What problem does it solve? Operators running many agent sessions across multiple machines and harnesses lose track of who is alive, where each session lives, and how to reach it. This Skill performs a full fleet roll call so no session is missed or double-counted. ## Core Features & Use Cases - Three-source enumeration: Queries the director bus roster, every marvel cluster's sessions, and Claude SendMessage ListAgents, since each source sees sessions the others miss. - Identity deduplication: Collapses sessions appearing in multiple sources into one row using agent name, instance ULID, tmux target, or title as match keys. - Reach-method precedence: Records the highest layer that can actually reach each session, from director bus messages down through marvel inject, tmux, and SendMessage. - Extended relay forms: After enumerating, relays a directive such as harvest, prepare-to-shutdown, status update, or liveness check to all live seats and reports message IDs and replies. - Use Case: You ask "stansfield, get updates from everyone" and receive one deduped table of all sessions across hosts with their health, chosen reach layer, and each seat's status reply. ## Quick Start Ask the agent to run a stansfield roll call to enumerate every session across the fleet and report each one's reachability.
