# Hello World

## Purpose

A tiny reference skill. It shows the exact frontmatter and section layout
that `skillhub lint` expects, so you can copy it as a starting point.

## When to use

- When you want a known-good SKILL.md to test tooling against
- When teaching someone the Agent Skills format

## Instructions

1. Read the user's name from the request.
2. Respond with a friendly greeting: `Hello, NAME!` (substituting the name).
3. If no name is given, greet the world: `Hello, world!`.

## Examples

Input:

```
greet Ada
```

Expected behavior:

```
Hello, Ada!
```
