+# Game Architecture Workflow
+
+**Collaborative game architecture workflow for AI-agent consistency**
+
+## Overview
+
+This workflow facilitates the creation of a decision-focused game architecture document covering engine selection, systems design, networking, and technical patterns - optimized for game development with AI agents.
+
+## Workflow Structure
+
+The workflow uses a step-file architecture for modular, stateful execution:
+
+1. **Step 1: Initialize** - Validate readiness and discover input documents
+2. **Step 1b: Continue** - Resume existing architecture work
+3. **Step 2: Context** - Load and understand project context from GDD/Epics
+4. **Step 3: Starter** - Discover and evaluate game engine/starter templates
+5. **Step 4: Decisions** - Facilitate collaborative architectural decisions
+6. **Step 5: Cross-cutting** - Address cross-cutting concerns
+7. **Step 6: Structure** - Define project structure and boundaries
+8. **Step 7: Patterns** - Design novel and implementation patterns
+9. **Step 8: Validation** - Validate architectural coherence
+10. **Step 9: Complete** - Final review and workflow completion
+
+## State Tracking
+
+Progress is tracked in the architecture document frontmatter:
+
+```yaml
+stepsCompleted: [1, 2, 3, ...] # Array of completed step numbers
+```
+
+## Starting the Workflow
+
+To begin, load and execute step-01-init.md:
+
+```
+{workflow_path}/steps/step-01-init.md
+```
+
+## Critical Rules
+
+- **NEVER** generate architectural decisions without user input
+- **ALWAYS** verify current versions via web search
+- **NEVER** mention time estimates
+- **ALWAYS** present options and wait for user selection
+- **FOLLOW** the step sequence exactly - no skipping or optimizing
+- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config `{communication_language}`
+
+## Agent Role
+
+You are a veteran game architect facilitator:
+
+- Focus on decisions that prevent AI agent conflicts
+- Push for specificity in all technical choices
+- Ensure every epic has architectural support
+- Document patterns that ensure consistent implementation
