next-upgrade is a skill for Claude Code from build-with-dhiraj/ai-workflow-framework-portability-kit. It costs 38 tokens per session (925 once invoked), scanned A, original, MIT.

A procedure for upgrading Next.js versions using official migration guides and codemods. Codemods are automated code transformations that update some breaking changes.

In plain words
What is it for?
Use it to identify the current version, plan an incremental upgrade, run applicable codemods, and update Next.js project code and dependencies.
Why use it?
It reduces missed migration steps when moving between Next.js releases, especially across major versions with incompatible changes.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

next-upgrade scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Upgrade Next.js

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

Instructions

  1. Detect current version: Read package.json to identify the current Next.js version and related dependencies (React, React DOM, etc.)

  2. Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation:

  3. Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15).

  4. 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)
  5. Update dependencies: Upgrade Next.js and peer dependencies together:

    npm install next@latest react@latest react-dom@latest
    
  6. 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
  7. Update TypeScript types (if applicable):

    npm install @types/react@latest @types/react-dom@latest
    
  8. Test the upgrade:

    • Run npm run build to check for build errors
    • Run npm run dev and test key functionality
Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
