Hey, a paper author here :) I agree, if you know well about LLMs it shouldn't be too surprising that autogenerated context files are not helping - yet this is the default recommendation by major AI companies which we wanted to scrutinize.

Can you explain a bit what you mean here? If the context file specifies a desired behavior, we do check whether the LLM follows it, and this seems generally to work (Section 4.3).
