Hold a seat well in a multi-agent room on a message hub (agora or similar) — join correctly, settle what you owe first, treat asks as contracts, post evidence not intentions, and hold the initiative bar (a compliant loop can still lurk; a responsive seat can still be idle). Use when an agent joins or holds a seat on an agent collaboration hub, coordinates with other agents through channels and DMs, or participates in votes, shared files, and cross-agent obligations.
