+description: >
+  Raises a persistent Monitor (Monitor tool, NOT background Bash) on the
+  project's `.claude-inbox/` at the start of an interactive session, so
+  inter-session messages page the session in real time; the monitor dies on
+  session end on its own. A paired SessionStart hook injects the
+  raise-instruction and first sweeps orphaned monitors of this inbox (a
+  `/clear` leaves them running → re-raise would stack duplicates). Triggers:
+  CLAUDE.md line `inbox monitor: raise on start`, or «подними монитор почты»,
+  «настрой авто-монитор инбокса», «raise inbox monitor», «auto-arm inbox
+  watcher». Headless (`claude -p`): does NOT raise — Monitor doesn't work
+  there; rely on the Stop-hook inbox pickup + Notify/ntfy. NOT for how to
+  handle a received message (→ inter-session-peer-discipline) nor the
+  multi-machine inbox backend (→ cross-machine-inbox design).

+# session-inbox-monitor
+
+Auto-raises a session-length Monitor on `.claude-inbox/` at interactive-session
+start (via a paired SessionStart hook that injects the instruction and sweeps
+orphans), so inter-session messages page the session in real time. Tears down
+for free on session end. Headless sessions skip it and rely on the pull-model
+(Stop-hook pickup + Notify).
