Use the Open Design skill od:prototype:social-carousel (social-carousel).

Treat the rest of the user's message as the brief. If nothing more specific was given, use: "Design a 3-card cinematic social carousel — ‘onwards.’, ‘to the next one.’, ‘looking ahead.’. 1080×1080 squares, drop-into-Instagram ready."

Call prepare_open_design_brief (the open-design MCP server's tool) with skillId "od:prototype:social-carousel" and this brief — call list_open_design_design_systems first if the user names a brand or visual direction, or recommend_open_design_design_systems if they name none and no design system is active. Author the files yourself with your own file-editing tools per the returned instructions, then call register_open_design_artifact.
