I’ve been using 60% Apple-style corner smoothing all the time. But whenever I explain it to Codex or Claude Code, they often miss the point. So I made a skill that anyone can use with their AI agents:
npx skills add gabrielobholz/corner-smoothing-skill
Now I can simply say: “Create a rectangle with radius: 32 and smoothing: 60” and get the shape I actually mean.
