TL;DR

alexbejan/jevkit showed up as Jev / System One related work: Verified TypeSafe Jev / System One work — Jev or System One is the core idea.

The author describes it as: “TypeSafe Jev as a bounded judgement layer for computer use: verify, pick, classify over Cua Driver and phone-harness” That is their claim, not a bench this site ran.

Who it’s for

• Computer-use and browser-loop authors who already have text state from OCR or the a11y tree
• Anyone who needs the unofficial line: jev.pro does not issue keys and is not TypeSafe

What’s inside

Top-level entries on GitHub at generation time: .gitignore, README.md, SETUP-PROMPT.md, evals, pyproject.toml, shim, skills, src, tests. Read those before you trust a one-line install.

How to use

1. Clone and follow the author’s Python toolchain. Do not invent a package name.

git clone https://github.com/alexbejan/jevkit.git
cd jevkit

2. If the project calls hosted Jev, you still need a TypeSafe console key or a documented gateway.
3. Send a complete state and typed questions. Code owns control flow after the probabilities.

Hosted Jev still looks like a function call — wrapper or not:

{
  model: "jev-1.13.0",
  state: { source: "alexbejan/jevkit", brief: "..." },
  questions: {
    gate: { type: "noul", instructions: "Should we act on this state?" },
    route: { type: "choice", instructions: "Pick one next system.", criteria: ["code", "review", "human"] },
  },
}

Try this

One typed action per frame

Using alexbejan/jevkit, send Jev a text brief of the current screen and ask for Choice{click, type, wait, give_up}. Do not ask Jev for coordinates or screenshots — it is text-only.

Schema-safe ≠ correct

On a case alexbejan/jevkit gets wrong, write down the schema-legal answer it returned and the human label. Do not “fix” it by asking Jev to generate an explanation.

FAQ

Does this replace the TypeSafe SDK?

Only if the author implemented a full client. Most harnesses still call the vendor SDK or raw HTTP.

Are the star chips live?

Star, fork, and watcher chips refresh from the public GitHub API via a scheduled job. The prose on this page is editorial.
