# tmux Skill

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

## Quickstart (isolated socket, exec tool)

```bash
SOCKET_DIR="${NANOBOT_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/nanobot-tmux-sockets}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/nanobot.sock"
SESSION=nanobot-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
```

After starting a session, always print monitor commands:

```
To monitor:
  tmux -S "$SOCKET" attach -t "$SESSION"
  tmux -S "$SOCKET" capture-pane -p -J -t "$SESSION":0.0 -S -200
```

## Socket convention

- Use `NANOBOT_TMUX_SOCKET_DIR` environment variable.
- Default socket path: `"$NANOBOT_TMUX_SOCKET_DIR/nanobot.sock"`.

## Targeting panes and naming

- Target format: `session:window.pane` (defaults to `:0.0`).
- Keep names short; avoid spaces.
- Inspect: `tmux -S "$SOCKET" list-sessions`, `tmux -S "$SOCKET" list-panes -a`.

## Finding sessions

- List sessions on your socket: `{baseDir}/scripts/find-sessions.sh -S "$SOCKET"`.
- Scan all sockets: `{baseDir}/scripts/find-sessions.sh --all` (uses `NANOBOT_TMUX_SOCKET_DIR`).

## Sending input safely

- Prefer literal sends: `tmux -S "$SOCKET" send-keys -t target -l -- "$cmd"`.
