Show HN: Algebruh - Cross-check arithmetic claims with Z3, cvc5, and Lean (github.com)

Nice, but what is the motivation for this? That the syntax is perceived to be nicer than SMT-LIB format? Or that Lean can get involved? Differential testing? Just for fun?

Readme is mostly install and usage information but not much above the use case.

OP - could you fill in why/when one would use it?
