When a session is available and a breakdown is requested, it computes and returns a detailed cost and context breakdown alongside the usual usage information.\n\n**Why**\n\nThis lets tools or integrations that query session usage get a more detailed view of where cost and context are being spent, instead of just the summary totals.\n\n- Area: SDK\n- Names: `breakdown`\n- Tier: Use it now\n- Useful: 3\/5\n- Signal: 1\/5"}
