What happened
Claude Code has added a built-in browser that can interact with live external web pages from inside the development environment. The browser can read pages, click controls, and type into sites.
Why it matters
The change expands a coding-agent workflow beyond code and local development tasks into web-interacting work. For teams building developer or agent workflows, it creates a new option for tasks that require working with external sites.
Controls and limits
Write actions are screened by classifiers. Purchases and account creation require user approval, making those approval points central controls for any trial of the feature.
The available record describes the capability and its stated safeguards, but it does not provide independent testing, implementation detail, or evidence about how the controls perform across different sites and tasks.
Watch for practical evidence of how the classifier screening and user-approval gates work during real web-interacting tasks.
