# Codex

The AddressZen skills package ships a `.codex-plugin/` manifest. One install command covers Codex.

## Install[​](#install "Direct link to Install")

```
npx skills add addresszen/skills
```

Skills installed:

* `azn-address-lookup` — international address autocomplete widget
* `azn-api-integration` — direct HTTP integration
* `azn-react` — React bindings for the widget

## Verify[​](#verify "Direct link to Verify")

Ask Codex:

```
How do I add international address autocomplete to a checkout form using AddressZen?
```

Codex should load the `azn-address-lookup` skill and quote the `setup()` call rather than guessing.
