# Part 4 - Your Message Specification in Action

With a message specification set up, it will be visible in the Messages view.

### 1. Open Messages View:

Use custom tab set at the top of the main workspace to switch back to **Messages** view.

### 2. Start Vehicle Spy:

Click the **Start** button (Figure 1:![](https://cdn.intrepidcs.net/support/VehicleSpy/assets/smOne.gif)) located in the upper left corner.

### 3. Enter Scroll Mode:

Press the **Scroll** button (Figure 1:![](https://cdn.intrepidcs.net/support/VehicleSpy/assets/smTwo.gif)). Notice the **Module Message** description is present, attached to HS CAN messages with Arb ID 110. Select the **Pause** button (Figure 1:![](https://cdn.intrepidcs.net/support/VehicleSpy/assets/smThree.gif)) to see this more easily.

### 4. Enter Static Mode:

Turn scrolling off by clicking the **Scroll** button again. Module Message is displayed in the custom color you selected. Notice the data in the message is changing. This can be spotted easily because of the gray activity highlighting.

# 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://docs.intrepidcs.com/vspy-3-documentation/3.9.16/vehicle-spy-tutorials/tutorial-1-basics-of-vehicle-spy/part-4-your-message-specification-in-action.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.
