Asset check
Four things break in every interface an agent builds, and none of them shows up in a screenshot review: emoji doing an icon's job, a page of cards with no picture in it, an image URL that died two years ago, and an icon import that will stop compiling on the next library major.
All four are mechanical. Each has one answer, yes or no. Run them without being asked, the moment a UI is built or changed.
Scope
This skill owns the asset sweep: what is on the page, where it came from, whether it exists. ui-polish owns how it looks (size, stroke, alignment, contrast), ux-check owns whether a state exists at all, ux-writing owns the words.
One contested line, settled here: the icon census (finding everything doing an icon's job, including emoji, text glyphs and CSS shapes) is this skill. ui-polish judges the icons that remain.
