Make cmux fit your terminal workflow.
Customizes cmux viewers, terminal preferences, actions, and workspace layouts while preserving existing configuration.
When to use it
Use when changing cmux settings, commands, workspace layouts, interface controls, shortcuts, or Ghostty-backed terminal preferences.
Give it a cmux customization request; it edits the appropriate configuration, validates it, reloads cmux, and verifies the result.
Uses the cmux CLI to inspect the shipped workflow catalog and reload configuration.
Requires the cmux-settings helper for app settings and cmux-owned shortcut changes.
