Before diving into usage, let’s define the keyword. is short for Cross-Reference . In software engineering, a cross-reference allows you to click on a symbol (function, class, variable, macro) and immediately jump to its definition, all its usages, or its references.

To a human, AOSP is a titan of code—millions of lines of C++, Java, and Rust that power billions of devices. To xref-bot-04 , it was a landscape of broken bridges that needed mending. Its job was to create the "cross-references"—the xref links—that allow a developer to click a function name and instantly see where it was born and where it was called. xref aosp
