Worked on stabilizing the Converse API surface within the instabase/aihub-openapi repository by reverting an unintended OpenAPI specification update. Using YAML for precise API specification management, the developer restored prior API behavior to maintain backward compatibility and minimize production risk for existing clients. The rollback was executed in a single, well-scoped commit, ensuring clear traceability and facilitating quick remediation if necessary. Deprecated parameters such as enable_entity_detection, write_converted_image, and write_thumbnail were removed to streamline the API surface and reduce future maintenance overhead. This work demonstrated careful change impact analysis and disciplined rollback practices in API specification management.
