Apparently this annoying "next step" behavior is driven by the system prompt, since the other day I was running Gemini 3 Thinking, and it was displaying it's thoughts which included a reminder to itself to check that it was maintaining a consistent persona, and to make sure that it had suggested a next step. I'd love to know the thought process of whoever at Google thought that this would make for a natural or useful conversation flow! Could you imagine trying to have a conversation with a human who insisted on doing this?!
