snapshot_pane
Read pane output; accepts no client-supplied executable input. Returned content may be sensitive or untrusted. Read a pane’s visible content together with its cursor position, size and running command, in one call. Prefer this over capture_pane plus list_panes: it is one round trip and the cursor is guaranteed to describe the text returned with it.
