You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: app_task.rb
    path of file: ./repos/gitlabhq/lib/system_check/rake_task
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module SystemCheck
  module RakeTask
    # Used by gitlab:app:check rake task
    module AppTask
      extend RakeTaskHelpers

      def self.name
        'GitLab App'
      end
