description	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 tmux for 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/project before running command.
• ALWAYS use echo "Process exited with $?"; sleep infinity after 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.
