added conditionalcgent for runtime workflow branching. #4400
Conversation
Summary of ChangesHello @jayy-77, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces the IfAgent (Conditional Agent) into the ADK framework, significantly enhancing the ability to create dynamic and adaptive agent workflows. By allowing the execution path to be determined at runtime based on a user-defined condition, this feature enables more sophisticated decision-making and flexible orchestration of agents. The IfAgent seamlessly integrates with the existing configuration system, supporting both asynchronous and live execution, and provides robust state management for resumable operations. Highlights

Code Review
This pull request introduces the IfAgent, a conditional branching agent that allows for runtime workflow decisions based on a condition function. It also includes the necessary configuration classes and integrations into the existing agent framework. The implementation is generally well-structured and documented. I've identified a couple of areas for improvement related to exception handling and minor code redundancy.

Catching a broad Exception can mask specific issues and make debugging more difficult. Consider catching more specific exceptions that you expect to handle, or re-raising the exception after logging if it's an unexpected error. While defaulting to False is a fallback, understanding the root cause of failures is important.

The chosen_agent is already determined and assigned on lines 206-208. This re-assignment is redundant and can be removed for cleaner code.

Similar to _run_async_impl, the chosen_agent is already determined on lines 248-250. This re-assignment is redundant and can be removed.
