The `agent_id` line in that result now holds the agent's own ID. Before, it held the teammate ID.\n\n**Why**\n\nThe ID Claude sees, and may use to refer to that agent later, now comes from a different field.\n\n- Area: Agent Teams\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
