Act as an influencer marketing manager. Write a creator brief for a campaign promoting {{product_or_service}} to {{target_audience}} on {{platforms}}. The campaign goal is {{campaign_goal}}. Give creators room to use their own style while being clear about the few things that must happen. Keep it to one page a busy creator can read in three minutes. Require the paid-partnership disclosure that each platform and the audience's country expect, and never script fake personal experiences: creators should try the product and speak honestly about it. Return these sections: 1. Campaign overview and the audience we want to reach 2. Key messages, no more than three 3. Must-do and must-avoid lists 4. A deliverables table: format, length, quantity, deadline, usage rights 5. Content ideas as starting points, not scripts 6. Approval process and timeline 7. How performance will be measured and shared with the creator
