# About Rness

Who makes Rness, what it is and what it is not, and where its code lives.

Rness is one source of truth for every AI coding agent of a GitHub organization. Your organization's standards, decisions, specifications and plans live as Markdown in one repository, `.rness`, and the `rness` command writes the part that applies into the `AGENTS.md` of every repository. Claude Code, Codex, Cursor and GitHub Copilot already read that file, so nothing changes in how a team works.

## Who makes it

Rness is made in Paris, France, by Cédric Magne ([LinkedIn](https://www.linkedin.com/in/cedricmagne)), with a small team. It is open source under the MIT licence: the code, the issues and the discussions are public at [github.com/rness-dev](https://github.com/rness-dev), and the packages `@rness/cli`, `create-rness` and `@rness/create` are published on npm from that repository.

Rness is built with Rness: its own decisions, specifications and plans are kept in a `.rness` workspace and move on a GitHub Project as the work happens. This site describes what the published command does today; whatever it shows that is not built yet carries the words "not shipped yet".

## What it is, and what it is not

- A command-line tool on npm, `rness`, for Node 22.17 or later, with git.
- A local MCP server, `rness mcp`, that serves a workspace's context to any MCP client, read-only, started in the workspace by the agent.
- A Claude Code plugin with four commands, `/rness:status`, `/rness:adr`, `/rness:spec` and `/rness:plan`, written into each repository by `rness sync`.
- Not an agent: Rness never runs a model, and sends none of your code or context anywhere. A workspace is files in your repositories, on your machine and on your Git provider.
