Use this skill whenever you need to interact with tmux — sending commands to panes, reading their output, watching a TUI app like vim, htop, or lazygit, or managing sessions and windows. Reach for it any time the user says "run this in the terminal", "check that pane", "send a command to the shell", or when you spawn a background task that you'll need to monitor. Always use this skill when tmux is involved — it provides reliable pane identification, delta output reading, and safe key-sending that prevent common mistakes.
