🧪 LLM Agent Tests Do Not Guarantee Code Quality

A study based on SWE-bench Verified has shown that the frequency with which LLM agents write tests does not correlate with their success in solving tasks. Instead of using assertions (`assert`), agents more frequently use print commands to observe code state.

🌍 This is a signal to rethink the architecture of Software Engineering Agents: instead of blindly copying human patterns, the focus should shift toward cheaper and more effective methods of code verification.

👤 Understanding that "smart" agents can waste resources on useless actions will help better evaluate the real performance of development automation tools.
