What problem does it solve? Editing user-facing text often introduces subtle errors: numbers get changed, warnings get softened, commands get altered, and unsupported claims get strengthened. This Skill provides a disciplined workflow for drafting, reviewing, revising, and adapting writing without changing what the source is allowed to mean. ## Core Features & Use Cases - Four explicit modes: Compose new text from supplied facts, Assess problems without rewriting, Revise text in the same language, or Adapt it for another locale or audience. - Invariant preservation: Locks quotations, citation markers, numbers, units, dates, commands, code, error codes, product names, warnings, and obligation strength (must/may/should/never) so edits never distort meaning. - Content profiles: Tailored guidance for documentation and runbooks, release notes and reports, app UI copy, error messages, and public or marketing copy. - Use Case: A manager asks you to polish a release note claiming "all devices always sync instantly" while tests passed 87/90. The Skill preserves the exact 87/90 figure, flags the unsupported universal claim, and revises the surrounding prose without strengthening the claim. ## Quick Start Ask the assistant to revise the attached setup guide for new staff while keeping every command, quoted policy sentence, error code, and safety warning unchanged.
