# Giving your agents Tools Tools (or previously called Functions in the LLMs) are critical to giving your agents access to the information they need to execute the tasks you give them. Some examples might include: * Searching the web * Talking to your HRIS * Generating a PDF Tools are powerful because they allow you to expand what the LLM knows leveraging code and talking to your own systems via APIs. As part of the SDK, we have provided common tools for working with Word, PDF and other common file formats. We also have provided [built-in talent agents and tools](/guides/getting-started-with-the-talent-agent-sdk/built-in-talent-agents.md) for working with your HRIS and other common talent workflows. Let's take a look at how to build a simple tool. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.peoplelogic.dev/guides/getting-started-with-the-talent-agent-sdk/giving-your-agents-tools.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
