Worked on the biomejs/biome repository to enhance accessibility linting for web components, focusing on reducing false positives and improving developer experience. Developed a feature that excludes custom elements from accessibility checks, allowing for more accurate linting results and minimizing unnecessary CI feedback. The technical approach involved refining lint rules, specifically targeting the a11y/noStaticElementInteractions rule, to better support custom elements commonly used in modern JavaScript and Rust projects. By addressing these issues, the work enabled faster and clearer CI feedback, supporting teams working with accessibility and linting in complex web applications. No bug fixes were recorded during this period.
