   `--eslint-formatter-bar
  ```
  
  Convert this description:
  
  not-found-metadata is a fundamental directory that houses 3 subdirectories: no-page, page-error and slot-error.
  At the main level, 'no-page' shelters 1 subfolders: @foobar.
  Within directory hierarchy 'no-page → @foobar', The '@foobar' container has yet to be populated.
  Back to the top level.
  At the main level, 'page-error' stands empty.
  At the top level, 'slot-error' lacks any subdirectories.
