rubocop-kata

https://github.com/giacope/rubocop-kata

Bundles a curated RuboCop stack (rspec, performance, elegant, packaging, thread_safety) behind one dependency, layers opinionated style defaults on top, and adds fifteen cops of its own — naming (GoodMethodName, GoodVariableName, dictionary-backed RealWords, AgentNoun, BuilderNoun, NoUtilName), discipline (IoDiscipline, ClockDiscipline, EnvDiscipline, ConstructorDiscipline, NoClassMethodLogic), and shape (NoComments, NoBooleanFlag, NoHashAsObject, ProsePlacement). The rubocop-kata command reports dead configuration (doctor), buckets a backlog into the stages that cause each other (plan), and prints an agent skill for working it (skill).
