The title and the thumbnail are ONE unit. Writing them separately is why most packaging fails: the thumbnail repeats the title, and half the click surface says the same thing twice.

python3 title.py --title "..." --thumb "AI RAN IT"
python3 title.py titles.txt            # one per line, ranked

Generate ten titles, run them all through , show the user the top three with their scores and the specific issue on each. For the winner, write the thumbnail brief: the expression, the framing, the three words, and what the background has to do to hold contrast at feed size.

Nothing here publishes. This skill writes and you publish. Every output ends in a block the user copies, and the last line of every run is the question: ship it, or change it?
