cmux

name	cmux
description	End-user control of cmux topology and routing (windows, workspaces, panes/surfaces, focus, moves, reorder, identify, trigger flash). Use when automation needs deterministic placement and navigation in a multi-pane cmux layout.

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

# identify current caller context
cmux identify --json

# list topology
cmux list-windows
cmux list-workspaces
cmux list-panes
cmux list-pane-surfaces --pane pane:1

# create/focus/move
cmux new-workspace
cmux new-split right --panel pane:1
cmux move-surface --surface surface:7 --pane pane:2 --focus true
cmux reorder-surface --surface surface:7 --before surface:3

# 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.
