Developed A2A-compliant artifact streaming for artifact updates in the strands-agents/sdk-python repository, focusing on backend development and robust unit testing using Python. The implementation introduced a feature flag to manage rollout, ensuring backward compatibility and reducing deployment risk. Comprehensive test coverage was added to validate the new streaming path, while targeted refactoring of the StrandsA2AExecutor class improved maintainability and clarified initialization logic. The work addressed test flakiness and stabilized the artifact update flow, with careful state management and code cleanups. These enhancements improved artifact management reliability and prepared the codebase for broader adoption of the new streaming feature.
