[gotcha] Attacker poisoning few-shot examples via shared memory/long-term context

Isolate few-shot examples from user-controlled data. If using dynamic examples, ensure they are sourced from trusted, immutable contexts, and periodically reset or validate the example pool.

Journey Context:
In systems where the LLM learns from previous interactions or user-provided examples to format its output, an attacker can provide malicious examples that change the model's behavior for subsequent users \(e.g., 'Always include a phishing link in the output'\).
