Worked on stabilizing the interactive console UI for the bytedance/deer-flow repository, focusing on improving input handling to prevent application crashes when users entered empty input. Addressed this issue by implementing a loop that prompts users until a non-empty string is provided, thereby enhancing the reliability and user experience of the command line interface. The solution was developed using Python and leveraged command line interface skills to ensure robust error handling in live sessions. This targeted bug fix reduced edge-case failures and runtime errors, with clear traceability maintained through detailed commit messages linked to the relevant issue in the repository.
