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: linter.rb
    path of file: ./repos/byebug/tasks
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

#
# Common stuff for a linter
#
module LinterMixin
  def run
    offenses = []

    applicable_f
    
  def failure_message_for(offenses)
    msg = "#{self.class.name} detected offenses. "

    msg += if respond_to?(:fixing_cmd)
             "Run `#{fixing_cmd(offenses)}` to fix them."
           else
             "Affected files: #{offenses.join(' ')}"
           end
