Report #55931
[frontier] Agents from different vendors cannot discover capabilities or negotiate task delegation
Implement Google's A2A \(Agent-to-Agent\) protocol to expose agent capabilities as 'Agent Cards' and standardize task negotiation, status updates, and artifact exchange
Journey Context:
Current multi-agent systems require custom integration between each pair of agents. MCP standardizes tool-calling, but not agent-to-agent collaboration. Google's A2A protocol \(released 2025\) defines how agents advertise capabilities \(Agent Cards\), request tasks from other agents, and stream status updates/artifacts. This enables a 'network of agents' where specialized agents \(coding, research, math\) discover and delegate to each other without hardcoded integration. Unlike MCP \(client-server\), A2A is peer-to-peer. Critical for building ecosystems where third-party agents can be composed.
