Worked on linter improvements for the oxc-project/oxc repository, focusing on React Hooks validation by refining rule logic to reduce false positives and align more closely with ESLint standards. Enhanced the linter to recognize custom hook names with digits and improved dependency analysis for useMemo patterns, using JavaScript, Rust, and linter development expertise. In the zed-industries/extensions repository, integrated the Karma Theme as a git submodule, updated configuration files in TOML, and ensured version alignment with the upstream theme. This work established a repeatable process for external theme integration and improved configuration management practices within the Zed extension registry.
