Contributed to the google-gemini/gemini-cli repository by enhancing file exclusion logic to improve asset workflow reliability. Developed and implemented a feature in TypeScript that introduces default exclusion rules for .pak and .rpa game archive formats, ensuring these archives are not processed or included in binary-file operations. This update addressed edge-case failures in asset handling by strengthening the core file-handling logic, resulting in more predictable builds and analyses across projects. Collaborated with other contributors through code reviews and integration, applying full stack development skills to deliver a robust solution that streamlines game asset processing and reduces unintended archive-related issues.
