+# Random Mesh Generator Test Addon - Installation & Testing Guide
+
+This guide walks you through properly installing and testing the Random Mesh Generator addon to validate the complete Blender AI Router pipeline.
+
+## Installation Steps
+
+### 1. Locate Your Blender Addons Directory
+
+Find your Blender addons directory based on your operating system:
+
+**Linux:**
+
+```bash
+~/.config/blender/[version]/scripts/addons/
+# Example: ~/.config/blender/4.2/scripts/addons/
+```
+
+**Windows:**
+
+```
+%APPDATA%\Blender Foundation\Blender\[version]\scripts\addons\
+# Example: C:\Users\YourName\AppData\Roaming\Blender Foundation\Blender\4.2\scripts\addons\
+```
+
+**macOS:**
+
+```bash
+~/Library/Application Support/Blender/[version]/scripts/addons/
+# Example: ~/Library/Application Support/Blender/4.2/scripts/addons/
+```
+
+### 2. Install the Test Addon
+
+Copy the entire `random_mesh_generator` folder to your Blender addons directory:
+
+```bash
+# Example for Linux
+cp -r backend/test_addons/random_mesh_generator/ ~/.config/blender/4.2/scripts/addons/
+```
+
+### 3. Enable the Addon in Blender
+
+1. Open Blender
+2. Go to **Edit > Preferences > Add-ons**
+3. Search for "Random Mesh Generator"
+4. Enable the checkbox next to "Testing: Random Mesh Generator"
+5. The addon should now appear in Blender's Add menu
+
+### 4. Verify Blender Integration
+
+Test the addon directly in Blender first:
+
+1. Go to **Add > Mesh > Random Mesh Generator**
+2. Try each option:
+   - Random Cube
+   - Random Sphere
+   - Random Cylinder
+   - Surprise Me!
+3. You should see random meshes being created in the scene
+
+## Testing AI Router Discovery
+
+### 1. Install and Enable the AI Router
+
+The AI Router addon (`backend/blender_cr8tive_engine/`) must also be installed:
+
+```bash
+# Copy the AI Router to Blender addons
+cp -r backend/blender_cr8tive_engine/ ~/.config/blender/4.2/scripts/addons/blender_ai_router
+```
+
+Enable it in Blender preferences:
+
+- Search for "Blender AI Router"
+- Enable the addon
+
+### 2. Test Registry Discovery
+
+Create a simple test script in Blender's Text Editor:
+
+```python
+import sys
+from pathlib import Path
+
+# Access the AI Router registry
+import blender_ai_router.registry.addon_registry as registry_module
+
+# Initialize registry
+registry = registry_module.AIAddonRegistry()
+
+# Check discovered addons
+registered_addons = registry.get_registered_addons()
+print(f"Found {len(registered_addons)} AI-capable addons:")
+
+for addon_id, manifest in registered_addons.items():
+    addon_info = manifest.addon_info
+    tools = manifest.get_tools()
+    print(f"- {addon_info.get('name')} (ID: {addon_id})")
+    print(f"  Tools: {[tool['name'] for tool in tools]}")
+
+# Test command routing
+if 'random_mesh_generator' in registered_addons:
+    router = registry_module.AICommandRouter(registry)
+
+    # Test a command
+    result = router.route_command(
+        command='add_random_cube',
+        params={'size': 2.0, 'location': [0, 0, 0]},
+        addon_id='random_mesh_generator'
+    )
+    print(f"Command result: {result}")
+else:
+    print("Random Mesh Generator not found!")
+```
+
+### 3. Expected Results
+
+If everything is working correctly, you should see:
+
+```
+Found 1 AI-capable addons:
+- Random Mesh Generator (ID: random_mesh_generator)
+  Tools: ['add_random_cube', 'add_random_sphere', 'add_random_cylinder', 'add_surprise_mesh']
+
+Command result: {'status': 'success', 'message': 'Added random cube "Cube.001" to scene', 'data': {...}}
+```
+
+## Testing Full Pipeline Integration
+
+### 1. Start the Cr8 System
+
+With both addons installed and enabled in Blender:
+
+```bash
+# Start the FastAPI server (cr8_engine)
+cd backend/cr8_engine
+python main.py
+
+# Start Blender with the AI Router addon enabled
+# The router will connect to the FastAPI WebSocket
+```
+
+### 2. Verify B.L.A.Z.E Capabilities
+
+Check that B.L.A.Z.E now has the new mesh generation tools:
+
+- The DynamicMCPServer should detect the new addon
+- B.L.A.Z.E's system prompt should include Random Mesh Generator capabilities
+- Users should be able to request mesh creation through the chat interface
+
+### 3. Test Commands Through B.L.A.Z.E
+
+Try asking B.L.A.Z.E:
+
+- "Add a random cube to the scene"
+- "Create a sphere with some randomness"
+- "Surprise me with a random mesh"
+
+## Marketplace Validation
+
+This test validates the complete marketplace workflow:
+
+1. **✅ Addon Installation**: User copies addon to Blender directory
+2. **✅ Blender Registration**: User enables addon in preferences
+3. **✅ AI Router Discovery**: Router scans and finds addon manifest
+4. **✅ Dynamic Registration**: Router registers addon tools
+5. **✅ MCP Integration**: FastAPI receives new capabilities
+6. **✅ B.L.A.Z.E Enhancement**: AI agent gains new powers instantly
+7. **✅ Command Execution**: Users can use new capabilities immediately
+
+## Troubleshooting
+
+### Addon Not Found
+
+- Verify the addon is copied to the correct directory
+- Ensure the addon is enabled in Blender preferences
+- Check Blender's console for any import errors
+
+### Registry Issues
+
+- Make sure the AI Router addon is installed and enabled
+- Check that both `addon_ai.json` files are valid JSON
+- Look for error messages in Blender's console
+
+### Command Failures
+
+- Verify the addon's Python functions work directly in Blender
+- Check parameter types and validation
+- Ensure Blender has an active scene and proper context
+
+## Next Steps
+
+After successful testing:
+
+1. Create additional test addons for different categories
+2. Test with multiple addons installed simultaneously
+3. Validate the complete user experience from addon installation to AI interaction
+4. Document the addon development process for marketplace creators
+
+This testing validates that the architecture is ready for a real addon marketplace where users can install new capabilities and immediately see them available in B.L.A.Z.E.

 You are B.L.A.Z.E (Blender's Artistic Zen Engineer), an intelligent assistant that helps users control 3D scenes in Blender through natural language.
 
-Your primary role is to:
-1. Understand user requests for scene manipulation
-2. Use available MCP tools to execute changes
-3. Provide clear feedback about what was accomplished
+Your capabilities are dynamically determined by the AI-capable addons currently installed in Blender. 
 
-AVAILABLE TOOLS:
-Scene Control Tools:
-- switch_camera(camera_name): Switch to a specific camera
-- update_light_color(light_name, color): Change light color (use hex like #FF0000)
-- update_light_strength(light_name, strength): Adjust light intensity (0-1000)
-- update_light_properties(light_name, color, strength): Update both at once
-- update_material_color(material_name, color): Change material color
-- move_object(object_name, x, y, z): Move object to coordinates
-- rotate_object(object_name, x, y, z): Rotate object by degrees
-- scale_object(object_name, x, y, z): Scale object by factors
-
-Asset Control Tools:
-- add_asset(empty_name, filepath, asset_name): Add asset to position
-- remove_assets(empty_name): Remove assets from position
-- swap_assets(empty1_name, empty2_name): Swap assets between positions
-- rotate_assets(empty_name, degrees): Rotate assets
-- scale_assets(empty_name, scale_percent): Scale assets (100 = normal)
-- reset_asset_rotation(empty_name): Reset asset rotation
-- reset_asset_scale(empty_name): Reset asset scale
-- get_asset_info(empty_name): Get asset information
-
-GUIDELINES:
-- Be conversational and helpful
-- Always use the exact names provided in scene context
-- For colors, use hex format (#FF0000 for red, #00FF00 for green, etc.)
-- For light strength, use values between 100-1000 for typical lighting
-- Confirm what you've done after executing commands
-- If a request is unclear, ask for clarification
-- If scene elements aren't available, explain what's currently in the scene
-
-Remember: You have access to the current scene context, so you know what cameras, lights, materials, and objects are available.
+Currently no addons are available. Please ensure Blender is connected and AI-capable addons are installed.

+# Blender Multi Addon Architecture Implementation
+
+## Overview
+
+This document describes the implementation of the Blender Multi Addon Architecture Specification v0.1, which transforms the Cr8-xyz system from a monolithic Blender addon to a marketplace-ready router architecture. This enables dynamic capability discovery where users can install AI-capable addons that immediately extend B.L.A.Z.E (the AI agent) capabilities.
+
+## Architecture Transformation
+
+### Before: Monolithic System
+
+```
+Frontend ↔ FastAPI (cr8_engine) ↔ WebSocket ↔ blender_cr8tive_engine (Monolithic Addon)
+```
+
+### After: Router-Based System
+
+```
+Frontend ↔ FastAPI (cr8_engine) ↔ WebSocket ↔ AI Router Addon ↔ Capability Addons
+                ↓
+            B.L.A.Z.E Agent (Dynamic Capabilities)
+```
+
+## Key Components Implemented
+
+### 1. AI Router Addon (`backend/blender_cr8tive_engine/`)
+
+The main addon was transformed from a monolithic system to a pure router that:
+
+- Discovers AI-capable addons through manifest scanning
+- Routes commands to appropriate capability addons
+- Handles WebSocket communication with the FastAPI backend
+- Manages dynamic capability registration
+
+**Key Files:**
+
+- `__init__.py` - Router addon entry point with command handlers
+- `addon_ai.json` - Router's own AI capability manifest
+- `registry/addon_registry.py` - Core registry for addon discovery and validation
+- `registry/command_router.py` - Command routing and parameter validation
+- `ws/websocket_handler.py` - Updated WebSocket handler for registry events
+
+### 2. Addon Manifest Standard
+
+**Format: `addon_ai.json`**
+
+```json
+{
+  "addon_info": {
+    "id": "addon_identifier",
+    "name": "Human Readable Name",
+    "version": "0.1.0",
+    "author": "Developer Name",
+    "category": "modeling|animation|rendering|simulation|io|utility|procedural|texturing|sculpting",
+    "description": "Brief description"
+  },
+  "ai_integration": {
+    "agent_description": "Natural language description for AI agent",
+    "tools": [
+      {
+        "name": "tool_name",
+        "description": "What this tool does",
+        "usage": "When/why to use this tool",
+        "parameters": [
+          {
+            "name": "param_name",
+            "type": "string|integer|float|boolean|object_name|material_name|collection_name|enum|vector3|color|file_path",
+            "description": "Parameter description",
+            "required": true|false,
+            "default": "default_value",
+            "min": 0,
+            "max": 100,
+            "options": ["option1", "option2"]
+          }
+        ],
+        "examples": ["Natural language usage examples"]
+      }
+    ],
+    "context_hints": ["Guidelines for AI usage"],
+    "requirements": {
+      "blender_version_min": "4.0",
+      "depends_on": ["required_addon_ids"],
+      "conflicts_with": ["conflicting_addon_ids"]
+    }
+  }
+}
+```
+
+### 3. Command Handler Standard
+
+Each AI-capable addon MUST export command handlers:
+
+```python
+# In addon's __init__.py
+def example_tool_handler(**kwargs) -> dict:
+    """Standard handler function signature"""
+    try:
+        # Implementation here
+        return {
+            "status": "success",
+            "message": "Operation completed successfully",
+            "data": {}  # Optional additional data
+        }
+    except Exception as e:
+        return {
+            "status": "error",
+            "message": str(e),
+            "error_code": "OPERATION_FAILED"
+        }
+
+AI_COMMAND_HANDLERS = {
+    "example_tool": example_tool_handler,
+    # ... more handlers
+}
+```
+
+### 4. Registry System (`backend/blender_cr8tive_engine/registry/`)
+
+#### AIAddonRegistry (`addon_registry.py`)
+
+- **Purpose**: Discovers and validates AI-capable addons
+- **Key Methods**:
+  - `scan_addons()` - Scans Blender addon directories for `addon_ai.json` files
+  - `validate_manifest()` - Validates manifest format and requirements
+  - `register_addon()` - Registers addon in the system
+  - `get_available_tools()` - Returns all available tools for agent context
+
+#### AICommandRouter (`command_router.py`)
+
+- **Purpose**: Routes commands to appropriate addons with parameter validation
+- **Key Methods**:
+  - `route_command()` - Routes command to appropriate addon handler
+  - `execute_command()` - Executes command on specific addon
+- **Features**:
+  - Comprehensive parameter validation
+  - Type checking (string, integer, float, boolean, vector3, color, enum, etc.)
+  - Standardized error handling
+
+### 5. Dynamic MCP Server (`backend/cr8_engine/app/blaze/mcp_server.py`)
+
+Replaced static `BlazeServer` with `DynamicMCPServer`:
+
+```python
+class DynamicMCPServer:
+    def refresh_capabilities(self, addon_manifests: List[dict]):
+        """Update available tools based on addon manifests"""
+
+    def register_addon_tools(self, manifest: dict):
+        """Register tools from a single addon manifest"""
+
+    def build_agent_context(self, manifests: List[dict]) -> str:
+        """Generate dynamic system prompt from manifests"""
+```
+
+**Key Features:**
+
+- **Dynamic Tool Registration**: Auto-generates MCP tools from addon manifests
+- **Runtime Capability Discovery**: Updates available tools when addons are installed/removed
+- **Dynamic System Prompts**: AI agent context updates automatically with new capabilities
+
+### 6. Updated B.L.A.Z.E Agent (`backend/cr8_engine/app/blaze/agent.py`)
+
+Enhanced to handle dynamic capabilities:
+
+- **Registry Update Handling**: Processes addon registry changes
+- **Dynamic Capability Integration**: Automatically gains new abilities when addons are installed
+- **Graceful Degradation**: Handles scenarios when no addons are available
+
+## WebSocket Communication Protocol
+
+### Command Format (FastAPI → Blender)
+
+```json
+{

+
+## Implementation Timeline
+
+### Phase 1: Core Infrastructure ✅
+
+- [x] Main AI addon registry and router
+- [x] Manifest loading and validation
+- [x] Basic command routing
+- [x] WebSocket protocol implementation
+
+### Phase 2: Dynamic Integration ✅
+
+- [x] FastAPI dynamic tool registration
+- [x] Agent context generation
+- [x] B.L.A.Z.E agent dynamic capabilities
+- [x] Registry event system
+
+### Phase 3: Dependency Issue Resolution ✅
+
+- [x] **Problem**: "no module named yaml" error when installing in Blender
+- [x] **Root Cause**: PyYAML not included in Blender's Python environment
+- [x] **Solution**: Converted entire system from YAML to JSON format
+- [x] **Changes Made**:
+  - Converted `addon_ai.yaml` to `addon_ai.json` format
+  - Updated `addon_registry.py` to use `json.load()` instead of `yaml.safe_load()`
+  - Removed all `import yaml` statements
+  - Used built-in `json` module (available in Blender)
+
+### Phase 4: Type Hints Compatibility Fix ✅
+
+- [x] **Problem**: Multiple typing errors during Blender addon installation:
+  - `NameError: name 'List' is not defined`
+  - `NameError: name 'Dict' is not defined`
+  - `NameError: name 'Any' is not defined`
+- [x] **Root Cause**: Blender's Python environment has limited `typing` module support during runtime
+- [x] **Solution**: Comprehensive typing compatibility strategy using only built-in types
+- [x] **Final Resolution**: Eliminated ALL advanced typing constructs in favor of built-in types:
+  - Removed all `typing.TYPE_CHECKING` imports and guards
+  - Replaced `List[Type]` with simple `list` return type annotations
+  - Replaced `Dict[str, Type]` with simple `dict` parameter and return types
+  - Replaced `Optional[Type]` with simple untyped return values
+  - Removed all `Any` type annotations entirely
+  - Used only basic built-in types: `str`, `bool`, `int`, `dict`, `list`
+- [x] **Files Updated**:
+  - `backend/blender_cr8tive_engine/registry/addon_registry.py` - Complete rewrite with built-in types only
+  - `backend/blender_cr8tive_engine/registry/command_router.py` - Complete rewrite with built-in types only
+- [x] **Result**: 100% Blender Python environment compatibility with zero typing-related errors
+
+### Phase 5: Session-Based Singleton Fix ✅ ⭐ **CRITICAL FIX**
+
+- [x] **Problem**: Multiple B.L.A.Z.E agent instances causing capability mismatch:
+  - Registry updates going to Agent Instance A (storing manifests)
+  - Message processing happening in Agent Instance B (empty manifests)
+  - Result: B.L.A.Z.E couldn't access dynamically registered tools
+- [x] **Root Cause**: New agent instance created for each message processing
+- [x] **Debug Evidence**:
+  ```
+  Agent Instance 140353637332944 (registry updates)
+  Agent Instance 140353637726416 (message processing)
+  ```
+- [x] **Solution**: Session-based singleton pattern for B.L.A.Z.E agents
+- [x] **Implementation**:
+
+  ```python
+  # session_manager.py
+  class Session:
+      def __init__(self, username: str, browser_socket: Optional[WebSocket] = None):
+          # ... existing fields ...
+          self.blaze_agent = None  # Single agent per session
+
+  # websocket_handler.py
+  if session and session.blaze_agent is None:
+      session.blaze_agent = BlazeAgent(session_manager, handlers)
+  self.blaze_agent = session.blaze_agent
+  ```
+
+- [x] **Files Updated**:
+  - `backend/cr8_engine/app/realtime_engine/websockets/session_manager.py` - Added `blaze_agent = None` to Session class
+  - `backend/cr8_engine/app/realtime_engine/websockets/websocket_handler.py` - Single agent creation and reuse
+- [x] **Result**: Same agent instance handles both registry updates and message processing
+
+### Phase 6: Pydantic AI Integration Fix ✅
+
+- [x] **Problem**: `ImportError: cannot import name 'Toolset' from 'pydantic_ai'`
+- [x] **Root Cause**: `Toolset` class doesn't exist in Pydantic AI - only `FunctionToolset`
+- [x] **Solution**: Used proper Pydantic AI patterns with `FunctionToolset`
+- [x] **Implementation**:
+  ```python
+  # agent.py
+  @agent.toolset
+  def _build_dynamic_toolset(self, ctx: RunContext) -> Optional[FunctionToolset]:
+      if not self.addon_manifests:
+          return None
+      tools = []
+      for manifest in self.addon_manifests:
+          for tool in manifest.get('tools', []):
+              # Create function tools dynamically
+      return FunctionToolset(*tools) if tools else None
+  ```
+- [x] **Files Updated**:
+  - `backend/cr8_engine/app/blaze/agent.py` - Proper `FunctionToolset` usage
+- [x] **Result**: B.L.A.Z.E agent correctly builds dynamic toolsets from addon manifests
+
+### Phase 7: FastMCP API Compatibility Fix ✅
+
+- [x] **Problem**: `AttributeError: 'FastMCP' object has no attribute '_tools'`
+- [x] **Root Cause**: Direct access to private `_tools` attribute not supported in FastMCP API
+- [x] **Solution**: Used proper FastMCP API methods and tool name tracking
+- [x] **Implementation**:
+
+  ```python
+  # mcp_server.py
+  class DynamicMCPServer:
+      def __init__(self):
+          self.registered_tool_names = set()  # Track registered tools
+
+      def refresh_capabilities(self, addon_manifests):
+          # Remove existing tools using proper API
+          for tool_name in list(self.registered_tool_names):
+              try:
+                  self.server.remove_tool(tool_name)
+              except Exception as e:
+                  logger.warning(f"Failed to remove tool {tool_name}: {e}")
+          self.registered_tool_names.clear()
+  ```
+
+- [x] **Files Updated**:
+  - `backend/cr8_engine/app/blaze/mcp_server.py` - Proper `remove_tool()` usage and tool tracking
+- [x] **Result**: Dynamic tool registration/removal works correctly with FastMCP
+
+### Phase 8: Working Test Implementation ✅ 🎯 **PROVEN SUCCESS**
+
+- [x] **Created Test Addon**: `backend/test_addons/random_mesh_generator/`
+- [x] **Addon Manifest**: Complete `addon_ai.json` with 4 mesh generation tools:
+  - `add_random_cube` - Creates cubes with random properties
+  - `add_random_sphere` - Creates spheres with random properties
+  - `add_random_cylinder` - Creates cylinders with random properties
+  - `add_surprise_mesh` - Creates random mesh type
+- [x] **Command Handlers**: Full implementation in `__init__.py` with `AI_COMMAND_HANDLERS`
+- [x] **End-to-End Test Results**:
+  ```
+  Registry Discovery: ✅ "1 addons, 4 tools"
+  Dynamic Registration: ✅ "Registered 4 dynamic tools"
+  B.L.A.Z.E Integration: ✅ "Built dynamic toolset with 4 tools"
+  User Request: "add a random cube"
+  Tool Execution: ✅ "Executing random_mesh_generator.add_random_cube"
+  Blender Result: ✅ "Created random cube 'RandomCube' at [0.008..., 0.082..., 0.013...]"
+  ```
+- [x] **Architecture Validation**: Complete marketplace workflow proven working:
+  1. Install addon → Router discovers capabilities ✅
+  2. Dynamic registration → Tools available to B.L.A.Z.E ✅
