Before this change, only a large page count or file size made Claude Code use a reference. Now it also uses a reference when the model in use cannot take a whole PDF.\n\n**Why**\n\nThis stops Claude Code from sending whole PDFs to models that would reject them.\n\n- Area: Attachments\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
