One of its figures is the size of the tool schemas. A tool schema is the description of a tool that is sent to the model so it knows the tool exists and how to use it. When a recorded list of the tools that were actually sent exists, that figure is now measured from that list.\n\n**Why**\n\nThe reported size now matches what the model was really given, not an estimate built some other way.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
