Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| annotateA | Open a web page with hover annotations. Returns a proxy URL that adds interactive element labels to any page. User opens this URL in any browser to see annotations on hover. |
| get_elementsA | Get all UI elements detected on the currently annotated page. Returns element names, CSS selectors, positions, and sizes. Use this to understand what the user is referring to when they describe a UI element. |
| highlight_elementA | Briefly flash-highlight a specific element on the page so the user can see which element you are referring to. Useful for confirming "do you mean this element?" |
| rescan_elementsA | Force the annotated page to rescan all UI elements. Use this after the page content has changed (e.g. after navigation, DOM updates, or user interaction). |
| inspect_modeA | Toggle inspect mode on the annotated page. When ON, the user can click any element to copy its name. When OFF, the page behaves normally. Use this to help the user copy element names for communicating design changes. |
