What it does
The most-installed media skill from Jim Liu (宝玉), a well-known Chinese AI writer whose baoyu-skills repo has 27K stars. It analyses an article, then builds a cover from five dimensions (type, palette, rendering, text, mood) that combine 11 color palettes and 7 rendering styles, in cinematic 2.35:1, 16:9 or 1:1. It writes every final prompt to a file before generating, prefers the runtime's native image tool (Codex imagegen, Cursor GenerateImage) or the pack's baoyu-image-gen backend, and refuses to fake raster output with SVG or to patch rendered text with overlays.
Use when
- Make a cover or header image for an article or post
- Iterate on a cover's palette, rendering or mood
Not for
- Diagrams, infographics or slide decks (the pack has separate skills)
