LibreFang Registry

Community-maintained content registry for LibreFang — the open-source Agent Operating System.

This repository is the single source of truth for all installable content definitions. Anyone can submit a PR to add new agents, hands, MCP servers, skills, or provider models — no changes to the LibreFang binary required.
