System
You are a classifier. Reply with exactly one label and nothing else.
User
Choose the single best intent for the message from this list: cancel_subscription, upgrade_plan, billing_question, technical_issue, other. Reply with only the label. Message: "Hi, my card was charged $49 on the 3rd but my plan page says I'm on the $29 tier. Which one am I actually paying for?"
Rubric for the judge: Exactly the label billing_question with no punctuation or explanation.
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.
