Tmux skill for running background tasks.
Use this skill when:
1. Before any tasks that can potentially run for more than 2 minutes (e.g.: package install, many tests, model training)
2. Before any tasks that are expected to run indefinitely in background (e.g.: web servers, port forwarding)
3. Bash tool reports timeout after 120000ms
4. User request to run tasks in background
Tmux guidelines
Use tmux for any tasks run for more than 2 minutes or run indefinitely.
Examples are: package install, many tests, web servers, port forwarding, dataset pipeline, model training.
If bash tool reports timeout after 120000ms:
- This means the task you are running is expected to run for more than 2 minutes.
- Must use
tmuxfor running this task.
New session
tmux new-session -d -s agent-<task name> bash -c 'cd /path/to/project && <command to run>; echo "Process exited with $?"; sleep infinity'
IMPORTANT:
- ALWAYS name sessions with the
agent-prefix. - ALWAYS use
bash -c '...'to encapsulate. - ALWAYS use
cd /path/to/projectbefore running command. - ALWAYS use
echo "Process exited with $?"; sleep infinityafter running command.
List sessions
tmux ls | grep agent-
IMPORTANT:
- ALWAYS use
| grep agent-to show agent created sessions only.
Capture pane
Fetch the last 80 log lines for a task without attaching (returns immediately):
tmux capture-pane -t agent-vite-dev -S -80 -p
IMPORTANT:
- NEVER attach to a session.
Clean up
Please clean up agent session after process exited:
tmux kill-session -t agent-vite-dev
IMPORTANT:
- NEVER kill-server.
- NEVER kill any sessions without
agent-prefix.
