Jul 1, 2025July 2025 — OpenCSGs/csghub-server: Focused on strengthening the Prompt API reliability through an error-handling refactor. Delivered Prompt API Robust Error Handling and Standardized Errors, centralizing error management and standardizing responses across all prompt-related operations. Replaced generic HTTP status usage with explicit error types to improve consistency, debuggability, and the developer experience for downstream integrations. No major bugs fixed this month; the priority was architectural robustness and maintainability. Impact includes reduced incident surface area, faster issue diagnosis, and better support for i18n error handling in prompts. Technologies demonstrated include API design, centralized error handling, refactoring, and maintainability practices.
