9 Unified Abstractions and Protocols for Agent Collaboration

Standards are what turn a collection of agents into an ecosystem.

A team standardizes on AG2, then finds that the retrieval service it most needs is a LangGraph deployment owned by another group and reachable only over HTTP. Goal decomposition, routing, retries, and aggregation all survive that discovery. The assumption underneath every orchestrator in Chapter 8 does not: an agent there is a Python function inside one process and one runtime, and here the function call becomes a protocol boundary. Agents built on different frameworks and in different languages must still discover each other, delegate tasks, and exchange results without forcing their owners to rewrite interfaces. That ...
