The definitive resource for Agent Skills - modular capabilities revolutionizing AI agent architecture
Curated resources for building and using Agent Skills.
Agent Skills are modular, standardized SKILL.md packages that give agents on-demand capabilities via progressive disclosure: lightweight metadata can load early, full instructions load only when relevant, and supporting resources are accessed when needed.

Platforms that support skills today, plus ready-to-use skill catalogs.
/learn installer.Guides and tools for authoring, validating, and distributing skills.
Evaluation frameworks and deeper technical reading.
Agent Skills are modular SKILL.md packages that provide on-demand capabilities without loading all knowledge up front.
Fine-tuning changes model weights, while skills provide runtime knowledge and workflows that you can update instantly.
Agent Skills focus on workflows and capabilities, while MCP focuses on secure, structured data and tool access.
See the How to Build Skills section for a step-by-step authoring guide.
Support varies by platform, but major tools include Claude (Claude.ai and Claude Code), OpenAI Codex, GitHub Copilot, Cursor, VS Code, and more.
If a platform does not support the format natively, you can often integrate skills via a loader or by adapting the SKILL.md instructions into that platform’s prompt workflow.
Treat skills like code: review them before using, avoid installing from untrusted sources, and prefer audited skill libraries.
The most common approach is to version skills in Git (in a shared repo) and let your supported tools discover them from a standard directory.
