BabyAGI implementation with tools with multiple inputs (requiring Structured Tool Chat Agent)

[toadFrogski]

Discussed in https://github.com/langchain-ai/langchain/discussions/5410

^{Originally posted by **luca-git** May 29, 2023} My goal is to extend the tools used by baby AGI, more specifically to use at least the basic WriteFileTool() and ReadFileTool(). They use two inputs though, so I cannot stick with the vanilla ZeroShotAgent. So i resorted to using: AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION and replace it in the original code in the link below. Agent initialization is the only modification I've made. Can anyone kindly help me understand what I'm missing in the code in order to be able to leverage multiple input tools or provide guidance/resources? https://python.langchain.com/en/latest/use_cases/agents/baby_agi_with_agent.html?highlight=babyagi%20with%20tools ```python from langchain.agents import AgentType from langchain.agents import initialize_agent @classmethod def from_llm( cls, llm: BaseLLM, vectorstore: VectorStore, verbose: bool = False, **kwargs ) -> "BabyAGI": """Initialize the BabyAGI Controller.""" task_creation_chain = TaskCreationChain.from_llm(llm, verbose=verbose) task_prioritization_chain = TaskPrioritizationChain.from_llm( llm, verbose=verbose ) llm_chain = LLMChain(llm=llm, prompt=prompt) tool_names = [tool.name for tool in tools] agent = initialize_agent(agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,llm=llm_chain, tools=tool_names) agent_executor = AgentExecutor.from_agent_and_tools( agent=agent, tools=tools, verbose=True ) return cls( task_creation_chain=task_creation_chain, task_prioritization_chain=task_prioritization_chain, execution_chain=agent_executor, vectorstore=vectorstore, **kwargs, ) ``` I get the error ```python File ~\anaconda3\envs\aagi\lib\site-packages\langchain\agents\structured_chat\base.py:83 in create_prompt args_schema = re.sub("}", "}}}}", re.sub("{", "{{{{", str(tool.args))) AttributeError: 'str' object has no attribute 'args' ```

Hi, @toadFrogski! I'm Dosu, and I'm helping the LangChain team manage our backlog. I wanted to let you know that we are marking this issue as stale.

Based on my understanding, you are trying to extend the tools used by BabyAGI to include WriteFileTool() and ReadFileTool(), which require multiple inputs. You encountered an error related to the 'args' attribute and sought guidance on modifying the code to leverage multiple input tools. There has been a response from me suggesting to look at related open issues for possible solutions.

Before we close this issue, we wanted to check if it is still relevant to the latest version of the LangChain repository. If it is, please let us know by commenting on the issue. Otherwise, feel free to close the issue yourself, or it will be automatically closed in 7 days.

Thank you for your contribution to the LangChain repository!
