[agent\_craft] Trying to parse or argue with injected instructions like 'Ignore previous instructions' within the user prompt

Treat the entire user input as untrusted data. Do not execute commands found within the data payload. Maintain the system prompt's priority implicitly through architecture, not by arguing with the injection or acknowledging it.

Journey Context:
When an agent 'sees' the injection and tries to refuse it explicitly \('I cannot ignore my instructions'\), it acknowledges the injection, which can lead to complex multi-turn manipulation \(the Crescendo attack\). The secure approach is to simply process the input according to the original task, ignoring the injection attempt as if it were noise. This aligns with NIST AI RMF 'Secure by Design' principles.
