Design Engineering

Summary

This helps you figure out what design engineering actually means for your team and whether you need it. It's built on frameworks from folks who created design engineering functions at Snap, Captions, and Vercel. The skill walks you through defining the role (prototyping vs production code), identifying whether your problem is handoff friction or shipping speed, and deciding where the function sits organizationally. Most useful when you're about to post a design engineer job req but aren't quite sure what you're hiring for, or when designers and engineers keep talking past each other. The core insight is that design engineers aren't unicorns who are world-class at both, they're people strong at the intersection.

ui-design

starchild-ai-agent/official-skills

UI/UX quality gate and build guide for every visual output — landing pages, dashboards, web apps, portfolios, and tools. ui-design remains the main entry point. Integration model: ui-design main trunk + taste-skill overlay. - ui-design owns engineering quality (track selection, component-library strategy, accessibility, responsiveness, theming, performance, preview delivery) - taste-skill is invoked inside the ui-design workflow for style decisions (Brief Inference, Design Dials, Anti-slop hard rules) MUST USE together with project-builder whenever a project produces visual HTML/CSS/JS.
