Announcing the Agentic Resource Discovery specification- Google Developers Blog

This post introduces the Agentic Resource Discovery (ARD) specification, an open standard for agents to find and verify capabilities (tools, skills, other agents) across the web. It details the architecture using catalogs (published under an organization's domain for trust) and registries (search engines for the agentic web). The post explains the four key phases of ARD: publishing catalogs, discovery/resolution, cryptographic verification, and direct runtime connection. It also announces Gemini Enterprise Agent Platform's Agent Registry as an enterprise-grade implementation supporting ARD, including governance features like URNs, egress policies, and Agent Identity for trust manifests.
