## When to use which

- **skills.sh** is the default installer and the best view of what is popular by installs.
- **SkillsMP** is the widest index if you want to see everything that exists.
- **Agent Coach** is for an agent that should install fewer, scanned items picked for its goal, and drop what doesn't help. Many Upskill items install with the same `npx skills add` command.
