cmux Core Control Use this skill to control non-browser cmux topology and routing. Core Concepts Window: top-level macOS cmux window. Workspace: tab-like group within a window. Pane: split container in a workspace. Surface: a tab within a pane (terminal or browser panel). Fast Start

attention cue

cmux trigger-flash --surface surface:7 Handle Model Default output uses short refs: window:N , workspace:N , pane:N , surface:N . UUIDs are still accepted as inputs. Request UUID output only when needed: --id-format uuids|both .
