I honestly tried this a while back, unless this is something else, this was completely not very much useful thing.

If I remember correctly, it created a lot of changes, spent a lot of time doing something and in the end this was all smoke and mirrors. If I would ever use something like this, I would maybe use BMad, which suffers from same issues, like Speckit and others.

I don't know if they have some sponsorship with bunch of youtubers who are raving how awesome this is... without any supporting evidence.

Anyhow, this is my experience. Superpowers on the other hand were quite useful so far, but I didn't use them enough to have to claim anything.
