book-cover-design
by inferen-shAI-supported book cover design skill focused on genre conventions, typography, sizing, and iteration. Helps you create fiction and non-fiction covers, test thumbnails, and generate concepts via inference.sh CLI. Ideal for self-publishing authors, small presses, designers, and marketers producing ebook, print, audiobook, and mockup covers.
Overview
What the book-cover-design skill does
The book-cover-design skill helps you plan and generate genre-appropriate book covers using AI image generation via the inference.sh (infsh) CLI. It combines:
- Genre-specific visual conventions for fiction and non-fiction
- Practical typography rules for titles, subtitles, and author names
- Guidance on aspect ratios, sizing, and thumbnail performance
- Iteration workflows for AI-generated cover concepts
Instead of guessing what “looks like” a thriller, romance, or business book, this skill gives your agent a structured set of expectations, then uses AI to produce visual directions you can refine into final covers.
Who this skill is for
This skill is a good fit if you are:
- Self-publishing authors who need compelling covers for Kindle, Kobo, and print-on-demand
- Small publishers or indie presses standardizing cover quality across multiple titles
- Designers and marketers using AI images as starting points for professional layouts
- Product teams prototyping cover directions for pitches, mockups, or landing pages
What problems it solves
The book-cover-design skill is designed to solve common cover problems:
- Covers that don’t match genre conventions and confuse readers
- Beautiful art that fails as a thumbnail on retailer grids
- Inconsistent typography that looks amateurish or off-brand
- Slow trial-and-error when briefing AI models for cover concepts
By encoding genre rules and layout expectations into an agent workflow, it speeds up the path from idea to usable cover concepts.
When book-cover-design is (and isn’t) a good fit
Use the book-cover-design skill when:
- You already use or are willing to install the inference.sh CLI (
infsh) - You want AI-assisted visual exploration before final design and typesetting
- You need fast, iterative cover concepts for fiction and non-fiction titles
It may not be the best fit when:
- You cannot run CLI tools or Bash-based workflows
- You need a full production-ready InDesign/Photoshop layout end-to-end (this skill focuses on concept generation and design direction, not final print-prep files)
- Your workflow explicitly forbids AI-generated imagery
If you mainly need brand strategy or copywriting for blurbs, look at other branding or writing-focused skills and treat book-cover-design as a visual asset companion.
How to Use
1. Prerequisites and installation
The book-cover-design skill relies on the inference.sh CLI for AI image generation.
- Install the skill into your agent environment:
npx skills add https://github.com/inferen-sh/skills --skill book-cover-design - Install and configure
infsh(required for image generation). Follow the official CLI install guide from the repository:https://raw.githubusercontent.com/inference-sh/skills/refs/heads/main/cli-install.md
- Authenticate with inference.sh once installation is complete:
infsh login
The skill is configured to use *Bash (infsh ) as its allowed tool, so ensure your runtime can execute Bash commands.
2. Core workflow: generate a first cover concept
Once installed and logged in, you can generate a first concept using the same pattern shown in the skill guide:
infsh app run falai/flux-dev-lora --input '{
"prompt": "dark moody book cover art, lone figure standing at end of a rain-soaked alley, dramatic chiaroscuro lighting, noir atmosphere, cinematic, high contrast shadows",
"width": 832,
"height": 1248
}'
``
Adapt this pattern by:
- Updating the **prompt** to describe your book’s genre, setting, main motif, and mood
- Adjusting **width/height** to match your preferred aspect ratio (e.g., typical ebook cover proportions)
- Running multiple variations and saving the best results for layout testing
Your agent will use the book-cover-design conventions to keep prompts and decisions aligned with reader expectations.
### 3. Follow the skill documentation in SKILL.md
After installation, open the skill’s primary guide:
- `SKILL.md` – main description, conventions, and workflow
This file explains how book-cover-design structures decisions around:
- **Genre Conventions** – palettes, imagery, typography, and mood for multiple fiction genres
- **Fiction vs. Non-Fiction** – how expectations differ and what to prioritize visually
- **Sizing and thumbnails** – guidance on designing covers to stay legible in small retailer listings
- **Iteration workflows** – how to cycle through prompts, refine concepts, and select strong options
Use these rules to brief your agent: describe your book, target genre, and format (ebook/print/audiobook), then let the skill suggest prompt directions and layout ideas.
### 4. Integrate with your own repo and tools
The book-cover-design skill is intended to be **adapted**, not copied blindly. For a robust setup:
1. Clone or reference the `inferen-sh/skills` repository to see how book-cover-design is organized under:
- `guides/design/book-cover-design`
2. Keep your **project-specific prompts** and cover decisions in your own repo (for example under `design/book-covers/`), while using book-cover-design as the rules engine.
3. Use a script or task runner to wrap common `infsh` invocations, so you can:
- Regenerate covers when metadata changes
- Batch-generate concepts for a whole series
This approach lets you preserve **version control** over prompts, covers, and design decisions while relying on the shared skill for best practices.
### 5. Typical use cases and patterns
Here are common ways teams use the book-cover-design skill:
#### Self-published fiction series
- Define core series visual rules (palette, typography style, recurring motif)
- Use book-cover-design’s **genre tables** to lock in conventions (e.g., thriller vs. cozy mystery)
- Generate a set of AI concepts for each book and choose 1–2 for professional refinement
#### Non-fiction business or self-help
- Emphasize **clear title hierarchy** and bold typography
- Use AI mostly for **background texture or simple iconography**
- Test multiple colorways quickly via `infsh` prompts, then pick the most legible thumbnail
#### Audiobook and format variants
- Start from the same visual concept
- Adjust canvas size and composition (via `width`/`height` and prompt tweaks)
- Use the skill’s sizing guidance to keep **title and author readable** on square or near-square audiobook artwork

## FAQ
### How do I install the book-cover-design skill?
Install book-cover-design via the `skills` CLI:
```bash
npx skills add https://github.com/inferen-sh/skills --skill book-cover-design
Then install and log into the inference.sh CLI so the skill can run AI image generation:
# Follow CLI install guide from the repo, then
infsh login
What tools does book-cover-design require?
The skill is configured with:
- Allowed tool:
Bash(infsh *)
That means your environment must support Bash and the inference.sh (infsh) CLI. Without infsh, the skill can still provide design guidance conceptually, but it cannot execute image generation commands.
Can I use book-cover-design for both fiction and non-fiction?
Yes. The skill’s description explicitly covers fiction and non-fiction and includes guidance on genre conventions for various fiction categories as well as non-fiction expectations (clean layouts, strong title hierarchy, etc.). Use the genre sections in SKILL.md to brief your agent based on your specific book type.
Does this skill produce print-ready covers?
Not by itself. book-cover-design focuses on:
- AI-generated cover concepts and visual directions
- Genre alignment, layout ideas, and typography guidance
You will typically:
- Generate concepts via
infshusing the patterns shown in the skill. - Export chosen art into a design tool (e.g., Photoshop, Affinity, Figma, InDesign) for:
- Final layout and typography
- Spine/back cover assembly
- Print-ready export to your printer’s specifications
Can I customize prompts and aspect ratios?
Yes. The example infsh app run command is only a starting point. You should:
- Tailor the prompt to your book’s specific setting, character focus, and mood
- Adjust
widthandheightto suit ebook, print, or audiobook formats you are targeting - Run multiple variations while keeping genre rules from book-cover-design in mind
Is book-cover-design suitable if I don’t want any AI images?
You can still use the genre, layout, and typography guidance as a design reference, but the workflow is optimized around AI image generation via infsh. If you do not want AI imagery at all, treat the skill as a structured checklist and rely on your human designer for the artwork.
Where can I see the underlying documentation?
