# cmux Customization Use this skill for user-facing cmux customization. Keep the user's config intact, prefer schema-backed edits, and validate before reporting completion. ## What Can Be Customized - Custom actions: define reusable `actions` in `cmux.json`. Actions can appear in Cmd+Shift+P, surface tab bars, shortcuts, and the plus-button right-click menu. - New workspace button: set `ui.newWorkspace.action` to replace the normal plus-button click, and `ui.newWorkspace.contextMenu` to control right-click actions. `ui.newWorkspace.rightClick` is accepted as an alias, but new examples should use `contextMenu`. - Surface tab bar buttons: set `ui.surfaceTabBar.buttons` to replace the default tab bar buttons. Include built-in IDs such as `cmux.newTerminal`, `cmux.newBrowser`, `cmux.splitRight`, and `cmux.splitDown` only when they should stay visible. - Workflows and layouts: use `commands` with workspace definitions to open a worktree, multiple checkouts, local services, browser previews, or SSH sessions in a deliberate split layout. - Dock controls: create `.cmux/dock.json` or `~/.config/cmux/dock.json` for right-sidebar terminal controls such as logs, test watchers, git TUIs, dev servers, queues, or `cmux feed tui --opentui`. - Sidebar and app behavior: use `cmux-settings` for supported settings such as appearance, sidebar display, notification behavior, browser routing, automation, shortcuts, and new-workspace placement. - Workspace metadata: use the cmux CLI or `cmux-work
