Summary
This generates YouTube thumbnails optimized for click-through rate using the muapi image API. You feed it your video title, optionally describe a subject or face to feature, and it produces a 16:9 image with high contrast and bold composition. The skill intentionally avoids baking text into the AI-generated image (since model text rendering is unreliable) and instead gives you placement and font recommendations for adding the overlay yourself in Canva or Photoshop. It follows the proven thumbnail formula of emotion-first subjects, rule-of-thirds layout, and oversaturated colors that pop in the YouTube grid. Useful if you're publishing regularly and need a structured starting point instead of guessing at prompts.
