thumbnail-ultrathink

YouTube employee · Assisted thumbnail judgment for choosing a high-impact visual story before rendering. Deconstructs relevant references, creates three materially different thumbnail visual stories, rejects objectively weak concepts, explains close calls, records the human's selection and reason, and produces a renderer-neutral concept brief. USE WHEN the user says 'analyze this thumbnail', 'why does this thumbnail work', 'thumbnail ideas', 'three thumbnail visual stories', 'choose a thumbnail concept', 'design a thumbnail concept', 'whiteboard thumbnail', 'visual metaphor', or needs a thumbnail that communicates in one second. Do NOT use for a complete YouTube production package (youtube-strategy), image rendering alone, or post-publish analytics.
