name: hyva-create-module description: Create a new Magento 2 module in app/code/. This skill should be used when the user wants to create a module, scaffold a new module, generate module boilerplate, or set up a custom module.

Trigger phrases include "create module", "new module", "scaffold module", "generate module". requires: hyva-exec-shell-cmd

Create Magento 2 Module

This utility skill creates new Magento 2 modules in app/code/. It is designed to be called by other skills that need module scaffolding.

Command execution: For commands that need to run inside the development environment (e.g., bin/magento), use the hyva-exec-shell-cmd skill to detect the environment and determine the appropriate command wrapper.

Parameters

When invoking this skill, the calling skill should provide:

Parameter	Required	Description
vendor	Yes	Vendor name in PascalCase (e.g., Acme)
module	Yes	Module name in PascalCase (e.g., CustomFeature)
description	No	Module description for composer.json (default: "[Vendor] [Module] module")
dependencies	No	Array of module dependencies for <sequence> in module.xml
composer_require	No	Object of composer requirements (package: version)

Workflow

Step 1: Validate Input

• Verify vendor name is PascalCase (starts with uppercase, alphanumeric only)
• Verify module name is PascalCase
• Check that app/code/{Vendor}/{Module} does not already exist

Step 2: Create Directory Structure

app/code/{Vendor}/{Module}/
├── registration.php
├── composer.json
└── etc/
    └── module.xml

Step 3: Generate Files

registration.php

Use template assets/templates/registration.php.tpl:

• Replace {{VENDOR}} with vendor name
• Replace {{MODULE}} with module name

composer.json

Use template assets/templates/composer.json.tpl:

• Replace {{VENDOR}} with vendor name (PascalCase)
• Replace {{MODULE}} with module name (PascalCase)
• Replace {{vendor_kebabcase}} with kebab-case, hyphenated vendor name
• Replace {{module_kebabcase}} with kebab-case, hyphenated module name
• Replace {{DESCRIPTION}} with description
• Add entries from composer_require parameter to the require section

module.xml

Use template assets/templates/module.xml.tpl:

• Replace {{VENDOR}} with PascalCase vendor name
• Replace {{MODULE}} with PascalCase module name
• Replace {{SEQUENCE}} with <sequence> block containing dependencies, or empty string if none

Step 4: Run Setup (Optional)

If the calling skill requests it, run bin/magento setup:upgrade using the hyva-exec-shell-cmd skill for the appropriate wrapper.

Error Handling

Abort module creation and report the error to the calling skill when:

Condition	Action
Vendor name not PascalCase	Report: "Invalid vendor name '{name}': must start with uppercase letter and contain only alphanumeric characters"
Module name not PascalCase	Report: "Invalid module name '{name}': must start with uppercase letter and contain only alphanumeric characters"
Directory already exists	Report: "Module already exists at app/code/{Vendor}/{Module}"
Cannot create directory	Report: "Failed to create directory app/code/{Vendor}/{Module}: {error}"
Cannot write file	Report: "Failed to write {filename}: {error}"

If hyva-exec-shell-cmd skill is unavailable when Step 4 is requested, skip the setup:upgrade step and report: "Skipped setup:upgrade - hyva-exec-shell-cmd skill not available. Run manually: bin/magento setup:upgrade"

Template Placeholders

Placeholder	Description	Example
{{VENDOR}}	Vendor name (PascalCase)	Acme
{{MODULE}}	Module name (PascalCase)	CustomFeature
{{vendor_kebabcase}}	Vendor name (kebab-case, split on capitals)	acme
{{module_kebabcase}}	Module name (kebab-case, split on capitals)	custom-feature
{{DESCRIPTION}}	Module description	Acme CustomFeature module
{{SEQUENCE}}	Module sequence XML or empty	<sequence><module name="Magento_Catalog"/></sequence>

PascalCase to kebab-case Conversion

Convert module names by inserting a hyphen before each capital letter and lowercasing:

PascalCase	kebab-case
CustomFeature	custom-feature
ShoppingCartGraphQl	shopping-cart-graph-ql
CmsComponents	cms-components
MyModule	my-module

Usage by Other Skills

Skills should reference this skill for module creation:

To create the module, use the `hyva-create-module` skill with:
- vendor: "Acme"
- module: "CmsComponents"
- dependencies: ["Hyva_CmsBase"]
- composer_require: {"hyva-themes/commerce-module-cms": "*"}

Example Output

For vendor Acme, module CmsComponents, with Hyva_CmsBase dependency:

app/code/Acme/CmsComponents/registration.php:

<?php
declare(strict_types=1);

use Magento\Framework\Component\ComponentRegistrar;

ComponentRegistrar::register(ComponentRegistrar::MODULE, 'Acme_CmsComponents', __DIR__);

app/code/Acme/CmsComponents/composer.json:

{
    "name": "acme/module-cms-components",
    "description": "Acme CmsComponents module",
    "type": "magento2-module",
    "require": {
        "php": ">=8.1",
        "hyva-themes/commerce-module-cms": "*"
    },
    "autoload": {
        "files": ["registration.php"],
        "psr-4": {
            "Acme\\CmsComponents\\": ""
        }
    }
}

app/code/Acme/CmsComponents/etc/module.xml:

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        xsi:noNamespaceSchemaLocation="urn:magento:framework:Module/etc/module.xsd">
    <module name="Acme_CmsComponents">
        <sequence>
            <module name="Hyva_CmsBase"/>
        </sequence>
    </module>
</config>
