# Cassie Extensions

An extension for Cassie that introduces dynamic variables Cassie is able to read and announce. You can insert them directly into your custom Cassie messages and their corresponding translations. The plugin will automatically parse and replace these placeholders with live game data when the announcement plays.

## Available Variables

* **`{SCPLEFT}`** Returns the exact number of currently living SCP subjects.
* **`{MTFLEFT}`** Returns the total number of alive players belonging to the Foundation Forces (Mobile Task Force and Facility Guards).
* **`{CHAOSLEFT}`** Returns the total number of alive players on the Chaos Insurgency team.
* **`{CLASSDLEFT}`** Returns the number of currently living Class-D personnel.
* **`{SCIENTISTLEFT}`** Returns the number of currently living Scientists.
* **`{ROUNDTIME}`** Returns the total elapsed time of the current round. This variable is automatically formatted into spoken English, adjusting dynamically for singular and plural words (for example: "1 minute and 30 seconds" or "45 seconds").

**Example Usage**

**Message configuration:**

```yaml
cassie_message: "ATTENTION ALL PERSONNEL . {SCPLEFT} SCP ALIVE . TIME {ROUNDTIME}"
cassie_translation: "Attention all personnel. {SCPLEFT} SCP subjects remain. Time elapsed: {ROUNDTIME}."
```

## 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.uct.ucserver.it/custom-teams/configuration/cassie-extensions.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.
