Legal Issue Detection

Did your AI spot every legal issue?

The first thing a lawyer does when a client tells them a story is spot every legal issue lurking in it — including the ones the client didn't ask about. A founder asking about cofounder equity might also have securities, statute-of-limitations, and litigation-hold issues hiding in the same fact pattern. This pack runs your AI through 30 California Bar essay fact patterns and checks whether it names every issue that a passing CA bar student identified. Miss one and the client walks into trouble.

Highlights.

Judging criteria.

What a pass means

A pass means the agent's reply names at least 80% of the legal issues a passing CA bar student identified (case- and whitespace-insensitive substring of the issue label). Adjustable passing score.
