Remote-control tmux sessions for interactive CLIs by sending keystrokes and scraping pane output.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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="${LEMON_TMUX_SOCKET_DIR:-${TMPDIR:-/tmp}/lemon-tmux-sockets}"
mkdir -p "$SOCKET_DIR"
SOCKET="$SOCKET_DIR/lemon.sock"
SESSION=lemon-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 `LEMON_TMUX_SOCKET_DIR` for socket location.
- Default socket path: `"$LEMON_TMUX_SOCKET_DIR/lemon.sock"`.
## Targeting panes and naming
- Target format: `session:window.pane` (defaults to `:0.0`).
- Keep names short; avoid spaces.
- Inspect: `tmux -S "$SOCKET" list-sessions`, `tmux -S "$SOCKET" list-panes -a`.
## Finding sessions
- List sessions on your socket: `{baseDir}/scripts/find-sessions.sh -S "$SOCKET"`.

How to install
mdr add z80dev/lemon/tmux@sha256:1d7c2409e1cea6a6The line at the top of this page pins the label git:20260214.21456e2, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
