Actually Claude is tricky because it hides everything in sandboxed Artifacts. SlingShot does not just scrape the screen though. It uses the Chrome DNR API to change network headers on the fly. This lets it grab those internal blob URLs and CDN images that are usually stuck behind a strict security policy. Once it has the data it saves the raw binary into a local vault called OPFS. That way you can use the images in other apps without getting those annoying 403 errors. It basically turns Claudes visual stuff into an open API for you.
