Never heard of "agent skills" before? You're in the right place. This is a community-curated list of simple text files that teach AI assistants (like Claude, Copilot, or Codex) how to do new things on demand, without retraining. Unlike bulk-generated skill repositories, this collection focuses on real-world Agent Skills created and used by actual engineering teams. Compatible with Claude Code, Codex, Antigravity, Gemini CLI, Cursor, GitHub Copilot, Windsurf, and more.

Quick Start (30 seconds)

Step 1: Pick a skill from the directory below (or browse at agent-skill.co)

Step 2: Load it into your AI agent:

  • Claude Code: /skills add <github-url>
  • Claude.ai: paste the raw SKILL.md URL in a new conversation
  • Codex / Copilot: follow platform docs linked in Using Skills

Step 3: Ask your AI to use it. Just describe what you want in plain English.

That's it. No installation. No configuration. No coding required.

What Are Agent Skills?

Think of Agent Skills as "how-to guides" for AI assistants. Instead of the AI needing to know everything upfront, skills let it learn new abilities on the fly, like giving someone a recipe card instead of making them memorize an entire cookbook.

Skills are simple text files (called SKILL.md) that teach an AI how to do specific tasks. When you ask the AI to do something, it finds the right skill, reads the instructions, and gets to work.

How It Works

Skills load in three stages:

  1. Browse: The AI sees a list of available skills (just names and short descriptions)
  2. Load: When a skill is needed, the AI reads the full instructions
  3. Use: The AI follows the instructions and accesses any helper files

Why This Matters

  • Faster and lighter: The AI only loads what it needs, when it needs it
  • Works everywhere: Create a skill once, use it with any compatible AI tool
  • Easy to share: Skills are just files you can copy, download, or share on GitHub

Skills are instructions, not code. The AI reads them like a human would read a guide, then follows the steps.

How to Find Skills (Recommended)

SkillsMP Marketplace

SkillsMP Marketplace

It is recommended to use the SkillsMP Marketplace, which automatically indexes all Skill projects on GitHub and organizes them by category, update time, star count, and other tags — making it the easiest way to discover and evaluate skills.
