How do you stop AI from making bad architectural decisions in your codebase?

The problem I keep hitting: AI assistants are making architectural decisions - what to import, which layer to touch, which module to put things in - without any understanding of the architecture they're working in. It's not just wrong paths. It's fundamental. The AI doesn't know your module ownership. It can't trace the blast radius of a change. It has no idea which constraints your team has defined or why. It gets files and hallucinates the rest. I built Mikk to fix this - a codebase context engine that parses your TypeScript project and gives your AI the architecture it's missing.
