GitHub Copilot Instructions for Laravel 13

For full agent operating instructions and knowledge layer navigation, see:

• AGENTS.md
• agent/retrieval-guide.md
• agent/domain-routing-index.md

Architecture

• Use modular domain structure: app/Modules/{Feature}/
• Use Actions (execute() method) for single-purpose operations
• Use readonly DTOs for data transfer
• Use FormRequest for validation and authorization
• Follow Controller → Action → Domain Service → Contract → Infrastructure flow
• Always use constructor injection, never app() or resolve() in business code
• Depend on contracts, not concrete implementations
• Use facades only for infrastructure concerns (Cache, Log, DB)

Models (Laravel 13)

• Use PHP 8 attributes instead of properties:
  • #[Table('users', key: 'user_id')] instead of protected $table
  • #[Fillable(['name', 'email'])] instead of protected $fillable
  • #[Hidden(['password'])] instead of protected $hidden
  • #[Casts(['is_admin' => 'boolean'])] instead of protected $casts

Testing (Pest 4)

• Write tests before implementation (TDD)
• 80% feature tests, 20% unit tests
• Use Laravel fakes (Http, Mail, Queue, Storage, Event, Bus)
• Use RefreshDatabase trait for database tests
• Write architecture tests with Pest

test('example', function () {
    $response = $this->get('/');
    $response->assertOk();
});

Security

• Every model needs #[Fillable] or #[Guarded]
• All user input validated via FormRequest
• Blade {{ }} for output (auto-escaped)
• Rate limiting on all API endpoints
• CSRF on all web forms
• Authorization checks on all state-changing actions

Code Quality

./vendor/bin/pint               # Format code
./vendor/bin/phpstan analyse --level=6  # Static analysis
php artisan test --parallel      # Run tests

Queue Jobs

#[Connection('redis')]
#[Tries(3)]
#[Timeout(60)]
class ProcessJob implements ShouldQueue
{
    use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
}
