What is Agent Skills Hub?
AgentSkillsHub is an open-source directory of 178,000+ AI agent tools, MCP servers, Claude skills, and Codex skills built for developers and teams evaluating open-source AI tooling. Every repository receives a 0–100 quality score and a security grade (SAFE, CAUTION, UNSAFE, or UNAUDITED) based on a rule-based scan covering 11 red-flag categories. The catalog refreshes every 8 hours, and users can browse by category, search by keyword, or explore curated scenario pages. The project is maintained independently by Jason Zhu with transparent methodology.
