+# 🎯 Phase 3 Completion Summary
+
+**Phase**: Backend Integration for CLI Agents  
+**Status**: ✅ **COMPLETE**  
+**Date**: July 10, 2025
+
+## 📊 Phase 3 Achievements
+
+### ✅ **Core Backend Extensions**
+
+#### 1. **Enhanced Agent Type System**
+- Extended `AgentType` enum with CLI agent types:
+  - `CLI_GEMINI` - Direct Gemini CLI agent
+  - `GENERAL_AI` - General-purpose AI reasoning
+  - `REASONING` - Advanced reasoning specialization
+- Updated `Agent` dataclass with `agent_type` and `cli_config` fields
+- Backward compatible with existing Ollama agents
+
+#### 2. **Database Model Updates**
+- Added `agent_type` column (default: "ollama")
+- Added `cli_config` JSON column for CLI-specific configuration
+- Enhanced `to_dict()` method for API serialization
+- Created migration script: `002_add_cli_agent_support.py`
+
+#### 3. **CLI Agent Manager Integration**
+- **File**: `backend/app/cli_agents/cli_agent_manager.py`
+- Bridges CCLI agents with Hive coordinator
+- Automatic registration of predefined agents (walnut-gemini, ironwood-gemini)
+- Task format conversion between Hive and CLI formats
+- Health monitoring and statistics collection
+- Proper lifecycle management and cleanup
+
+#### 4. **Enhanced Hive Coordinator**
+- **Mixed Agent Type Support**: Routes tasks to appropriate executor
+- **CLI Task Execution**: `_execute_cli_task()` method for CLI agents
+- **Ollama Task Execution**: Preserved in `_execute_ollama_task()` method
+- **Agent Registration**: Handles both Ollama and CLI agents
+- **Initialization**: Includes CLI agent manager startup
+- **Shutdown**: Comprehensive cleanup for both agent types
+
+#### 5. **Agent Prompt Templates**
+- Added specialized prompts for CLI agent types:
+  - **CLI_GEMINI**: General-purpose AI assistance with Gemini capabilities
+  - **GENERAL_AI**: Multi-domain adaptive intelligence
+  - **REASONING**: Logic analysis and problem-solving specialist
+- Maintains consistent format with existing Ollama prompts
+
+### ✅ **API Endpoints**
+
+#### **CLI Agent Management API**
+- **File**: `backend/app/api/cli_agents.py`
+- **POST** `/api/cli-agents/register` - Register new CLI agent
+- **GET** `/api/cli-agents/` - List all CLI agents  
+- **GET** `/api/cli-agents/{agent_id}` - Get specific CLI agent
+- **POST** `/api/cli-agents/{agent_id}/health-check` - Health check
+- **GET** `/api/cli-agents/statistics/all` - Get all statistics
+- **DELETE** `/api/cli-agents/{agent_id}` - Unregister CLI agent
+- **POST** `/api/cli-agents/register-predefined` - Auto-register walnut/ironwood
+
+#### **Request/Response Models**
+- `CliAgentRegistration` - Registration payload validation
+- `CliAgentResponse` - Standardized response format
+- Full input validation and error handling
+
+### ✅ **Database Migration**
+- **File**: `alembic/versions/002_add_cli_agent_support.py`
+- Adds `agent_type` column with 'ollama' default
+- Adds `cli_config` JSON column for CLI configuration
+- Backward compatible - existing agents remain functional
+- Forward migration and rollback support
+
+### ✅ **Integration Architecture**
+
+#### **Task Execution Flow**
+```
+Hive Task → HiveCoordinator.execute_task()
+    ↓
+    Route by agent.agent_type
+    ↓
+    ┌─────────────────┬─────────────────┐
+    │   CLI Agent     │  Ollama Agent   │
+    │                 │                 │
+    │ _execute_cli_   │ _execute_       │
+    │ task()          │ ollama_task()   │
+    │       ↓         │       ↓         │
+    │ CliAgentManager │ HTTP POST       │

+    │ GeminiCliAgent  │       ↓         │
+    │       ↓         │ Ollama Response │
+    │ SSH → Gemini    │                 │
+    │ CLI Execution   │                 │
+    └─────────────────┴─────────────────┘

+
+#### **Agent Registration Flow**
+```
+API Call → Validation → Connectivity Test
+    ↓
+Database Registration → CLI Manager Registration
