Something I've been meaning to build for a long time. Uses Claude Code hooks (Notification and Stop events) to shoot you native notifications when your input is needed, or when Claude Code has finished and is awaiting further instructions.
Supports tmux out of the box: clicking a notification focuses your terminal and chains tmux commands to bring you back to the exact pane that spawned the notification.
Notifications are suppressed if you're already focused on that specific pane.
