## Summary

Managed Deep Agents v0.10 adds browser use, letting agents work on websites that have no API. It also adds async subagents that run long tasks in the background while the agent keeps talking to the user. A browser_handoff tool lets a person sign in to a site directly, so passwords stay out of the model's messages and traces.

most of the web has no API, just pages built for people clicking through them

so! we added a browser to Managed Deep Agents. and when a site wants a login, agents can hand over the window so passwords stay out of the model.

all built in with every MDA https://x.com/i/article/2115851731741347840
