Thomas Brunet contributed to the act-rules/act-ruleshub.io.git repository by enhancing accessibility documentation and refining glossary definitions. Over two months, he clarified the definition of “focusable” elements in the Accessibility Glossary, specifying behavior for regaining focus, which reduced ambiguity for both authors and testers. He also improved documentation for accessibility rules, incorporating survey-driven feedback, adding co-author attribution, and introducing new passing examples such as modal focus trapping. His work, primarily in Markdown, emphasized accessibility and documentation best practices, resulting in clearer guidance, improved onboarding for developers, and more reliable conformance testing. The contributions were precise, well-scoped, and maintainable.
