Baoyu Cover Image Generator

Designs and generates article cover images using a 5-dimension system of type, palette, rendering style, text level, and mood.

What it does

Analyzes your article, proposes a visual direction, writes the full prompt to a file, then calls an available raster backend to produce the cover.

  • Five dimensions: type (hero, conceptual, typography, metaphor, scene, minimal), 11 palettes, 7 rendering styles, 4 text levels, 3 mood levels, plus font choice
  • Aspect ratios: 16:9 (default), 2.35:1 cinematic, 1:1, 4:3, 3:2, 3:4
  • Reproducible: every prompt is saved to prompts/NN-*.md before generation, so you can swap backends without rewriting prompts
  • Reference images (--ref): extract style, composition, or character traits from samples
  • Guardrails: no SVG/HTML substitution for raster output, and no code-based text patching over a finished bitmap — bad text means a new prompt and a new file

Who it's for

  • Bloggers, newsletter authors, and technical writers who need thumbnails on every post
  • Solo creators and marketers who want a consistent brand look without a designer
  • Users already running Codex imagegen, Cursor GenerateImage, or the baoyu-image-gen skill

Examples

  1. Tech blog thumbnail: "make a cover for this post --type conceptual --palette cool --aspect 16:9"
  2. Cinematic newsletter header: "--aspect 2.35:1 --text title-only --mood bold" for a wide banner with the exact article title
  3. Series consistency: pin preferred_palette and preferred_rendering in EXTEND.md, then run with --quick so every article in a series shares one visual tone

Let Claude do it — paste this into Claude Code

Install the skill I found on Claude Skill Mart.
Copy the skills/baoyu-cover-image folder from the GitHub repo JimLiu/baoyu-skills into my ~/.claude/skills/baoyu-cover-image/.
When it's done, tell me in one line what this skill can do.

Install with a command instead

git clone https://github.com/JimLiu/baoyu-skills.git && mkdir -p ~/.claude/skills && cp -r baoyu-skills/skills/baoyu-cover-image ~/.claude/skills/

⚠ This is a third-party skill. Check the source repository before installing.

  1. Open a terminal in your working directory.
  2. Clone the repo: git clone https://github.com/JimLiu/baoyu-skills.git
  3. Copy the skill into place: mkdir -p ~/.claude/skills && cp -r baoyu-skills/skills/baoyu-cover-image ~/.claude/skills/
  4. (Recommended) Make sure a raster backend is available — Codex imagegen, Cursor GenerateImage, or install the sibling baoyu-image-gen skill from the same repo.
  5. Restart Claude Code and ask: "generate a cover image for this article".
  6. On the first run a setup wizard creates EXTEND.md; pick your default palette, aspect ratio, and image backend so later runs reuse them.
  7. Add --quick to any request to skip the confirmation step and generate immediately.
