Worked on the rubocop/rubocop repository to enhance documentation for the Layout/ClassStructure cop configuration, focusing on clarifying how to enforce the order of macros and methods within Ruby class definitions. The update detailed that both ExpectedOrder and Categories must be explicitly defined for macros such as attr_reader to be properly recognized and ordered, reducing potential misconfigurations. This work involved careful code analysis and a deep understanding of RuboCop’s configuration mechanics, aiming to improve onboarding and consistency for developers. The contribution centered on Ruby and documentation skills, ensuring that project guidelines are clear and actionable for future codebase maintainers.
