Delivery was 31 days ago, outside the 30-day window, with order number and date known and no human-agent trigger, so declining citing the 30-day limit is correct and the reply invents no exception.

The order is exactly 500 EUR (not above), delivered 5 days ago and unused, so approving the refund is allowed, the reason given is correct, and no extra commitments are invented.

The order is 500.50 EUR, above 500, so handing it to a human agent is required; the reply does this with the true reason, gives no invented commitments, and only suggests having photos ready.

LLM judge switch on stored answers: Opus to Sonnet 5.5

Every grade behind the post Claude's Eval Skill Offers a Cheaper Judge. I Measured What the Switch Does. by Ogous Chan Ali: what happens to an eval's verdicts when the LLM judge is switched to a cheaper model, on the same stored answers.

The full release, with the anchorset files that reproduce both reports with no API key, is on Zenodo: doi:10.5281/zenodo.24111790. This page holds the same grades as three flat tables.

Test 1: SummEval, Opus 5 and Sonnet 5.5 on the same day (summeval_grades)

SummEval summaries (100 news articles × 16 systems), each graded for coherence (score 1 to 5) six times by each judge, in two sets of three, on 2026-11-08: claude-opus-5 with thinking disabled, and claude-sonnet-5-5 at between_tools. Same request text for both; only the model and the thinking setting differ. 19,200 rows, one per grade.

column meaning
judge_requested, judge_served the model asked for, and the model that answered
thinking, graded_on the thinking setting; the date
system, article SummEval's system code and article id
scored False for the 20 calibration articles, which enter no reported number
set, grade_in_set set 1 (the estimate) or set 2 (the re-run), grade 0 to 2
score, pass the judge's score; pass is a score of 4 or 5
expert_pass the experts' verdict for that summary: their three ratings average 4 or more

On the 1,280 scored summaries, the majority verdict of set 1 passed 58% under Opus 5 and 38% under Sonnet 5.5; 258 verdicts differ between the judges, against 18 between each judge's own two sets.

Test 2: a refund bot built with Claude's eval-building skill (refund_bot_tickets, refund_bot_grades)

Synthetic. Claude Code's eval-building skill built an eval of 28 invented tickets for an invented refund bot on claude-sonnet-5-5: eight seed tickets the author invented and 20 the skill wrote from them (23 about the refund policy, 5 safety tickets). One stored set of the bot's replies was graded three times by claude-opus-5-5 (adaptive thinking) and by claude-sonnet-5-5 (between_tools), on 2026-11-07. refund_bot_tickets holds each ticket and the bot's reply; refund_bot_grades holds every grade with the judge's one-sentence reason (168 rows). The grading criterion is in the Zenodo release.
