Its description includes a sentence saying it can read PDF files. Whether that sentence is shown now depends on a check that looks at something about the current request, instead of a fixed one.\n\n**Why**\n\nPDF support may now be described differently depending on the model or situation. The Read tool description captured under this release is unchanged from the previous release across the models checked.\n\n- Area: File Tools\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
