feat(browser): screenshot_page is full-page only — add clip/selector/viewport option #3
Description
Summary
screenshot_page only captures the full page. On a long single-scroll app (~6000px tall in my case) every capture is a huge image even when only a small region (the chessboard) mattered — costly in tokens and latency, and harder to read.
Detail
- There's no
clip,selector, orfullPage:falseoption onscreenshot_page. - The separate
screenshottool does have aregionparam, but that captures the OS screen, not page coordinate space — so it's the wrong tool for a headless browser (nothing is on screen).
So for headless browser work there's no way to capture just the viewport or a single element.
Suggested fix
Add one or more of:
fullPage: false-> capture only the current viewport.clip: { x, y, width, height }-> capture a page-space rectangle (Playwrightpage.screenshot({ clip })).selector: string-> capture an element's bounding box (Playwrightlocator.screenshot()).
Any of these would cut image size dramatically when the caller knows what they care about.
Environment
- Engine: Playwright, headless.
