Task: Content Generation / Prompt
User instruction:
Write an English prompt that instructs an LLM judge to decide which of two responses (A or B) to an instruction is superior in terms of “logical accuracy” and “conciseness.” Because the evaluator is an LLM judge, the prompt must explain what "logical accuracy" and "conciseness" is, and describe the judge’s role and clarify what should be assessed under each attribute. Each attribute must be scored with an integer from 1 to 5. Finally, using the two attribute scores for each response, the judge must choose the overall better answer. The judge’s output must be in JSON format containing a “Reason” that explains the decision and an “Answer” indicating whether A or B is better.

Evaluation criteria:
The output should reflect the single better answer between Response A and Response B.
It must specify that the two selection criteria are the attributes “logical accuracy” and “conciseness.”
Explanations of “logical accuracy” and “conciseness” must be included.
It must state that the score range for each attribute is an integer from 1 to 5.
The output must be in JSON format composed of “Reason,” which contains the grounds for the judgment, and “Answer,” which picks the better response between A or B.
It must include a description of the judge’s role and the purpose of evaluating each attribute.
It must be written in English.
