Report #87928
[frontier] How do agents discover and delegate tasks to other agents without tight coupling or hardcoded integrations?
Implement the Google Agent2Agent \(A2A\) protocol: expose Agent Cards \(JSON metadata\) for capability advertisement, use the Tasks API \(JSON-RPC\) for structured delegation with asynchronous state updates, and support streaming for real-time collaboration.
Journey Context:
Current multi-agent systems require custom integration per pair \(e.g., LangChain to CrewAI\). A2A \(April 2025\) standardizes agent interoperability at the protocol layer—similar to HTTP for web servers. Key insight: Agents advertise capabilities via Agent Cards \(skills, auth requirements\), then negotiate task delegation via a Task object that tracks state \(submitted, working, input-required, completed\). Critical for enterprise environments with agents from multiple vendors. Tradeoff: protocol overhead vs. tight integration, requires adopting JSON-RPC style messaging instead of direct function calls.
