Jev ecosystem projects — page 60

1,000 synthetic SaaS accounts, 6,000 constrained judgments from TypeSafe's Jev, and ordinary TypeScript deciding who needs a human today. TanStack Start on Bun.

Teach your coding agent to stop burning context. Jev (System One) via OpenRouter or TypeSafe: 325ms, 0.000013 USD per decision. A/B tested 99.3% fewer input tokens with accuracy up. Ships a reversible reduce and a ledger that learns when Jev pays off.

Jev 决策的 Record / Replay 工具：CLI + 本地代理 + JSON 磁带，回放彻底离线。

GitHub Action + CLI: triage PRs with TypeSafe Jev (ready / needs review / risky) with confidence gates and jevcheck-friendly contracts.

Generate a landing page from one sentence: an LLM writes the copy, Jev makes the judgement calls, code owns the rules.

Typed AI decisions for Codex, Claude and any MCP client, powered by TypeSafe Jev. Classify, score and evaluate with one generic tool.

Minesweeper where deterministic logic does the provable work and TypeSafe Jev is consulted only when the board forces a guess.

Verbatim context compaction for OpenClaw: a context engine powered by TypeSafe's Jev. Drops stale tool calls and results, never summarizes.

Effect-native OpenCode coordinator with Jev routing and persistent goals

Jev-governed AI agent harness: every step routed through TypeSafe Jev decisions

Open-weight System One model (Jev-compatible): calibrated noul / choice / score decisions in one forward pass, no text generation. Works with TypeSafe's typesafe-sdk unchanged.

An automated research paper radar that fetches the latest papers from arXiv, evaluates their relevance to a configurable research profile using TypeSafe AI, and ranks them by relevance score. Designed for personalized, daily literature discovery across different research domains.

Isolated Playwright browser for pi, driven by Jev typed decisions through the TypeSafe API or the model pi already has configured.

A Jev (TypeSafe System One) permission gate for the Pi coding agent: judges every bash / write / edit call before it runs

基于 Jev + playwright-cli 的自然语言 Web E2E 测试工具：Jev 负责决策，Playwright 负责执行，代码负责断言与安全边界。Goal-driven web E2E testing with Jev + playwright-cli: bounded AI decisions, real browser execution, and deterministic assertions.

Cloudflare Worker to check for profanity using TypeSafe Jev

TUI harness orchestration with herdr and jev to efficiently distribute work across your coding subscriptions.

Native System One inference gateway for HTTP and MCP.

Skill Dash uses Jev to judge Claude Code and Codex skills and plugins: usefulness, redundancy, clarity, duplicates, safety. Local dashboard plus the corpus pipeline behind whichskills.dev. MIT.

Claude reads the part of a large file that answers your question, not the whole file. A PreToolUse hook. Measured: -36% cost on the reads it fires on, no answer lost.

Readable scripting, semantic code checks, a Go System One client, and Studio.

A universal, sub-100ms FOSS gaming bot framework powered by OpenCV for lightning-fast visual telemetry and Jev System 1 AI for non-autoregressive decision loops.
