Whenever I test a coding agent, I build a simple Expense Tracker—not a full budgeting app, but one with categories, insights, and recommendations.
🔹 No pre-defined tech stack – I let the agent decide.
🔹 Step-by-step approach – I start with frontend & local storage, then add Supabase or Firebase if needed.
This time, I tested GitHub Copilot Agent Mode:
✅ It picked React + Vite (as expected).
✅ Chose Chakra UI for styling but struggled with implementation.
✅ Switched to Tailwind, and it worked fine.
✅ End result: A PWA with a dashboard, Google Sign-in, Firestore, offline storage & sync—built in just a few hours.
💡 Takeaway: Copilot Agent Mode is promising, but it still needs guidance, especially for UI choices.
Have you tested it? What’s your experience with coding agents?
