LangChain launches browser tool for Managed Deep Agents in LangSmith

LangChain introduces browser capabilities for Managed Deep Agents, allowing agents to read rendered page content and click through websites. The browser runs in LangSmith without infrastructure, providing tools like browser_snapshot and browser_run. Agents can now handle tasks requiring web interaction, such as booking flights or testing frontend changes, with an option to hand off control to a human for sign-in.
