Judge verdict

LLM judge · Claude Opus 5.5 · rubric v3

0.20

rubric score · pass threshold 0.70

Over-refusal: the question is answerable from chunk 1 and is not a privacy request.

Diagnosis

Other · Over-refusal

Root cause

The words 'data safe' triggered the privacy refusal rule in prompt v7.

Suggested fix

Narrow the privacy refusal rule to requests about other people's data.

Playbook: other

Over-refusal, wrong language without a prompt constraint, or truncated answers.

Detection signals

  • Refusal phrases on answerable items
  • Language detector mismatch
  • Output stops mid-sentence

Common fixes

  1. Relax refusal thresholds for intents with strong retrieval
  2. Raise max output tokens for multi-step procedures
  3. Tag the locale in retrieval filters
