no. gemini's instruction following is currently abysmal. Gemini CLI could be a great scaffold for all we know, but we cant know because the models it uses are so horribly bad at being driven in that way.
no clue why google has dropped the ball this hard on IF.
They have a 3.1-pro-customtools model which they allege its better at using custom tools/MCPs/etc.
It is not better.
