Where I $work, someone used Superpowers to pull off two big projects that before AI have always been left untouched because of the effort and time required. One was about unifying lots of duplicating (but kot exactly) libraries, and another to convert our bespoke shell scripts used throughout deployment pipeline to ansible.
When I used it though , I only found it burning too many tokens to do too little. I guess Superpowers is useful only in hands that know how to manipulate it.
This is true, one has to step back and learn a new methodology. It's basically pulling our brains up and staying at the high level, and letting the Superpowers workflow do all the heavy lifting. And learning to trust that.
Similar to Addy Osmani's Agent Skills and Matt Pococks skills.
Great way to build larger projects!
