工具清单
工具（6）
🟢capture_context(url, width, height, dismissCookies)
Returns the structured representation of a web page: visible text with coordinates, interactive elements, forms and tables. Use this to let an agent read and understand a page without parsing raw HTML.

"type": "object",

},
"required": [

}🟡find_elements(url, width, height, dismissCookies)
Returns only the interactive elements of a page (buttons, links, inputs) with role, label, CSS selector and pixel coordinates. Use this before acting on a page (computer-use / Set-of-Marks style grounding) instead of capture_context when you only need to know what can be clicked and where.

}🟡create_semantic_monitor(url, label, schedule, intent, callbackUrl)
Watches a URL on a schedule and reports what changed and whether it matters, explained by AI — not just a pixel-diff percentage. Use this for competitor pricing pages, changelogs, status pages, or any page whose changes should trigger a workflow.
