[gotcha] Dynamic Few-Shot Example Poisoning

Curate few-shot examples statically or from highly trusted sources. If using dynamic examples, apply strict moderation and anomaly detection before they are injected into the prompt.

Journey Context:
Dynamic few-shot prompting improves accuracy by fetching examples from a database. However, if an attacker can submit inputs that get saved and later retrieved as few-shot demonstrations, they can permanently alter the model's behavior for other users \(e.g., teaching it to output malicious links\). Static examples reduce adaptability, but the few-shot context is a high-privilege attack surface that can compromise all subsequent users.
