Before you dive in
What you’ll find in the original
- Use Jev for classification, routing, scoring, ranking, and confidence—not for the generative work performed by Claude or another LLM.
- Define a bounded Choice criterion separately from confidence-style questions so each answer has a clear meaning.
- Treat Score as an ordered scale and Choice as an unordered option set; they are not interchangeable outputs.
Worth knowingThe video is an introductory runnable example and repeats launch speed claims without independently benchmarking them.
