[agent\_craft] Agent bypasses safety constraints like 'do not modify files outside /tmp' when they are buried in long system prompts

Use the 'instruction hierarchy' pattern: place unbreakable constraints in the system prompt with explicit 'HIGH PRIORITY' markers, and repeat them in the user message wrapper; ensure the final user message always reiterates active constraints to defeat recency bias.

Journey Context:
Standard system prompts often list constraints at the top, but as the conversation grows or tools are described, the model's attention shifts to recent tokens. OpenAI's 'Instruction Hierarchy' research \(2024\) formally proved that models can be fine-tuned to respect hierarchical constraints where system > user > tool, but even in base models, explicitly marking constraints with delimiters like '=== CRITICAL CONSTRAINT ===' and repeating them in the user turn significantly reduces jailbreaks and accidental violations. The common failure mode is assuming that saying it once in the system prompt is sufficient for a 10-turn conversation. The fix combines static system-level rules with dynamic user-level reminders on every turn that involves risky actions \(file writes, network calls\).
