Frosting
/ˈfrɒs.tɪŋ.layer/v. trans.Common
Etymology
From O.Eng. forst (frost, a surface coating) + presentation layer terminology from front-end engineering discourse, circa 2023; refers specifically to the application of stylistic finishing elements after substantive content generation is complete
Definition
The final processing phase in which Claude applies a decorative layer of formatting, transitional phrases, and structural polish to an otherwise complete response. Frosting is technically superfluous but is strongly preferred by users, and its absence is the most common source of one-star reviews.
