Why Rubric

A red pen for your prompts.

Rubric is opinionated by design. It scores how you actually communicate with the model, not whether you got a good answer. The goal is to get better at prompting, not to feel good about every session.

Strict 0–100 rubric

Six weighted dimensions: specificity, context, structure, iteration, scope, meta-prompting. Calibrated so a competent median lands around 50, not 80.

FAQ

Common questions, plain answers.

The short version of the methodology and the deal on pricing.

No. The scoring model only ever sees your turns. Assistant text is summarized locally in your browser into three primitives (length, whether it contained a code block, whether it contained an error), and only those summaries leave your device. The full assistant text never goes to the analyzer. There's a methodology page with the wire-level details and the tests that verify it.
