openmanus 使用工具

mauns 默认集成4个工具

• PythonExecute()：代码执行工具，重写execute，exec执行输入code
• BrowserUseTool()：浏览器操作工具，重写execute，使用web引擎执行搜索、下拉、网页解析等工具，提取检索内容
• StrReplaceEditor()：文件操作工具，重写execute，执行查看、创建、验证、修改文件的操作
• Terminate()：任务终止工具，重写execute，输出任务终止提示

    # Add general-purpose tools to the tool collection
    available_tools: ToolCollection = Field(
        default_factory=lambda: ToolCollection(
            PythonExecute(), BrowserUseTool(), StrReplaceEditor(), Terminate()
        )
    )

各工具对抽象基类进行重写

class BaseTool(ABC, BaseModel):
    name: str
    description: str
    parameters: Optional[dict] = None

    class Config:
        arbitrary_types_allowed = True

    async def __call__(self, **kwargs) -> Any:
        """Execute the tool with given parameters."""
        return await self.execute(**kwargs)

    @abstractmethod
    async def execute(self, **kwargs) -> Any:
        """Execute the tool with given parameters."""

    def to_param(self) -> Dict:
        """Convert tool to function call format."""
        return {
            "type": "function",
            "function": {
                "name": self.name,
                "description": self.description,
                "parameters": self.parameters,
            },
        }
