What common mistake do developers make with Frequency, why does the mistake cause problems, and what is the safer approach? One recurring problem with frequency is applying it without understanding the boundary it protects. Defining a Laravel schedule but forgetting to configure the deployment environment so the scheduler is actually triggered. In addition, Schedules can express common intervals such as hourly, daily, weekly and other supported patterns. 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.
