elmd hooked Claude up to WebContainers via the SDK, giving the agent a full Node environment inside a browser tab — npm install, vitest, and the vite dev server all run sandboxed with nothing on disk. The post also cites adamdotdev's rebuild of OpenCode to run inside browser devtools with console.log statements, part of a wave of 'browser as agent sandbox' experiments.
