Best Claude Skills
Claude Skills are reusable instruction files that teach Claude Code how to perform specialized tasks. They live in your project as .claude/ markdown files and activate automatically when Claude detects relevant context. Think of them as expert playbooks — from writing tests to generating database migrations — that make your AI assistant dramatically more effective.
Save Hours
Pre-built expertise means Claude gets it right the first time instead of requiring multiple iterations.
Consistent Quality
Skills enforce best practices, coding standards, and review checklists across your entire team.
Easy to Install
Drop a markdown file into your project. No packages, no dependencies, no configuration needed.

What are Claude Skills?
Claude Skills are markdown instruction files stored in your project's .claude/ directory. They give Claude Code specialized knowledge about specific tasks — like writing tests, reviewing code, or generating migrations — so it can produce higher quality output with less back-and-forth.
How do I install a Claude Skill?
Most skills are a single markdown file. Copy it into your project's .claude/ directory (create the folder if it doesn't exist). Claude Code will automatically detect and use the skill when relevant context arises. You can also use our Config Generator at skiln.co/generator to set up multiple skills at once.
Are Claude Skills free?
The vast majority of Claude Skills are open source and completely free to use. They are community-contributed markdown files hosted on GitHub. Skiln indexes over 4,000 skills from multiple curated sources.
What's the difference between Claude Skills and MCP Servers?
Claude Skills are static instruction files that guide Claude's behavior within your project. MCP (Model Context Protocol) Servers are running processes that give Claude access to external tools and data sources — like databases, APIs, or file systems. Skills shape how Claude thinks; MCP Servers expand what Claude can access.
Can I create my own Claude Skills?
Absolutely. A Claude Skill is just a markdown file with structured instructions. Write your expertise as clear, actionable guidance, save it as a .md file in .claude/, and Claude will follow it. You can also submit your skills to Skiln to share with the community.
