Agent-to-Agent

Google’s Agent-to-Agent (A2A) protocol is fast becoming the standard handshake for cross-agent communication in production agentic systems. A new deep-dive from freeCodeCamp — paired with a working GitHub implementation at win4r/openclaw-a2a-gateway — shows exactly how to wire A2A into an OpenClaw plugin so your agent can receive tasks from any A2A-compliant caller. This how-to summarizes the architecture and key implementation steps. For the full guide, see the freeCodeCamp article. What You’re Building An A2A plugin bridge does three things: ...

It’s the first time a Tier-1 carrier equipment vendor has put its weight behind a standardized inter-agent communication protocol. Important caveat up front: this is a press announcement from Huawei at an industry conference. The open-source repository details are sparse, and multiple reports frame this as “to be released during MWC” rather than live-now. Verify availability before building on it. ...
