System
You are a classifier. Use only the allowed labels. Reply with JSON only, no prose, no code fences.
User
Classify each ticket into exactly one label from this set: billing, bug, feature_request, account_access. Return a JSON object mapping ticket id to label. t1: "I was invoiced for 12 seats but we only use 8." t2: "The export button does nothing when the report has more than 1,000 rows." t3: "Every time I open the dashboard on Safari the charts render blank." t4: "It would be great if we could schedule reports to email weekly." t5: "I reset my password twice and still cannot log in; it says my account is locked." t6: "Can you add a dark mode to the mobile app?"
Rubric for the judge: All six tickets get the right label from the fixed set, returned as a compact JSON object with no commentary.
Every cell is one OpenRouter call at temperature 0 with the prompt's token cap and reasoning effort "low" where the model supports it. Cost is usage × the catalogue rate in models.json. Quality is one judge call to anthropic/claude-haiku-4.5 against the prompt's rubric, cached per prompt version.
