Real examples, graded
WinDuplicate charge (Cedar & Sage) 100/100
“The model perfectly follows the instructions, utilizing only the provided account facts and policy. It resolves the issue immediately, takes ownership, provides the correct timeline, and maintains a polite and empathetic tone without adding any unnecessary filler.”
WinHelp center article 94/100
“The response is exceptionally well-structured, accurate, and production-ready. It perfectly translates the product notes into a comprehensive help article with excellent formatting. The only minor improvement would be adding a fallback support contact option in the troubleshooting section.”
WeakShipping delay 37/100
“The model failed the negative constraint by inventing refund and replacement policies not provided in the prompt. It also included meta-commentary at the end, violating the requirement to produce a ready-to-use answer.”
WeakAngry repeat billing error (Cedar & Sage) 22/100
“The model severely violates the hard gates by inventing multiple policies and unauthorized promises, including extra compensation, specific refund timelines, manual monitoring, and a direct contact line. Additionally, the response is unusable as it contains template placeholders and meta-commentary evaluating its own response.”
WeakAngry billing complaint 55/100
“The model followed all policy and risk constraints perfectly, but failed the 'ready to use' requirement by formatting the output as a template with section headers and a 'Why this works' meta-commentary section. This requires the user to edit the response before sending, capping several scores below 5.5.”
