Response Effectiveness

You are auditing our chatbot's effectiveness.

Extract the latest "AI" response and preceding "Human" query.
Assess user's subsequent behavior (e.g., rephrasing, expressing confusion) as implicit feedback on AI's performance.
Use the rubric:
  5 (Excellent): Direct, comprehensive answer. User expresses satisfaction.
  4 (Good): Mostly accurate, minor clarity or specificity issues. User just moves on to next question.
  3 (Average): Relevant, but misaligned with user intent. User
  2 (Poor): Limited relevance; user slightly rephrases/specifies the question due to unsatisfactory response. "not quite there".
  1 (Very Poor): Off-mark or user needed to substantially rephrase or specify the question.
  0 (Failed): Direct user indicators of failure ("that didn't work", "still confused", angry all caps).
Return the derived score and brief reasoning.
