Jev Langgraph

Korean-language Fastcampus seminar repo that teaches attaching Jev to a DeepAgents (LangGraph) shopping-mall support agent across 13 notebooks and a React sample app: tool selection, guardrails, risk gates and grounded RAG.

A LangGraph agent for the Forward Deployed Engineer role that classifies incoming support tickets with a Jev decision node, auto-closes basic issues to Tier 1 and sends technical ones to an LLM summarizer. The README notes Jev is mocked by a standard LLM in this demo.

A confidence-aware decision gate for autonomous software changes. It runs an explicit LangGraph flow of inspect, checks and evaluate, then routes each proposal to apply, human review or stop; the decision provider can be the TypeSafe Jev API.

A Streamlit lab that places a bounded System One decision inside a coding-agent workflow: Laya classifies CI failures, LangGraph applies a fallback policy, and an OpenAI agent inspects a fixture repo and proposes a fix.

Tenuo's engineering write-up of safe-upgrade, a dependency-upgrade agent built on Jev, LangGraph and Tenuo: Jev turns repository evidence into typed probabilistic choices, the graph routes on confidence, and each action gets a short-lived task-scoped warrant.
