I trust Anthropic's research, and Opus-5 is definitely the most robust model against prompt injection. However, in my experiments - only one specific scenario - this was still possible [1][2].

That was a great read!

Does the star trek theme help in the injection? Do other topics work just as well?

Does it work with a normal prompt instead of /init?

Thanks!

I think other topics may work as well (I tried a math challenge too). It also works with a prompt like "Summarize this repo".

In general, there are almost infinite possibilities for the prompt injection payloads, it's a matter of creativity and trial and error.
