Sylius Mate Extension
=====================

[](#sylius-mate-extension)

Dev-only Symfony AI Mate extension exposing the Sylius runtime domain to AI assistants via MCP.

About
-----

[](#about)

The Sylius Mate Extension is an [AI Mate](https://symfony.com/doc/current/ai/components/mate.html) extension for [**Sylius**](https://sylius.com). It exposes the Sylius runtime domain — resources, hooks, grids, routes, services, Twig helpers, mailer configuration — to AI assistants over the [Model Context Protocol (MCP)](https://modelcontextprotocol.io).

Every tool runs against the host project's booted Symfony kernel, so listings, inspections, and audits reflect the real container, real grid configuration, real route map, real installed plugins. Agents generate Sylius code against the actual shape of your application instead of hallucinating Twig helpers, routes, or resource patterns.

The extension is **dev-only**. Install it as a `require-dev` dependency; never ship it to production.

Documentation
-------------

[](#documentation)

See [INSTRUCTIONS.md](INSTRUCTIONS.md) for the full description of every MCP tool, when to call it, and the hard rules agents must follow (Twig helper verification, route lookup, resource scaffolding, mutating-tool confirmation).

General Sylius documentation is available at [docs.sylius.com](https://docs.sylius.com).

Installation
------------

[](#installation)

Add the extension as a dev dependency of your Sylius project:

```
$ composer require --dev sylius/sylius-mate-extension
```

Initialize the Mate environment and discover the extension:

```
$ vendor/bin/mate init
$ vendor/bin/mate discover
```

Extension discovery runs automatically after Composer install and update. Run `vendor/bin/mate discover` manually to refresh discovery state and regenerate agent instruction artifacts.
