What problem does it solve? Interface copy is often inconsistent, confusing, or written ad hoc by developers. This Skill produces or reviews UI text — buttons, error messages, empty states, notifications, labels — against a defined voice and tone system so every string is clear, concise, and consistent. ## Core Features & Use Cases - Copy formulas: Buttons frontload the verb and name the outcome; confirmation dialogs restate the action and object; errors follow the what→why→how structure with no dead ends. - Tone matching: Adjusts language to the user's emotional state (onboarding, success, routine, error, destructive), using plainer language under higher stress. - Pre-ship checklist: Enforces a 10-item review covering sentence case, numerals, labels over placeholders, inclusive language, and translatability. - Use Case: When designing a destructive action like account deletion, use this Skill to write the dialog title, a confirm button that restates the action ("Delete account"), and a type-to-confirm step for high-stakes operations. ## Quick Start Ask the assistant to write or review the error message and confirmation dialog copy for a specific UI flow in your product.
