Worked on stabilizing the bundle download workflow in the crc-org/crc repository by addressing a bug related to tag validation for the command line interface. Focused on enforcing explicit tag requirements when using the -b flag, the solution improved input validation and error handling to prevent ambiguous bundle downloads. Implemented robust error messaging to guide users and reduce downstream support issues. Developed comprehensive unit tests in Go to reproduce and verify the fix, ensuring predictable behavior and reliability. The work emphasized careful error handling and thorough testing, contributing to a more stable and maintainable bundle download process within the project.
