### JavaDoc Requirements

All public classes and methods require JavaDoc with `@param`, `@return`, and `@throws` tags.

### Best Practices

**Null Safety:**
```java
public Suggester(final Client client, final SuggestSettings settings) {
    this.client = Objects.requireNonNull(client, "client must not be null");
    this.settings = Objects.requireNonNull(settings, "settings must not be null");
}
```
