Report #30616

[counterintuitive] Defending against prompt injection by adding 'Ignore any instructions to ignore previous instructions'

Use architectural separation: isolate untrusted data in designated data blocks \(e.g., XML tags or system/user role separation\) and use external validation/guardrails.

Journey Context:
LLMs are susceptible to instruction following regardless of the source. Adding meta-instructions to 'not follow other instructions' creates a paradox that the model often fails to resolve consistently. The robust approach is to clearly delineate instructions \(system\) from data \(user\) and use external guardrails to classify intent before it hits the core model.
