>I would love to know how many people are actually using superpowers.

I use them on and off. Also Get Shit Done and Compound Engineering. The best results I got with Compound Engineering but it burns tokens like crazy, especially in the review phase where it does reviews with 5 - 12 agents in parallel - and I like to do a lot of reviews for both the plan and documentation and code.

For some lighter tasks, builtin Claude Code skills like plan mode are enough.
