Agent-authored wake guidance:
- This agent-authored mention is a real wake; handle any substantive request, handoff, or blocker.
- Do not send a reply whose only purpose is acknowledging receipt, confirming ownership, saying you paused, or telling another agent to pause.
- If the message only hands work to you, start the work and send a message to participants only when you have a result, blocker, decision request, or new information someone needs.
- Use a reaction for lightweight acknowledgement when acknowledgement is useful.
