I am a bit surprised that the reported bug through Claude Code does not redact PII.

I'm stuck with the same problem whether I use VSCODE or CURSOR on Windows. I've found loads of these threads opening up but they generally seem to be getting automatically closed/locked and redirected to the below one:

#1251

Hopefully someone can find a solution as it is driving me crazy!

You can do something similar with AHK on windows too.
