What are Claude skills?
Claude skills are SKILL.md files — plain markdown instruction sets that teach Claude how to perform specific tasks repeatably. Install a skill once and Claude follows it in every session without re-prompting. They work in Claude Code, Cursor, and any agent that supports the skills spec.
How do I install Claude skills?
Most skills install via a single terminal command using npx: npx skills add [skill-name]. Official Anthropic skills are available at github.com/anthropics/claude-code-skills. Community skills install via the plugin marketplace inside Claude Code using /plugin marketplace add [repo].
What is the best Claude skill for developers?
The frontend-design skill (277,000+ installs) is the most widely used. It forces Claude to commit to a distinctive design direction before writing any code, resulting in production-quality UI on the first pass instead of generic AI output.
Are Claude skills free?
Yes — all official Anthropic skills and most community skills are open source and free to install. Some third-party skill marketplaces offer premium skill bundles, but the core skill ecosystem is free.
Can I build my own Claude skill?
Yes. A skill is just a markdown file saved to .agents/skills/ in your project. Write instructions for a specific task, save it as skillname.md, and Claude will use it automatically when the task matches. Anthropic's Skill-Creator skill can help you build and test new skills.
