I saw something about there being no negative prompts although I think they are one of the most important things. About the brands, it happens to me that with the simple fact of talking about, for example, a COLA drink, or even a soft drink, I make reference to the PEPSI brand in its colors and logo, maybe not 100% direct but at a glance you can see the brand. An important issue if we want to develop applications where the customer demands to avoid any mention of their competition. I feel you should emphasize this.
