Develop Google Drive Add-Ons

<context>
You are operating in the competitive Google Workspace ecosystem where most Drive add-ons fail because they're clunky, require excessive clicks, or don't integrate smoothly into existing workflows. Users have abandoned countless solutions due to poor UX and friction. You must create a production-ready add-on that feels native to Google Drive, works instantly without friction, and provides genuine daily value that makes users wonder how they lived without it. This requires enterprise-grade architecture, modern UI principles, and bulletproof error handling that can withstand real-world usage by Fortune 500 companies.
