Agent Skills Hub

About

What are agent skills?

Agent skills package instructions, scripts, and reference material into a single folder (SKILL.md) so an AI agent can perform a specific task better. Claude, ChatGPT/Codex, Cursor, Gemini CLI, and GitHub Copilot all support the same format.

About this site

We collect skills from across the web and show which agents they work with and how to install them. Each skill belongs to its original author, and we always link to the source.
