This answers:Felt off
Use this field for specific notes. Good:Semantic confidence sliders
The five scoring dimensions use stepped 1–10 semantic sliders. The slider is not decoration. It is part of the evaluation interface. A low score should feel like concern. A middle score should feel mixed or uncertain. A high score should feel confident. This reduces the amount of mental translation required from reviewers. The app may show suggested 1–10 values before the reviewer chooses a score. A visible suggestion is not the saved score until the reviewer accepts or overrides the review and saves.Human Guidance Evaluation
Eval Labs also captures 1–5 Human Guidance Evaluation scores:tone, calming, naturalness, trust, usefulness, cognitiveUnderstanding, actionability, and authenticity.
