Use within an agent:

from langchain_openai import ChatOpenAI
from langgraph.prebuilt import create_react_agent

llm = ChatOpenAI(model="gpt-4o-mini")
agent_executor = create_react_agent(llm, tools)

example_query = "Create a task to review the quarterly report"
events = agent_executor.stream(
    {"messages": [("user", example_query)]},
    stream_mode="values",
)
for event in events:
    event["messages"][-1].pretty_print()

This toolkit contains tools that can read and modify the state of a service. For example, it can create, update, and delete tasks on behalf of the associated account.
