Agentic Resource Discovery: Let agents search

This post introduces the Agentic Resource Discovery (ARD) specification, a draft open standard for how AI agents find and connect to capabilities across federated registries. Hugging Face's Discover Tool is presented as a reference implementation, integrating the Hub's semantic search to provide ARD catalog entries for Spaces, Agent Skills, and MCP Servers. The post details the `ai-catalog.json` manifest format and the `/search` registry API, and demonstrates usage via the `hf discover` CLI command and direct REST API calls. It emphasizes the importance of verification alongside discovery.
