Google’s NEW Agent2Agent Protocol
AI Summary
Summary of Google Cloud Next 2025 Developer Keynote
Focus on Agents: The keynote heavily emphasized the term “agents,” indicating a shift in focus towards agent-centric technologies.
Expo Area Observations: In collaboration with YouTuber Prompt Engineering, the presenter explored demos, noting a lack of innovative agent use—most were basic workflows like currency converters rather than groundbreaking interactions.
Agent-to-Agent Protocol (A2A):
- Announced as a new way for agents to communicate with each other rather than just to tools.
- Allows for negotiations between agents about tasks, formats, and languages, enhancing collaboration.
- Built with standards like HTTP, SSE, and JSON RPC for security.
Discovery and App Store Concept: The vision includes agents discovering each other through an “agent store,” where agents could select other agents for tasks and potentially pay for services.
Development Kit: Google introduced an Agent Development Kit featuring sample agents for practical implementation, promoting multi-language collaboration.
Github and Resources: The best way to explore the new protocol is through the provided GitHub repo, which details conceptual overviews and agent specifications for developers.
Concerns About Adoption: Notably, Anthropic’s absence from the listed technology partners raises questions about the protocol’s future and potential for conflicting systems.
Feedback Invitation: Google has expressed interest in community feedback on this protocol and its applications, encouraging thoughts on improvements or inclusions.
