AI Agent Skills is a curated, open-source directory of reusable capabilities — called skills — that extend AI agents like Claude Code, Codex, and Cursor with specialized workflows for tasks such as writing, research, development, and automation.
What is AI Agent Skills?
AI Agent Skills is a community-driven marketplace hosting over 550 curated skills for AI agents. It aggregates one-line-installable tools from GitHub repositories, each packaged as instructions, templates, scripts, and workflow guidance. The platform is maintained by the open-source community and is not affiliated with Anthropic or OpenAI. Skills are compatible with Claude Code, OpenAI Codex, Cursor, GitHub Copilot, and other agent ecosystems.
Key Features
- Extensive catalog — Over 550 skills across 13 categories, including Agent Workflows (53 skills), Research & Knowledge (64), Frontend (33), Backend & API (52), and more.
- One-line installation — Each skill comes with a copyable command that automatically fetches and verifies the skill in your AI environment (e.g., Claude Desktop).
- Open-source and community-verified — All skills are hosted on public GitHub repositories; the community reviews popular skills for safety.
- Editors' Choice and trending sections — Curated picks (e.g.,
subagent-driven-development,summarize) and weekly trending lists highlight top-performing skills with install counts (e.g., 233K+ installs for some). - Search and filter — Browse by category, popularity, or recent updates; search by keywords (e.g., "MCP", "Writing").
- Free to use — Browsing and discovering skills is free; most skills are open-source and free to install.
Who is it for?
- AI developers and builders – Equip Claude Code or Codex with domain-specific skills for coding, testing, or deployment.
- Automation engineers – Use skills like
dispatching-parallel-agentsorexecuting-plansto orchestrate multi-step workflows. - Content creators and marketers – Leverage writing, SEO, and research skills (e.g.,
summarize) to generate or analyze content. - Indie hackers and students – Quickly add capabilities like Python tutoring or image generation without building from scratch.

How does it work?
Installation is a three-step process: 1) Browse the catalog and select a skill. 2) Copy its one-line installation command from the skill detail page. 3) Paste the command into your AI agent's chat or terminal (e.g., Claude Desktop) — the system fetches and verifies the skill automatically.
FAQ
Is AI Agent Skills free?
Yes, browsing and discovering skills on AI Agent Skills is completely free. Most listed skills are open-source and free to install. Some skills may have optional paid tiers set by their authors, but the directory itself costs nothing.
Are these skills safe to use?
Most skills are open-source, allowing you to review the code. The platform verifies popular skills, but always recommend reviewing requested permissions (like file access or internet) before installation.
How do I submit my own skill?
Click the "Submit Skill" button on the site. You'll need a public GitHub repository with a clear README. The team reviews submissions for quality and safety before listing.
Can I use multiple skills together?
Yes, skills are designed to work independently. You can combine, for example, a research skill with a writing skill in the same workflow without conflicts.
How does AI Agent Skills differ from MCP?
MCP (Model Context Protocol) is the underlying standard. Skills are the actual reusable tools built on that standard — think of skills as apps and MCP as the operating system. (GitHub)
