What You Asked Claude to Do

Claude code dan sadece linux uygulaması yapmasını istedim ama proje mimarisini bile kendi başına halledemedi

What Claude Actually Did

claude code kullanırken benim için linux masaüstü uygulaması geliştirmesini istedim ama sürekli değişikliğe giderek ve benim önceki talimatlarımı gözden kaçırarak kötü bir iş yaptı ve bununla 2 günümü kaybettim chatgpt claudenin yapamadığını 1 saatte yaptı ve projemi tamamladım

Expected Behavior

Linux desktop GUI development task (PySide6 + Python):

Claude Code took 2 days for a partial Orchestrator implementation with multiple thread-safety bugs (no QMutex, no strong worker references) and broken constructor compatibility
ChatGPT delivered the same architecture in 1 hour with proper thread safety, backward-compatible page interfaces, and a cleaner observable cache (AppState with built-in Signal)
Claude Code missed common Linux deployment realities: PEP 668, debconf non-interactive mode, needrestart auto-mode — had to rewrite setup.sh 3 times
Claude Code makes architectural decisions unilaterally (added "auto-execute for low-risk" without discussing security tradeoff)
