critique-microcopy

Reviews error messages, empty states, and other short user-facing microcopy strings against NN/g's error-message guidelines, operationalized into the 14 NNG-EM-* criteria in references/NNG-EM.md: where and how prominently a message appears, what it says, how much work it leaves the reader, and whether a total failure still leaves some goodwill.

Narrow artifact claim. This skill's artifact format is annotated screens described in text, placement, container, timing, and behavior notated alongside each message, per ADR 0018 (microcopy artifact format), which chose that format over a bare string list precisely because eight of the fourteen criteria have nothing to read without it. A bare list of strings is still accepted as degraded input, at the coverage cost pass 2 below states; it is not the format this skill is measured on. Either way, this skill does not critique live applications or rendered screenshots: a screen's context arrives as structured text annotation, never as an image, and "the button looked wrong" is out of scope because nothing in the artifact states what the button looked like. See references/NNG-EM.md, "Artifact format", for the exact annotation grammar.
