Thanks for sharing your experiences. That's about what I'd have expected. I always found it very weird to see people declaring instructions to LLMs as if they were talking to a person. "Do this", "never do that", as if there was some kind of interpreter behind that built a ruleset to follow. There isn't. It's all just context. Theory would suggest that in the rare cases that these instructions actually achieve the desired effect, they do so more coincidentally than anything else. Easy to see how it could work for something like "Write tests according to pattern X" because there are going to be examples of that around in the training data; highly unlikely that instructions like "don't repeat yourself" or "study the codebase first" would do anything reasonably effective.
