- Article · Agent workflowsJev Engineering: how to build the fastest AI Agent Brain in 10 StepsA ten-step walkthrough of putting Jev in the decision points of an agent: choosing workers, routing handoffs, batching questions, and stopping for review. Generative models still write; application code still executes.
- Guide · Getting startedJev GuideAn independent introduction to Jev with walkthroughs and recipes for routing a message, scoring urgency, and checking a reply. It pairs illustrative answer shapes with code and explains what each question does not prove.
- Guide · Getting startedGet started with Jev: API access and your first requestA step-by-step route from getting a TypeSafe API key to checking it and sending one Noul question with curl or TypeScript. It also explains common HTTP errors and how to keep the key on the server.
- Recipe · Agent workflowsPick a toolA Choice recipe for selecting one tool from a fixed list, including a “none” option. It shows why a close race between tools needs review and why choosing a tool name is not the same as supplying its arguments.
- Article · Browser useA deep dive into Jev, TypeSafe’s System One modelA broad, practical tour of Jev’s question types, JavaScript examples, confidence gates, limitations, and early projects. Its browser-agent section shows the split between a planner, Jev choosing from page actions, and code executing them.
- Article · GuardrailsBuilding a Harness with JevLangChain explains where Jev fits in an agent loop and shows classifier, model-router, and Auto Mode middleware examples. Its guardrail example checks proposed tool calls for risky actions before the agent executes them.
- Recipe · GuardrailsCheck a replyA Noul recipe for checking whether a draft addresses every explicit customer request. It makes the limitation clear: this is a coverage judgment, not a fact check or proof that a promised action happened.
- Guide · ClassificationHow to classify, route, and score with Jev and AI SDKA TypeScript tutorial that asks Choice, Score, and Boolean questions about one support ticket through AI SDK. It then branches on probability and confidence and tests the routing logic with a mock evaluation model.
- Recipe · ClassificationRoute a messageA Choice recipe that assigns support messages to billing, account, technical, sales, or other. The examples distinguish an obvious route from an ambiguous one and show how low confidence can hand off to a person.
