Use the Open Design skill od:deck:ppt-keynote (Keynote-style Slides).

Treat the rest of the user's message as the brief. If nothing more specific was given, use: "Use the Keynote-style Slides template to turn my content into Apple Keynote-quality slides with one card per screen and keyboard left/right navigation. Preserve the template's visual signature, use real content and data, and avoid lorem ipsum or placeholder images."

Call prepare_open_design_brief (the open-design MCP server's tool) with skillId "od:deck:ppt-keynote" 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.
