Description

Brace Sproul from LangChain introduces OpenWiki, a new open source agent and CLI that generates and maintains documentation for your codebase so coding agents have the context they need to make better changes. Built on DeepAgents with optional LangSmith tracing, OpenWiki creates a repo wiki, links it into your AGENTS.md file, and keeps everything current with a scheduled GitHub Action. In this walkthrough, Brace installs OpenWiki, runs through setup, tours the generated docs, and shows how your coding agent picks all of it up automatically. OpenWiki GitHub repository: https://github.com/langchain-ai/openwiki NPM package: https://www.npmjs.com/package/openwiki Chapters: 0:00 What OpenWiki is and why it exists 0:15 Installing OpenWiki with one npm command 0:25 Onboarding and picking a model provider 0:56 Optional LangSmith tracing setup 1:13 Generating your first docs 1:20 Touring the generated documentation 2:59 Why docs need to stay up to date 3:07 Automating updates with a GitHub Action 4:12 Chatting directly with the OpenWiki agent 4:50 How your coding agent actually uses the docs 6:00 What's next and how to contribute
