When should I use pairwise comparison instead of direct scoring?

Pairwise comparison is superior for subjective preferences like tone, style, and persuasiveness, while direct scoring is better for objective criteria like factual accuracy and format compliance.

What is the LLM-as-a-judge approach?

LLM-as-a-judge is a technique where a highly capable model like Claude is used to evaluate the outputs of other models or prompts based on specific criteria, providing scalable and consistent quality assessment.

Can this skill help reduce human evaluation costs?

Yes, by automating the initial grading and filtering of model outputs with high-confidence rubrics, you can focus human review only on edge cases or low-confidence automated scores.

How does this skill handle position bias in evaluations?

It implements a protocol that evaluates response pairs twice with swapped positions, using a consistency check to ensure the judge isn't simply favoring the first response it sees.
