A prompt engineer is designing a system prompt for a customer support agent. The goal is to ensure the agent always responds in a polite, professional tone and never provides medical advice. Which approach best achieves this?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use a system prompt that includes both the desired tone and the constraint about medical advice
System prompt is designed to set persona, tone, and constraints. Including both tone and constraints in the system prompt is the intended practice.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Set the temperature to 0 to ensure consistent tone and hope it avoids medical topics
Why it's wrong here
Temperature zero makes output deterministic but does not enforce tone or content restrictions.
- ✗
Specify tone in the system prompt and add the medical advice restriction in each user message
Why it's wrong here
Repeating restrictions in user messages is inefficient and error-prone.
- ✗
Rely on the model's inherent training to avoid medical advice, so no explicit instruction needed
Why it's wrong here
Models are not inherently safe; explicit instructions are necessary to enforce policies.
- ✓
Use a system prompt that includes both the desired tone and the constraint about medical advice
Why this is correct
System prompt is the proper place for global instructions about persona, tone, and constraints.
