When you run Antigravity the first time, it asks you for a profile (I don't remember the exact naming) and you what it entails w.r.t. the level of command execution confirmation is well explained.
Yeah but it also says something like "Auto (recommended). We'll automatically make sure Antigravity doesn't run dangerous commands." so they're strongly encouraging people to enable it, and suggesting they have some kind of secondary filter which should catch things like this!
