Indeed. I've been using Superpowers, GSD, and I'm starting to test if I can fit it into my flows.

Each one has its purpose and if you install all of them, dont forget to tell the model which one you want it to use. I have once left claude on YOLO and when I came back I had a bunch of subagents working, burning my beloved tokens because each one had to get context all again. And simple tasks that should have been done inline. And Claude gave me passive agressive answers when I asked why it decided it. I laughed and then played League of Legends for the next 4:30h.

I tried using them both for a while but I actually turned Superpowers off a few weeks ago and haven't used it since. I found that I would have a ready-for-agent task well-specified and ready to go and then after telling Claude to do it, it would load up brainstorming and start making a multi-step process to plan things out with a design doc, etc., when really all I needed was for Claude to just execute on the already-laid-out issue.
