      If the current directory is a project directory (i.e. contains a
      Guild file), the command shows operations defined for the
      project. Otherwise, the command shows operations defined in
      installed packages.
  
      Note that operations defined in packages are always available to
      run, even when running within a project directory. To always show
      installed operations, use the `--installed` option.
  
      Use one or more `FILTER` arguments to show only operations with
      names or models that match the specified values.
