Worked on the google/adk-js repository to enhance Gemini API compatibility by developing a feature that wraps array responses in function tools, ensuring consistent handling of array data types. Addressed a core reliability issue by updating the response path to align with Gemini API requirements, which improved the robustness of array processing. Automated tests were implemented using TypeScript to validate the new response format and maintain reliability across updates. Collaborated closely with another contributor to review and refine the changes, demonstrating a focus on teamwork and code quality. The work emphasized API development, automated testing, and strong TypeScript proficiency throughout the process.
