What examples should we give an AI writing workflow?
I'd treat a set of approved brand writing as a teaching tool for your AI writing workflow. Pick a few examples your team is permitted to use, explain why each one worked, and add a near miss with its correction. Then ask the workflow to apply the principle to something new.
Approved pieces on their own can lead a workflow to repeat phrases that don't fit the new assignment. Context helps with that. Say who each example was for and why it worked. Mark any details that are historical so they don't travel into a current draft.
The near miss matters. A reviewed contrast, with the correction and the reason for it, can show where a boundary sits more clearly than a long list of positive adjectives.
When you prompt, ask for the principle applied to a new situation, in new wording. Then check that the result answers the new reader's question and the facts are current. Update the set as the brand's work changes. Think of the set as a practical explanation of judgment, which helps people tell a consistent voice from an imitation of the same few sentences.
