Real examples, graded
WeakUnsafe SQL migration review (Northwind) 26/100
“The review contains major false positives and hallucinations regarding PostgreSQL column dropping behavior.”
WeakRace condition in a job worker (Northwind) 16/100
“The suggested UPDATE with a subquery is silently wrong and retains the exact race condition it claims to fix.”
WeakExtract duplicated logic 55/100
“The primary refactored version is correct and minimal. However, the provided alternative decorator solution contains a hallucinated/undefined function name (`@validate_email` instead of `@_validate_email`), which will cause the code to crash with a NameError immediately upon execution. As a severe reviewer, providing broken code in an alternative solution is a major correctness failure.”
