copy

Voice and copy for every word a user reads. Use when writing or reviewing UI strings, empty and error states, buttons, toasts, push notifications, emails, onboarding, marketing headlines, or App Store text. Also use when the user says copy sounds "generic", "AI-written", "off-brand", "slop", or asks about tone, humor, em dashes, microcopy, or naming a button. Companion to the design skill: design owns pixels, this owns words.
