What problem does it solve? Product teams often ship interfaces with inconsistent, confusing, or generic copy — vague error messages, dead-end empty states, and CTAs that don't tell users what will happen. This Skill provides a systematic discipline for UX writing and content strategy so every word in a product is clear, consistent, and actionable. ## Core Features & Use Cases - Voice and Tone Frameworks: Define 3-5 voice principles with boundaries and a tone spectrum across contexts (onboarding, errors, success states) so any writer produces consistent copy. - Error Message and Empty State Design: Structure error messages with what happened, why it matters, and what to do; design empty states that onboard, guide, or recover rather than dead-end. - Microcopy and Content Modeling: Build pattern libraries for tooltips, placeholders, confirmations, and CTAs, plus structured content models that are localization-ready and reusable across contexts. - Use Case: A team preparing a new checkout flow uses this Skill to write the CTA hierarchy, validation error messages, empty cart state, and confirmation dialog copy — all aligned to a defined voice framework and tested for readability and translation readiness. ## Quick Start Review the error messages and empty states in my onboarding flow and rewrite them following UX writing best practices.
