Research direction

Start by tracing where CLI arguments are parsed and validated and where print_task_help is defined or called. Determine how a task-raised exception should trigger usage output, then verify the behavior for invalid arguments detected during task execution.

Description

Feature Needs patch

It's a common pattern in CLI tools to print the help/usage if the arguments given are inconsistent or not valid.

This is something that can only be detected during the execution when the arguments are parsed and validated.

It would be useful to have a way to trigger the print_task_help function from the task itself (eg: by raising a specific exception) when that happens.
