From a skill to something finished

How to use a skill
  1. Choose your task

    Open a skill and read what it helps you do, what you need, and what you should have at the end.

  2. Give it to your AI

    Copy the skill text or share its link with your assistant. Add your own files, context, and goal.

  3. Work through it together

    Your assistant follows the steps. You make the decisions and check the finished result.

A prompt asks for a result. A skill adds the method: where to start, what to check, and when the work is done. Your AI may need access to files or tools for some tasks.
