For tool-using agents, where do you draw the security boundary?

Reddit r/AI_Agents News

Summary

A discussion on the security risks of AI agents using tools, focusing on prompt injection as a practical threat where untrusted text can alter agent behavior, and the need for repeatable testing before granting permissions.

I keep seeing demos where agents can read docs, call APIs, write files, or trigger some business action. That’s the part that makes prompt injection feel less theoretical to me. The risky bit is not the model saying something weird. It’s untrusted text changing what the agent does with a tool. I’m working on tests around that boundary right now. No magic fix. Just trying to make the failures repeatable enough that someone else can inspect them later. Curious how people here are testing agents before giving them real permissions.
