# What is BarnDog? (/docs)

BarnDog lets a company configure its AI coding environment once and ship it to every native coding harness: Claude Code, Codex, and Cursor today, with more to come.

Developers keep working in the tools they prefer. BarnDog sits above them as the place where the team's shared setup is built, reviewed, versioned, and distributed.

## What BarnDog does [#what-barndog-does]

BarnDog does two things.

1. **Developer environment management.** Each developer chooses the setup they want from the organization, their teams, and the repositories they work in. They can add individual assets on top. One command, `barndog sync`, writes that setup into every selected harness in the harness's own format.
2. **Collaborative asset development.** Developers create and improve shared assets together. Skills and Hooks get published versions, Suggested Changes, line-by-line review, and protected merges, much like code in a repository.

## What gets managed [#what-gets-managed]

BarnDog calls the things it manages **assets**. There are three kinds:

| Asset                 | What it is                                                                                              |
| --------------------- | ------------------------------------------------------------------------------------------------------- |
| **Skill**             | A package with a required `SKILL.md` plus any supporting files. Agents load it when it's relevant.      |
| **MCP configuration** | A connection definition for an MCP server. It names the secrets it needs but never stores their values. |
| **Hook**              | A command that runs when a lifecycle event happens, such as after a file edit.                          |

## Where you work [#where-you-work]

- **The web workspace** is where organizations, teams, repositories, and members are managed. It's also where you browse assets, edit in the browser, and review Suggested Changes.
- **The `barndog` CLI** runs on each developer's machine. It signs in, chooses harnesses, installs and syncs assets, and pulls, edits, and pushes Skills.

BarnDog is not another coding agent, IDE, or chat interface. It configures the agents you already have.
