description: YouTube Thumbnail (Open Design) — use only when explicitly invoked, not for general design requests

<!-- generated:open-design-agent-kit -->
Use the Open Design skill `od:prototype:social-youtube-thumbnail` (YouTube Thumbnail).
Treat the rest of the user's message as the brief. If nothing more specific was given, use: "Use the YouTube Thumbnail template to design a thumbnail for my video. Make the promise of the video readable in under a second: one short hook line, one strong focal subject, high contrast. Use real content from my brief and avoid lorem ipsum or placeholder images."
Call `prepare_open_design_brief` (the open-design MCP server's tool) with skillId "od:prototype:social-youtube-thumbnail" and this brief — call `list_open_design_design_systems` first only if the user names a brand or visual direction. Author the files yourself with your own file-editing tools per the returned instructions, then call `register_open_design_artifact`.
