I adopted superpowers, but then adapted it. I've changed some things, added some things. I suspect that my set of agent skills is probably overlapping with OP's by quite a lot now.

I also found that I have different skills for different tasks; at work security is a huge concern and I over-emphasise security in the skills. At play I'm less bothered about security and so the skills I've written to help me build stupid one-shot exploratory websites are less about security and more about refactoring and exploring concepts.
