metask-jev
1GitHub stars
An open-weight Jev-class lab: a candidate-logit scorer that turns state plus a bounded rubric into calibrated probabilities per option in a single forward pass, with no generation and no parsing.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communitymetask-ai/metask-jevPython
jev-codex-router-skill
3GitHub stars
A Codex Skill that hands Jev the task summary plus the host's real model list, so Jev picks a model and reasoning effort for an independent subtask and Codex executes with it.
Jev Agents & MCP#community#awesomejev#catalog-import
Community455-dIAO/jev-codex-router-skillPython
laya-serve
2GitHub stars
Archived. A Jev-compatible HTTP server that lets any Jev client run against local Laya weights instead of the TypeSafe API, serving POST /v1/systemone with typed choice, score and noul answers. Upstream laya now ships this natively.

jevbrief
6GitHub stars
A pip-installable Python package that sits between a noisy source and Jev: ten adapters condense logs, diffs, tool lists, traces, alerts and screens into small state with a reason for every drop, then record a replayable trace.
Jev Demos & Experiments#community#awesomejev#catalog-import
CommunityParthkomalwad/jevbriefPython
jev-dingtalk
1GitHub stars
A small Chinese-language DingTalk toolbox: the dws CLI pulls unread mail and chat into JSON, `jev mail` and `jev triage` classify it, and standard-library Python renders a report of who is waiting on a reply.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityikashana/jev-dingtalkPython
Jev_steer_or_queue
15GitHub stars
A Claude Code plugin, with a separate Codex folder, that classifies each message you send while the agent is working as steer, queue or interrupt, and holds the queued ones in a per-session FIFO for replay after the turn.
Jev Agents & MCP#community#awesomejev#catalog-import
CommunityLarkspur-Wang/Jev_steer_or_queuePython
bili-hardcore-jev
2GitHub stars
A single-file Python script that signs into Bilibili's hardcore member quiz after one QR scan, sends each multiple-choice question to Jev for a pick and a confidence, and submits a full round unattended.
Jev Tools & CLIs#community#awesomejev#catalog-import
Communityyanglei070-ux/bili-hardcore-jevPython
jev-router

open_system_one
2GitHub stars
An Apache-2.0 attempt at an open Jev: a System-1 decision model returning calibrated probabilities per option, with option branches packed so answers do not change when the option list is reordered.
Jev Practices & Patterns#community#awesomejev#catalog-import
CommunityReadyaddy/open_system_onePython
heyreach-jev-bot
5GitHub stars
Scores HeyReach leads and first-message variants with jev, then writes the ranking back as lead lists and DRAFT campaigns. The code can read your workspace and draft campaigns, but it cannot send anything.
Jev Tools & CLIs#community#awesomejev#catalog-import
Communitymatthew004-web/heyreach-jev-botPython
jev-trade-cc
5GitHub stars
A point-in-time backtest of a William O'Neil momentum strategy where jev picks the entries and decides the exits, paired against the same rules with no model — and honest enough to report the model as indistinguishable from them.
Jev Tools & CLIs#community#awesomejev#catalog-import
Communitymichaelpersonal/jev-trade-ccPython
jev-dllm
3GitHub stars
Reads typed probabilities out of a masked diffusion language model: a shared Yes/No head with a mask beside each candidate answers choice, boolean and ordered-score questions without generating text. Ships an S1 checkpoint, a 17-suite benchmark and a local HTTP service.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communityzhouzihao11/jev-dllmPython
llm2jev
8GitHub stars
Turns any chat model into a Jev-compatible decision service: state, question and all options go in one prefill, and the logprobs of the option labels at a single position become probabilities. Runs on SGLang, vLLM, transformers or MLX.
Jev Tools & CLIs#community#awesomejev#catalog-import
Communitytic-top/llm2jevPython
pydantic-jev-examples
4GitHub stars
Four small Pydantic AI demos that put a Jev question at a fixed hook, before the model runs, before a tool runs or after the run ends, and act on the number.
Jev Integrations & Adapters#community#jevbest#catalog-import
Communityadtyavrdhn/pydantic-jev-examplesPython
metis
2GitHub stars
GitHub issue triage that classifies a new issue as bug, feature, documentation, question or other, applies the matching label when thresholds pass, and asks for only the details it judged missing.

CommunityAyush0054/metisPython
judging-with-typesafe
1GitHub stars
A Letta agent skill that wraps TypeSafe System One (Jev) as a cheap external judge for texts and decisions, plus a paragraph scanner that maps where a document argues, lists, asks, or admits uncertainty. The README is in Russian.
Jev Integrations & Adapters#community#jevbest#catalog-import
Communitycarlsonchik/judging-with-typesafePython
paper-package
1GitHub stars
An evidence and reproduction package for a Jev decision study: the original fixed-split result on DBLP to ACM entity matching and SciFact relation verification, a later fresh repeat that did not resolve it, and the graph-synthesis work that followed.
Jev Practices & Patterns#community#jevbest#catalog-import
CommunityCompleteDotTech/paper-packagePython
tetrajev
1GitHub stars
Two frozen open-weight Qwen3.5 models read each task four ways, a letter and a pair readout each, and a fit-free fusion plus an agreement router turn those readings into calibrated decisions, with no fine-tuning and no distillation anywhere in the pipeline.
Jev Demos & Experiments#community#jevbest#catalog-import
CommunityFeiLiuEM/tetrajevPython
jev-subtitle-translator
9GitHub stars
An SRT translator and subtitle QC tool: cue numbers, order and timestamps are preserved locally, missing translations are retried by ID, and Jev flags each source and translation pair that may deserve human review. Web UI or CLI.
