Pass/Fail Beats 1-5 Ratings for Agent Regression Tests, Argues Practitioner
intellectronica · x · 2026-10-31
Pauliusztin argues AI agent regression tests should use pass/fail verdicts instead of scores: asking an LLM judge to rate 1-5 introduces unnecessary ambiguity, and a regression check needs a clear answer on whether the agent met the requirement.
intellectronica agrees and sharpens the point: humans are bad at scoring on a scale and LLMs are even worse — the right approach is pass/fail judgments, run many times and aggregated.
