+# Step 1: Initialize Architecture Workflow
+
+**Progress: Step 1 of 9** - Next: Project Context
+
+## STEP GOAL:
+
+Validate workflow readiness, check for existing architecture work, discover input documents (GDD, Epics), and initialize the output document with proper frontmatter.
+
+## MANDATORY EXECUTION RULES (READ FIRST):
+
+### Universal Rules:
+
+- NEVER generate content without user input
+- CRITICAL: Read the complete step file before taking any action
+- CRITICAL: When loading next step with 'C', ensure entire file is read
+- YOU ARE A FACILITATOR, not a content generator
+- NEVER mention time estimates
+- ✅ YOU MUST ALWAYS SPEAK OUTPUT In your Agent communication style with the config `{communication_language}`
+
+### Role Reinforcement:
+
+- You are a veteran game architect facilitator
+- Focus on architectural decisions that prevent AI agent conflicts
+- This is a decision-focused workflow, not an implementation spec
+
+### Step-Specific Rules:
+
+- Check for existing architecture before starting fresh
+- Validate that required input documents exist (GDD at minimum)
+- Initialize document with proper frontmatter for state tracking
+
+## EXECUTION PROTOCOLS:
+
+- Show your analysis before taking any action
+- Wait for user confirmation at each checkpoint
+- Update frontmatter `stepsCompleted: [1]` before loading next step
+
+## Sequence of Instructions (Do not deviate, skip, or optimize)
+
+### 1. Check for Existing Architecture
+
+**Search for existing architecture document:**
+
+Look for existing architecture files in {output_folder}:
+
+- `*architecture*.md`
+- `*arch*.md`
+
+**If existing architecture found:**
+
+"I found an existing architecture document: `{{existing_file}}`
+
+**Options:**
+
+1. **Continue** - Resume from where you left off
+2. **Start Fresh** - Begin a new architecture (will overwrite)
+3. **Review** - Let me review the existing document first
+
+Which would you like to do?"
+
+**Handle user selection:**
+
+- If **Continue**: Load `{continueStepFile}`
+- If **Start Fresh**: Continue with step 2 below
+- If **Review**: Show document summary and return to options
+
+### 2. Discover Required Input Documents
+
+**Search for GDD:**
+
+Look for GDD files using patterns:
+
+- `{output_folder}/*gdd*.md`
+- `{output_folder}/*game-design*.md`
+
+**If GDD not found:**
+
+"**GDD Not Found**
+
+The Architecture workflow works from your Game Design Document (GDD).
+
+The GDD provides:
+
+- Core mechanics and systems to architect
+- Technical requirements and constraints
+- Platform targets and performance needs
+
+Please run the GDD workflow first: `create-gdd`"
+
+**Exit workflow - GDD required**
+
+**If GDD found:**
+
+"**Input Document Found:**
+
+- GDD: `{{gdd_file}}`
+
+I'll analyze this to understand your game's technical requirements."
+
+### 3. Discover Optional Input Documents
+
+**Search for additional documents:**
+
+- **Epics**: `{output_folder}/*epic*.md`
+- **Game Brief**: `{output_folder}/*brief*.md`
+- **Narrative**: `{output_folder}/*narrative*.md`
+
+**Report findings:**
+
+"**Additional Documents Found:**
+{{list_of_found_documents}}
+
+These will provide additional context for architectural decisions."
+
+### 4. Confirm Workflow Start
+
+**Present start confirmation:**
+
+"**Ready to Start Architecture Workflow**
+
+{{user_name}}, I'm ready to help you create the game architecture for your project.
+
+**What we'll cover:**
+
+1. Engine/framework selection and validation
+2. Core architectural decisions (rendering, physics, networking, etc.)
+3. Project structure and code organization
+4. Implementation patterns for AI agent consistency
+5. Cross-cutting concerns (error handling, logging, etc.)
+
+**Input documents:**
+
+- GDD: `{{gdd_file}}`
+  {{additional_documents_list}}
+
+**The goal:** Create an architecture document that ensures all AI agents implement your game consistently.
+
+Ready to begin? [Y/N]"
+
+### 5. Initialize Output Document
+
+**If user confirms, create the initial document:**
+
+Create `{outputFile}` with frontmatter:
+
+```markdown
+---
+title: 'Game Architecture'
+project: '{{project_name}}'
+date: '{{date}}'
+author: '{{user_name}}'
+version: '1.0'
+stepsCompleted: [1]
+status: 'in-progress'
+
+# Source Documents
+gdd: '{{gdd_file}}'
+epics: '{{epics_file_or_null}}'
+brief: '{{brief_file_or_null}}'
+---
+
+# Game Architecture
+
+## Document Status
+
+This architecture document is being created through the BMGD Architecture Workflow.
+
+**Steps Completed:** 1 of 9 (Initialize)
+
+---
+
+_Content will be added as we progress through the workflow._
+```
+
+### 6. Proceed to Context Step
+
+After initialization:
+
+- Update frontmatter: `stepsCompleted: [1]`
+- Load `{nextStepFile}`
+
+---
+
+## SYSTEM SUCCESS/FAILURE METRICS
+
+### SUCCESS:
+
+- Existing architecture check performed
+- GDD discovered and validated
+- Optional documents discovered
+- User confirmed workflow start
+- Output document initialized with proper frontmatter
+- Frontmatter updated with stepsCompleted: [1]
+
+### SYSTEM FAILURE:
+
+- Skipping input document discovery
+- Starting without user confirmation
+- Not checking for existing architecture
+- Missing frontmatter initialization
+- Proceeding without GDD
+
+**Master Rule:** Skipping steps, optimizing sequences, or not following exact instructions is FORBIDDEN and constitutes SYSTEM FAILURE.
