var nudgeCmd = &cobra.Command{
	Use:     "nudge <target> <message>",
	GroupID: GroupComm,
	Short:   "Send a message to a polecat or deacon session reliably",
	Long: `Sends a message to a polecat's or deacon's Claude Code session.

Uses a reliable delivery pattern:
1. Sends text in literal mode (-l flag)
2. Waits 500ms for paste to complete
3. Sends Enter as a separate command

This is the ONLY way to send messages to Claude sessions.
Do not use raw tmux send-keys elsewhere.

Special targets:
  deacon    Maps to the Deacon session (gt-deacon)

Examples:
  gt nudge gastown/furiosa "Check your mail and start working"
  gt nudge gastown/alpha "What's your status?"
  gt nudge deacon session-started`,
