Worked on the infiniflow/ragflow repository to upgrade API documentation following a migration from Flask to Quart. Focused on implementing OpenAPI support using QuartSchema, replacing the previous Swagger-based documentation to align with modern standards and improve API discoverability. Addressed documentation gaps by introducing standardized OpenAPI interfaces, which enhanced integration reliability and made onboarding easier for external developers. Collaborated closely with another team member to ensure smooth feature integration and resolve compatibility issues, referencing repository issue #5264. The work centered on Python-based API development and documentation, leveraging skills in Flask, Quart, and OpenAPI to deliver a more robust developer experience.
