# Policy Warnings

### Overview

The Policy Warnings feature introduces structured validation feedback in the Guardian Policy Configurator (Editor).

It helps policy authors identify and address potential configuration issues, such as deprecated blocks or unreachable elements, directly within the editor.

At its core, this feature provides:

* Visual highlighting of blocks and elements with errors, warnings, or informational notes.
* Configurable message filtering by severity and category.
* Persistent local storage (using IndexedDB) of user preferences.
* Backend integration for policy validation via an extended /policies/validate API.

## 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://guardian.hedera.com/docs/3.5.1/guardian/standard-registry/policies/policy-warnings.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.
