# What Usuba is

Usuba is two parts, and they do different jobs. This page is the map of both.

-   **Usuba Checker Scripts** — the tests. Plain Python, not AI. They load an Omarchy plugin in a real Omarchy environment, run rule checks over its code, and report what is wrong and how to fix it. **Available now.**
-   **Usuba Checker Model** — the reviewer. A small AI model, trained only on Omarchy plugin data, that runs free on your own laptop. It is built to review a plugin the way an experienced Omarchy reviewer would. **In training.**

## Start with the Checker Scripts

[Section titled “Start with the Checker Scripts”](#start-with-the-checker-scripts)

They run today, on your own machine, for free.

-   [Install](/docs/checker/install/) — get the Checker Scripts onto your machine.
-   [Run a check](/docs/checker/run-a-check/) — check a plugin and read the output.
-   [Reading results](/docs/checker/reading-results/) — rule ids, warnings, and what a failure means.
-   [Usuba Standard v0.1](/docs/standard/) — the rulebook behind every result, with a rule id, a level and a fix for every failure. It is the document you check the Checker Scripts against.

## The model
