Antigravity Streaming (Interactions)

Stream the Antigravity agent's progress (tool calls, intermediate text, generated artifacts) instead of waiting for the final result. Antigravity runs in the foreground, so the stream stays open for the duration of the autonomous loop. No background reconnect is needed.

Code

6agent = Agent(

16        "Read Hacker News, summarize the top 5 stories, and save the "
17        "summary as a Markdown report.",

24            "week and write a one-paragraph blurb for each.",
