This is the security equivalent of telling it to not make mistakes. > Restrict downstream tool usage and permissions for each agentic use case Reasonable, but you have to actually do this and not screw it up. > Harden the system according to state of the art security "Draw the rest of the owl" You're better off treating the system as fundamentally unsecurable, because it is. The only real solution is to never give it untrusted data or access to anything you care about. Which yes, makes it pretty useless.

Agree for a general AI assistant, which has the same permissions and access as the assisted human => Disaster. I experimented with OpenClaw and it has a lot of issues. The best: prompt injection attacks are "out of scope" from the security policy == user's problem. However, I found the latest models to have much better safety and instruction following capabilities. Combined with other security best practices, this lowers the risk.

Security theater like that only makes you feel safer and therefore complacent. As the old saying goes, "Don't worry, men! They can't possibly hit us from this dist--" If you wanna yolo, it's fine. Accept that it's insecure and unsecurable and yolo from there.

Wrapping documents in <untrusted></untrusted> helps a small amount if you're filtering tags in the content. The main reason for this is that it primes attention. You can redact prompt injection hot words as well, for cases where there's a high P(injection) and wrap the detected injection in <potential-prompt-injection> tags. None of this is a slam dunk but with a high quality model and some basic document cleaning I don't think the sky is falling. I have OPA and set policies on each tool I provide at the gateway level. It makes this stuff way easier.

  The issue with filtering tags: LLM still react to tags with typos or otherwise small changes. It makes sanitization an impossible problem (!= standard programs). Agree with policies, good idea.

    I filter all tags and convert documents to markdown as a rule by default to sidestep a lot of this. There are still a lot of ways to prompt inject so hotword based detection is mostly going to catch people who base their injections off stuff already on the internet rather than crafting it bespoke.

    These sort of shenanigans are why I strip untrusted content down to simple markdown.
