Keep coding agents oriented with an auto-updating OpenWiki

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.
