Take a screenshot of a website using headless Chrome. ## Instructions 1. Parse the URL from: `$ARGUMENTS` 2. If no URL given, ask the user for one. 3. Take screenshots with headless Chrome (`google-chrome`, `chromium` or `chromium-browser` — use whichever is installed): - Desktop: `--window-size=1400,900` - Mobile: `--window-size=390,844` (iPhone 14 size) - Always add `--headless --disable-gpu --screenshot=<file> --run-all-compositor-stages-before-draw --virtual-time-budget=5000` 4. Save to `/tmp/screenshot-desktop.png` and `/tmp/screenshot-mobile.png`. 5. Show both screenshots to the user with the Read tool. 6. If the site needs auth/cookies, ask for the cookie header, verify with `curl -H 'Cookie: ...'` first, then pass it to Chrome. ## Tips - For full-page shots use a tall viewport: `--window-size=1400,3000`. - If the user says "full page" / "celá stránka", use the tall viewport. - A flatpak/snap browser may render a wrong (small) viewport — if the image looks tiny, say so instead of pretending it's the real layout.
