Keep coding agents oriented with an auto-updating OpenWiki

OpenWiki is LangChain's MIT-licensed CLI for generating and refreshing agent-friendly codebase documentation, with an optional GitHub Action that can open daily update PRs. OpenWiki is a CLI from LangChain that generates a repository wiki for coding agents and keeps that documentation close to the code. It is useful when AGENTS.md, CLAUDE.md, or similar instruction files are getting too crowded, but agents still need durable repo context before they edit files. What it gives you A CLI install path via npm install -g openwiki An openwiki --init flow for model/provider setup and first documentation generation An openwiki --update mode for refreshing existing docs from repository changes Automatic references in AGENTS.md and/or CLAUDE.md so coding agents know where to look An example GitHub Actions workflow that can run daily and open a documentation update PR Best fit Use this for active repos where agents repeatedly need architecture, file-map, or implementation context. It is especially relevant for teams moving between Codex, Claude Code, Cursor, or other coding agents and wanting repo knowledge that is not locked inside one chat thread. Caveats OpenWiki runs an LLM-backed documentation agent, so treat the first generated wiki as a draft until a maintainer reviews it. The GitHub Action example needs repository write permissions and model-provider secrets, so do not enable scheduled updates before checking your branch protection, secret scope, and review requirements. Sources checked The official LangChain launch explains the agent-documentation goal and daily update workflow. The GitHub repository confirms the CLI usage, MIT license, provider support, and example workflow. The HN thread is only used as public launch/discussion context, not as the factual source of record.
