krw82/jev-playwright-mcpTypeScript

forma-system1-experiment

An experimental design harness that splits the work: Jev picks layout, blocks, colours and typography from a prebuilt catalog in about a second, while an optional small LLM fills typed text slots a few seconds later.

LamplighterPaul/forma-system1-experimentTypeScript

jev-cli

A thin Node CLI over the System One API: pass a state string and a question map, get typed answers with probabilities, confidence, latency and token counts back as JSON, one at a time or through a batched worker pool.

typesafe-3d-chess

A 3D chess board where Jev plays: AI versus AI by default, or take either side yourself, with several difficulty levels. The repository README is three lines long and documents nothing beyond that.

Jev Demos & Experiments#community#jevbest#catalog-import

Community

malDuffin/typesafe-3d-chessTypeScript

jev-lab

A small Node.js TypeScript CLI for trying Jev on synthetic support text: one urgency question, three questions in a single request, or a latency comparison. No web server and no UI.

Menny1337/jev-labTypeScript

magic-jev-ball

A Magic 8 Ball that picks with Jev instead of at random. Hold, shake, release, and Jev chooses from the twenty classic answers and returns a probability for each one, shown under the ball.

mikecann/magic-jev-ballTypeScript

check-risk

A CLI and GitHub Action that turns a Git change into an explainable risk score, required checks and reviewer groups, where deterministic rules and Jev's semantic judgements both trace back to a named rule.

Jev Agents & MCP#community#jevbest#catalog-import

Community

moezubair/check-riskTypeScript

jev-dev

macOS demo that runs one utterance through both TypeSafe jev and an LLM judge, accumulates each verdict as a separate affectus emotional state, and shows the split as Plutchik petals, per-axis deltas and two replies generated from a single fixed persona.

Jev Demos & Experiments#community#jevbest#catalog-import

n-yokomachi/jev-devTypeScript

jev-data-questions

Vite app that turns a small CSV into a presentation-ready dashboard by profiling every column, choosing the charts that fit the data and writing a headline per chart, with an optional Jev pass that reads each row for what the columns cannot answer on their own. The built-in demos run entirely in the browser.

narulaskaran/jev-data-questionsTypeScript

cartshield

A repository whose README is a title and one sentence: SMB checkout fraud disposition with TypeSafe Jev. There is no install step, no request schema, no decision labels and no threshold list in the documentation, so the stated use case is the only claim available.

Jev Demos & Experiments#community#jevbest#catalog-import

Community

ndolinschi/cartshieldTypeScript

harnessjudge

Paste a trace of an agent step, get one of four dispositions back: ok, retry, escalate or stop. Aimed at agent builders putting a supervision step around an agent loop, with the judging powered by TypeSafe Jev and a two-command setup.

Jev Demos & Experiments#community#jevbest#catalog-import

Community

ndolinschi/harnessjudgeTypeScript

hiresignal

HireSignal is a resume first-pass scoring demo running on TypeSafe Jev. The whole README is a single sentence, so the interface, the scoring rubric, the question shape and the setup steps are all undocumented.

Community

ndolinschi/hiresignalTypeScript

jevplay

JevPlay is a playground for TypeSafe Jev: a freeform state block plus a builder for custom Choice, Score and Noul questions, showing live probability distributions as you write them. Setup is npm i and npm run dev.

ndolinschi/lanebreakTypeScript

mcpmatch

McpMatch takes a free-text user goal and matches it against a catalog of MCP servers or capabilities using TypeSafe Jev, with a two-stage path for large catalogs. Runs with npm i and npm run dev.

Community

ndolinschi/mcpmatchTypeScript

pulselane

PulseLane models clinic triage decisions through TypeSafe Jev on System One. An optional TYPESAFE_API_KEY in .env.local switches it from bundled demo heuristics to real model calls; without a key the heuristics return the same answer shape so the UI still runs.

Jev Demos & Experiments#community#jevbest#catalog-import

ndolinschi/pulselaneTypeScript

spendbrake

SpendBrake turns a budget plus a plan into one of three calls — continue, downgrade_model or stop — and renders the cost against value as a dashboard, with the decision made by TypeSafe Jev.

Jev Demos & Experiments#community#jevbest#catalog-import

ndolinschi/spendbrakeTypeScript

swarmrouter

SwarmRouter picks which agent or skill should handle a task and returns a confidence with the pick, drawn as a visual swarm map, with the choice made by TypeSafe Jev. Five handler types are named in the README.

Jev Demos & Experiments#community#jevbest#catalog-import

Community

trustgate

TrustGate is described in one line as an indie media trust and safety gate powered by TypeSafe Jev. The README carries no further detail: no commands, no inputs, no verdict set, and no setup instructions.

beat-jev

Browser penalty shootout where you take turns shooting and keeping goal: one Render Workflows task owns the match, Render Postgres holds the score, and TypeScript and Python examples share the same 3D frontend and rules.

ojusave/beat-jevTypeScript

openclaw-typesafe-ai

An OpenClaw plugin that registers a single optional tool, typesafe_decide, forwarding caller-supplied text or JSON state plus typed noul, choice and score questions to the System One endpoint, with jev-latest as the default model.

casse-brique-typesafe

A browser brick breaker on Next.js 16 and React 19 where you can hand the paddle to a Jev pilot: the server computes the ball's path and the model picks one of 16 zones. The in-game interface is in French.

Para-FR/casse-brique-typesafeTypeScript

jev-calculator

A calculator that lets Jev produce the digits: every step offers the same 13 options, a Cloudflare Worker forwards one System One choice request, and the page renders the per-step probability grid instead of a verified answer.

draftpulse

A local React and Express editor that scores an X draft across six dimensions, from hook strength to a slop penalty, by asking Jev several narrow rubric questions in one structured call, with a deterministic fallback when no key is set.

agent-gate-loop

A GitHub Action that turns a labelled issue into a pull request, with a four-part gate before a human sees it: path and test guards, your own check commands, a read-only Claude reviewer, and Jev checking each finding plus whether the change does what the issue asked.

Ripwords/agent-gate-loopTypeScript

JevArena

A Next.js spectator app where two independent Jev agents play Snake against each other, each spectator page running its own match. Jev is reached only through Vercel AI Gateway, and an empty key gives you a labelled demo-policy match instead.

pong-jev

Atari Pong where Jev answers one question per frame - which way should the paddle move, up, down or stay - while all arithmetic stays in code and the model is sent five short phrases. Includes a local court to duel it on.

scam-shield

Checks a text message for scam signals and turns them into an explainable verdict: code extracts link and sender signals, one parallel Jev call answers eleven typed questions, and a pure policy function weights them into a risk score.

omp-jevens-classifier

OMP plugin that judges bash commands and process-spawning eval payloads with Jev before they run, adding a real permission prompt in yolo mode while leaving your existing deny, prompt and narrow allow rules untouched.

jev-acp

ACP stdio agent that evaluates explicit Choice, Score and Noul questions as typed Jev answers inside any Agent Client Protocol client or IDE, driven by a task picker rather than free-form chat.
