Why is Command discovery important in Laravel applications, and what problem does it solve for developers? The key reason to understand command discovery is that Laravel applications are usually composed of several layers that must work together predictably. Artisan can list available commands so developers can inspect what the current application or installed packages expose. Ignoring that boundary can lead to duplicated logic, poor security, unnecessary database work, or code that is difficult to test. Why it matters in practice: Artisan is Laravel's command-line interface for generating code, inspecting the application, running migrations, clearing caches and executing custom commands. The specific focus here is command discovery: Artisan can list available commands so developers can inspect what the current application or installed packages expose. This question is designed to test not only terminology, but also how the concept fits into Laravel's request, application, database, security, or deployment workflow.
