Documentation
Everything you need to discover, install, and create AI agent skills.
Installing Skills
The quickest route is the skills CLI, which resolves any GitHub repository and installs into whichever agent you are running.
Any agent (recommended)
Claude Code plugin marketplace
Then run /reload-plugins inside Claude Code.
MCP servers
If the server publishes to npm under a different package name, use that instead — check the repository README.
Cursor / Copilot / Windsurf
Copy the skill content into your project's .cursorrules, .github/copilot-instructions.md, or .windsurfrules file.
Gemini CLI
Place skill files in .gemini/skills/ as a folder with a SKILL.md file.
What are AI Agent Skills?
AI agent skills are instruction files that teach your AI coding assistant new capabilities. They're simple markdown files with structured instructions — like plugins but portable and transparent.
Common skill file formats include:
- SKILL.md — Standard skill definition (Gemini CLI, universal)
- CLAUDE.md — Claude Code project instructions
- .cursorrules — Cursor AI rules and behaviors
- .claude/commands/*.md — Claude Code custom slash commands
Quality Scoring
Every skill on SkillAgent.dev receives a quality score from 0–100, calculated from:
- Community trust — GitHub stars, log-scaled and capped at a fifth of the score, since popularity describes a repository rather than a skill
- Substance & structure — Length of the actual skill file, and whether it is organised into sections with worked examples
- Activity — How recently the skill was updated
