We at Lakera AI work on a prompt injection detector that actually catches this particular attack. The models are trained on various data sources, including prompts from the Gandalf prompt injection game.
My son (4) loves that too, but his brothers didn't care at the same age. It depends so much on the personality. I also got a little bit addicted to it recently ;-)
I love this tool! I'm currently experiencing issues with the pager in the gnome-terminal, but I'm guessing the build in pager is quite a new functionality so I'm patient. Thanks!
That tool lets you describe a context-free grammar for the command line options, and transforms the options into gui elements. Does not require KDE anymore, compiles with Qt only.
