Built an agent that explains why X posts go viral instead of generating new ones

Most AI content tools do the same thing — generate, schedule, repeat. I went the opposite direction. Instead of "write me a post" — built an agent that answers "why did this post win." Feed it any X post. It breaks down: \- Hook structure \- Emotional trigger \- Reply bait signals \- Score vs account's own baseline The baseline part was the interesting engineering problem. Same post performs differently for a 500 account vs a 500K account. Needed account context to make the scores actually meaningful. Used Claude Sonnet for deep analysis, Haiku for scoring. Chain of thought internally before final output — reduces hallucinated reasoning a lot. Curious if anyone has tackled content analysis agents vs content generation. Feels like an underexplored direction.
