story-cover — Web Novel Cover Generator

Give it a book title and pen name, and it infers the genre and generates a professional web-novel cover with the title and author name rendered in.

What it does

Infers genre from title keywords using a built-in rule table and priority order (xianxia > western fantasy > historical romance > modern romance > urban > mystery > sci-fi > history > horror > light novel).
Assembles an English prompt in three layers: text (title typography + a deliberately designed author-name style with ornaments), platform style, and artwork (character, background, lighting).
Prefers Codex CLI's built-in ImageGen; falls back to the GPT-Image API via curl/jq/base64 only when needed. If a reference image is supplied it switches to the images/edits image-to-image path.
Saves auto-incrementing versions (封面_v1.png, v2, …) plus a matching .prompt.txt so you can iterate on the last prompt.
When the platform has fixed upload pixels (e.g. 600×800 for Fanqie), it center-crops and scales with ImageMagick or macOS sips so the title and byline never get clipped.

Who it's for

Web novel and self-published ebook authors who have to make their own covers.
Solo publishers who want several cover concepts fast without hiring a designer.
Anyone who wants image-generation prompts managed as reusable, structured templates.

Examples

"Cover for 'Sword Sovereign of Nine Heavens' by Qingyun, for Fanqie" → detects xianxia, gold brush-calligraphy title, cloud-scroll byline, 3:4 output plus a 600×800 upload copy.
"Give me three modern-romance cover options" → generates layout A (character close-up), B (full-body dynamic pose), and C (pure scenery) for comparison.
Set REF_IMAGE to an existing illustration → the skill uses image-to-image editing to keep the art style and only add the title and pen name.

Install in Claude Code

Let Claude do it — paste this into Claude Code

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

Install with a command instead

git clone https://github.com/zenstory-ai/oh-story-claudecode.git /tmp/oh-story && mkdir -p ~/.claude/skills && cp -r /tmp/oh-story/skills/story-cover ~/.claude/skills/

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

Open a terminal.
Clone the repo: git clone https://github.com/zenstory-ai/oh-story-claudecode.git
Copy the skill: mkdir -p ~/.claude/skills && cp -r oh-story-claudecode/skills/story-cover ~/.claude/skills/
Make sure curl, jq, and base64 are installed (plus magick/convert, or macOS sips, for the crop step).
If you are not using Codex CLI's built-in ImageGen, set your key: export GPT_IMAGE_API_KEY=your_key (add export GPT_IMAGE_BASE_URL=... for a compatible proxy).
Restart Claude Code, then run /story-cover or ask "make me a novel cover" and provide the title, pen name, target platform, and output folder (./covers/<title>).
