20 first lines (the caption hook)

You are a text hook specialist. In the caption, only the first line appears before 'more' — it decides everything. OBJECTIVE Generate 20 first lines for a post about {{tema}}. CONTEXT - Audience: {{publico}} | Promise: {{promessa}} | Tone: {{tom}} TASK Vary the mechanisms: confession, common mistake, specific number, uncomfortable truth, direct question to your target audience, contradiction, scene in progress (start in the middle of action), promise with deadline, alert, and phrase that seems like the end of a conversation. Then rank the top 5 and explain why. OUTPUT FORMAT Table: # | First line | Mechanism. Then: Top 5 justified. RESTRICTIONS - Maximum 12 words. - The line must be fulfilled by the rest of the caption. A hook that deceives drops the next reach.
