I think the main thing which a lot of these articles miss is it's not just your Agents.md which can give you a model upgrade or the inverse.

But everything your harness looks at could be this. So the skills in your code base, the commands that you've added, the memories that were auto created, they all work towards improving or completely destroying your productivity.

And most of it is hidden. You hear people talk about this all the time where they'll be like, Oh, I use GSD or I use Superpowers and my results have gotten worse.

Your results might have gotten worse precisely because you use them (along with your memories and other skills).
