4GitHub stars
A research agent where GPT picks what to look for and Jev judges many document regions in one call, so the code can hand back verbatim passages for verification.
Jev Agents & MCP#community#jevbest#catalog-import
1GitHub stars
A small Next.js demo that sends the same input to GPT and Jev side by side, showing generative text next to three fixed Noul probabilities.
Jev Demos & Experiments#community#jevbest#catalog-import
2GitHub stars
A directory of projects actually shipped with Jev, filtered by what each one replaces, whether it was benchmarked, and whether there is code to copy.
Jev Guides & Articles#community#jevbest#catalog-import
1GitHub stars
A decision board that sends one System One request describing eleven stream ideas, then lets code gate and weight Jev's answers into a single pick for what to build next.
Jev Demos & Experiments#community#jevbest#catalog-import
2GitHub stars
A Chrome extension that runs title and abstract screening for systematic reviews inside a shared Google Sheets project, with Jev offered beside Gemini and OpenRouter as the judging model.
Jev Tools & CLIs#community#jevbest#catalog-import
1GitHub stars
A Pi extension that sends each new unit of work to a Jev client as a paid classification request and routes it to one of four configured Pi models, failing open to your baseline.
Jev Agents & MCP#community#jevbest#catalog-import
2GitHub stars
An MCP server with two tools for agent memory: record writes facts into a per-project ledger as they happen, and recall scores each one against the task you are starting and hands back only what matters.
Jev Practices & Patterns#community#awesomejev#catalog-import
2GitHub stars
Plugin for Claude Code, the Claude desktop app and Codex that has Jev read the task, then ranks live OpenRouter models by benchmark quality, price, speed and reasoning effort, returning a pick plus cheaper and faster alternatives with the exact command to switch.
Jev Agents & MCP#community#awesomejev#catalog-import
2GitHub stars
PreToolUse hook for Claude Code and Codex that puts a shell-aware rules engine and Jev in front of every tool call, returning allow, ask or block per command and logging the reason and latency behind each decision.
Jev Agents & MCP#community#awesomejev#catalog-import
2GitHub stars
Chrome extension that puts a Magic 8 Ball on GitHub pull requests: nine signals from the GitHub API go to a small server, Jev picks one of four verdicts, and the ball answers with a phrase plus its reasoning. It never approves, comments or reads code.
Jev Agents & MCP#community#awesomejev#catalog-import
1GitHub stars
Chinese-first Astro documentation site for Jev, covering the Choice, Noul and Score primitives plus intent routing, confidence routing, composite scoring and fan-out patterns, with an eight-language build and a cron pipeline where Jev gates each release.
Jev Demos & Experiments#community#awesomejev#catalog-import
1GitHub stars
Chicago traffic simulator where Jev sets citywide signal policy and two deterministic baselines replay the identical scenario: one car crosses the city while Fixed and Adaptive run headlessly against the same spawn list, seed and incident script.
Jev Demos & Experiments#community#awesomejev#catalog-import
4GitHub stars
TypeScript router that spends one Jev call deciding how an agent turn should run — model tier, effort budget, which tools are on offer and which skill applies — then your own harness runs the turn on whatever provider it already talks to.
Jev Repos & SDKs#community#awesomejev#catalog-import
1GitHub stars
Six browser demos of Jev's three primitives, each running the same judgment past Gemini or Claude for a side-by-side, with visitors pasting their own keys into localStorage instead of sharing a server-side key.
Jev Demos & Experiments#community#awesomejev#catalog-import
A reproducible 100-case demo that runs TypeSafe's Jev decision model against OpenAI's Terra and Anthropic's Opus on identical synthetic security evidence, then renders the recorded JSON to a static dashboard with no credentials in the browser.
Jev Practices & Patterns#community#awesomejev#catalog-import
1GitHub stars
A TypeScript library that treats typed semantic judgments as React hooks or plain server programs: pass one judgment's result into the next and the runtime works out the dependency, waits for fresh answers and batches compatible questions.
Jev Demos & Experiments#community#awesomejev#catalog-import
1GitHub stars
A Next.js Snake game where every move is a live System One Choice call: run it on Jev, on the wire-compatible Drex, or send the same state to both in parallel and watch the probabilities side by side.
Jev Demos & Experiments#community#awesomejev#catalog-import
1GitHub stars
An independent benchmark asking whether Jev can replace an LLM reranker, run over natural-language search across all 6,245 YC companies, plus the live search app it measures: Jev routes the query, BM25 and embeddings retrieve, Jev reranks.
Jev Practices & Patterns#community#awesomejev#catalog-import
1GitHub stars
Spanish-language demo running Jev over Spain's official gazette (BOE) daily. One call per disposition scores relevance 0-3, probes 13 policy categories with Noul, and picks the paragraph explaining the change, so the summary is selected rather than written. Astro on GitHub Pages, JSON data, no login.
Jev Demos & Experiments#community#awesomejev#catalog-import
1GitHub stars
TypeScript runtime that keeps Jev's probabilities out of the decision path. YAML policies declare preconditions, typed questions and ordered rules; it returns a decision plus an audit trace, records fingerprinted signals as JSONL, and replays offline without calling the provider. Ships shadow evaluation.
Jev Demos & Experiments#community#awesomejev#catalog-import
1GitHub stars
Experiment scoring Jev's decisions on a game with a known right answer: a fair die, exact payouts, one Bet-or-Skip call per offer, judged by expected value rather than by whether the roll wins. Across 12,000 decisions it accepts profitable bets but rarely refuses bad ones.
Jev Practices & Patterns#community#awesomejev#catalog-import
2GitHub stars
OpenCode extension putting a Jev-backed judgment layer between a coding agent and its tools. Four controllers, AEGIS, METIS, NIKE and EPISTEMICS, emit GO, DELIBERATE, VERIFY or BLOCK, and a tool router predicts the smallest useful capability set. Observe mode is the default.
Jev Agents & MCP#community#awesomejev#catalog-import
3GitHub stars
Research notes on Jev plus a Cloudflare Worker demo you can paste a support ticket into. Useful for the failure modes rather than the pitch: no arithmetic, unreliable date comparison, scores that are not measurements, and speed and cost figures from TypeSafe's own evaluations.
Jev Demos & Experiments#community#awesomejev#catalog-import
1GitHub stars
PlotVeil is a Chrome extension that hides YouTube comments until a single typed Noul decision says the comment gives away the video you are on. The rule text travels from the extension to a Cloudflare Worker, which batches up to 20 comments per call and never sees the word spoiler.
Jev Demos & Experiments#community#awesomejev#catalog-import
2GitHub stars
Jevegis wraps Jev into a single guardrail call for LLM apps: one request covering prompt injection, jailbreaks, credential and PII leaks, unauthorized actions, malicious code and indirect injection in retrieved documents, plus Trust & Safety moderation. It returns probabilities rather than booleans.
Jev Tools & CLIs#community#jevbest#catalog-import
1GitHub stars
Pong where the ball advances one segment per model decision, run as four lanes so you can watch a typed-decision model keep up with a court that structured-output chat models cannot.
Jev Demos & Experiments#community#jevbest#catalog-import
2GitHub stars
A Pi extension that catches the turn-ending "Continuing the run" reply and sends the agent back to it, gated on the latest user request actually containing a command to do work.
Jev Agents & MCP#community#jevbest#catalog-import
0GitHub stars
An experimental bench for writing a game ruleset and immediately watching it played: Jev is both the tool that explores the rules and the first player, one typed boolean per legal cell.
Jev Demos & Experiments#community#jevbest#catalog-import
1GitHub stars
An npm package that supervises a running agent: one Jev systemOne call per check returns six semantic signals about recent steps, and a deterministic policy in your own code turns them into CONTINUE, WARN, REPLAN or HALT.
Jev Agents & MCP#community#jevbest#catalog-import
0GitHub stars
A one-commit TypeScript MCP server that exposes three TypeSafe System One judgments — noul, choice and score — as agent tools, with src, tests, docs, scripts and a knip config. No README, zero stars, no topics.
Jev Agents & MCP#community#jevbest#catalog-import
A Turborepo proof of concept that replays a fictional ACME support call about once per second and schedules a real TypeSafe evaluation for every new turn, coalescing turns that arrive while a request is in flight and persisting evidence, confidence and score history to SQLite.
Jev Tools & CLIs#community#jevbest#catalog-import
A Next.js demo that sends one request of 36 independent questions to TypeSafe and renders a twelve-member council voting on your idea: each character answers approve, oppose or baffled, plus an enthusiasm score and a confusion probability.
Jev Demos & Experiments#community#jevbest#catalog-import
3GitHub stars
Emoji autocomplete where every pause in typing triggers one Jev call answering eight typed questions in parallel: an emoji choice, an emotion choice, three scores and three booleans, in about 100 ms of model time.
Jev Tools & CLIs#community#jevbest#catalog-import
0GitHub stars
Local TypeScript library and CLI for exploratory browser testing: Jev picks actions and judges observed results while Playwright executes them in isolated sessions, with trace files, reports and replay that needs no model calls.
Jev Demos & Experiments#community#jevbest#catalog-import
0GitHub stars
Repository navigation tool that pairs a lexical index and reference graph with small typed Jev judgments: Find narrows to candidate files, Map locates a subject's members, and Explain builds an evidence-backed graph.
Jev Tools & CLIs#community#jevbest#catalog-import
0GitHub stars
Shared 1,000 by 1,000 emoji canvas where Jev paints alongside visitors: after each stroke it picks a keyword-matching emoji and a named position relative to that stroke, and answers whether the stroke is unfinished.
Jev Tools & CLIs#community#jevbest#catalog-import
0GitHub stars
Local stdio MCP server that lets an agent delegate a decision: send a decision, context and 2 to 64 choices, get back a recommended choice with per-choice percentages and an explicit statement of where those percentages came from.
Jev Agents & MCP#community#jevbest#catalog-import
n8n community node for TypeSafe's System One API, exposing yes or no, choice and score questions as workflow nodes, with an Evaluate Questions operation that batches several over one state in a single request.
Jev Integrations & Adapters#community#jevbest#catalog-import
0GitHub stars
Reference TypeScript integration for Jev that keeps thresholds in your code and confidence bands in the type: a decision builder, runtime response validation, a rule fallback, and an eval CLI that refuses thresholds from thin data.
Jev Tools & CLIs#community#jevbest#catalog-import
1GitHub stars
A reference app for Jev's typed primitives: three use cases — support routing, compare-and-choose and content triage — behind one server-side SDK boundary, with a developer view of every question, threshold and token count.
Jev Tools & CLIs#community#jevbest#catalog-import
1GitHub stars
A Codex plugin that asks Jev which conversation passages still matter, lets Codex compact normally, then restores the selected excerpts verbatim afterwards with labels for their original role and tool source.
Jev Agents & MCP#community#jevbest#catalog-import
0GitHub stars
A Choice-only decision framework around Jev: a local rule engine answers reject, short-circuit, route and constrain cases with no remote call, and only misses reach a Choice request on TypeSafe, Cloudflare, Vercel or a self-hosted host.
Jev Integrations & Adapters#community#jevbest#catalog-import
0GitHub stars
A minimal Japanese walkthrough of calling Jev through the TypeScript SDK on Bun: install, set the key, run the SDK's own sample, then extra scripts covering Noul, placeholders, parallel calls and Japanese prompts.
Jev Demos & Experiments#community#jevbest#catalog-import
3GitHub stars
Fifteen independent local plugins for the Paseo desktop app, two of which use Jev: an evaluator exposed to Codex and Claude agents over MCP, and an orchestrator that routes a task to one model profile and effort level.
Jev Integrations & Adapters#community#jevbest#catalog-import
1GitHub stars
Upload a PDF and get an understandability and completeness judgment back in seconds: the browser extracts passages, a Cloudflare Worker judges each one in parallel with typed System One questions and visible rubric arithmetic.
Jev Demos & Experiments#community#jevbest#catalog-import
1GitHub stars
Plugin for Claude Code and Codex CLI that turns project rules into typed Jev questions a lifecycle hook uses to block a tool call or a final response, instead of trusting the agent to remember them.
Jev Agents & MCP#community#jevbest#catalog-import
A read-only market demo that pulls Coinbase trades for BTC, ETH and XRP, folds the last 60 seconds into up to twelve five-second OHLC samples, and asks one shared Jev request for a buy/wait call per coin.
Jev Demos & Experiments#community#jevbest#catalog-import
0GitHub stars
A browser-based planetary rover sandbox with a keyless local 3D baseline and an optional selectable TypeSafe controller, where every decision can be inspected, held in teaching mode, saved, replayed and compared against the baseline.
