I still think minimal is appropriate in this case as it shows only what’s relevant in the context.
Some things that you use regularly should be kept as minimal and as stable as possible. To me that includes the shell prompt, editor, browser for example.
If you need to invoke a program for every prompt, when the alternative is to just let the shell do it's thing, it's no longer "minimal", period.
No, we are not. "minimal" has a defined meaning, and "minimal" and "minimalism" as a design philosophy are not the same.

It looks like this:I see one dictionary definition is "the least possible". Seems like the least possible prompt is no prompt at all, but it's really just a matter of opinion ;)
