show_hooks

List configured tmux hooks at the given scope.

scope="server" enumerates hooks installed via tmux set-hook -g .... tmux splits those globals across two options trees by hook category: session-level hooks (session-closed, client-*, etc.) live in the global-session tree enumerated by show-hooks -g, while pane/window-level hooks (pane-focus-in, window-resized, etc.) live in the global-window tree enumerated by show-hooks -gw. This tool consults both trees and merges the results so the enumeration matches what a name-targeted :func:~libtmux_mcp.tools.hook_tools.show_hook call would return.

Default: null.
socket_name optional: tmux socket name.
Default: null.
