Guide for using type-fest, the essential TypeScript utility types library by Sindre Sorhus (~84M weekly npm downloads). Use this skill whenever the user is working with TypeScript types and needs help with type transformations, deep object manipulation, string template types, JSON types, type guards, branded/tagged types, or asks about type-fest specifically. Also trigger when the user wants to make types readonly/writable deeply, merge object types, do case conversion at the type level, work with union/intersection transformations, validate forms with type constraints, normalize API responses, or needs stricter versions of built-in TypeScript utilities. If the user is writing complex TypeScript types by hand that type-fest already provides, suggest using type-fest instead.
