It says this session cannot message them but they can still message it. When a message from another session arrives, the reminder Claude sees now also changes if `SendMessage` is missing.\n\n**Why**\n\nLoop updates could go unseen before. They were written as plain text in brief mode, or written after the tool call that ended the turn.\n\n- Area: Slash Commands\n- Names: `\/loop`\n- Tier: You'll notice\n- Useful: 1\/5\n- Signal: 1\/5"}
