AI Agent Instructions

For Jules, Devin, and other autonomous coding agents.

Quick Start

1. This is a Laravel 12 + Livewire 3 application
2. Modules go in app/Mod/{Name}/Boot.php
3. Use UK English (colour, not color)
4. Run vendor/bin/pint --dirty before committing
5. Run vendor/bin/pest to test

Architecture

Modular monolith - Features are self-contained modules that register via events.

Creating a Module

php artisan make:mod {Name} --all

Or manually create app/Mod/{Name}/Boot.php:

<?php

declare(strict_types=1);

namespace App\Mod\{Name};

use Core\Events\WebRoutesRegistering;

class Boot
{
    public static array $listens = [
        WebRoutesRegistering::class => 'onWebRoutes',
    ];

    public function onWebRoutes(WebRoutesRegistering $event): void
    {
        $event->routes(fn() => require __DIR__.'/Routes/web.php');
        $event->views('{name}', __DIR__.'/Views');
    }
}

Task Checklist

When implementing features:

• Create module in app/Mod/{Name}/
• Add Boot.php with event listeners
• Create routes in Routes/web.php or Routes/api.php
• Create Livewire components in Livewire/
• Create Blade views in Views/
• Add migrations in Migrations/
• Write tests in Tests/
• Run vendor/bin/pint --dirty
• Run vendor/bin/pest

File Locations

What	Where
Models	app/Mod/{Name}/Models/
Livewire	app/Mod/{Name}/Livewire/
Views	app/Mod/{Name}/Views/
Routes	app/Mod/{Name}/Routes/
Migrations	app/Mod/{Name}/Migrations/
Tests	app/Mod/{Name}/Tests/
Services	app/Mod/{Name}/Services/

Critical Rules

1. UK English - colour, organisation, centre (never American spellings)
2. Strict types - declare(strict_types=1); in every PHP file
3. Type hints - All parameters and return types
4. Flux Pro - Use Flux components, not vanilla Alpine
5. Font Awesome - Use FA icons, not Heroicons
6. Pest - Write tests using Pest syntax, not PHPUnit

Example Livewire Component

<?php

declare(strict_types=1);

namespace App\Mod\Blog\Livewire;

use App\Mod\Blog\Models\Post;
use Illuminate\Contracts\View\View;
use Livewire\Component;
use Livewire\WithPagination;

class PostListPage extends Component
{
    use WithPagination;

    public function render(): View
    {
        return view('blog::posts.index', [
            'posts' => Post::latest()->paginate(10),
        ]);
    }
}

Testing Example

<?php

use App\Mod\Blog\Models\Post;

it('displays posts on the index page', function () {
    $posts = Post::factory()->count(3)->create();

    $this->get('/blog')
        ->assertOk()
        ->assertSee($posts->first()->title);
});
