# 🎯 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 │
|
|
│ ↓ │ /api/generate │
|
|
│ GeminiCliAgent │ ↓ │
|
|
│ ↓ │ Ollama Response │
|
|
│ SSH → Gemini │ │
|
|
│ CLI Execution │ │
|
|
└─────────────────┴─────────────────┘
|
|
```
|
|
|
|
#### **Agent Registration Flow**
|
|
```
|
|
API Call → Validation → Connectivity Test
|
|
↓
|
|
Database Registration → CLI Manager Registration
|

|
|
Hive Coordinator Integration ✅
