It does not stack several requests into one message."},{"q":"What happens when I give it almost no information?","a":"It does not make up a story. On a nearly empty brief, the strong model wrote a role-based reason for the contact and stated openly that it was writing without prior contact. Give it real facts about the recipient and your offer for a sharper message."},{"q":"Is the small model good enough for this?","a":"Read every draft. Claude Haiku passed our mechanical checks but added claims that were not in the brief, such as what most customers say, flattered the recipient and skipped the formal form of address in German, Spanish and Bulgarian.
