How to choose the best agent skill
Start with the job you want done better, such as code review, SEO, documents or testing. Compare skills here by stars and recent activity, then open the listing to read the SKILL.md and every script. Prefer short, specific skills with a clear description, because the description decides when your agent loads it.
Check what it can touch
A skill that only holds instructions is lower risk than one that runs shell commands, reads environment variables or connects to the internet. The label on each listing shows what our checks found.
Check the owner
Several projects share names like "Agent Skills" or "Skills". The owner name on each listing tells them apart, so you can see who maintains the code before you install it.
Check activity
Skills pushed in the last 12 months show by default. Switch to All to include older projects.
How to install an agent skill in Claude Code, Codex, Gemini CLI or Copilot
An agent skill installs by copying its folder, the one that holds SKILL.md, into your agent's skills folder. Restart the agent and check it lists the skill. In Claude Code you can also add a plugin marketplace that bundles skills. Every listing shows the source repository.
| Agent | Personal skills | Project skills |
|---|---|---|
| Claude Code | ~/.claude/skills | .claude/skills |
| OpenAI Codex | ~/.agents/skills | .agents/skills |
| Gemini CLI | ~/.gemini/skills or ~/.agents/skills | .gemini/skills or .agents/skills |
| GitHub Copilot in VS Code | ~/.copilot/skills | .github/skills or .agents/skills |
/plugin marketplace add anthropics/skillsWhat "what it can touch" means
Each listing shows what our automated checks found the skill's code can do, in plain words: run shell commands, run dynamic code, read or write files, read environment variables and secrets, control a browser, connect to databases, send messages, touch money, or connect to the internet. The checks can miss things, so read the code too.

How this list is ranked
Skills pushed in the last 12 months are shown by default, ordered by GitHub stars. Switch to All for older projects, or sort by newest or recently updated. Stars come from public GitHub data and are refreshed on a schedule, so a count can lag GitHub by a few days. Scan results are provided under our scan policy.
Agent Skills FAQ
What are agent skills?
Agent skills are folders of instructions, scripts and reference files built around a SKILL.md file. The agent reads each skill's name and description at startup and loads the rest only when a task matches, so many skills can sit installed without filling the context window.
What is the difference between Claude skills and agent skills?
They are the same format. Anthropic introduced Skills for Claude, and the SKILL.md format is now an open specification that Codex, Gemini CLI, GitHub Copilot and other agents also read, so one skill folder can work across them.
How do I install Claude skills in Claude Code?
Copy the skill folder into ~/.claude/skills for all projects or .claude/skills for one project, then restart Claude Code. You can also add a plugin marketplace with /plugin marketplace add owner/repo and install a bundled skill from it.
Are agent skills safe?
A skill can include scripts that run with your agent's permissions, so treat it like code you did not write. Read SKILL.md and every script, look for network calls and hidden instructions, and check what the listing says it can touch and when it was last scanned.
What is the difference between skills and MCP servers?
An MCP server gives an agent access to an outside system, such as a database or an API. A skill teaches the agent how to do a task, and it can tell the agent how to use an MCP server's tools, so many setups use both.
Where can I find the best Claude Code skills?
This directory ranks open-source skills by GitHub stars and recent activity, with a what-it-can-touch label and dated scan reports where run. Filter by category, such as coding, design or research, then read the SKILL.md before you install.
Can I list my own skill?
Yes. Listing is free and so is the automated scan. Submit the GitHub repository, or claim an existing listing to edit it. Paid selling opens soon.
