Very neat.
Although philosophically I prefer the unix approach of "do one thing and do it well", I really admire this tool. I think it might be the fact that the one thing this does well is curating a set of functions for a particular profile of developer. My story is someone doing web focused full stack development?
It might be worth doing a survey of your users to see what they use ut for and what areas you should focus on next.
I think for packaging it's okay to "have" lots of things that individually "do" one thing.
The important part is that the user controls the entry points. It's more Unixy to allow someone to decode audio from one pipe to another than to only allow them to play a file to a speaker.
Consider that Debian "does" lots of things because it has a kernel, hardware abstractions, a userland, a package manager, and often a GUI and web browser. But it also "does" none of those because it's just a convenient and useful wrapper to publish all the other tools, which you can still call upon individually
I agree. This feels like a level two busybox/toybox. Nice job.
