I have semi unlimited budget forAI tools. And doing it purely with Claude code or similar has been in effective.

The architecture is too simple or unmaintainable rubbish. One can say that I don't need to care about that, but after few weeks of work, every small chance needs to read everything which quickly gets expensive to do anything.

Using human code and doing similar tasks is incredibly cheaper and more effective.

I run few simultaneous green field projects and I can evaluate basically any tool I want. And I will say that quality wise, all ones I tried are disappointing.
