Ad Spend Guard

A pre-bid spend guard that scores a placement's expected relevance and flags whether it matches the campaign brief, letting deterministic code hold budget back before the auction instead of gating the creative itself.

Listing Match

A real-estate matching tool that applies hard-constraint gates before ranking a buyer's property preferences against listing features and remarks, returning a fit band and a per-feature score for the agent.

profanity-checker

Cloudflare Worker that asks Jev on Workers AI for literal profanity in text or usernames and, for usernames, a second Noul for phonetic or look-alike disguises. The threshold and max policy live in Worker code, with OpenAPI docs generated via chanfana and Hono.

Polymarket BTC 5m Jev trader

Terminal agent for Polymarket's BTC Up or Down five-minute markets. Roughly every five seconds it asks Jev whether BTC finishes UP or DOWN versus the window open, then abstains or buys once and holds to resolution. Defaults to dry-run; live orders are opt-in.

24.9k

Open-source link attribution platform that calls typesafe-ai/jev in malicious-link-check.ts before a short link is created, so the URL is gated by a typed Jev verdict rather than a static blocklist. Next.js and TypeScript with an open-core license.

Jev Slop Guard

A bring-your-own-key Chrome extension that asks Jev one slop/not_slop Choice per X or LinkedIn post as it scrolls into view, then blurs and stamps anything at or above a configurable threshold. Scrolling never blocks, and each post is scored once from a local cache.

LinkScout

A browser extension plus Cloudflare Worker that scores search results before you click: Jev answers six questions per page (relevance, depth, SEO filler, sales page, page type, key passage) and code combines them into a 0-100 badge that re-ranks Google, Bing, DuckDuckGo and 104.com.tw.

dsh-jev-interceptor

A DeepSeek Harness plugin where Jev Choice and Noul checks gate every non-read-only tool call - deny confident high-risk calls, escalate ambiguous ones, auto-approve clearly granted reversible ones - and optionally score session messages so valuable context survives instead of being dropped oldest-first.

OpenClaw Jev Trigger

OpenClaw plugin and CLI that turn a plain-language --when/--not-when condition into a scheduled trigger script. Each tick sends one Noul through OpenClaw's decisionModel and only wakes the conversation model when the condition reaches 0.7 or above; a 76-tick benchmark reports 75 correct judgments and 0 false wake-ups.

MCP server that lets Claude Code, Cursor and other clients drive Chrome over the DevTools Protocol, exposing an accessibility-tree menu of stable refs.

lossless-compaction

Claude Code plugin that compacts conversations by moving old tool results to local files instead of summarizing them, leaving a ticket line in their place. When the agent needs something back, Jev can choose among the moved-out items in words for a `find`, while `recall` restores any item exactly by id.

Three.js simulation where an OpenAI model turns each plain-language instruction into a plan and Jev makes every reflex decision: two Score questions for move and turn plus one Noul for jump, with code acting only past a 0.33 dead zone and sending no Jev request while no step is active.

pi-verdict

Permission gate extension for the pi coding agent: deterministic allow/deny rules and protected paths settle clear cases first, then gray-zone tool calls get one structured classify() verdict; Jev is an optional native classifier via TypeSafe direct, OpenRouter, or other gateways, failing closed on error.
