About this item
A single .cursorrules that tells an AI coding assistant how to work in a Next.js App Router codebase written in TypeScript. It lists the commands to run, the project layout, 8 conventions, testing expectations and the mistakes to avoid, followed by a short working-style section.

Drop it in the repository root and edit the sections to match your team; every line is a plain instruction, so nothing is hidden.
