Ragu — Documentation skill for Claude Code

A knowledge base that stays true to your code — and that your agents can actually use.

Ragu gives you a markdown knowledge base for business rules, flows, integrations and decisions, with three things most doc setups lack:

1. Every page cites the code it describes (sources: api/src/billing/refund.ts:42), and the build fails when a citation or a link breaks.
2. Agents read it over MCP — locally in one command, or remotely on Cloudflare with semantic search.
3. A Claude Code plugin keeps it in sync. When code changes and the docs don't, the agent is stopped with the exact list of pages that cite the changed files, before it declares the task done.

Humans get a [Starlight](https://starlight.astro.build) site and an Obsidian vault from the same files. Nothing is hidden behind a service: it is markdown, a JSON config, and a few hundred lines of Node.
