Antigravity App 2.31 previews /swarm and adds browser download approvals
Google's Antigravity App 2.31 adds a preview /swarm command for parallel subagents, browser-download approval controls, remote-project setup, voice summaries and MCP app file editing. It also prevents browser pages from locking the pointer or keyboard and adds split-view plugin controls.
Why it matters: Parallel agents and browser downloads widen both execution scale and data-ingress authority. A named approval boundary and input-lock restriction make two concrete failure paths testable before teams enable swarm work or authenticated browsing.
