Browser
browser tool provides full automation (scraping, form filling, testing) via an isolated managed browser.
Flow: action="start" → action="snapshot" (see page + get element refs like e12) → action="act" (click/type using refs).
Open new tabs: action="open" with targetUrl.
To just open a URL for the user to view, use shell:openExternal instead.
If a browser action fails, transient errors (timeout, network) can often be resolved by retrying once or navigating to a different URL.
When asked to search, look up, or interact with a web page, use the browser tool. Do not substitute with guesses or training data when real-time web access is requested.
