What is an agent skill?

An agent skill is a folder with a SKILL.md file that teaches an AI coding agent how to do one job, such as reviewing code or designing an interface. The agent reads only the skill's name and description until a task needs it, then loads the full instructions.

Questions about agent skills

Do Claude skills work in Codex and Cursor?

Usually, yes. Most packs follow the open Agent Skills format, which Claude Code, Codex, Cursor, Gemini CLI and other agents read. Install steps differ by agent, so each page lists the agents the maker names and the command for each.

How is a skill different from an MCP server?

An MCP server connects the agent to a tool or data source. A skill tells the agent how to do a task: which steps to take and in what order. Many setups use both.

Is it safe to install a skill?

Read it first. A skill can ship scripts, hooks and shell commands that run on your machine. Each page here lists what a pack runs, taken from the files in its repo.

Made a skill?

Paste your GitHub repo link. Listing is free and we review within 7 days.
