Composer Extension for Symfony AI Mate
======================================

[](#composer-extension-for-symfony-ai-mate)

Composer dependency management tools for AI assistants, with compact encoded output tailored for token-efficient workflows.

Features
--------

[](#features)

- install, require, remove, update, and explain Composer operations
- `composer://config` resource for project dependency context
- core Mate encoded output for compact responses
- custom command support for Docker or wrapper-based setups

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

[](#installation)

```
composer require --dev matesofmate/composer-extension
vendor/bin/mate init
```

In current AI Mate setups, extension discovery is handled automatically after Composer install and update. Use `vendor/bin/mate discover` when you want to refresh discovery artifacts such as `mate/AGENT_INSTRUCTIONS.md`.

Use these commands when troubleshooting:

```
vendor/bin/mate debug:extensions
vendor/bin/mate debug:capabilities
vendor/bin/mate mcp:tools:list --extension=matesofmate/composer-extension
```

For Codex, use the generated wrapper:

```
./bin/codex
```

Custom Command Configuration
----------------------------

[](#custom-command-configuration)

If Composer must run through Docker or another wrapper, configure `matesofmate_composer.custom_command`.

```
use Symfony\Component\DependencyInjection\Loader\Configurator\ContainerConfigurator;

return static function (ContainerConfigurator $container): void {
    $container->parameters()->set('matesofmate_composer.custom_command', [
        'docker', 'compose', 'exec', 'php', 'composer',
    ]);
};
```

Requirements
------------

[](#requirements)

- PHP 8.2+
- Symfony AI Mate 0.8+ required
- Composer available locally, or `matesofmate_composer.custom_command` configured

Available Tools
---------------

[](#available-tools)

- `composer-install`
- `composer-remove`
- `composer-require`
- `composer-update`
- `composer-explain`

All tools return encoded strings through Mate's core `ResponseEncoder`. Install the suggested `helgesverre/toon` package if you want TOON responses; otherwise the same payload falls back to JSON.

Available Resource
------------------

[](#available-resource)

- `composer://config`

This resource exposes `composer.json` content as an encoded structured payload.

Development
-----------

[](#development)

```
composer install
composer test
composer lint
composer fix
```
