What problem does it solve? Inconsistent, vague, or confusing interface copy erodes user trust and makes products harder to use. This Skill applies a systematic set of UX writing principles to write or review any user-facing text, from button labels to error messages. ## Core Features & Use Cases - Copy Review with Severity Ratings: Audits existing interface text against 12 principles and outputs findings in a structured table with severity, location, before/after, and rationale. - Microcopy Authoring: Writes verb-first button labels, destination-describing links, actionable error messages, forward-pointing empty states, and format-showing placeholders. - Consistency Enforcement: Detects mismatched capitalization policies, inconsistent flow vocabulary, and terminology drift across screens. - Use Case: Before shipping a new settings page, run a review to catch a destructive dialog confirmed with "OK", a toggle labeled with a double negative, and an error toast that says "Oops! Something went wrong" instead of how to recover. ## Quick Start Review the interface copy in my settings and checkout screens and list any findings with suggested rewrites.
