Yes, but I have had moderate luck with creating an "agent-instructor" skill that has strict instructions around keeping language strong, unambiguous, concise, and always presenting me with exact diffs to review before writing anything.

Another thing in it is a strict line count. Any increase in line count requires my approval. That last one is important because it plays well with two biases: models don't tend to create long lines so they won't try to cheat that way, and they're strongly inclined to keep churning out lines so I take that away from them.

Did you tell Claude "make an agent instructor skill, whatever you think is good, go for it," or did you use the knowledge you had gained about how AI works and how to write good instructions for it?
