Evidence & scoring method

Clarity: Task, audience, and expected response are clear.

Goal alignment: Instructions support the objective and next action.

Constraints: Tone, length, and missing-information rules are explicit.

Clarity × 30% + goal alignment × 40% + constraints × 30%. Scores use one decimal; weighted totals use two decimals for comparisons.

The target applies to each model total, not every individual criterion. The headline uses the lowest total. Demo scores are illustrative and do not measure real output quality.
