They now simply suggest sending the running subagent a message via `SendMessage` if you need a progress report.\n\n**Why**\n\nThis simplifies the guidance shown in this situation to a single, consistent way of checking on a running subagent's progress.\n\n- Area: Elsewhere\n- Names: `SendMessage`\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 0\/5"}
