When you did tests, what limit did you run into? Since the description is shown to customers on the store, anything > 256 characters would likely be considered too much, but it could in fact be much less. How much did you manage to cram in before it bombed?

What are the max sizes for those fields? https://shopify.dev/api/admin-rest/2021-10/resources/carrierservice#top does not specify the field max sizes.
