# Measurements

The simulation will automatically track some general metrics. This is where you'll add the metrics you are looking to track. There's no downside to tracking more metrics, so we suggest you track anything and everything that may be interesting or important, including metrics which may reveal whether the simulation is running as close to how humans would play as possible.

## AI Suggestions

You can allow the AI to set the metrics for you. Enter the things you want to track in human language and/or a list, and click the "*Export AI Instructions*" button. Your text is included in the file exported. Once again, pass this to your AI, and paste the response to "*Import*" it.

## Add Manually

You can also add manually. Select what kind of thing to track, the target, and the label (human readable), and click the "*+ Add*" button.

# Agent Instructions
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://cardstock-studio.gitbook.io/docs/test/measurements.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.
