Cmux Skills

Comprehensive cmux CLI usage guide. Use when the user asks about cmux CLI, cmux --help, socket commands, command discovery, workspaces, panes, surfaces, browser CLI, hooks, feed, settings, or automation through the cmux command.

Interpret pasted cmux workspace, pane, surface, or window refs and IDs. Use for cmux-ref, cmux-id, workspace_ref, workspace_id, pane_ref, pane_id, surface_ref, surface_id, window_ref, or window_id context blocks.

Use cmux Cloud machines through the CLI. Use when the user says cmux cloud, cloud VM, cloud machine, cmux vm, Base workspace, machines panel, run/exec on a cloud machine, cloud agent, vm snapshot/fork/restore, push/pull files to a VM, open a port or desktop on a machine, or notify from inside a VM.

Configure cmux through ~/.config/cmux/cmux.json: settings (appearance, sidebar, notifications, automation, browser, shortcuts, set/get/validate by JSON path), customization (tab bar buttons, plus-button click and right-click menus, custom actions/commands/menus, right sidebar), and sidebar workspace groups (anchor workspaces, group CLI/socket ops, per-cwd group config). Triggers: 'cmux config', 'cmux.json', 'change cmux setting', 'set <x> in cmux', 'rebind a cmux shortcut', 'cmux-customize', 'customize cmux', 'tab bar button', 'add cmux action', 'workspace group', 'group sidebar', 'anchor workspace', 'workspaceGroups'.

Automate the browser inside cmux. Use for cmux browser, browser surface, webview, current workspace browser, snapshot refs, DOM actions, waits, screenshots, cookies, storage, tabs, downloads, console, errors, and browser session state.

Create durable HTML walkthrough artifacts for cmux dogfood, verification, demos, evidence pages, artifact previews, and open helpful tabs or splits in the current cmux workspace.

Set up the cmux<>Freestyle integration by building a Freestyle VM snapshot that matches the cmux Cloud VM image. Use when the user asks to bring up cmux Cloud VMs on their own Freestyle account, mint a self-serve FREESTYLE_SANDBOX_SNAPSHOT, build a cmuxd-remote Freestyle snapshot from scratch, run the standalone cmux-freestyle setup script, or iterate on the manaflow-ai/cmux-freestyle repo.

Work inside the current cmux workspace and terminal. Use for cmux workspace, current workspace, caller surface, panes, surfaces, tagged reloads, socket targeting, and non-interfering cmux automation.

Build, inspect, or revise cmux custom sidebar views using the runtime SwiftUI-style interpreter. Use for sidebar vibe coding, custom sidebars in Bonsplit panes, left sidebar picker previews, interpreted Swift sidebars, ~/.config/cmux/sidebars/*.swift, cmux docs sidebars, or Aziz's Swift interpreter work.
