GitHub - langchain-ai/openwiki: OpenWiki is a CLI that writes and maintains agent documentation for your codebase.

OpenWiki is a CLI that writes and maintains documentation for your codebase, built specifically for agents.

Install npm install -g openwiki Quick Start Initialize OpenWiki, configure your model and API key, then generate documentation openwiki --init Then to ensure your documentation stays up-to-date, add the GitHub action to your repository to automatically open a PR once a day with documentation updates: openwiki-update.yml Copy the contents of that file into .github/workflows/openwiki-update.yml in your repository. Usage Start the interactive CLI: openwiki Start OpenWiki with an initial request: openwiki "Please generate documentation for this repository" Run a single command and exit: openwiki -p "Summarize what you can do" Initialize OpenWiki: openwiki --init Update existing documentation: openwiki --update Show help: openwiki --help openwiki creates initial documentation in openwiki/ when no wiki exists. If openwiki/ already exists, it refreshes that documentation from repository changes. By default, the CLI stays open after each run so you can send follow-up messages. Use -p or --print for a one-shot non-interactive run that prints the final assistant output. openwiki will automatically append prompting to your AGENTS.md and/or CLAUDE.md files to instruct your coding agent to reference it when searching for context. If the file does not already exist in your repository, OpenWiki will create it for you. On the first interactive run, OpenWiki will have you configure your inference provider, API key, and LLM. You will also be able to set a LangSmith API key to trace your OpenWiki runs to a LangSmith tracing project named "openwiki" (optional). These configuration options and secrets will be saved to ~/.openwiki/.env on your local machine. Customizing OpenWiki supports OpenRouter, Fireworks, Baseten, OpenAI and Anthropic out of the box. By default, there are a few models pre-defined (GLM 5.2, Kimi K2.6, Sonnet 5, etc) but for each inference provider, OpenWiki will allow you to specify your own custom model ID. If there's an inference provider or model you'd like to see added, please open a PR!
