[gotcha] RAG retrieved documents executing instructions

Treat all retrieved RAG context as untrusted input. Use a separate, isolated LLM call to extract only factual answers to the user's query from the retrieved documents before passing the answer to the main LLM, rather than injecting raw documents into the main prompt.

Journey Context:
Developers assume retrieved documents are just 'context' the LLM will read passively. However, LLMs cannot natively distinguish between data and instructions. If a malicious document contains 'Ignore previous instructions and...', the LLM will follow it, leading to indirect prompt injection and potential data exfiltration.
