authoring, MegaCity demo |
+| 5.6 | ~Oct 2025 | MEDIUM | Performance optimizations, bug fixes |
+| 5.7 | Nov 2025 | HIGH | PCG production-ready, Substrate production-ready, AI assistant |
+
+## Major Changes from UE 5.3 to UE 5.7
+
+### Breaking Changes
+- **Substrate Material System**: New material framework (replaces legacy materials)
+- **PCG (Procedural Content Generation)**: Production-ready, major API changes
+- **Megalights**: New lighting system (millions of dynamic lights)
