Inter-agent collaboration via the A2A 1.0 protocol. Loads when the user mentions a2a, broadcast, FYI to peer, "another agent", inbox, or proactive cross-project coordination. Teaches Claude when to poll the inbox, how to send proactive FYI messages on contract changes, and how to address peers by name.
