Use when the user asks "why was this cop added/removed", "find upstream PR for a cop", "trace cop change in Rails", "what's the reason for this cop", or wants to find the rails/rails PR or commit that introduced or removed a specific RuboCop cop.

This skill should be used when the user asks to "check config diff", "compare upstream config", "diff rubocop config", "sync with Rails rubocop", or wants to see differences between the upstream Rails .rubocop.yml and this repository's config/rails.yml.
