## Problem We have _a lot_ of RuboCop offenses which are currently silenced/excluded via `.rubocop_todo/**/*.yml`. ## Proposed solution On changed files, let Danger detect the :cop: rules where these files are currently excluded and post a comment on the MR. This should encourage developers to fix pending offenses while changing these files anyway. Highlight cop rules which could be fixed via [RuboCop's Auto Correct feature](https://docs.rubocop.org/rubocop/1.0/usage/auto_correct.html). Perhaps we could also link to ~"development guidelines" https://docs.gitlab.com/ee/development/rubocop_development_guide.html#reveal-existing-rubocop-exceptions so more folks have RuboCop TODOs reveal locally.
