Common questions

What is an AI skill?

A skill is a packaged set of expert instructions that teaches an AI assistant how to do one job well - the method, the frameworks, the output format, and the mistakes to avoid. You install it once, then just hand the AI your raw input and get back a structured first draft.

How is a skill different from a prompt?

A prompt is a single message you paste each time. A skill is reusable: it lives in your assistant and triggers automatically whenever your request matches what it does, so you never re-paste it. Skills encode the full method, not just a one-line ask.

Do these skills work in ChatGPT, or only Claude?

Both. Each skill ships as a SKILL.md file you can install in Claude as an Agent Skill, and the same text pastes into a ChatGPT Project, a Custom GPT's instructions, or a Gemini Gem.

Are the skills free?

Yes. All 70 skills are free and ungated. Download them, copy them, and use them however you like.
