Worked on the tree-sitter/tree-sitter repository to address inconsistencies in highlight name usage between the CLI documentation and the internal theme implementation. Focused on harmonizing highlight names by updating both the default theme and associated tests, ensuring that newly added or reordered names were consistently reflected across documentation, CLI, and runtime. This approach reduced user confusion and improved the reliability of highlighting configurations. Demonstrated skills in CLI development, documentation, and Rust, with an emphasis on patch alignment and test-driven updates. The work enhanced maintainability by aligning code and documentation, while expanding test coverage to support ongoing theme definition changes.
