Gemini models increasingly stucking in thinking loop

Using Google Antigravity and Google AI Studio, I have noticed that Gemini models, which includes 3.1 Pro and 3.5 Flash, are increasingly stucking in thinking loops. It has become much more common. So I did a 100 tasks test and out of them, 3.5 Flash got stuck in a loop 23 times, while 3.1 Pro was a lower 16 times.

All the tasks done were in Google Antigravity 2.0.

Getting stuck

Was this not the case earlier? I've had it stuck in loops from day 1, even when Gemini 3 came out. I've never been able to actually use it for anything because it goes absolutely mental after a handful of turns.

conflicting instructions in prompts and though signatures being passed down across toolcall chains solved this for me

xnx

Do you have a single example?

I dunno about stuck, but I get a lot of errors that prevent me from submitting new prompts.

Do you have a website available to show the sessions ?

I find when I use Gemini Web Chat that it often just starts over mid-conversation and doesn't remember the rest of the context of the conversation whereas Claude and ChatGPT never do that.
