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.
