[frontier] Hardcoding agent endpoints creating brittle integration in enterprise agent ecosystems?

Implement the Agent2Agent \(A2A\) protocol to enable dynamic capability discovery, where agents advertise their skills via Agent Cards and communicate via standardized Task messages with artifact streaming.

Journey Context:
Current multi-agent architectures hardcode REST endpoints between services \(Agent A POSTs to Agent B at /api/v1/analyze\). This creates brittle dependency meshes that break when services migrate or versions change. The A2A protocol \(Google's open standard\) introduces 'Agent Cards' \(JSON metadata describing capabilities, auth schemes, and endpoints\) and a standardized Task lifecycle \(submitted -> working -> input-required -> completed\). Agents discover peers via capability registries rather than DNS, and stream results via 'Artifacts' \(typed data chunks\). This decouples implementation from interface—agents advertise semantic capabilities \('document-analysis-v2'\) rather than IP addresses. The alternative \(service meshes like Istio\) handle traffic but not semantic capability discovery or authentication negotiation. This pattern enables 'agent marketplaces' where AI workers are fungible and discovered at runtime via A2A.
