I'm not sure exactly where you get 12 lines of code from. There are at least a hundred lines of LLM-related "prompt engineering" alone: see https://github.com/slavingia/va/blob/35e3ff1b9e0eb1c8aaaebf3..., for example.

Regardless, number of lines is not an accurate metric of how "essential" a component is to the functioning of the overall system. How about this, try removing the LLM-related code from the script... what functionality is left, exactly?
