What's with the tool selection by Gemini 3.1 Pro?

I just asked Antigravity to solve a problem, here’s its thinking process:

I’m kind of confused regarding what’s with this “specific tool” selection thoughts. I can see this in every thinking block with some variance (I shall avoid this tool, this tool seems better at the job). In fact, out of the 12 thinking prompt in response, 7-8 were tool selection rather than focusing on the problem.

Does anyone know what’s happening?
