Maybe a linter is a more accurate allegory. I think there are parts of art that could sometimes be suggested in terms of anatomy, symmetry, shading, color theory, etc. You'd configure your art linter to your preferences/style (or target style) and it would point out the things you're doing wrong and offer suggested fixes.
