Worked on backend enhancements for the AstrBotDevs/AstrBot repository, focusing on improving API integration and cross-version reliability. Addressed issues with NVIDIA MiniMax M3 by setting a default max_tokens value and refactoring request logic to support both payload and extra_body parameters, ensuring flexible and robust API requests. Tackled Python 3.14 compatibility by implementing a fallback file search using direct subprocess calls to ripgrep, bypassing library crashes and maintaining search functionality. Emphasized thorough testing with pytest to validate both new and legacy behaviors. These updates enhanced backend stability, reduced support overhead, and ensured consistent operation across diverse Python environments and versions.
