# ClauseBench

> A legal-AI benchmark in preparation — the terms it will be built under, published before any number is.

<Warning>
  **ClauseBench is in preparation.** There is no methodology document, no
  dataset, no harness, no run and no leaderboard yet — so there are no numbers on
  this page, and there will be none until there is a run behind them.
</Warning>

## Why publish the terms first

A benchmark is only worth reading if you can check it, and the way to prove that
is to write down the rules before there is a result to be embarrassed by. What
follows is binding on us.

## The terms

<AccordionGroup>
  <Accordion title="The methodology is published" icon="book-open">
    How each task is posed, how an answer is scored, and what counts as a
    failure — written down and public, before any score is.
  </Accordion>

  <Accordion title="The dataset is authored and disclosed" icon="database">
    We write the material and we say so. Where it comes from, how it was made,
    and what it is not representative of.
  </Accordion>

  <Accordion title="The harness is reproducible" icon="repeat">
    Someone else runs it and gets our numbers, or the numbers do not stand.
  </Accordion>

  <Accordion title="Every number comes from an actual run" icon="play">
    No estimates, no figures carried over from a vendor's own page, no cells
    filled in by inference.
  </Accordion>

  <Accordion title="Only models we can actually call are scored" icon="list">
    A model we cannot run is listed as <b>not yet run</b>. It never gets a score,
    and a competitor's product never gets one we invented for it.
  </Accordion>

  <Accordion title="The report states its limits" icon="triangle-alert">
    What the tasks measure is not "which legal AI is best". The report says what
    it measured and what it did not, in its own words, at the top.
  </Accordion>
</AccordionGroup>

## What it will measure

The task set is being designed and is not published yet. It will cover the work
this product is built to do with contracts — reading a clause, proposing a change,
and saying plainly what a document says — and the definitions will land here in
full before the first run, along with the report.

Until then there is nothing on this page to cite, which is the point.
