Assess and upgrade a Next.js project after resolving the target release from current official documentation. Includes tested automation and breaking-change guidance for the Next.js 15 to 16 migration. Use when the user says 'upgrade Next.js', 'migrate to Next.js 16', 'update my Next.js app', 'run the Next.js codemod', 'my Next.js version is outdated', or when a migration plan or baseline build comparison is needed.

Works with any agent that supports SKILL.md skills.

What this skill can do

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'nextjs-upgrade' ] || [ -L ~/.agents/skills/'nextjs-upgrade' ]; then echo 'A skill folder named nextjs-upgrade already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/b-open-io/prompts' "$d" && git -C "$d" checkout --quiet 'f4b302aadb0c99023b03e1f1b38ffed3697fbedf' -- 'modules/web-dev/skills/nextjs-upgrade' && mkdir -p ~/.agents/skills && cp -R "$d"/'modules/web-dev/skills/nextjs-upgrade' ~/.agents/skills/'nextjs-upgrade' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'nextjs-upgrade' ~/.claude/skills/'nextjs-upgrade' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
