It now does this only when either of these is true:\n\n- the tool's input has no explicit schema (a fixed description of what the input looks like)\n\n- the tool's schema includes a `citations` field\n\n**Why**\n\nThis avoids sending a citations setting to a tool that does not support it.\n\n- Area: Tools\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
