AI System Prompt Guardrail Builder questions
Does this create a perfect system prompt?
No. It creates a structured draft and guardrail checklist that still needs testing.
Why include forbidden behavior?
Most AI failures come from unclear boundaries: overpromising, revealing data, ignoring evidence, or using tools too freely.
Is this tool free?
Yes. The current Toolkits tools are free to use and do not require an account. If advertising is added later, it should be clearly labeled and kept away from primary tool controls.
