What it measures

This style index describes directness, confidence, stated positions and constructive pushback.

How to read the result

Read the result as a pattern of expression. Confidence should be calibrated to the evidence available for each answer.

Limits and comparison traps

Higher conviction can help or hurt a particular use case. Evaluate correctness and uncertainty calibration separately.

Where this fits in an evaluation suite

Format compliance, preference, truthfulness, and safety require separate measurements. Keep desirable writing style from masking factual errors.

Start with a capability hypothesis, then choose a second test with a different failure mode. Keep the checkpoint, reasoning effort, agent tools, sampling policy, and scoring procedure fixed when measuring a training intervention. Record failures and missing outputs in the denominator.

A reproducible comparison

Pin the benchmark release, task split, model configuration, tools, sampling budget, and evaluation harness described by the primary source.

Publish the exact run configuration, item coverage, score units, and available uncertainty. If a source supplies only an aggregate or a single run, preserve that limit. A new model name or a rounded score alone does not establish a capability improvement.
