Agent Skills is an open registry of reusable capabilities for AI coding agents. It provides over 19,000 installable skills that add new workflows, best practices, and domain knowledge to agents like Claude Code, Codex, GitHub Copilot, and Antigravity. Users browse by category or search, copy a one-line install command, and drop the skill into their agent's skills directory. The registry is free, open source, and rescanned daily.
What is Agent Skills?
Agent Skills is a community-driven directory of installable instruction sets for AI coding assistants. It takes a user's need for a specific agent capability (e.g., Flutter development, PDF conversion) and returns a one-command installable skill file (SKILL.md). The platform runs as a web registry at agentskills.codes and is maintained by the open source community with no single corporate owner.
Key Features
- Vast skill library — 19,296 installable skills across categories like Coding, Productivity, Design, and more, rescanned daily.
- One-command installation — Install any skill with a single
npx degitcommand, tailored to the user's agent and scope (project-local or global). - Multi-agent support — Skills work with Claude Code, Codex, GitHub Copilot, Antigravity, and other major AI coding assistants.
- Safety scanning — Every skill undergoes a static safety scan with visible grades (clean/review/warn) and capability flags before installation.
- Source transparency — Each skill links to its GitHub repository with stars, license, and last-commit date for vetting.
- Portable format — Skills are plain SKILL.md files that can be forked, edited, or vendored into any repository, with no vendor lock-in.
Who is it for?
- Software developers — Add specialized skills like Flutter development, Godot game engine knowledge, or SVG precision to their coding agent.
- Data scientists and researchers — Install skills for literature reviews, data analytics, or PDF-to-markdown conversion to accelerate research workflows.
- DevOps and infrastructure engineers — Use skills for Grafana dashboards, FastAPI templates, or effective Go practices to enforce best practices.
- Teams standardizing agent behavior — Fork and vendor skills to ensure all team members' agents have consistent coding guidelines and toolchains.
What can you do with Agent Skills?
- UI/UX designers — Use the
ui-ux-pro-maxskill to get 50 styles, 21 palettes, 50 font pairings, and 20 chart types for React, Next.js, Vue, Svelte, SwiftUI, and React Native. - Content creators — Convert entire PDF documents to structured Markdown with the
pdf-to-markdownskill, preserving full context for AI analysis. - Mobile app developers — Accelerate cross-platform development with the
flutter-developmentskill covering widgets, state management (Provider/BLoC), navigation, and API integration. - Project managers — Create professional draw.io diagrams with integrated PMP/PMBOK methodologies using the
drawio-diagrams-enhancedskill.
FAQ
What are agent skills?
Agent skills are reusable instruction sets that teach AI coding assistants new workflows, best practices, and domain knowledge. They are plain SKILL.md files that live in an agent's skills directory.
How do I install an agent skill?
Copy the one-line command from the skill page (e.g., npx degit owner/repo) and run it in your terminal. The skill is placed in the appropriate skills directory for your agent.
Which AI clients support agent skills?
Skills work with Claude Code, Codex, GitHub Copilot, Antigravity, and other AI coding assistants that support a skills directory.
Are agent skills free?
Yes, all skills in the registry are free to use. The registry itself is open source.
Why use a skill instead of just prompting the AI?
Skills provide consistent, vetted instructions without the need for prompt engineering. They can be shared, versioned, and audited, ensuring repeatable behavior across sessions and team members.
