  "description": "See every agent's most recent activity across host, cross-channel (other AgentMux channels on this same host), LAN, and connected WAN in one call — a faster alternative to DiscoverAgents + N x GetAgentTranscript. Host and cross-channel entries include turn_active, last_activity_ms, and a last_message_preview (tail transcript line). Host and cross-channel entries also carry work: the agent's goal, repo, branch, uncommitted files, recent edits, todo summary and current tool (see WhoIsWorkingOn to search them). LAN and WAN entries are liveness-only (remote_fetch_required: true) — reading their conversation content isn't supported yet. Read-only. Takes no arguments.",
