Worked on enhancing message compatibility verification in the Auterion/px4-ros2-interface-lib repository by improving how message definition files are discovered and validated. Developed a recursive file search mechanism in Python, enabling the check-message-compatibility.py script to locate message definition files within nested subfolders, which addressed challenges with versioned path structures. This approach reduced the risk of false compatibility results when validating ROS2 interfaces and improved the maintainability of the compatibility workflow. The work focused on file system operations and scripting, resulting in a more robust and future-proof process for managing message definitions in complex directory hierarchies within the repository.
