If multiple providers of a single category apply, the first one that was registered will be used. Custom registered providers always take priority over the built-in providers. ### **GuiTransformer** A `GuiTransformer` is a handler that maps a generated gui entry to a new gui entry. It can also apply some modifications to the passed entry and return the same reference. ``` registry.registerAnnotationTransformer(...); // apply based on the presence of an annotation registry.registerPredicateTransformer(...); // apply based on a certain Predicate ``` All matching transformers are applied in order of registration. Custom registered transformers always apply before built-in ones. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://shedaniel.gitbook.io/cloth-config/auto-config/custom-gui-handlers.md?ask=&goal= ``` `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.
