Scoring the quality of legal drafting.

LexGrade is an open instrument for grading legal motions. The principles, the weights, and the ethics gate are published in full, in human and machine-readable form.

Why an ethics gate? In one 2024 study, leading language models hallucinated in 58–88% of their answers to verifiable questions about federal court cases (Dahl et al., Large Legal Fictions). The Standard treats a single fabricated citation as an automatic −20, because candor toward the court is where grading has to start.
