cmux（cmux 控制）

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

Settings and Docs

Use cmux docs settings before changing cmux-owned settings. It prints the docs URL, schema URL, raw GitHub resources, settings file paths, and reload command.

cmux-owned settings live in ~/.config/cmux/settings.json, with ~/Library/Application Support/com.cmuxterm.app/settings.json as the fallback. Before editing, copy any existing settings file to a timestamped .bak next to it so the user can revert. Edit the user file, then reload:

cmux reload-config

Use cmux settings for app behavior, sidebar, notifications, browser behavior, automation, workspace colors, and cmux-owned shortcuts. Terminal rendering settings such as font, cursor style, theme, and scrollback belong in Ghostty config.

Open the UI when useful:

cmux settings json
cmux settings shortcuts

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.
