Full Page Screenshot

Capture a full-page screenshot of any web page via Chrome DevTools Protocol. Produces a single PNG that includes all content — even portions that require scrolling. Zero external dependencies beyond Node.js 22+ and Chrome with remote debugging enabled.

Prerequisites

Node.js 22+ (uses built-in WebSocket)

Chrome/Chromium with remote debugging enabled

Check environment readiness:

node "${SKILL_DIR}/scripts/full-page-screenshot.mjs" --check

If Chrome check fails, instruct user to open chrome://inspect/#remote-debugging and enable "Allow remote debugging for this browser instance".
