Worked on enhancing the stability and reliability of the coze-dev/coze-loop repository by addressing a critical issue with the OpenAI integration. Focused on backend development using Go, the work involved fixing Azure API 404 errors through precise adjustments to the OpenAI protocol configuration and updating the relevant JSON field names. Enabled JSON schema response format capabilities for OpenAI, which laid the groundwork for future schema-based validation. Strengthened error handling and expanded test coverage to prevent regressions, ensuring robust API integration. The efforts concentrated on maintaining system reliability and preparing the codebase for more advanced validation features in subsequent development cycles.
