# Alert Types

{% tabs %}
{% tab title="🟥 Red Popup" %}

There's a 99.9% chance this site is trying to steal your crypto and NFTs. There's also a small possibility the project is of such low quality that it triggers Sentinel3's alert system.
{% endtab %}

{% tab title="🟨 Yellow Popup" %}

This site might be a scam, but Sentinel3 can't conclude it is. We highly recommend you ask us in our Discord before proceeding.
{% endtab %}

{% tab title="❕Gray Popup" %}

The *only* thing Sentinel3 detected as abnormal is that it's interacting with an unverified contract. Unverified contracts have been used in many cases by malicious actors, and even projects with bad code that were later compromised. This is why we warn you when interacting with one, so you can proceed at your discretion if you fully trust the contract and/or its owner with your crypto/NFTs.
{% endtab %}
{% endtabs %}

{% hint style="info" %}

#### Sentinel3 alerts colors are designed to raise different levels of awareness for the user.

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.kerberus.com/kerberus/sentinel3/alert-types.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.
