  • All AppWrite operations should include proper error handling and retry logic
  • German error messages should be implemented for all user-facing errors
  • Migration should be thoroughly tested with various localStorage data scenarios
  • Security requirements (encryption, HTTPS, no local credentials) are critical and must be implemented
  • Performance optimizations should be implemented incrementally and measured
