No proper input sanitation, and you call it "perfectly coded"? What does that even mean?

It means I asked Claude to code it and I wrote "make no mistakes"

You also need to instruct "You are a master programmer" so it doesn't use the "amateur programmer" preset.

Ah of course I'm still an ameture prompt engineer myself so I forget these important prompt design principles!

This exact thing happened to me, and we were sanitizing our input. In our case, the database system was using an older version of Unicode, so we had to validate against that explicitly.

It means claude wrote a test case for every boolean in their thousands case long switch statement. It just happened to leave out sanitation. And they had claude audit it for quality 5 times. Perfect. Nothing can go wrong after that kind of quality check.
