Developed and delivered policy-driven task routing protection for the google/adk-python repository, focusing on Task Transfer Validation for Peer Agents. This feature prevents task transfers to sibling agents when disallow_transfer_to_peers is enabled, strengthening governance and security in multi-agent deployments. The implementation involved adding a validation guard within the _get_agent_to_run function, robust error handling, and comprehensive unit testing to ensure reliability. Manual end-to-end verification was also performed using adk web. The work demonstrated proficiency in Python, async programming, and backend development, while contributing to improved code quality and closing a key issue through collaborative development and thorough testing strategies.
