What problem does it solve? Product teams often ship interfaces with inconsistent, confusing, or untranslatable copy because no one owns the words. This Skill provides a systematic discipline for UX writing and content strategy so every label, error, and empty state communicates clearly and consistently. ## Core Features & Use Cases - Voice and Tone Frameworks: Define 3-5 voice principles with boundaries and a tone spectrum across contexts like onboarding, destructive confirmations, and success messages. - Error and Empty State Design: Structure error messages with what happened, why it matters, and what to do; design first-use, no-results, cleared, and error-caused empty states with actions. - Microcopy and Content Models: Create reusable patterns for tooltips, placeholders, CTAs, and confirmations, plus structured content models with localization-readiness and inclusive language guidance. - Use Case: A team preparing a new settings flow asks for a copy deck; the Skill delivers screen-by-screen copy, an error message inventory, and CTA language with localization flags. ## Quick Start Ask the assistant to review the error messages and empty states in your onboarding flow and rewrite them using a consistent voice and tone framework.
