Introduction to Reasoning › Building on Reasoning

You now understand how to get your AI agent to think through problems step by step. That capability helps it handle complex, multi-step challenges instead of relying on a single pattern-matching response.

In the next chapter, we'll explore how to extend your agent's abilities even further by giving it access to external tools. You'll learn how an agent can recognize when it needs help, call a calculator or search function, and integrate that information into its reasoning. The combination of reasoning and tool use creates agents that are both thoughtful and capable.
