With a solid understanding of creating and integrating basic tools, we now turn to developing more specialized and advanced functionalities. This chapter provides practical guidance on building several types of sophisticated tools.

You will learn to construct tools that allow Language Models to:

• Interpret and execute code, with a strong emphasis on secure sandboxing.
• Browse the web and extract specific information from web pages.
• Perform file system operations, such as reading and writing files, securely.
• Interact with user interfaces or solicit human input for complex or sensitive decisions.
• Generate well-formed structured data, like JSON or CSV.

These advanced toolsets significantly expand an agent's capacity to handle a broader spectrum of tasks and interact more dynamically with its environment.
