Che Kun worked on the langgenius/dify repository, focusing on improving UI localization stability for the project’s front end. During this period, Che identified and resolved a critical localization bug affecting the dynamic display of tool counts, ensuring that the correct action term appeared across different languages. The solution involved refining the i18n logic within the React-based TypeScript codebase, which improved consistency for users in various locales. Although no new features were released, Che’s work addressed a nuanced issue in internationalization, demonstrating attention to detail in front end development and contributing to a more reliable and user-friendly multilingual interface.
