Upgrade Next.js

Upgrade the current project to the latest Next.js version following official migration guides.

Instructions

  • Detect current version: Read package.json to identify the current Next.js version and related dependencies (React, React DOM, etc.)
  • Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation:
  • Codemods: https://nextjs.org/docs/app/guides/upgrading/codemods
  • Version-specific guides (adjust version as needed):
  • https://nextjs.org/docs/app/guides/upgrading/version-16
  • https://nextjs.org/docs/app/guides/upgrading/version-15
  • https://nextjs.org/docs/app/guides/upgrading/version-14
  • Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15).
  • Run codemods first: Next.js provides codemods to automate breaking changes:
   npx @next/codemod@latest <transform> <path>

Common transforms:

  • next-async-request-api - Updates async Request APIs (v15)
  • next-request-geo-ip - Migrates geo/ip properties (v15)
  • next-dynamic-access-named-export - Transforms dynamic imports (v15)
  • Update dependencies: Upgrade Next.js and peer dependencies together:
   npm install next@latest react@latest react-dom@latest
  • Review breaking changes: Check the upgrade guide for manual changes needed:
  • API changes (e.g., async params in v15)
  • Configuration changes in next.config.js
  • Deprecated features being removed
  • Update TypeScript types (if applicable):
   npm install @types/react@latest @types/react-dom@latest
  • Test the upgrade:
  • Run npm run build to check for build errors
  • Run npm run dev and test key functionality

How to use it

Copy the folder

Take vercel-labs/next-upgrade from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.

Install what it needs

The instructions reference npm, npx. Without those the skill loads but fails at the first command.
