That's definitely not a CLI wrapper. But people are calling Claude Code (clearly a TUI) a CLI so :shrug:

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.
