Human as a tool

Human are AGI so they can certainly be used as a tool to help out AI agent when it is confused.

import sys
from langchain.chat_models import ChatOpenAI
from langchain.llms import OpenAI
from langchain.agents import load_tools, initialize_agent
from langchain.agents import AgentType

llm = ChatOpenAI(temperature=0.0)
math_llm = OpenAI(temperature=0.0)
tools = load_tools(
    ["human", "llm-math"], 
    llm=math_llm,
)

agent_chain = initialize_agent(
    tools,
    llm,
    agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION,
    verbose=True,
)

In the above code you can see the tool takes input directly from command line. You can customize prompt_func and input_func according to your need.
