Developed an enhanced ReAct agent capability for the yichuan-w/LEANN repository, focusing on integrating web and local knowledge base search to enable real-time information retrieval. Leveraging Python and full stack development skills, the work centered on API integration and data fetching to improve the agent’s ability to deliver up-to-date, comprehensive answers. The feature was delivered through a focused code commit, establishing a scalable foundation for future expansion of knowledge sources and search capabilities. No major bugs were addressed during this period, as efforts were concentrated on building robust, extensible infrastructure to support more advanced search and retrieval functionalities going forward.
