Report #70564

[frontier] Multi-agent systems from different vendors cannot discover capabilities or negotiate tasks without custom glue code

Implement Google's Agent2Agent \(A2A\) protocol for capability discovery and task delegation: expose agent manifest at /.well-known/agent.json, use push notifications for async updates, and standardize on JSON-RPC for method invocation

Journey Context:
MCP connects agents to tools; A2A connects agents to agents. Without a standard, every agent integration requires bespoke adapters. A2A provides the HTTP-based discovery and streaming mechanisms that allow a LangChain agent to delegate to a CrewAI agent seamlessly. This replaces brittle 'wrapper agents' with protocol-native interoperability.
