Build Cross-Language Multi-Agent Team with Google’s Agent Development Kit and A2A

In the context of a contract compliance pipeline, a Python agent and a Go agent collaborate effectively using the Agent2Agent (A2A) protocol, allowing them to function together without rewriting their respective codebases. The Python agent extracts terms from legal contracts using Gemini, while the Go agent validates these terms against corporate policies. The integration is facilitated by Google’s Agent Development Kit (ADK), which simplifies the orchestration of multi-agent systems through cross-language collaboration. This setup addresses common issues of monolithic AI systems, such as context degradation, unhandled exceptions, and testing challenges, by decomposing them into specialized microservices. The A2A protocol serves as a universal communication standard, similar to HTTP, enabling agents to interact regardless of their internal implementations. This approach not only maintains the technological independence of different teams but also enhances resilience and auditing capabilities, with the entire system being available as an open-source application for deployment and testing.
