Worked on the googleapis/python-genai repository to deliver version 0.2.2 of the GenAI Python SDK, focusing on improving reliability and the developer experience. Enhanced the SDK’s documentation for function calling and streaming, making integration and onboarding more accessible. Refined API error handling logic to increase robustness and proactively address edge cases, while expanding test coverage to ensure higher reliability. Updated the README and usage guides to provide clearer guidance for developers. The work involved Python and Jinja, with an emphasis on API integration, SDK development, and comprehensive testing. All changes were integrated through a Copybara-import commit to maintain workflow consistency.
