Did you know X's recommendation algorithm is open source?
I turned it into a Claude Code skill that analyzes your posts for viral potential.
What it does
Just ask Claude:
- "Check if this will go viral: [your post]"
- "Optimize my post: [your post]"
It scores your post across 8 factors:
| Factor | Max Points |
|---|---|
| Reply Potential | 25 |
| Repost Potential | 20 |
| Favorite Potential | 15 |
| Quote Potential | 12 |
| Dwell Time | 10 |
| Share Potential | 8 |
| Profile Click | 5 |
| Follow Potential | 5 |
Then it gives you a grade (S to F) and specific improvement suggestions.
The result?
I tested it on my own posts and got 13/100 (Grade: F) π
Apparently my "hilarious" jokes lack "emotional resonance" and "share value"...
