Agent skills
Skills for Claude Code, Codex, Cursor and other agents from the skills.sh directory: installs, security audit status and the command to add a skill.
A skill is not tied to one agent: npx skills add installs it into any supported one. Without -a the CLI finds the agents on your computer and asks where to add it.

Descriptions are the authors' own, in English. Read a skill's code in its repository before you install it.
What agent skills are
A skill is a folder with a SKILL.md file — instructions written for an AI agent — and sometimes scripts or templates. When a task matches the skill's description, an agent such as Claude Code, Codex or Cursor loads it and follows it: how to fill in a form, how to review code in a particular style, how to work with a certain file format. This page is a directory of such skills, based on skills.sh.
What the directory shows
- the top 10,000 skills by number of installs, synced daily;
- for each skill: name, author and repository, installs, the status of its security audit and the command that adds it, with a copy button;
- "Trending": the skills that gained the most installs over the last 7 days;
- filters by topic and by agent, and a search; each view shows up to 100 skills.
Reading the audit status
skills.sh publishes security audits of skills. We show the result as Passed, Warnings, Failed or Not audited. A passed audit lowers the risk but is not a guarantee: a skill can contain scripts that your agent will run on your machine. Read the code in the repository before you install a skill, especially one with few installs or no audit.
Installing a skill
- Find a skill through the topics, the agent filter or the search.
- Open its repository and look at SKILL.md and any scripts.
- Copy the command from the row and run it in your project.
- Ask your agent to perform a task that matches the skill.
About the descriptions
The short descriptions are the authors' own, in English, as written in each SKILL.md. We do not translate or rewrite them, and install counts are those reported by skills.sh.
