Part 4 of a series on technologies making AI agents more independent: the Agent2Agent (A2A) open protocol, hosted under the Linux Foundation with 26.5k GitHub stars. A2A lets agents discover each other via capability descriptions, delegate tasks to specialized agents, exchange messages and task results, and coordinate workflows across frameworks — so an agent can request help instead of handling everything itself.
