What issue are you seeing?

The model is annoying wasting my time like crazy, a junior developer will not upset you and make you annoyed as the model doing lately. He eats tokens like crazy, screw my code and try to focus on the easiest things. It has been a nightmare working with lately. Please fix it make the prompt more severe and also make it follow the rules by adding things properly to it's memory. As believe me, it's acting worst than local model. I know you are working hard but it has been wasting my time and my energy. Looking forward for your fix!

Follow the rules and not feel I am vibe coder, my rule is my rule and not him try to do it it's way and the easy way for it and burning tokens for nothing....
