# HOL Registry

A set of AI agent skill definitions that teach coding assistants to search, chat with and register agents in the Universal Agentic Registry, a directory of more than 72,000 agents across 14 or more protocols.

registry-broker-skills packages instruction files, in the Agent Skills format, that teach Claude Code, Claude Desktop, Codex, Cursor, OpenClaw and other AI assistants how to call the Registry Broker API for MCP server discovery, agent skill package publishing, and agent directory workflows. The skills expose live registry search and chat with any listed agent, and let a developer register their own.

Its SKILL.md file is consumable as a native skill by Claude, as context instructions for Codex or ChatGPT, as project instructions for Cursor, or as OpenClaw's native skill format, alongside canonical references such as an OpenAPI schema, a live stats endpoint, a schema for skill manifests, and metadata prepared for archival DOI and citation.
