Runs an interactive design critique on your plan before you ship it, scoring UI/UX decisions across dimensions like layout, accessibility, and interaction patterns on a 0-10 scale. For each dimension, it explains what would make it a 10 and then updates the plan to get there. Works in Claude Code's plan mode, so you're reviewing designs before they're implemented rather than fixing live sites (use /design-review for that). Part of the gstack toolkit. Proactively suggests itself when it spots a plan with UI components, which is handy because it's easy to forget design review until you're already debugging CSS. Think of it as a designer looking over your shoulder while you're still in the planning doc.
