Developed enhanced OAuth flow configurability for the Shubhamsaboo/adk-python repository, focusing on backend development and API integration using Python. The work introduced support for configurable audience and prompt parameters within OAuth2Auth and AuthHandler, enabling seamless integration with OAuth providers that require specific audience values or custom prompt behaviors. Comprehensive automated tests were added to validate the new options and prevent regressions, improving both security and maintainability. By delivering these features in a focused scope, the update streamlined client authentication workflows and provided clearer debugging through expanded test coverage, addressing integration challenges without introducing new bugs during the development period.
