Tools (6)

  • screenshot_url

    Take a screenshot of a web page as it actually renders in a real browser, after JavaScript has run. Use this when you need to see a page rather than read it — checking a layout, confirming a site is up and looks right, or capturing what a user would actually see. Returns a PNG image.

  • rendered_html

    Fetch a page's HTML *after* JavaScript has executed. Use this when a plain HTTP fetch returns an empty shell or a loading spinner — single-page apps, sites that build their content client-side, or anything behind a framework. Returns the final DOM as HTML text.

  • page_diagnostics

    Load a page in a real browser and report what went wrong: JavaScript console errors and warnings, network requests that failed, and the HTTP status of the page itself. Use this when a site looks broken, a deployment might have shipped a bug, or a page loads blank and you need to know why. An agent cannot see a browser's console any other way.

  • accessibility_audit

    Run a WCAG accessibility audit on a page using axe-core in a real browser, and report the violations with the elements responsible. Because it runs against a genuinely rendered page, colour-contrast and other rules that depend on layout and computed colour actually fire — these are silently skipped by audits that parse HTML without a layout engine. Use this to check a page meets WCAG before shipping.

  • inspect_element

    Answer 'why isn't this element showing where I expect?' for a CSS selector on a live page. Returns the resolved box model, computed display/visibility/opacity/position/z-index, colours, whether the element is inside the viewport, and — crucially — whether another element is covering it. These are the values a browser computes after the full cascade and layout; they cannot be derived from reading HTML and CSS.

  • url_to_pdf

    Render a web page to PDF exactly as a browser would print it. Use this to archive a page, produce a document from a rendered report, or capture something for a record. Returns a PDF file.
