Three things changed:\n\n- Stopped agents: messages to some agents that were stopped or cleared away now get the reply that the agent \"was stopped by the user and was not resumed\". Before, only agents stopped directly by the user got this reply.\n\n- Plugins: a plugin can now refuse to resume an agent.\n\n- Queued messages: when a message is queued for a running agent, the reply can add that if the agent finishes first it is resumed with the message and reports back, so Claude should wait for that rather than send again.\n\n**Why**\n\nClaude is less likely to send the same message twice, and it is told plainly when an agent you stopped will not pick work back up.\n\n- Area: Subagents\n- Names: `SendMessage`\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
