This npm library and Claude Code plugin compact history by pruning tool calls and results instead of rewriting conversation text. Jev answers separate noul questions about retaining each call and result; thresholds determine whether to keep, shorten or remove the pair.
The native CLI supports an interactive shell, scripted requests and embedding, with skills, MCP servers and subagents. Jev receives review policy, context and the pending action, returning a clear or caution decision for the permission pipeline.
Hermes Jev Skills provides reusable skills for model routing, search, memory filtering, triage and browser actions. Jev makes bounded choices such as selecting a model or ranking retrieved passages; the host model handles prose. The skills work with Hermes, Claude Code and Codex. Shadow mode records routing decisions without switching models.
DSCODE is a macOS coding agent whose terminal interface, CLI and scripts share a persistent session runtime. The repository includes a separate Jev client for OpenRouter’s alpha Decisions endpoint, supporting Choice, Score and Noul. Use sessions for editing, tests and agent handoffs; the Jev client requires an API key.
Jev Review scans Git diffs or complete codebases for correctness, security, reliability, compatibility and test coverage. Jev selects evidence, classifies mechanisms, scores severity and, when needed, uses Choice to select a reviewer. Code applies thresholds and workflow policy. Use Node.js 24+, Git and a TypeSafe key to generate JSON reports or inspect saved reviews locally.
Foreman supervises coding workers, assessing completion, requirements, test sufficiency and the need for human input. Jev evaluates checks; a deterministic Python arbiter selects whether to continue, steer, verify, stop or escalate. Supply a repository and job with Python 3.11+, a TypeSafe key and a configured coding-agent backend.
jev-router launches the native coding CLIs through a local proxy and selects a model tier for each new user turn. Install jev-router with npm, configure JEV_API_KEY, and launch jev-claude or jev-codex with an installed, authenticated upstream CLI.
jev-gateway routes tool decisions for coding agents through Jev while the usual language model handles other work. Install the npm package and start an existing authenticated agent with its jev- launcher, then configure the Jev provider once.
Open-source Claude Cowork / Codex / WorkBuddy alternative — a local-first AI office agent that turns one request into real PPTX, DOCX, XLSX and HTML files. Runs DeepSeek, Qwen, Doubao, Claude or Ollama (BYOK), MCP, and can drive Claude Code / Codex CLI. 开源 AI 办公助理，豆包办公 / 千问办公替代。
Claude Code plugin: trim long Bash output with TypeSafe Jev before the model sees it
TypeSafe Jev as a decision layer for the Pi coding agent: a measured tool-call gate plus jev_ask for typed, calibrated answers
《Jev 工程学：为 coding agent 而作》完整中文翻译 — 保留原结构与 7 张插图
Rust CLI powered by Jev from TypeSafe.ai that ranks agent skills for the next step using live session context. Includes Claude Code hooks, structured JSON, abstention, and local feedback. Requires a TypeSafe API key.
A calibrated context sieve for Claude Code: every tool result is judged by a System One model before it enters context.
Automatic project memory for Claude Code. Also works with Cursor and Codex.
Evidence-first search for AI agents / Claude Code & Codex & Pi & OMP & kimi & mcp

Semantic tool routing and typed System One decisions for the Pi coding agent using TypeSafe Jev
Local Claude Code and Codex plugin that bounds oversized and repeated tool output, preserving complete redacted artifacts. Runs locally, makes no LLM calls.
Everything you need to run TypeSafe's Jev with Claude Code: a tool-call guard, tier guard, file search, browser agent, review, belay, compaction and installers.
A standalone local-only Python MCP server that gives any IDE persistent, workspace-isolated memory. works with any IDE supporting MCP servers
A claude code plugin for jev
Claude Code / Codex / pi plugin that hands agent steps needing no text output to Jev (TypeSafe's judgment model) — measured p50 ~230 ms and ~$0.02 per 1,000 judgments, with typed escalation back to the LLM
