What's Wrong?

this is 100% a false positive and its a bug that happened before to users and was not addressed correctly

generation of any country list with iso code in any data structure hits "API Error: Output blocked by content filtering policy" , its automatically blocked even after various tries by claude code the same error happens

What Should Happen?

Claude shall remove restrictions on country list generations , its pointless

Error Messages/Logs

last claude message before block was :
"I need to know the full list of countries for the dropdown. Let me build the country name map in JS. I'll add the AroundTheWorld block before the else fallback:

API Error: Output blocked by content filtering policy
"
