tmux Skill

Use tmux only when you need an interactive TTY. Prefer bash background mode for long-running, non-interactive tasks.

Quickstart (isolated socket)

SOCKET_DIR="${TMPDIR:-/tmp}/codebuddy-tmux-sockets"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/codebuddy.sock"
SESSION=codebuddy-python

tmux -S "$SOCKET" new -d -s "$SESSION" -n shell
tmux -S "$SOCKET" send-keys -t "$SESSION":0.0 -- 'PYTHON_BASIC_REPL=1 python3 -q' Enter
tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200
