Having established what LLM agents are and the components that make them up, this chapter transitions from theory to practice. Here, you will put that foundational knowledge to use by constructing your first simple LLM agent.

You will learn to:

• Prepare your development environment for agent creation.
• Choose an appropriate Large Language Model for a basic agent.
• Formulate instructions and define a clear goal for your agent.
• Implement a fundamental action within the agent's code.
• Execute your agent and observe its operation.
• Identify and address common initial problems.

The chapter culminates in a hands-on exercise where you will build a to-do list management agent, solidifying these practical steps.
