New Plugin

• The user may pick one of the suggestions or provide their own slug and name.
• Confirm the final choice before proceeding.

Once the purpose and identity are confirmed, apply the find-plugin skill to determine whether:

• WordPress Core already provides the required functionality natively.
• A well-maintained plugin on WordPress.org already covers the need.

Only proceed to the steps below if Core and existing plugins do not cover the need, or if the user has explicitly agreed to build a custom plugin after reviewing the recommendation.

Step 1 — Gather remaining information

Scan packages/plugins/ for an existing plugin to use as a structural reference.

Step 2 — Create the directory structure

Block-library plugin:

packages/plugins/<plugin-slug>/
├── plugin.php             (plugin header + block auto-loader)
├── src/                   (block source directories — see add-block skill)
├── languages/
│   └── .gitkeep
├── package.json
├── composer.json
└── phpcs.xml

General plugin:

packages/plugins/<plugin-slug>/
├── plugin.php             (plugin header + bootstrap)
├── src/
│   ├── Plugin.php         (main class, singleton)
│   ├── Admin/             (admin screens — add if needed)
│   ├── Api/               (REST controllers — add if needed)
│   └── Frontend/          (front-end hooks — add if needed)
├── languages/
│   └── .gitkeep
├── package.json
├── composer.json
└── phpcs.xml

Step 3 — File contents

plugin.php

Block-library variant:

<?php
/**
 * Plugin Name:       <Plugin Title>
 * Description:       <Plugin description>
 * Version:           1.0.0
 * Requires at least: 6.4
 * Requires PHP:      8.1
 * Author:            Dekodeinteraktiv
 * Text Domain:       <plugin-slug>
 * Domain Path:       /languages
 *
 * @package <PhpNamespace>
 */

declare( strict_types=1 );

namespace <PhpNamespace>;

if ( ! defined( 'ABSPATH' ) ) {
	exit;
}

// Load all blocks (auto-discovered from build/).
foreach ( glob( __DIR__ . '/build/*/block.php' ) as $block ) {
	require_once $block;
}

/**
 * Load plugin text domain.
 */
function load_textdomain(): void {
	load_plugin_textdomain( '<plugin-slug>', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' );
}
add_action( 'init', __NAMESPACE__ . '\\load_textdomain' );

General plugin variant:

<?php
/**
 * Plugin Name:       <Plugin Title>
 * Description:       <Plugin description>
 * Version:           1.0.0
 * Requires at least: 6.4
 * Requires PHP:      8.1
 * Author:            Dekodeinteraktiv
 * Text Domain:       <plugin-slug>
 * Domain Path:       /languages
 *
 * @package <PhpNamespace>
 */

declare( strict_types=1 );

use <PhpNamespace>\Plugin;

if ( ! defined( 'ABSPATH' ) ) {
	exit;
}

require_once __DIR__ . '/vendor/autoload.php';

Plugin::instance()->hooks();

src/Plugin.php (general plugin only)

<?php
/**
 * Main plugin class.
 *
 * @package <PhpNamespace>
 */

declare( strict_types=1 );

namespace <PhpNamespace>;

/**
 * Plugin class.
 */
class Plugin {
	private static ?self $instance = null;

	private function __construct() {}

	public static function instance(): self {
		return self::$instance ??= new self();
	}

	public function hooks(): void {
		add_action( 'init', [ $this, 'init' ] );
		add_action( 'init', [ $this, 'load_textdomain' ] );

		// Registration hooks must be called in the plugin bootstrap file,
		// but we keep them here for discoverability.
		register_activation_hook( __FILE__, [ $this, 'activate' ] );
		register_deactivation_hook( __FILE__, [ $this, 'deactivate' ] );
	}

	public function init(): void {
		// Register CPTs, taxonomies, etc.
	}

	public function load_textdomain(): void {
		load_plugin_textdomain( '<plugin-slug>', false, dirname( plugin_basename( __FILE__ ) ) . '/languages' );
	}

	public function activate(): void {
		flush_rewrite_rules();
	}

	public function deactivate(): void {
		flush_rewrite_rules();
	}
}

composer.json

{
  "name": "dekode/<plugin-slug>",
  "description": "<Plugin description>",
  "type": "wordpress-plugin",
  "version": "1.0.0",
  "require": {},
  "autoload": {
    "psr-4": { "<PhpNamespace>\\": "src/" }
  },
  "scripts": {
    "make-pot": "wp i18n make-pot . languages/<plugin-slug>.pot --domain=<plugin-slug> --exclude=vendor,node_modules,build",
    "make-json": "wp i18n make-json languages/<plugin-slug>.pot languages --no-purge",
    "lint": "@php vendor/bin/phpcs",
    "lint-fix": "@php vendor/bin/phpcbf"
  },
  "config": {
    "allow-plugins": {
      "dealerdirect/phpcodesniffer-composer-installer": true
    }
  }
}

package.json

{
  "name": "@dekode/<plugin-slug>",
  "version": "1.0.0",
  "private": true,
  "description": "<Plugin description>",
  "scripts": {
    "build": "wp-scripts build --webpack-copy-php",
    "start": "wp-scripts start --webpack-copy-php",
    "lint:js": "wp-scripts lint-js src",
    "lint:css": "wp-scripts lint-style src",
    "format": "wp-scripts format src"
  },
  "devDependencies": {
    "@wordpress/scripts": "*"
  }
}

• Add any additional dependencies needed by blocks (e.g. @phosphor-icons/react for icons).

phpcs.xml

<?xml version="1.0"?>
<ruleset name="<Plugin Title>">
    <description>PHP CodeSniffer ruleset for <Plugin Title>.</description>
    <file>.</file>
    <arg name="extensions" value="php"/>
    <arg name="basepath" value="."/>
    <exclude-pattern>build/</exclude-pattern>
    <exclude-pattern>vendor/</exclude-pattern>
    <exclude-pattern>node_modules/</exclude-pattern>
    <rule ref="../../../phpcs.xml.dist"/>
</ruleset>

The ../../../phpcs.xml.dist path resolves to the root ruleset. Adjust the relative path if the plugin nesting differs.

Step 4 — Register in root workspaces

Root package.json — add the plugin to the workspaces array:

"workspaces": [
  "packages/plugins/<plugin-slug>"
]

Root composer.json — add a path repository and require the package:

"repositories": [
  {
    "type": "path",
    "url": "packages/plugins/<plugin-slug>"
  }
]

And in require:

"dekode/<plugin-slug>": "*"

Step 5 — Install and verify

composer install          # symlinks plugin into public/content/plugins/
npm install               # registers workspace
npm run build             # verify build passes
npm run lint:js
npm run lint:css
composer lint

After composer install, confirm the plugin is symlinked into public/content/plugins/<plugin-slug>/ and appears in the WordPress plugin list.

Confirm namespace matches the PSR-4 map in composer.json.

Conventions

• Namespace: Consistent PascalCase — check sibling plugins for the project's convention
• Block auto-loading: Block-library plugins always load blocks from build/*/block.php via glob — never require individual blocks manually in plugin.php
• No editing public/: Composer symlinks the plugin automatically; never manually copy files into public/content/
• No editing vendor/: All dependencies managed by Composer

Output

When done:

• packages/plugins/<plugin-slug>/plugin.php — WordPress plugin entry point
• packages/plugins/<plugin-slug>/composer.json — PHP package metadata
• packages/plugins/<plugin-slug>/package.json — JS build config
• packages/plugins/<plugin-slug>/phpcs.xml — PHP linting ruleset
• packages/plugins/<plugin-slug>/src/ — source directory (blocks for block-library; PHP classes for general)
• packages/plugins/<plugin-slug>/languages/ — translations directory

The plugin is symlinked into public/content/plugins/<plugin-slug>/ after composer install and is ready to receive blocks via the add-block skill.
