During June 2025, contributed to the swiftlang/swift-syntax repository by developing the Trivia.docCommentValue feature, which extracts and sanitizes documentation comments within Swift code. This work focused on improving the reliability of doc-comment processing, enabling cleaner API documentation and supporting downstream tooling. The implementation involved extending the Trivia API, leveraging Swift for abstract syntax tree traversal and text sanitization, and applying code refactoring techniques to standardize comment handling. Emphasis was placed on maintainability and code quality, with unit testing ensuring robust functionality. The contribution addressed a specific need for more consistent documentation extraction, enhancing the overall developer experience for Swift projects.
