OpenWiki for Claude Code

A Claude Code plugin marketplace that brings OpenWiki into Claude Code — generating and maintaining agent-facing repo documentation using Claude Code's own inference, with no separate API key.

OpenWiki is LangChain's tool for writing and maintaining docs "built specifically for agents." Its CLI needs its own paid inference key. Claude Code users already pay for inference — so this plugin makes the Claude Code agent itself the engine, producing the exact same on-disk format so the two are interoperable.

Install

/plugin marketplace add arunkk/openwiki-for-coding-agents
/plugin install openwiki@openwiki-for-claude-code

Then:

/openwiki:generate          # build the wiki
/openwiki:update            # refresh it from recent commits
/openwiki:ask <question>    # ask the wiki
/openwiki:schedule          # keep it fresh automatically (keyless)

What you get

• openwiki/quickstart.md + focused section pages (architecture, workflows, domain, operations, testing, …) — evidence-grounded, with inline source references.
• openwiki/.last-update.json run metadata and an AGENTS.md/CLAUDE.md reference section, in the exact shape the OpenWiki CLI uses.
• Surgical, git-diff-driven updates and a no-op when nothing relevant changed.

See plugins/openwiki/README.md for details and plugins/openwiki/reference/openwiki-format.md for the format spec.

Two audiences

• Claude Code users get OpenWiki-style docs natively and keyless.
• Existing OpenWiki users can drive/refresh their wikis from Claude Code workflows; because the format matches, the CLI and this plugin can maintain the same wiki interchangeably.

Relationship to upstream OpenWiki

This project reimplements OpenWiki's methodology and on-disk format (from langchain-ai/openwiki, MIT) so a host coding agent can be the inference engine. It ships standalone; it is also intended as a proposal to upstream as an "OpenWiki Claude Code mode." Not affiliated with or endorsed by LangChain.
