Todo App

A comprehensive todo application with a React Native mobile app and a Node.js/Express backend API. This file was built using Cursor and the Box MCP server. No code was manually written.

In Cursor, we searched Box for the Product Requirements Document (PRD) and for Coding Standards, and asked Cursor to build the app decribed in the PRD being sure to follow the coding standards. To see the documents we used in Box, check out the /sample-docs directory.

In order to prevent cheating the PRD or guidelines to make the build easier, I used the following publicly available examples:

• PRD from Damian Filiatrault at ScalablePath.
• Coding standards download from Google's Github
