How do I turn a broad business need into an AI agent's first assignment?
"Help me with marketing" leaves an AI agent too much to decide. Pick one finished job inside it, say who the work is for and which information to use, and ask for a draft you'll review. Test one piece before you ask for a whole library.
Say you have a content preparation AI agent. It could turn approved workshop notes into a draft article for professionals building their first AI agent. That's a job you can describe and review, and the rest of the content operation stays with you.
Put the source and the reader in the assignment. Something like: "Use these approved workshop notes to draft an article that answers one question a first-time builder has. Keep the examples from the notes. Do not invent a participant story, a quotation or a result. Give me the draft for review. Do not publish it."
The output needs a standard too. Ask for a title that states the question and an answer that gets to the point, with one action the reader can try. When the notes don't support an answer, the AI agent should tell you what's missing and leave the gap alone.
Then test one article before you request a library. Read it for whether it answers the question and whether every experience attributed to you is yours. If you'd have to rewrite the whole thing, tighten the assignment before you raise the volume.
No code goes into a brief like this, and it still takes judgment to decide what belongs in it. I'd start with one finished assignment and a clear review boundary, then build from what the test shows you.
