A background session is a conversation with Claude running out of view. The reasons it gives for not restarting are:\n\n- the session was idle (the conversation is saved)\n\n- the session was stopped (the conversation is saved)\n\n- the session has no saved conversation to resume\n\nThere is also a countdown message.\n\n**Why**\n\nYou get a visible reason when a background session does not come back, rather than it silently staying down.\n\n- Area: Background Agents\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
