I am a business analyst and i write user stories for my projects regularly. I have got suggestions from people that the design instructions shouldn't be part of Jira story description.
When i say design instruction, which means where to show what? For eg. Where should be the label shown on the particular field? In the field, above the field or beside the field? I usually mention this in my stories, so it gives better clarity to my Devs and QAs.
but i want to know whether i doing it right, or not?
