Our Commentary ​

The transition from Gemini CLI to Antigravity CLI is a clear sign of Google's commitment to the agent-first paradigm. Unifying tools is generally a good thing for DX, but I'm always wary of forced migrations, especially with deadlines. It's a necessary step for their ecosystem, but I hope the transition is smooth for developers.
