Borrowed from Garry Tan's gstack, this gives you a senior designer checkpoint before merging UI work. It scores your design across multiple dimensions on a 0-10 scale, tells you what a perfect 10 would actually look like for each one, and calls out AI slop signals (the generic, soulless patterns that scream "I asked ChatGPT to design this"). Think of it as a pre-commit hook for design quality. The ratings are opinionated, which is the point. You want something that pushes back when your button hierarchy is weak or your typography feels like every other SaaS dashboard. Works best when you need structured feedback fast, not just "looks good" in Slack.
