Understand the Start Node

This node serves as the input point where the user can enter information to interact with the agent.
Customize My Agent
Customizing your "My Agent" node is crucial for the proper execution of your workflow. You can set various parameters to tailor the agent to your needs.
Naming your agent is the first step. Change the name to make it easier to identify. Additionally, you can give specific instructions to the agent that govern its behavior.
Instructions and Chat History

Activating chat history is also important as it helps the agent remember previous conversations and requests.
