Next.js Upgrade

Upgrade Next.js projects to v16 without burning context on detection logic and build mechanics. Everything deterministic is handled by scripts. Your job is to run them, interpret the JSON, and make the code changes.

Why Scripts Handle Detection and Measurement

Scanning package.json, checking lock files, parsing build output — that's pure mechanics, not reasoning. These scripts handle it so you don't have to reconstruct the project state from scratch every time.

Quick Start

Three scripts. Run them in order.

Step 1: Detect project state

bash <skill-path>/scripts/detect-nextjs.sh /path/to/project
