What problem does it solve? Government digital products often ship with inconsistent UI copy: mixed US and UK spelling, title case headings, jargon-heavy sentences, and unclear error messages. This Skill provides a complete set of writing standards so all content accompanying SGDS components follows one consistent, plain-language style. ## Core Features & Use Cases - Style rule enforcement: Covers tone, UK English spelling, sentence case capitalisation, punctuation (including a strict no-em-dash rule), grammar, and plain language principles. - UI copy patterns: Provides ready-made conventions for buttons, error messages, empty states, tooltips, helper text, and loading messages. - Reference lookups: Includes quick-reference files for spelling word lists, grammar rules, punctuation, and word choice for on-demand consultation. - Use Case: When drafting an error message like "You uploaded a file that is too large. Please upload a smaller file.", use this Skill to rewrite it as "The file is too large. Upload a file under 5 MB." ## Quick Start Review this error message and button label against the SGDS writing guide and rewrite them to comply with the style rules.
