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.
