Nitpicks 🔍

🔒 No security issues identified

⚡ Recommended areas for review API Design The route is mounted at /hello on the top-level path. Verify this follows project routing conventions (e.g., API namespace like /api/hello) and won't conflict with other top-level routes or static assets. Consider documenting the new route path or namespacing it.
