# Manage chat history

Cortex Agentic Assistant helps you keep track of your investigations by organizing your chat history for easy review and continuity.

Your chat history is listed to the left of the prompt. The chat history is organized by periods: Chats from today, yesterday, the last seven days, and older. To continue a previous investigation or review a past conversation, scroll through the list and click on the chat you wish to resume.

By default, the first prompt you enter in a new chat becomes its title in the history. To edit the chat title or delete a chat that is no longer relevant, click ![three-dots.png](/files/gHHbrKy5jm4WlNwZ9gqX) and select **Edit** or **Delete**.

{% hint style="info" %}
**NOTE**

Chats and related artifacts are retained for six months (186 days). You can extend the retention period by purchasing a retention add-on.
{% endhint %}

**Slack sessions**

Slack sessions follow a timeout policy of two weeks of inactivity (matching the UI data retention policy), after which the session automatically closes.

# 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://cortex-docs.paloaltonetworks.com/cortex-xdr-5.x/detect-investigate-and-respond-to-threats/agentic-assistant-chat/manage-chat-history.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.
