Install

one command, takes just this skill from the repository 
npx skills add https://github.com/aiskillstore/marketplace --skill performance-vitals

How to use it

Copy the folder

Take aiskillstore/performance-vitals from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npx. Without those the skill loads but fails at the first command.
