When the reply to a shutdown request was anything other than success, Claude Code used to record it as a failed write to the agent's mailbox. A refused shutdown is now recorded as a refusal instead.\n\nAgents that are resumed, or that are still running, now also receive script markers.\n\n**Why**\n\nThe usage data Claude Code records about agent messaging is more accurate: a refusal is no longer counted as a delivery failure.\n\n- Area: Agent Teams\n- Names: `SendMessage`\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5\n- Scope: individual\n- Heads-up: no"}
