Worked on enhancing the file search functionality in the softwaremill/sttp-ai repository by refactoring the FileSearchToolCall and its associated nested case classes within ThreadRunsResponseData.scala. Focused on aligning the data structures with the latest OpenAI API documentation, the developer updated the file search format to include ranking options and results, thereby improving the reliability and maintainability of API interactions. Leveraged Scala for data modeling and API integration, ensuring the codebase remains robust and adaptable for future updates. The work addressed the need for precise API alignment, supporting more consistent and predictable file search behavior within the project’s evolving architecture.
