For two years the story of enterprise AI has been an agent calling a model, and — more recently — an agent calling a tool. There's a third call now, and most teams can't see it: an agent calling another agent. That hop has a name — agent-to-agent (A2A) — and it is the least-governed surface in the entire AI stack.

This post is a practical definition of A2A: what the protocol actually is, why the delegation hop between two agents is a blind spot your existing controls don't cover, and what it takes to govern it.

AI agents are moving from demos to production. Engineering teams are deploying autonomous systems built on LangChain, CrewAI, AutoGen, and custom agent frameworks that call external tools, query databases, send emails, and modify infrastructure — all without a human in the loop.
