Report #88553

[frontier] Agents from different frameworks cannot interoperate without custom REST integrations for each pair

Implement the Agent-to-Agent \(A2A\) protocol using JSON-RPC 2.0 with Agent Cards for capability discovery, Task objects for state management, and Artifacts for data exchange

Journey Context:
Previous approaches required bespoke APIs or message queues for every agent pair, creating N×N integration complexity. A2A standardizes peer-to-peer agent communication by treating agents as autonomous entities that expose capabilities via Agent Cards \(JSON metadata endpoints\), communicate via JSON-RPC over HTTP, and manage long-running tasks through a standard Task lifecycle \(submitted -> working -> input-required -> completed/failed\). This eliminates vendor lock-in and enables cross-organizational workflows where agents from Google Cloud, Anthropic, and OpenAI ecosystems can delegate tasks to each other without prior integration agreements.
