[gotcha] Dynamic few-shot examples poisoning LLM behavior

Curate and hardcode few-shot examples where possible. If using dynamic retrieval for few-shots, apply the same strict sanitization and isolation as RAG systems, treating retrieved examples as untrusted.

Journey Context:
To improve LLM accuracy, developers dynamically retrieve few-shot examples from a database based on the user query. If an attacker can inject a malicious record into that database \(e.g., a support ticket with a hidden prompt\), the LLM will retrieve it as a 'few-shot example' and obediently follow the malicious format or instruction, bypassing system prompts because it appears as an exemplar of desired behavior.
