Worked on the google/adk-python repository to resolve a deadlock issue affecting Gemini 3.1 Flash Live models, focusing on improving live-mode responsiveness and reliability. Addressed the problem by enabling immediate yielding of tool_call_parts upon message receipt, which allowed tool calls to execute without waiting for the turn_complete signal. This approach improved latency and first-message execution while maintaining backward compatibility with earlier models. The solution was validated through live mode testing to ensure no regressions in existing flows. The work involved asynchronous programming, backend development, and unit testing, leveraging Python to enhance user experience and support performance objectives.
