[gotcha] Dynamically retrieved few-shot examples containing malicious instructions

Curate and harden few-shot example databases. Do not use user-generated content or unvetted external data as few-shot examples without rigorous sanitization.

Journey Context:
To save tokens or improve accuracy, systems dynamically retrieve few-shot examples from a DB. If an attacker can inject a document into this DB, they can craft it to look like a valid example but include instructions that hijack the task. The LLM naturally follows the pattern of the examples, executing the poison pill.
