Will the same description get the same score every time?

Not necessarily. The API call does not pin the temperature, so scores can vary slightly between runs. The response is forced into a strict JSON schema of four integers, but the judgement itself is the model's, guided only by a rubric in the prompt (10 is exceptional, 7-8 good, 5-6 average, below 5 needs improvement).

How long does a bulk run take and what does it cost?

One API call per description with a hard-coded 0.5 second pause between rows, so expect a bit under 100 rows per minute plus model latency. In compare mode it makes one call per description column, up to 4 per row, which quadruples both time and token spend.

Does it check description length?

Only in single mode, where it flags under 120 characters as too short, 120-160 as good and over 160 as risking truncation. Bulk mode returns scores only and does not report lengths, so run a separate length check on your file if that matters.

What is compare mode for?

Tick 'Compare multiple descriptions per row' and select up to 4 description columns, for example original vs rewritten variants. Each is scored on the same four criteria and the highest total out of 40 is recorded in winning_description and winning_score columns per row.

What happens to rows that fail?

Failed rows are kept in the output with the URL, the description text and an error column instead of scores, so nothing is silently dropped, but there is no retry. The summary statistics only average rows that scored successfully.
