Descriptions:
Riley Brown gives a first-look hands-on demo of Anthropic’s Claude Chrome extension — newly updated to run on Claude Opus 4.5, the company’s most capable agentic model at time of filming. The video covers the extension’s core modes: standard step-by-step approval, a “teach Claude” workflow recorder that captures user actions as reusable shortcuts, and a high-risk “act without asking” setting that removes confirmation prompts for fully autonomous browsing.
The most technically interesting segment walks through connecting the Chrome extension to a live Claude Code session running in the terminal, using the `/chrome` flag and managing extension permissions. With the integration active, Brown instructs Claude Code to build a local Hello World web app, then directs the browser extension to navigate to localhost and inspect it. He then escalates to a more realistic test: rebuilding the page as a lead capture form for a Claude Code webinar, having the agent autonomously fill in all form fields end-to-end to verify the flow — which it completes successfully.
The video also covers wiring up a Firebase Firestore backend to store form submissions, completing a full loop from local development through browser automation to cloud persistence. For developers evaluating Anthropic’s computer-use stack or exploring how Claude Code and browser control can work together in a development workflow, this is a practical reference covering setup, permissions, and concrete use cases.
