# Hook Message Interception

- [Hook Message Interception](https://docs.maiagent.ai/maiagent-user-guide/maiagent-user-guide-en/hook/hook.md): Automatically intervene before user messages reach AI and before AI replies are sent — mask PII, block malicious prompts, and ensure response quality. Enforced at the system level without relying on A
- [Create and Configure Hooks](https://docs.maiagent.ai/maiagent-user-guide/maiagent-user-guide-en/hook/setup.md): Create a Hook from a standard template, adjust parameters (keyword blocklists, judgment models, block messages, etc.), and link it to an AI assistant.
- [Hook Execution Logs](https://docs.maiagent.ai/maiagent-user-guide/maiagent-user-guide-en/hook/execution-logs.md): View logs for each Hook interception or modification, control whether original message content is recorded, and trace Hook execution details for individual messages from conversations.

## 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.maiagent.ai/maiagent-user-guide/maiagent-user-guide-en/hook.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.
