The README opens with

Catch spec drift on every commit. jev-spec checks your code against the requirements in your Markdown specification and fails the build when they drift apart. It asks TypeSafe AI's Jev model one focused question per requirement, gets a probability back, and compares it with a threshold you set. That makes it small enough for a pre-commit hook and strict enough for a CI gate.

Example report. The layout is what the CLI prints (timing and cost lines omitted); the probabilities are illustrative.
