How does Claude step outside its fixed training data to interact with the world? In this episode, we trace the step-by-step tool loop—the ask, act, return cycle that lets Claude search the live web, read pages, and manipulate local files. We examine the fixed knowledge cutoff date and explain why stale training facts sound just as confident as fresh ones. Finally, learn how to enforce exact quotes, verify citations, and write standing rules that ensure online searches remain accurate.
