If you want to use this gem to check other gems quality, you will have to put following things in your gem Rakefile:

require 'bundler'
require 'rake'
require 'polishgeeks-dev-tools'

desc 'Self check using command maintained in this gem'
task :check do
  PolishGeeks::DevTools.setup do |config|
    # Any config option you want to disable/enable
    config.brakeman = false


task default: :check

And then from command line, run:

bundle exec rake
