What makes a good system prompt?
Clear role definition
"You are a [specific role] that helps [specific audience] with [specific task]." Sets the persona anchor for all responses.
Specific, non-conflicting instructions
Instructions should not contradict each other. Ambiguity causes inconsistent behavior. Use explicit "You may" and "You must not" lists.
Safety guardrails
At least one "do not" or "never" rule prevents unintended outputs. Critical for production deployments.
Output format specified
"Respond in plain text", "Return a numbered list", "Format as JSON". Without this, models choose their own format.
Fallback behavior defined
What should the agent say when it cannot answer? Define this explicitly to avoid hallucination at capability edges.
Audience and context
Who is the agent serving? What system is it part of? Context helps the model calibrate detail level and tone.
