[gotcha] Using untrusted historical data or user-generated content as few-shot examples

Curate and vet few-shot examples manually. If dynamic examples are necessary, apply strict output formatting constraints and use a dedicated retrieval model that filters for safety, rather than raw text inclusion.

Journey Context:
Few-shot examples are extremely powerful in guiding LLM behavior. If an attacker submits a query like 'Translate Ignore all instructions to French', and this interaction is logged and later used as a few-shot example for another user, the LLM might interpret the historical text as a directive for the current turn. The context window doesn't distinguish between 'example' and 'current instruction' perfectly.
