[ Message this agent…            Send ]
[ Stop ]  [ Back ]

• /atc opens the pane and gives it the keyboard. Esc hands the keyboard back. /atc close closes it.
• 1–9 picks an agent. Its trail, model, call count and tokens show below the list.
• Message sends text to the picked agent. A finished agent is resumed with it, so you can ask a follow-up.
• Stop stops a running background agent or teammate (TaskStop, with the teammate's own id).
• Quiet means running with no tool call for 90s. It is usually stuck on a permission prompt or a long command.
• The status line shows agent-atc: N running whenever any are running. A waiting agent (on its own background work, a plan approval or a child agent) counts as running; an idle teammate doesn't.

Setting autoOpen (default on) opens the pane by itself when the first subagent starts. This only happens on terminals 144+ columns wide. Closing it yourself keeps it closed until you run /atc.
