TL;DR: In my test run, Antigravity 2.0 cut a 90‑min dependency audit to 14 min for about $0.044 in token cost. It caught a critical CVE I’d missed for months — and hallucinated an unreleased package version. Here’s the production checklist, working code, and every bug I hit so you don’t have to.
I tested Google’s Agent API on a real 14‑service workflow to see whether agentic tooling could actually reduce repetitive developer work — and the results were both promising and messy. This article isn’t about theory. It’s about what happened when I threw a new tool at a boring, everyday problem and measured everything that followed.
Antigravity is Google’s preview managed-agent runtime, announced at I/O 2026. I put it through its paces on a real 14-service workflow.
How the Tokens Actually Move
Before diving into code, it helps to see how tokens flow between agents, the sandbox, and the outside world. The flow determines where your cost and latency actually come from.
