How a Claude Skill works

This is a Claude Skill — a single SKILL.md file Claude reads as instructions for a specific kind of work. Drop it in your Claude Project, your /mnt/skills/user/ folder, or wherever Claude can read it. Claude triggers the skill automatically when your prompt matches its description, then follows the methodology end to end.
