Frequently Asked Questions
Common questions about skills answered.
What is a Claude Skill?
A Claude Skill is a SKILL.md file that teaches Claude Code, Cursor, or Windsurf how to perform a specific task. Skills contain structured instructions — coding standards, step-by-step workflows, or domain expertise — that the AI follows whenever you ask it to do that task. They're the fastest way to customize your AI assistant without writing prompts from scratch.
How do I install a Claude Skill?
To install a Claude Skill, copy the SKILL.md file into your project's .claude/skills/ directory (for Claude Code) or .cursor/skills/ directory (for Cursor). Then restart Claude Code or reload your IDE window so the skill is picked up. Some skills include a one-line install command you can run directly in your terminal.
Are Claude Skills free?
Yes — all Claude Skills indexed on ImAiFox are open-source and free to use. They're hosted publicly on GitHub under various open-source licenses. You can inspect, modify, and use them in any project.
What's the difference between a Skill and a Prompt?
A Skill (SKILL.md) is Claude-specific — it integrates directly into Claude Code's skill system and is invoked automatically for relevant tasks. A Prompt is a general instruction set (like .cursorrules or SYSTEM_PROMPT.md) that works with any AI assistant. Skills offer deeper integration; prompts offer broader compatibility.
How many Claude Skills are available?
ImAiFox indexes hundreds of Claude Skills sourced from public GitHub repositories, verified for quality and actively maintained. New skills are discovered and added automatically every hour.
