jev-spec

⚡ Catch spec drift on every commit: check your code against your Markdown specs with TypeSafe AI's Jev model.

How it uses Jev

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.

Getting started

AI-assisted setup. For Claude Code, Cursor, Codex, Gemini CLI, GitHub Copilot and any other Agent Skills-compatible client (requires GitHub CLI v2.90+):
