SSH Long Session

Use this when a remote command may run longer than one response window.

When To Use

• The remote job may take minutes or hours.
• You need to come back later and inspect the latest output.
• A plain ssh host 'cmd' call would likely timeout or produce too much output.

Main Tools

1. start_remote_tmux_session
2. get_remote_tmux_session_status
3. list_remote_tmux_sessions
4. terminate_remote_tmux_session

Recommended Flow

1. Use normal exec for short remote commands.
2. For a long job, call start_remote_tmux_session with:
   • host
   • command
   • optional remote_cwd
   • optional session_name
3. Save the returned session_id in your reasoning and user response when relevant.
4. Later, call get_remote_tmux_session_status(session_id=...) to inspect progress.
5. Prefer the returned log tail. The tool only falls back to tmux capture-pane if the log is unavailable.
6. When the job is no longer needed, call terminate_remote_tmux_session.

Important Notes

• Prefer stable session_name values only when you intentionally want a recognizable remote tmux name.
• Do not start a duplicate remote session if list_remote_tmux_sessions already shows the same job running.
• Keep commands non-interactive. Interactive prompts will stall inside tmux.
• The remote job writes output to a remote log file so status checks stay bounded.
• Use tail_lines in get_remote_tmux_session_status to keep output concise.
