From the source SKILL.md

Use this skill when the task is to move a NestJS app across versions: a major @nestjs/* bump, a platform-adapter swap, an RxJS or TypeScript bump driven by Nest, or triaging the breaking changes that come with them. The goal is an ordered, reversible upgrade plan where each step has a verification check and a rollback path, so the app never sits in a half-migrated, unverifiable state.
