Is that called jailbreak?

Yeah ! You should close your eyes on dangerous source code nowadays. Think about a kind of DRM for programming. Perhaps the future is a prompt terminal with no access to the source code. Of course the code should be deployed only on a “secure” anthropic platform.

Yes. The biology/infosec fallback to Opus is the jail. Promoting to get around it (in my case accidentally) and have Fabre find exploits is the jailbreak.
