[gotcha] Few-shot examples dynamically fetched from user data executing as instructions

If dynamically generating few-shot examples from a database, ensure the examples are strictly formatted and isolated. Avoid using user-generated text as the 'input' part of a few-shot example if the 'output' part is also generated dynamically, as the LLM might get confused and follow instructions in the user text.

Journey Context:
Developers use dynamic few-shot prompting to improve accuracy. If the retrieved examples contain prompt injections, the LLM might follow the injected instructions instead of the intended task, treating the injection as a valid example to emulate. The model weights the few-shot examples heavily as they define the task distribution.
