Good idea! I have been manually copying my resume source into ChatGPT for feedback, but a script seems much nicer. Also, I didn't know about how you can render the markdown output using glow.

I recently rewrote my HTML resume into LaTeX, since I was wanted to make sure it could be easily parsed by automated systems. I'm not sure how much of a difference it makes, but it gives me an outline of the sections in the Firefox PDF viewer sidebar.
