kaustav1996/reflexTypeScript

read-with-jev

Next.js and TypeScript research prototype that reads whole novels with an eight-emotion JEV scoring layer and a character minimap, built for inspecting model output rather than measuring it.

A Claude Code function hook that sends AskUserQuestion dialogs to Jev and draws a probability per option above the dialog, so you still choose while seeing how confident the model is.

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

Community

BeLazy167/typesafe-modTypeScript

jevgpt

Chat client over jev-latest, which cannot generate text: the transcript becomes the state and each step is a choice over a 20,000-word dictionary, so replies are built one word at a time.

Bewinxed/jevgptTypeScript

clarity-judge

Writing evaluator that runs seven separate typed Jev checks, covering hedging, em dashes, clarity, filler phrases, tone, passive voice and actionability, and shows each verdict with its supporting sentence.

Community

BunsDev/clarity-judgeTypeScript

typesafe-ui

Unofficial community component workspace for TypeSafe AI projects: a Turborepo and pnpm monorepo with a Next.js component browser, shiki-highlighted source previews and an interactive Lab, built on shadcn base-nova, Base UI primitives, Tailwind v4 and RTL-aware components.

Community

Charlyhno-eng/jev-document-classificationTypeScript

mastra-jev-moderation

One-file Mastra input processor that screens the last user message with Jev instead of an LLM verdict: a typed yes/no gate plus a log-only category label, in a single request that fails open behind a circuit breaker.

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

Community

CodeAlive-AI/mastra-jev-moderationTypeScript

jev-ui

React library on npm where Jev judgments choose presentation: `Branch` picks a subtree, `Rank` orders or truncates a candidate set, `Gate` shows an affordance, and `useScore` returns a number you can use as an ordinary prop.

Jev Integrations & Adapters#community#jevbest#catalog-import

Community

etweisberg/jev-uiTypeScript

tiershift

Model router that asks Jev eleven questions in one call and lets a YAML policy turn the answers into a tier. Every request starts on the fast tier and only escalates on evidence such as multi-step reasoning, hard difficulty, high stakes or safety, and every decision is logged without the message text.

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

Community

iamvatsalpatel/tiershiftTypeScript

jev-lab

Two TypeScript monorepo products that keep the rules in the engine and ask Jev exactly one question: what should this person or this shogi side do next. Hundred runs a hundred NPCs with hunger, money, jobs, relationships and memories; Jev Shogi picks Gote's reply from engine-legal USI moves.

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

jammaru/jev-labTypeScript

jevpdf

PDF search that asks Jev one noul per line, does this line answer the query, and ranks the lines by the returned probability, so matches highlight without embeddings, a vector index or a chunking strategy. Text is extracted locally with pdf.js and the key stays on the server.

kylemclaren/jevpdfTypeScript

jev-workbench

Local service for authoring versioned judgment functions on TypeSafe Jev in a browser, then publishing one immutable version that both your backend calls over HTTP and your coding agents call over MCP, using a scoped client token.

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

Community

molis-ai/jev-workbenchTypeScript

jev-gate

Plugin for Claude Code and native Codex that layers Jev-assisted task routing, evidence search, context compaction and readable tool output on top of the host, where typed judgments inform policy but the host keeps ownership of permissions and execution.

MongLong0214/jev-gateTypeScript

otto

Open-source Electron computer-use agent for macOS and Windows that reads the apps you select through native accessibility with local OCR added for text targets, and asks Jev to choose concrete actions that it shows you before executing.

NobleSpartan6/ottoTypeScript

tripwire

TypeScript guardrail that puts seven Jev checks in front of an AI SDK model or an OpenAI-compatible endpoint, blocks on high-confidence hard checks, downgrades low confidence to a flag, and logs every verdict as a PII-free JSONL row you can turn into an eval set.

noelzappy/tripwireTypeScript

typesafe-migration-guard

Next.js service with a POST /api/migration-guard endpoint that asks Jev a SAFE or DANGER choice about a SQL statement plus target environment, returning HTTP 403 to halt a CI step or HTTP 200 to let Prisma migrations proceed against Postgres.

opaielsheikh/typesafe-migration-guardTypeScript

pi-fast-jev-compaction

pi extension that never summarizes: it asks Jev whether each old tool call and tool result is still needed, then drops or truncates only those, passing text, thinking and images through verbatim in a per-request view.

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

Community

QuentinDanblon/pi-fast-jev-compactionTypeScript

jevarena

Next.js spectator demo in which two independent Jev agents drive separate Snake browsers through same-origin iframes, clicking indexed direction buttons only, with each board state streamed to a server-only endpoint that returns the chosen target.

raihankhan-rk/jevarenaTypeScript

ailerix

Model router that never names a model: Jev classifies the task family, then a cost-per-task Pareto walk picks the cheapest frontier point clearing its quality floor.

tylerjharden/ailerixTypeScript

jev-shield

Manifest V3 ad blocker that scores candidate feed elements with Jev's noul primitive to collapse native ads, layered over network rules and a media engine.

git-jev-stage

Describe the change you want in one sentence and it classifies every diff hunk as include, exclude or mixed, prints the plan, then stages the hunks you confirm. It never writes the commit.

ibrahemid/git-jev-stageTypeScript

jevprune

Filters long command output for coding agents against a task description, keeping retained lines unchanged and in order, collapsing dropped runs into markers with a saved copy you can print back later.

pi-jev-context

Pi extension that uses Jev to judge which older session messages are still worth sending to the model, hiding low scorers from future requests while leaving the session transcript itself intact.

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

Community

kevinpita/pi-jev-contextTypeScript

pi-fast-jev-compaction

Pi package that uses Jev to decide, call by call, which old tool results can leave model context, with a savings gate that rejects prunes too small to be worth the prompt churn and bounded excerpts from status documents.
