Report #88993

[frontier] How do agents from different vendors/frameworks negotiate task delegation without tight coupling?

Adopt the Google A2A protocol: expose an 'Agent Card' \(JSON metadata at /.well-known/agent.json\) describing capabilities, and communicate via HTTP\+JSON-RPC with Task/Artifact/Message primitives for stateful, peer-to-peer negotiation.

Journey Context:
Previously, agents used ad-hoc REST APIs or MCP \(which is host-client, not peer-to-peer\). A2A decouples capabilities from implementation, allowing a LangGraph agent to delegate to a CrewAI agent seamlessly. Unlike MCP, A2A handles the full task lifecycle \(submitted, working, input-required, completed\) with streaming updates. This is the emerging standard for 2025 multi-agent topologies because it treats agents as autonomous services with persistent state, not just tools.
