# Parameter

Each horse has five different parameters: speed/stamina/guts/temperament/stability.

Speed: This status affects acceleration, cruising speed, and fuel consumption. The higher the speed, the faster the horse can run, but the lower the fuel consumption.

Stamina: Stamina affects total energy and cruising speed. The higher the Stamina, the longer the distance the car can run.

Guts: This status slightly affects cruising speed, total energy, acceleration, etc. The higher the value, the more competitive the driver is. The higher the value, the easier it is to win a race.

Temperament: Temperament affects competition, acceleration, and fuel consumption. The higher the value, the more stable the horse tends to be.

Stability: This is a status that affects breeding. The higher the stability, the more stable the foal will be on average. However, when a horse with low stability is bred, it is rare that a great horse is born that greatly surpasses the parents' status.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://universal-stallion.gitbook.io/universal-stallion-en/about-horses/parameter.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
