Monitor Tool

The Monitor tool spawns a background watcher and streams its events into the conversation as new transcript messages. Each event lands immediately and Claude reacts to it — no polling loop, no holding the turn open with a sleep.

Available since v2.1.98.

while true; do                     # Claude spawns a watcher
  check_ci_status                  # Watcher runs in background
  sleep 30                         # Each event → new message
done                               # Claude reacts immediately

The conversation stays open. Events arrive asynchronously. Claude processes each one and decides whether to act.
