Why software and saas teams adopt this
Default model prose is recognisably uniform, and describing a personal writing voice in adjectives does not reliably change it, so drafts need heavy rewriting to sound like their supposed author.
A Claude skill vets and measures an author's own writing samples, extracts observable stylistic features and AI anti-patterns, runs a calibration loop against generated samples, and emits a voice profile plus a Claude custom Style and Project-instructions block.
