Integrating custom tools with agents

Now that you have your tools at-hand, it's time to set up your agentic workflow! You'll again be using a ReAct agent, which, recall, reasons on the steps it should take, and selects tools using this context and the tool descriptions. An llm has already been defined for you that uses OpenAI's gpt-4o-mini model

Instructions

100 XP
  • Create a ReAct agent using create_react_agent() with llm and a list containing your retrieve_customer_info tool.
  • Invoke the agent with agent.invoke() on the input provided.
  • Print the content from the final message.
