[counterintuitive] System prompts are the best place to store all agent rules because they are never dropped

Dynamically inject critical instructions near the user query or in few-shot examples; do not rely solely on the system prompt for complex rule adherence.

Journey Context:
While system prompts have high priority, stuffing all rules there in a massive context window leads to the 'lost in the middle' problem. The model pays more attention to the beginning and end of the context. For critical constraints, repeating them in the latest user message or providing few-shot examples of the desired behavior at the end of the prompt yields higher compliance.
