Worked on the FluidVoice repository to address a bug affecting LLM request integrity by ensuring the streaming flag was consistently included in both streaming and non-streaming paths. This involved updating the buildChatCompletionsBody and buildResponsesBody functions in Swift, with comprehensive unit tests added to verify correct behavior and improve test coverage. Additionally, applied swiftformat to LLMClient.swift to align documentation comments with code standards, enhancing code readability and maintainability without altering functionality. The work focused on backend development and API integration, reducing provider compatibility risks and supporting long-term reliability through explicit, well-documented commits and targeted code quality improvements.
