Worked on the languagetool-org/languagetool repository, focusing on improving the accuracy and maintainability of English punctuation rules documentation. Addressed a documentation bug by correcting URLs for unpaired brackets and quotes, ensuring that references now point to the appropriate parentheses and quotation marks sections. This update enhanced the clarity of documentation, reducing confusion for developers and streamlining onboarding. The work involved code refactoring and careful attention to documentation standards, utilizing Java and related tooling. No new user-facing features were released during this period, as the primary emphasis was on backend quality and reducing future support overhead through improved documentation practices.
