AIAgentSkills

AIAgentSkills is a free, community-run index of “AI Agent Skills” — reusable capability packages (also known as Claude skills or AI skills) that you can install to teach an agent like Claude or Codex a specific workflow, from code review checklists to design polish to research tasks. Rather than building or hunting for these yourself, the directory lets you search, browse by category, and copy a one-line install command for each skill.

The directory currently lists 4,600+ skills sourced from 600+ open-source GitHub maintainers, with new releases tracked and added regularly. It’s explicitly independent — community-run and not affiliated with Anthropic or OpenAI, despite indexing skills built for their agent ecosystems.

Key Features

• Searchable index of 4,600+ AI agent skills
• Browse by category: Agent Workflows, Prompting & Reasoning, Research & Knowledge, Browser & Web, Writing & Content, Design & UI, Marketing & SEO, Productivity, plus developer-focused categories (Code Generation, Frontend, Backend & API, Database, Testing & QA, DevOps & Cloud, Security, MCP & Integrations)
• Editor’s Choice, New Arrivals, and Trending sections to surface notable skills
• One-click install command copy for each skill
• Source-linked listings pointing back to each skill’s original GitHub repository
• Skill vs. MCP server vs. slash command comparisons to help you pick the right approach
• Directory statistics (skills, authors, stars, views) updated automatically

What’s the Difference Between a Skill, an MCP Server, and a Slash Command?

This directory is genuinely useful for understanding the distinction, not just browsing:

• AI Agent Skill — a reusable capability package (instructions, scripts, and resources) you install so an agent learns a workflow, portable across compatible tools like Claude or Codex
• MCP server — a protocol endpoint that exposes live tools or data to an agent (APIs, browsers, databases), used when you need real-time external connections rather than a packaged workflow
• Slash command — a quick, often local shortcut inside an agent’s CLI or UI for fast, portable actions, without the depth of a full skill package

---

Who Should Use This Directory?

• Developers using Claude Code, Codex, or similar agent tools who want ready-made skills instead of writing every workflow from scratch
• Teams standardizing how their AI agents handle recurring tasks (code review, documentation, deployment checklists)
• Anyone curious what “AI Agent Skills” actually are and how they differ from MCP servers or slash commands
• Open-source contributors wanting to publish and share their own agent skills

Pros and Cons

Pros

• Genuinely free, with no paywall or account required to browse and copy install commands
• Every listing links back to its original source repository, so you can inspect the code before installing
• Well-organized by both use-case category and developer-specific category
• Editorial curation (Editor’s Choice, Trending) helps surface quality skills in a large catalog
• Transparent about being an independent, community-run project rather than an official Anthropic/OpenAI product

Cons

• Skills are third-party, community-submitted code — review a skill’s source before installing, especially newer or lower-starred ones, the same way you’d vet any third-party package
• Quality and maintenance vary by individual skill author, since this is an index rather than a single maintained product
• Best suited to developers and technical users already working with agent tools like Claude Code or Codex, less relevant if you don’t use those platforms

FAQ

What is an AI Agent Skill?

An AI Agent Skill (also called a Claude skill or AI skill) is a reusable capability package that teaches an agent a workflow, such as code review, writing, or research — installed similarly to a plugin for AI agents like Claude or Codex.

What’s the difference between Skills and MCP?

A Skill is a packaged, reusable workflow capability, while MCP (Model Context Protocol) is a protocol for connecting an agent to live external tools and data, like APIs or databases. Skills teach a workflow; MCP provides a live connection.

Are these skills safe to use?

Every listing links back to its original open-source repository, so you can review the code before installing. As with any third-party package, it’s worth checking a skill’s source, maintainer, and popularity before running it, especially for newer or less-established listings.

Is this service free? Yes. The directory is free to browse, search, and use, with no account or payment required.

Is this website affiliated with Anthropic or OpenAI?

No. The directory describes itself as independent and community-run, despite indexing skills built for agent ecosystems like Claude and Codex.

How are skills added to the directory?

Skills are sourced from published, open-source GitHub repositories rather than manually submitted; releases are gated through automated quality checks before being marked reviewed.

Can I use multiple skills together?

Generally yes, since skills are designed to be modular, reusable capabilities — but compatibility can depend on the specific agent tool and skills involved, so check each skill’s documentation for specifics.
