📦 Agent 模型深度解析

# superagi/models/agent.py

class Agent(DBBaseModel):
    """Represents an agent entity."""
    
    __tablename__ = 'agents'
    
    id = Column(Integer, primary_key=True, autoincrement=True)
    name = Column(String)
    project_id = Column(Integer)
    description = Column(String)
    agent_workflow_id = Column(Integer)
    is_deleted = Column(Boolean, default=False)
    
    def fetch_configuration(cls, session, agent_id: int):
        """Fetches the configuration of an agent."""
        agent = session.query(Agent).filter_by(id=agent_id).first()
        # 获取智能体配置逻辑

Agent模型是SuperAGI的核心，定义了智能体的基本属性和行为

🔗 Agent Workflow 架构

# Agent Workflow 实现

class AgentWorkflow:
    """智能体工作流编排"""
    
    def __init__(self, name, steps=None):
        self.name = name
        self.steps = steps or []
        self.current_step = 0
        self.status = "created"
    
    def execute_step(self, step, context):
        """执行单个工作流步骤"""
        try:
            # 解析和执行工具调用
            if hasattr(step, 'tool_calls'):
                for tool_call in step.tool_calls:
                    result = self.execute_tool(tool_call, context)
                    context.update(result)
            
            # 更新步骤状态
            step.status = "completed"
            self.current_step += 1
            
        except Exception as e:
            step.status = "failed"
            raise e

Agent Workflow 实现智能体的任务编排和步骤执行逻辑

🔧 工具系统设计

# superagi/tools/base_tool.py

class BaseTool:
    """工具基类"""
    
    def __init__(self, name, description):
        self.name = name
        self.description = description
        self.schema = self._create_schema()
    
    def _create_schema(self):
        """创建工具参数模式"""
        return create_model(
            f"{self.name}Input",
            **self._get_parameters()
        )
    
    def execute(self, **kwargs):
        """执行工具逻辑"""
        raise NotImplementedError
        
    async def aexecute(self, **kwargs):
        """异步执行工具逻辑"""
        raise NotImplementedError

⚡ 执行管理器

# 执行管理器架构

class ExecutionManager:
    """任务执行管理器"""
    
    def __init__(self):
        self.celery_app = Celery('superagi')
        self.task_queue = asyncio.Queue()
        self.active_tasks = {}
    
    async def execute_workflow(self, workflow):
        """执行工作流"""
        try:
            for step in workflow.steps:
                task = await self._execute_step(step)
                self.active_tasks[step.id] = task
                await task
                
        except Exception as e:
            await self._handle_error(e)
            
    async def _execute_step(self, step):
        """执行单个步骤"""
        return asyncio.create_task(self._process_step(step))

执行管理器负责协调任务的执行，支持并发和错误处理

🔧 工具基类架构

# 工具基类设计

from abc import abstractmethod
from typing import Dict, Any, Optional

class BaseTool(BaseModel):
    """工具基类"""
    
    name: str
    description: str
    config: Optional[Dict[str, Any]] = None
    
    @abstractmethod
    def execute(self, **kwargs) -> Dict[str, Any]:
        """执行工具"""
        pass
    
    @abstractmethod
    def validate_input(self, **kwargs) -> bool:
        """验证输入参数"""
        pass
    
    def before_execute(self, **kwargs):
        """执行前处理"""
        pass
    
    def after_execute(self, result: Dict[str, Any]):
        """执行后处理"""
        pass

工具基类定义了标准化的工具接口，支持自定义验证和生命周期管理

class EventSystem:
    """事件驱动系统"""
    
    def __init__(self):
        self.event_handlers = defaultdict(list)
        self.event_queue = asyncio.Queue()
    
    def register_handler(self, event_type, handler):
        """注册事件处理器"""
        self.event_handlers[event_type].append(handler)
    
    async def emit(self, event_type, data):
        """触发事件"""
        event = Event(event_type, data)
        await self.event_queue.put(event)
        
    async def process_events(self):
        """处理事件队列"""
        while True:
            event = await self.event_queue.get()
            for handler in self.event_handlers[event.type]:
                await handler(event)
