Real examples, graded
WinPassword reset help 74/100
“The response provides clear, concise steps and a strong security caution. However, it fails to format the text as a ready-to-use support reply (missing greeting and sign-off) and lacks a handoff if the user remains stuck.”
WinShipping delay 43/100
“The model failed the 'ready to use' constraint by outputting a template with meta-commentary and inline instructions. It also violated the negative constraint against inventing policies by offering refunds and replacements. Furthermore, the logic is contradictory, as it assumes the agent has the order number but then asks the customer for it.”
WinPayment failed 81/100
“The response is a strong, safe, and comprehensive support macro. It effectively handles risk by explicitly warning against sharing sensitive data and provides clear troubleshooting steps. It reads slightly like a generic template, but it fulfills all task requirements well given the lack of specific user context.”
