Worked on the openclaw/openclaw repository to address a stability issue in the macOS user interface, focusing on bug fixing and reliability. The primary contribution involved resolving an infinite loop in the Cost Usage submenu by removing a self-delegation assignment, which previously caused recursive submenu insertion and potential application hangs. This targeted fix improved the maintainability and user experience of the macOS application by reducing the risk of UI freezes and related support issues. The work was implemented using Swift and demonstrated attention to detail in macOS development, emphasizing low-risk, maintainable solutions that enhance overall code quality and application stability.
