Need help analyzing Linkedin posts for the perfect value proposition hook? Let's figure out the best approach together.

Hi there, looking for some guidance on a prompt I'm putting together to analyze the last 5 linkedin posts of the contact for the hook that most matches up with our value proposition, but I'm having trouble getting the prompt to work properly. It probably needs 4.0, but there is too much text for that to happen, so I'm trying to figure out the best way to do this. Perhaps I need to break it up into multiple prompts or I should use legacy or something? Unclear on the best path here. Let me know if you have any ideas.
