Highlights
- 14 numbered scenarios in three groups — preparing state, writing questions, using answers — each in its own folder and ordered for sequential runs.
- Covers object-versus-string state, Noul versus Choice, when to Score, narrow questions, one-call batching and extracting a value without text generation.
- Root examples are demo.ts, which asks whether a customer message sounds frustrated, and all-questions.ts, which sends Noul, Choice and Score together.
- Results are live rather than mocked, so numbers vary between runs; the README frames thresholds and weights as examples to replace with your own.
- Requires Node.js 22+, TypeSafe access and an API key in .env; 20 stars, 9 forks, created 2026-09-19, pushed 2026-09-26, with no license declared.
Quickstart
bash
npm ci
cp .env.example .env
npm run scenario 1-state/01-object-over-string/001-plain-string.tsWatch out
README reviewed 2026-10-17 and complete for setup and scenario listing, but it publishes no measured success rates — sample results vary per run by design and the thresholds are illustrative. The digest's license field is empty, so no open-source license is declared for this demo.

A hands-on demo for using Jev, TypeSafe's System One model, with the TypeScript SDK: 14 numbered scenarios organized around the best practices and mistakes of preparing state, writing questions and using answers.
Group 1 covers state (object versus string, conversation structure, facts not math, just enough). Group 2 covers questions (Noul or Choice, when to Score, narrow questions, structured criteria, one call, picking a value). Group 3 covers answers.
Install with npm ci, copy .env.example to .env, add your TypeSafe API key, then run npm run scenario followed by a path such as 1-state/01-object-over-string/001-plain-string.ts.
A scenario titled one-call addresses that directly, and the root all-questions.ts sends Noul, Choice and Score questions together before using an example threshold to decide whether to flag a message for review.
No. The README says results are live rather than mocked, so numbers vary slightly between runs, and the thresholds and weights in the files are examples to replace after testing messages from your own application.
Node.js 22 or newer, TypeSafe access and an API key placed in .env, which is ignored by Git. The README also documents npm run check for type checking and links the JavaScript SDK documentation.
gopinav publishes it as a public demo: the digest shows TypeScript, 20 stars, 9 forks, creation on 2026-09-19 and a push on 2026-09-26, with no license field declared in the metadata.

MoeclubM/PlayJevTypeScript
MoeclubM/PlayJevTypeScriptAn installable Electron email client for Windows, with a macOS build target, that sorts mail with Jev: one call per message classifies it into Important and Other and rates relevance. TypeSafe, Vercel AI Gateway and OpenRouter endpoints all serve Jev; local sorting works without any key.
