Report #46651

[frontier] Multi-agent systems built on different frameworks cannot interoperate without custom integration code

Adopt the Agent-to-Agent \(A2A\) protocol to standardize capability discovery \(Agent Cards\), task delegation, and artifact exchange across heterogeneous agents from different vendors

Journey Context:
Previous approaches required homogenous stacks \(e.g., all LangChain or all CrewAI\) or brittle HTTP wrappers. The A2A protocol \(Google-led open standard\) treats agents as JSON-RPC endpoints that advertise capabilities via 'Agent Cards' \(JSON-LD metadata\). Tasks are stateful objects with artifacts \(typed MIME attachments\), enabling a LangGraph agent to delegate a sub-task to a remote CrewAI agent and receive structured results. This decouples agent construction from orchestration, enabling 'best-of-breed' agent swarms without vendor lock-in.
