Use when you want live visibility into which agent sessions are running, which are dead, which have stale YAML entries, and which have new session ids that haven't been recorded yet. Designed to be dispatched as a Kanban goal_mode task (--goal) so it keeps running until the user stops it."

-1. Read .hermes/agent-sessions.yaml
+1. Read .mam/agent-sessions.yaml
 2. Run `tmux ls` and `tmux list-panes -F 'session=#{session_name} pid=#{pane_pid} cmd=#{pane_current_command} cwd=#{pane_current_path}'`
 3. For each session in the YAML, check the corresponding tmux state
 4. For each tmux session matching `*-creator-claude` or `*-creator-agy` that's not in the YAML, register it
