Summary
Automates Next.js version upgrades by walking through the official migration path: detects your current version from package.json, fetches the right upgrade guides, runs the appropriate codemods (like next-async-request-api for v15's async changes), and updates dependencies in the correct order. Smart enough to handle incremental upgrades when you're jumping multiple major versions. The real value is in the codemod automation and the structured checklist, since Next.js breaking changes can be subtle. It chains to the main nextjs skill when it spots Pages Router patterns during migration, which makes sense since most upgrades involve moving to App Router at some point.
