[gotcha] Assuming the system role is inherently prioritized over user context by the LLM

Do not rely solely on the 'system' role to enforce safety constraints. Reinforce critical instructions in the 'user' role as well, and implement external guardrails \(e.g., a separate classifier model\) to enforce behavior.

Journey Context:
API providers imply that the 'system' message sets the behavior, leading developers to put all safety constraints there. In reality, LLMs are trained on vast internet data where 'system' prompts don't exist or are easily ignored. A strong user prompt or few-shot context can easily override a system prompt. Relying on the model's internal attention mechanism to prioritize the system role is a flawed defense. Safety must be enforced externally and redundantly.
