 "repo_slug": "w3cj-jev-chat",
 "title": "Answer factual questions from Wikipedia and web search",
 "page_title": "How to answer factual questions from Wikipedia and web search with Jev Chat",
 "summary": "Get sourced facts from Wikipedia and Brave Search, with no model writing the answer.",
 "who": "A researcher or student who wants short factual answers pulled from a reference source and does not want a summary invented by a model.",
 "problem": "General chatbots blend memory and guesses into answers, so users cannot tell which facts came from a source.",
 "outcome": "Factual answers such as a mountain height or a podcast host, each built from Wikipedia or search tool data.",
 "steps": [
  "Run `pnpm install` in the repo folder.",
  "Run `cp .env.example .env`, set TYPESAFE_API_KEY, and add BRAVE_API_KEY if you want web search.",
  "Run `pnpm dev` and open http://localhost:5173.",
  "Type \"How tall is Mount Rainier?\" and \"Who hosts the Syntax podcast?\".",
  "Open the inspector pane for a reply to see which tool was called and what it returned."
 ],
 "agent_prompt": "In the jev-chat repo, run pnpm dev with TYPESAFE_API_KEY set in .env, then send \"How tall is Mount Rainier?\" to the chat at http://localhost:5173. Report the reply and the tool named in the inspector. Verify that the height value appears in the tool result shown in the inspector.",
 "agents": [
  "any"
 ],
 "difficulty": "Intermediate",
 "time": "30 minutes",
 "basis": "readme",
 "caveat": "Without BRAVE_API_KEY, only the no-key servers such as Wikipedia answer, so web search questions will not return results.",
 "category": "Personal productivity",
 "tags": [
  "Personal productivity"
 ],
 "lang": "typescript",
 "requirements": [
  "Node 24 or later and pnpm 11 (run corepack enable to pick up the pinned version)",
  "A TypeSafe API key in TYPESAFE_API_KEY, since Jev is a paid API and the app shows error replies without it",
  "A terminal and a local browser on the same machine, because the API only listens on 127.0.0.1"
