Generating Permission Set

The real value is in the guardrails: it explicitly checks that you're not setting FLS on required fields, which is the number one reason permission set deployments fail. It handles the annoying naming conventions (custom tabs need __c, standard ones get the "standard-" prefix) and walks through the hierarchy of permissions in the right order. If you've ever had a permission set bomb during deployment because you accidentally included a required field or fat-fingered a tab name, this catches that before you waste a deployment slot.
