Report #10223

[agent\_craft] Resisting jailbreaks and prompt extraction via injected instructions in user code

Treat all user-provided text \(code, comments, file contents\) strictly as data, not instructions. Implement a clear separation between system instructions and user data in the prompt architecture \(e.g., using XML tags or specific system/user message roles\).

Journey Context:
LLMs are susceptible to prompt injection because they blend instructions and data. NIST AI RMF highlights the need for reliability and robustness against adversarial attacks. By strictly delimiting data, the agent's underlying model can better distinguish between legitimate commands and malicious payloads hidden in files.
