For example, a tool could be to excute a query with the duckduckgo search engine. *Configuration Parameters*: - `name` (str): The name of the flow. Default: "search" - `description` (str): A description of the flow. This description is used to generate the help message of the flow. Default: "useful when you need to look for the answer online, especially for recent events." - `keep_raw_response` (bool): If True, the raw response of the tool is kept. Default: False - `clear_flow_namespase_on_run_end` (bool): If True, the flow namespace is cleared at the end of the run. Default: False - `backend` (Dict[str, Any]): The configuration of the backend. Default: langchain.tools.DuckDuckGoSearchRun - Other parameters are inherited from the default configuration of AtomicFlow (see AtomicFlow) *Input Interface*: - `query` (str): the query to run the tool on *Output Interface*: - `observation` (str): the observation returned by the tool **Arguments**: - `backend` (`BaseTool`): The backend of the flow. It is a tool that is run by the flow. (e.g. duckduckgo search engine) - `\**kwargs`: Additional arguments to pass to the flow. See :class:`flows.base_flows.AtomicFlow` for more details. #### instantiate\_from\_config ```python @classmethod def instantiate_from_config(cls, config: Dict[str, Any]) -> LCToolFlow ``` This method instantiates the flow from a configuration file **Arguments**: - `config` (`Dict[str, Any]`): The configuration of the flow. **Returns**: `LCToolFlow`: The instantiated flow. #### run ```python def run(input_data: Dict[str, Any]) -> Dict[str, Any] ``` This method runs the flow. It runs the backend on the input data. **Arguments**: - `input_data` (`Dict[str, Any]`): The input data of the flow. **Returns**: `Dict[str, Any]`: The output data of the flow.
