Frequently Asked Questions
What are Skills for AI agents?
Skills are specialized knowledge modules that extend AI agent capabilities. Each skill encapsulates expertise in a specific domain — security, DevOps, marketing, UX, LGPD — enabling the agent to operate with depth on complex tasks without extensive prompts.
The Agent Skills format is an open standard adopted by thousands of developers globally.
How do I install skills in my agent?
Use the command npx skills add fabricioctelles/skills to install all skills from the repository. You can also:
- Install individual skills:
npx skills add fabricioctelles/skills/humanizar - Clone manually:
git clone https://github.com/fabricioctelles/skills.git - Copy only the desired skill folder to your project
Which agents are compatible with skills?
Skills are compatible with any agent that supports the Agent Skills format:
- Kiro — native support via KiroCrew
- Cursor — place in
.cursor/skills/ - Claude Code — via plugins or local folder
- Windsurf — support via extension
- Others — any agent with custom prompts system
Can I create my own skills?
Yes! The format is simple: a folder with a SKILL.md file containing instructions. Check the skill structure for details. You can publish on Skills.sh or keep it private.
Do skills work offline?
Yes, once installed. Skills are local Markdown files — they don't depend on external APIs to work. The AI agent reads the skill instructions and applies them during the conversation.
What's the difference between skills and system prompts?
Skills are modular specializations you activate on demand (with /skill-name), while system prompts are global instructions always active. Skills allow:
- Context switching without editing configurations
- Combining multiple specialties in one session
- Versioning and sharing knowledge across projects
Are skills free?
Yes, all skills in this repository are open-source under MIT license. You can use, modify, and redistribute freely. The code is available on GitHub.
How do I update installed skills?
Run npx skills update to update all skills to the latest version. To check current version: npx skills list.
