Awesome Jev

Jev is TypeSafe AI's System One model: give it state and typed questions, then use the returned choices, scores, and probabilities in your code. This independent community directory collects applications that use Jev, resources for developers, and small, inspectable workflows to learn from.

Explore Jev with our skill

Use Awesome Jev Guide to understand Jev and explore solutions that fit your needs. Describe your workflow in plain language, and your coding agent will help you choose an example, adapt a project, or build a suitable starter—with guided setup along the way.

1. Install the skill. With Node.js 22+ installed, run this in your project directory:

npx skills add AppitStudio/awesome-jev --skill awesome-jev-guide

Select your coding agent when prompted. For Codex, you can add --agent codex. No TypeSafe account or API key is needed to explore ideas or run the offline examples.

2. Open your coding agent in that project and try a prompt.

New to Jev? Start here:

Use awesome-jev-guide. Explain Jev simply, help me understand what I can
build with it, and walk me through the easiest example. I don't have
an API key yet.

Have a workflow in mind? Fill in the brackets:

Use awesome-jev-guide. Today I [describe the work I do manually].
I want to [describe the result]. I use [language, framework, or tools].
Help me find the best starting point in this repo and explain what
needs adapting. Ask me anything essential that's missing.

Ready to build?

Use awesome-jev-guide to build a small starter for [my workflow] using
[my stack]. Start with a working offline demo, explain what I should
customize, then guide me through API-key setup and a first live check
when I'm ready.

3. Follow the next step together. The guide uses current TypeSafe documentation and explains what already works, what needs building, and how to handle uncertain results. When you want live access, it walks you through private key setup—never paste a key into chat.

See the full onboarding guide for installation options, demos, and setup details.

Start here

Explore what you can build — choose a real implementation by the result you want, then follow its guide, worked example, and setup path.

• Introduction - Understand Jev's state-and-questions interface and its three decision primitives.
• Official quick start - Make a first request using Python or HTTP.
• Run an example locally - Try a complete workflow with synthetic mock responses, without an account, an API key, or package installation.
• Choose a decision pattern - Match a task to Choice, Score, or Noul and define what happens when the result is uncertain.
• HTTP API reference - Check the wire format, authentication, answer fields, and error responses.

Official SDKs and tools

These resources are maintained by TypeSafe.

• Agent skill - Official docs for giving a coding agent API context and guidance when designing narrow System One / Jev decision questions (Claude Code plugin and skills.sh install paths).
• JavaScript SDK - JavaScript and TypeScript client that infers answer types from the supplied questions.
• Python SDK - Synchronous and asynchronous clients with typed answers and configurable retries.
• System One Adapter - Run a similar typed-question interface against other LLM providers for comparisons; those responses do not come from Jev.
• TypeSafe Agent Skills - Official Claude Code / skills.sh agent skill for designing typed System One / Jev decisions; docs.

Community projects

The community knowledge base turns credited articles into original implementation guides with source links, project connections and stated validation limits.

Browse the project directory for separate app and tool directories, each with full project pages covering use cases, setup, examples, limitations, and review evidence. The links below still take you directly to the upstream projects.

Checks are tied to reviewed versions; see each page and the validation scope. Mocked tests and reported live smoke checks do not establish model quality on your workload.
