Agent skills for Claude Code, Codex and Cursor
5 skill packs, each one read and checked by hand. See what a pack does, what it runs on your machine and how to install it. Stats updated 2 October 2026.
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.
Skills use one open format, so the same pack usually works in Claude Code, Codex, Cursor, Gemini CLI and other agents. A skill can include scripts that run on your machine, which is why every page here lists what a pack runs.

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.
