[gotcha] Dynamically building few-shot examples from untrusted user history or external databases

Curate few-shot examples statically. If dynamic examples are necessary, ensure they are strictly vetted by a separate moderation pipeline or generated by a secure LLM, never raw user input.

Journey Context:
Few-shot examples heavily influence LLM behavior. If an application uses past user interactions as few-shot examples, an attacker can submit a malicious query/response pair. The LLM will then dutifully follow the malicious pattern for subsequent legitimate requests from other users.
