What common mistake do developers make with Developer tooling, why does the mistake cause problems, and what is the safer approach? One recurring problem with developer tooling is applying it without understanding the boundary it protects. Treating Laravel as only a template engine instead of an application framework with routing, HTTP, database and service-layer capabilities. In addition, Laravel includes tools such as Artisan, migrations, database seeders, factories, queues, testing helpers and configuration facilities that support a complete application workflow. Safer engineering approach: keep the responsibility in the correct layer, use the framework's supported API, validate and authorize inputs, avoid hidden side effects, and verify the behavior with tests.
