Focus on the most essential components (such as core data sources and integrations), and install the XDR agent (subject to license) as the central sensor for visibility and prevention. This establishes the Cortex Extended Data Lake (XDL) as the central data repository, ensuring it is the single, intelligent source of truth powering all subsequent XQL queries, detection analytics, and automated case triage. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://cortex-docs.paloaltonetworks.com/cortex-xsiam/onboard-cortex-xsiam/onboard-cortex-xsiam.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. 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.
