Worked on the OpenSPG/KAG repository to address a critical issue in LLM client communication and entity processing. Focused on standardizing entity input across std.py and ollama_client.py, the developer ensured that max_tokens was consistently passed in all prompt flows, which improved the reliability of builder and client interactions. Enhanced error handling was implemented to better manage incomplete JSON responses from LLM clients, reducing downtime and troubleshooting for other developers. The work was carried out using Python and involved skills in API client integration, bug fixing, and LLM integration, resulting in a more stable and maintainable codebase for future development.
