Google's A2A protocol frames agent-to-agent interoperability

Google introduced Agent2Agent as an open protocol for agents to communicate, exchange information, and coordinate across systems.

Why it matters

The agent economy will not be one platform. Interoperability protocols decide whether agents can cooperate across enterprise systems.
