sess start

sess start <name> [--auto-save] [--no-auto-save]

Starts a new tmux session tracked by sess, without needing to already be inside tmux. If a live tmux session with that name already exists, sess attaches to it instead of creating a duplicate.

sess start backend-debug

Auto-save

sess start backend-debug --auto-save      # force it on for this session
sess start backend-debug --no-auto-save   # force it off for this session
sess start backend-debug                  # follows [autosave] enabled in config.toml

--no-auto-save always wins if both are somehow relevant; otherwise --auto-save wins; otherwise the configured default applies. See auto-save for what the background loop actually does.
