Report #66230

[frontier] How do I make multiple AI agents discover and communicate with each other without hardcoded orchestration?

Implement the Agent2Agent \(A2A\) protocol using JSON-RPC over HTTP with Agent Cards for capability discovery, enabling dynamic peer-to-peer task delegation rather than static DAGs.

Journey Context:
Static orchestration graphs \(CrewAI, AutoGen\) require redeployment to add agents and break under dynamic scaling. The A2A pattern treats agents as services that publish Agent Cards \(JSON metadata\) to a directory, allowing runtime discovery and capability negotiation. This mirrors the shift from monoliths to microservices. Tradeoff: higher latency than direct function calls and requires idempotency handling for retries.
