Worked on stabilizing the OpenDriveLab/AgiBot-World codebase by addressing a persistent correctness issue in Python. Focused on code refactoring and typo correction, the developer identified and resolved a recurring class name typo, ensuring that ActionExpertDecoderLayer was consistently referenced across all relevant files. This targeted bug fix eliminated potential runtime errors caused by misreferenced components and improved overall maintainability. No new features were introduced during this period, as the primary goal was to enhance code reliability. The work demonstrated attention to detail in code quality, leveraging Python and best practices in refactoring to reduce risk and support long-term project stability.
