What's Wrong?

This version is such a massive step backwards, in so many ways, I don't know where to start. I actually think multiple versions have been degrading but this is my limit. It's not about consumption, it's about dumb behaviour. This version understands nothing, recalls no protocols and cannot (even with directed prompting} get back previous context / MCP background knowledge equivalent status. It's degrading. And struggling with over-using tokens to grasp previous context concepts. It's embarrassing. I want out, right now.. Another round of this, and I'm prepared to start fresh with another model. I can't believe I built all this memory/DN infrastructure to be confronted with such a basic service. I feel like you played the drug dealer game.... Get them hooked.. then sell them the same shit.. but double the price.

What Should Happen?

Don't get me started..
Claude needs to be same / better than it's predecessor
