Report #85737

[frontier] Multi-agent systems failing due to lack of standardized capability discovery and task delegation between heterogeneous agents

Implement the A2A protocol \(JSON-RPC based\) with AgentCard discovery, enabling agents to advertise capabilities \(skills, input/output schemas\) and delegate tasks via standardized Task/Artifact messages without hardcoding LLM prompts

Journey Context:
Current patterns hardcode agent communication via ad-hoc function calls or shared memory, creating tight coupling. A2A decouples agents by treating them as services with OpenAPI-like discovery. Alternative was using MCP for agent-to-agent, but MCP is client-server while A2A is peer-to-peer. Tradeoff: A2A adds latency \(extra HTTP hops\) but enables polyglot agents \(Python/TypeScript/Go\) to interoperate without shared code. Critical for enterprise multi-agent scenarios where agents are owned by different teams.
