edit: GSD is a cli wrapper, Superpowers not so much. Both are over-engineered for an easy problem IMHO.
Otherwise, if you can own your own thinking, orchestrating, and steering of agents, you're in a more mature place.
GSD is a collection of skills, commands, MCPs(?), helper scripts, etc that you use inside Claude Code (and others). If anything, Claude Code is the wrapper around those things and not the other way around.
Re: helper scripts. Anyone doing extensive work in any AI-assisted platform has experienced the situation where the agent wants to update 10k files individually and it takes ages. CC is often smart enought to code a quick Python script for those changes and the GSD helper scripts help in the same way. It's just trying to save tokens. Hardly a wrapper around Claude Code.
