Instructions

  • Define the graph state using the GraphState class, with a single attribute called messages.
  • Define the agent node that reads the messages attribute of the graph state, invokes the llm_with_tools with the messages, and appends the result to the messages attribute of the graph state.
  • Define the tool node that reads the tool_calls attribute of the most recent message in the graph state, extracts the name of the tool to execute (name), invokes it with the arguments (args) of the tool call, and appends the result to the messages attribute of the graph state.
  • Initialize the graph using the StateGraph class in LangGraph, with the graph state (GraphState) we defined previously.
  • Add the nodes and edges to the graph and compile it.
