Worked on the infiniflow/ragflow repository, focusing on stabilizing the Python SDK by addressing a critical bug affecting non-streaming session calls. The main contribution involved modifying the session.ask method to return a single message when stream was set to False, ensuring the response format matched the documented API behavior. This change eliminated inconsistencies that previously caused confusion for downstream integrations and improved overall developer usability. The work required strong skills in Python and SDK development, with careful attention to API alignment and integration reliability. No new features were introduced during this period, as efforts centered on enhancing stability and consistency.
