29User: I need a YouTube thumbnail for "5 Python Mistakes"
30Agent: Design brief: **Dimensions:** 1280x720px. **Layout:** Split — left 60% face with shocked expression, right 40% code snippet with red error highlight. **Text:** "5 MISTAKES" in bold Impact font, yellow with black outline. **Colors:** Dark background (#1a1a2e), yellow accent (#e6c229), red error (#e63946). **Elements:** Large "5" number overlay, subtle Python logo. **Why this works:** Face + number + contrast is the top-performing YouTube thumbnail pattern (avg 8.2% CTR vs 4.1% text-only).

32User: My blog thumbnails get low engagement
33Agent: Analyzed your last 20 thumbnails. Issues: 1) Text too small — unreadable on mobile (60% of traffic). 2) Muted colors blend with feed. 3) No human element. Fixes: 1) Max 4 words, minimum 48px font. 2) Use contrasting background (#FF6B35 orange or #2EC4B6 teal). 3) Add an avatar or illustrated character. Expected CTR improvement: 30-50%.
