Tell the tool what the task may change and what needs a separate decision. This is a sample training page, using a fictional exercise.

## Try it

- Read the example request.
- Think about the answer you would expect before trying it.

Update only the sample greeting text. Preserve the layout and other text. If the change needs a new dependency, stop and explain why.
```

> **Practice**
>
> Change one part of the example and compare the result. Keep the task small enough to check yourself.

> **Check**
