Real examples, graded
WinMulti-issue ticket 85/100
“The response perfectly executes the multi-issue ticket scenario, separating the concerns clearly and providing a highly organized summary table. It avoids inventing facts while maintaining a professional tone and safe risk handling (e.g., asking only for the last 4 digits of the card). It is as specific as possible given the lack of concrete customer details in the prompt.”
WinChurn rescue 95/100
“The response is exceptionally well-crafted, weaving the provided facts naturally into an empathetic and professional churn rescue email. It follows all constraints perfectly and demonstrates expert-level customer success writing. A very minor improvement would be including a clear placeholder for the checklist link or attachment.”
WinAngry billing complaint 95/100
“The response is excellent, production-ready, and hits every constraint perfectly. It de-escalates effectively, asks for the exact required information while proactively preventing a security risk (asking not to send the full card number), sets the correct timeline expectation, and avoids promising a refund.”
