YouTube thumbnail generation for high CTR

genai

YouTube thumbnail generation for high CTR is a Claude Code skill that generates click-worthy YouTube thumbnails via the AI SKILLS connector (aiskills.team/mcp). It starts by proposing 2–3 thumbnail concepts — each with a focal object, emotion, text overlay, and color palette — then produces 1–2 variants per concept using `generate_image` at 16:9 aspect ratio. CTR rules are baked in: a single visual center readable at 120 px, a face showing shock, joy, or skepticism, and a bold text overlay of no more than 4 words with a contrasting outline or background. When the user supplies a photo of the host, the skill runs image-to-image to keep the face recognizable. The best text-rendering model is selected from `list_models` (e.g. GPT Image, Nano Banana), and a set of 4–6 variants typically costs under $1 — with a cost estimate provided before generation begins.
