jevcumber
3GitHub stars
Cucumber-style browser tests with no step definitions: Playwright opens the page, Jev picks among the controls actually present what each Gherkin step means, and a lockfile makes reruns deterministic.
Jev Demos & Experiments#community#awesomejev#catalog-import
CommunityRubyBrewsday/jevcumberTypeScript
actiongate-jev
2GitHub stars
A runtime authorization gateway for agent tool calls: deterministic policy plus six narrow Jev questions produce evidence, then a single-use grant bound to the exact approved action is consumed at execution.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityomkarghugarkar007/actiongate-jevTypeScript
toolgate
22GitHub stars
A calibrated tool-call firewall for coding agents: seven typed risk questions plus one question about whether the task authorized the call decide whether a Bash, Write or MCP action runs, asks, or is denied.
Jev Practices & Patterns#community#awesomejev#catalog-import
CommunityRiskAverseTech/toolgateTypeScript
Winnow
3GitHub stars
A Chrome extension that scores articles, videos and feed links with a fixed set of typed Jev questions and turns the probabilities into a read, skim, save or skip verdict, with the thresholds in options.
Jev Demos & Experiments#community#awesomejev#catalog-import
CommunityThinkyMiner/WinnowTypeScript
jev-starter
2GitHub stars
A TypeScript starter for the layer around the model: decision contracts, confidence thresholds that route to auto, fallback or human review, deterministic mock providers, and an offline evaluation harness.
Jev Practices & Patterns#community#awesomejev#catalog-import
Communityhamakyo/jev-starterTypeScript
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-pii-checker
3GitHub stars
A CLI that scans text and files for PII in three layers — thirteen typed category questions plus a sensitivity score, regex extraction, and Intl.Segmenter name candidates judged by Jev — with masked output and exit codes.

Communitycoo-quack/jev-pii-checkerTypeScript
jev-cloud-quiz
2GitHub stars

Communityminorun365/jev-cloud-quizTypeScript
Jev-chooses-a-LLM
4GitHub stars
Cursor router that has Jev pick a cost, balanced or intelligence tier per task, then enforces deterministic policy on top: security-sensitive work escalates and financial or deploy actions need approval.
Jev Agents & MCP#community#awesomejev#catalog-import
CommunityBodila51/Jev-chooses-a-LLMTypeScript
Postmark
2GitHub stars
Next.js demo that reads a draft social post and returns three typed reads from one Jev call: tone as a Choice, virality as a 0 to 3 Score, cringe risk as a Noul, plus a verdict stamp.

Jev Tools & CLIs#community#awesomejev#catalog-import
Communityzhengge6/haoganTypeScript
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
opencode-context-pruner
4GitHub stars
An OpenCode plugin that asks Jev, per tool call, whether the call and its result are still needed, then drops or truncates them in the outgoing request while leaving your saved history untouched.
Jev Agents & MCP#community#awesomejev#catalog-import
Communityhoshinodis/opencode-context-prunerTypeScript
jev-crush
2GitHub stars
Paste a two-person chat into a local Node app and get jev's read of it: emotion and intent on their messages, a rating on yours, one favourability score for the exchange, and a scenario selector so mentor concern is not scored as romance.
Jev Tools & CLIs#community#awesomejev#catalog-import
Communityzhengge6/jev-crushTypeScript
rubikjev
7GitHub stars
A single-page Rubik's cube playground where jev rates your scramble, then solves it one move at a time: each turn is judged from the live cube state, streamed to a 3D cube over SSE, and verified against a reference model before it animates.
Jev Demos & Experiments#community#jevbest#catalog-import
Community0xtrou/rubikjevTypeScript
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

Communityd3d0n/omp-statifyTypeScript
barrunto
2GitHub stars
A Chrome extension that asks Jev closed yes/no questions about the pages you browse and hangs a label on each item from a rule pack, with per-site sensitivity, read-ahead, optional fading or hiding, and a tuning mode that shows how every judgment was reached.

Communityelpumberto/barruntoTypeScript
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.
Jev Agents & MCP#community#jevbest#catalog-import
Communitygetexcited/stepwardenTypeScript
pi-jev
10GitHub stars
Two pi extensions driven by Jev judgments: one replaces summary-based context compaction with keep, drop and shorten calls, the other scores each prompt for difficulty and switches pi's model before the turn runs.
Jev Agents & MCP#community#jevbest#catalog-import

An MCP server with a single evaluate_decision tool that returns noul, choice or score probabilities over a diff, log or plan, with output tokens set to zero on every call.
