Report #65763

[frontier] Multi-agent systems rely on hardcoded orchestration or ad-hoc HTTP calls, preventing dynamic capability discovery and delegation

Adopt the A2A \(Agent2Agent\) protocol with Agent Cards for capability advertisement and structured Task/Artifact/Update message flows

Journey Context:
Point-to-point integrations \(Manager→Worker\) don't scale across teams. A2A introduces a standard where agents publish Agent Cards \(JSON-LD\) at well-known URLs describing their skills and auth requirements. When an agent needs help, it sends a Task to the remote agent's URL, which responds with streaming Updates and final Artifacts. This allows dynamic federation without hardcoded orchestration, enabling agents to discover and hire each other at runtime.
