The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
annotate ~71
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.
| Name | Type | Req | Description |
|---|---|---|---|
| url | string | yes | The target URL to annotate, e.g. "http://localhost:3847" or "localhost:3847" |
No output schema declared.
No examples provided.
get_elements ~48
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.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
highlight_element ~55
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?"
| Name | Type | Req | Description |
|---|---|---|---|
| name | string | yes | The element name or CSS selector to highlight |
No output schema declared.
No examples provided.
inspect_mode ~68
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.
| Name | Type | Req | Description |
|---|---|---|---|
| enabled | boolean | yes | true to enable inspect mode, false to disable |
No output schema declared.
