Before, for a PDF small enough to read in one go, that note told Claude to read the whole file. That instruction has been removed.\n\n**Why**\n\nThis changes the guidance Claude follows for attached PDFs, so it may read them differently than before.\n\n- Area: Elsewhere\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
