Free Skills for Every AI Coding Tool

Agent skills are markdown files that give AI coding tools context about specific topics — frameworks, APIs, workflows, and best practices. When you add a skill to your project, your AI assistant knows the rules and patterns for that topic. It stops hallucinating deprecated APIs and starts writing code that actually follows current best practices.

Same concept, different file names. Cursor uses `.cursorrules` or `.cursor/rules/*.mdc` files. Claude Code uses `CLAUDE.md` or `.claude/skills/` directory. Cline uses `.clinerules`, Windsurf uses `.windsurfrules`. The content is identical — the only difference is where the file goes and how the frontmatter is formatted. Every skill on this page comes in every format.

Copy the skill content from the Cursor tab, then paste it into a new file at `.cursor/rules/[skill-name].mdc` in your project root. Cursor will automatically load it. For older Cursor versions, paste it into your `.cursorrules` file.

The fastest way is `npx skills add YepAPI/skills` which installs all 110 skills automatically. Or copy a skill from the Claude Code tab and save it to `.claude/skills/[skill-name]/SKILL.md` in your project.

Yes, all 110 skills are completely free. No signup, no paywall. The YepAPI-powered skills (SEO audit, web scraping, etc.) reference YepAPI API endpoints — you need a free API key ($5 free credit, no card required) to use the actual API calls, but the skill files themselves are free.

Only for the 14 YepAPI-powered skills (SEO audit, web scraping, competitor research, etc.). These skills teach your AI how to call YepAPI endpoints for real data. The other 96 skills — like Next.js, React, TypeScript, TDD, security — work standalone with no API key needed.

Yes. Every skill on this page is available in every format: Claude Code, Cursor, Cline, Windsurf, AGENTS.md, and raw markdown. Pick your tool, copy the right format, and paste it into your project. The content is identical across formats — only the file location and frontmatter differ.

YepAPI Skills works like a free, open AI agent marketplace — but without the marketplace friction. There's no paywall, no accounts, no vendor lock-in. All 110 skills are open source on GitHub. Think of it as a curated AI agent platform with tools and configurations that make every AI coding tool smarter. Use them as-is or fork and customize for your workflow.

Cursor extensions add UI features to the editor. Skills work like lightweight Cursor extensions for AI context — they make the AI smarter about specific topics. A Cursor extension might add a new panel. A Cursor rule (skill) teaches the AI how to write better Next.js code, follow your team's conventions, or call YepAPI endpoints correctly. Both are useful — skills are portable across every AI tool, not just Cursor.
