During September 2025, Lingyu Kong expanded the math_tools module in the jd-opensource/OxyGent repository by developing two new utilities: list_operation, which enables element-wise binary operations on lists, and calculate_expression, which safely evaluates mathematical expressions from strings. The work focused on enhancing computational flexibility while maintaining security and reliability. Lingyu applied Python and Pytest to implement and rigorously test these features, emphasizing robust unit testing to minimize regression risk. The approach demonstrated a commitment to maintainable, test-driven development and improved the FunctionHub architecture’s readiness for continuous integration, supporting safer and broader reuse of user-facing computation tools within the project.
