This is dumb, you can totally escape the delimiter or use randomized delimiters.

Did you see my example of an attack that defeated the delimiter without using a delimiter at all?

There's no reason why delimiters need to be picked for human readability. Cryptographically random delimiters with adequate entropy seem to guard properly.

See my other comment here: https://news.ycombinator.com/item?id=35926548

The article lists injections that don’t use the delimiters.

Yes totally. This really is no different than any other code injection vulnerability. Only allow symbols that you expect, and don't concatenate user input and logic unless the bounds between the two are guaranteed to be explicit.

this is not correct

> don't concatenate user input and logic unless the bounds between the two are guaranteed to be explicit

Which is achieved how for an LLM?

> don't concatenate user input and logic unless the bounds between the two are guaranteed to be explicit.

Well that's kind of the whole problem - LLM-based agents inherently work by literally concatenating logic with user input, and the bounds aren't guaranteed to be explicit. There is a discussion about finding a way to implement such bounds, but we don't have a good solution yet.
