dgui-hypermem
2GitHub stars
A self-hosted long-term memory MCP server on Cloudflare Workers: vector and full-text candidates fuse by reciprocal rank, then a Jev layer re-ranks them and assigns each memory a type, salience and durability.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityctaxnagomi/dgui-hypermemTypeScript
jev-mcp
2GitHub stars
Python MCP server exposing Jev System One as five typed tools, including a batched evaluate that runs a map of questions in one call, so agents consume probabilities instead of parsing prose.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityrajasekharponakala/jev-mcpPython
jev-rust-review
2GitHub stars
Claude Code plugin for Rust review that runs Clippy and cargo-semver-checks itself, has Jev triage changed units for defects no tool reports, then verifies each candidate finding before it reaches you.

Jev Agents & MCP#community#awesomejev#catalog-import
Community455-dIAO/jev-codex-router-skillPython
dsh-context-curator
2GitHub stars
A DSH compaction backend that swaps only the summarize() hook: instead of asking a model to rewrite history into a summary, it asks Jev two yes/no questions per tool call and drops only the stale ones, keeping user and assistant prose verbatim.

CommunityLXBWOW/dsh-context-curatorJavaScript
dsh-completion-supervisor
2GitHub stars
A DSH plugin that checks whether an agent's claim of finished work holds up, using deterministic evidence from code and one batched Jev request per turn. Under policy_v 3 the probabilities are logged only; they decide nothing.

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
jev-skills
6GitHub stars
A Claude Code and Codex plugin that keeps skill bodies off your prompt: a hook asks Jev, per turn, whether each skill's instructions would be used now, and injects only the ones above a threshold.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityeran-broder/jev-skillsTypeScript
jev-router
2GitHub stars
A Python CLI that asks Jev which of four coding agents should take a task, optionally waits for your approval, then opens that app or its website and pastes the prompt in.

CommunityBetterZflyee/dsh-jev-adapterJavaScript
jev-skillful
6GitHub stars
A per-prompt capability router for coding agents: a local BM25 shortlist of installed skills, MCP servers, subagents and commands, then one Jev request injects at most one suggestion plus two runner-ups.
Jev Agents & MCP#community#jevbest#catalog-import
Communitybestagentkits/jev-skillfulTypeScript
jev-mcp
3GitHub stars
An MCP server built around measuring questions rather than asking them: jev_ask prototypes wording, jev_eval sweeps thresholds against labeled data, jev_map applies the winner over a workload.
Jev Agents & MCP#community#jevbest#catalog-import
CommunityBYK/jev-mcpTypeScript
omp-statify
1GitHub stars
An Oh-my-pi extension that asks Jev which parts of large tool results are worth keeping before they enter the main model's context, and can also trim earlier plain-text assistant messages, keeping the original text locally for exact recovery.
Jev Agents & MCP#community#jevbest#catalog-import
Communityd3d0n/omp-statifyTypeScript
jev-predict-skill
4GitHub stars
A single-file host agent skill that reports what another skill's next closed decision would be, with a confidence and a probability over every outcome, by asking Jev to choose rather than by running the target skill at all.
Jev Agents & MCP#community#jevbest#catalog-import
CommunityDanielKillenberger/jev-predict-skillHTML
stepwarden
1GitHub stars
A Claude Code plugin that verifies every tool call before it runs, asking Jev five parallel questions about the plan, scope, prior action and stated intent, then allowing, asking or blocking. Fresh installs ship in audit mode.

jackalope
2GitHub stars
A Tauri desktop workspace for running coding agents side by side: parallel task queues in isolated Git worktrees, your existing agent sign-ins, and a review step before anything is merged.

CommunityJackalope-Dev/jackalopeRust
typesafe-assist
3GitHub stars
A Home Assistant Assist conversation agent that sends each command to Jev as one request with a speculative fan-out of questions, then hands the typed answers to Home Assistant's own intents to do the device control.

jev-toolkit
1GitHub stars
A small stdio MCP server that exposes three Jev-backed tools to coding agents: structured judgments, ranking supplied candidates by relevance, and checking claims against evidence you provide.

hunch
4GitHub stars
A CLI and agent skill that asks plain-English questions across a repository, sends each in-scope chunk to the provider, returns scored source locations to investigate, and runs recurring review rules on diffs.
Jev Agents & MCP#community#jevbest#catalog-import
CommunityKelbie/hunchTypeScript
psearch
1GitHub stars
A Python search command for terminals and agents: Parallel Search seeds queries, a local Chromium fetches pages concurrently, and Jev scores the evidence to expand a breadth-first link queue. Ships readable output, JSON and an MCP server.
Jev Demos & Experiments#community#jevbest#catalog-import
Communitykomikat/psearchPython
jev-routed-agent
4GitHub stars
