What it does

Next.js is a popular framework for building websites and web apps. This skill gives the AI agent background knowledge about Next.js 16 and later, which use Turbopack (a fast bundler written in Rust) by default during local development. When you ask for help with slow dev startup, hot reloading, or large bundles, the agent can explain when to stay on Turbopack, when to fall back to webpack, and how to start looking at production bundle size.

Great for

  • Developers building or maintaining Next.js 16+ projects who see slow dev startup or slow hot reloads
  • Teams deciding whether to keep Turbopack or switch to webpack for a plugin or bug
  • Developers trying to reduce large JavaScript bundles in production

Skip it if

  • Projects not using Next.js, since the guidance is specific to it and its bundler
  • Anyone needing exact flags or production build behavior for their version: the file itself tells you to check the official Next.js docs, so the agent's answers may be out of date for newer releases

Try asking

  • “My next dev server takes forever to start, how can I speed it up in Next.js 16?”
  • “Should I switch from Turbopack back to webpack for my project? A plugin I need only works with webpack.”
  • “Help me find which dependencies are making my Next.js production bundle too large.”
  • “Explain how Turbopack's file-system caching works and where it stores data.”

    Ask for the task

    No special command needed — the agent reads the skill's description and loads it when your request matches. Try one of the prompts above.

Get better results

  • Give the agent your Next.js version, since flags and defaults differ between releases.
  • Paste the actual error or slow-startup symptom so the agent can match it to the right advice.
  • Verify flags such as --webpack or --no-turbopack against the official Next.js docs before relying on them.
