Honestly, don't agree. I think even this is a waste of time and context.

The LLMs will always have these suggestions on things that will "reduce friction in the future" but I really think the LLM is a sycophant glazing you. Because even when you add those skills or prompts at some point the LLM ignores it or does whatever it wants to do anyways. Better to leave most of that out and deal with it when it arises.

Even your example, instructions for running specs... none of the current frontier models need this at all.
