| description | Generate book cover art prompts for image generation models. Reads project content and produces optimized prompts for Kindle-dimension covers. |
Generate cover art prompts for your book using the cover-artist agent.
What This Does
- Asks whether you want image-only or text-inclusive covers
- Reads your project materials (README, themes, characters, world, tone)
- Synthesizes the story's visual essence
- Produces 3-5 distinct cover concepts as image generation prompts
- Optimizes for Kindle dimensions (2560 x 1600, aspect ratio 1.6:1)
Usage
/fiction:cover # Generate cover prompts for current project
/fiction:cover /path/to/project # Generate for specific project
Text Options
You'll be asked whether to include text:
- Image only (recommended) — Clean image with negative space for title overlay in post-production. More control over typography.
- Include text — Title and author name generated as part of the image. Works well with GPT Image 1.5 and Gemini 3 Pro.
Output
For each concept, you'll receive:
- Approach — The visual strategy
- Prompt — Ready to paste into Midjourney, DALL-E, or other generators
- Why it works — Genre signals and design rationale
- Variations — Style/mood alternatives
Generating Images
Once you have prompts, you can generate images with any AI image tool. If you have falcon installed, you can generate images directly from the command line:
falcon "your prompt here" --ar 5:8
Prompt Compatibility
Prompts are optimized for:
- Midjourney V7 — Use
--ar 5:8 for Kindle proportions
- DALL-E 3 — Specify dimensions in prompt
- Stable Diffusion — Works with standard prompt structure
- Other generators — Adapt aspect ratio parameters as needed
Design Philosophy
The agent prioritizes:
- Symbolic over literal — Evoke the feeling, don't illustrate the plot
- Cut-through — Stand out in crowded genre thumbnails
- Genre signals — Honor conventions while avoiding cliches
- Thumbnail test — Readable at 80px width
- Title space — Negative space in upper third for text overlay
After Generation
If you chose image-only:
- Generate images with your preferred AI tool (or falcon)
- Select the strongest result
- Add title and author name in a design tool (Canva, Photoshop, etc.)
- Test at thumbnail size
- Upload to KDP
If you chose text-inclusive:
- Generate images—inspect text carefully for errors
- Regenerate if any letters are wrong
- Minor touch-ups in design tool if needed
- Test at thumbnail size
- Upload to KDP
When to Use
- Final stages of manuscript completion
- Before submitting to beta readers (motivational)
- Marketing preparation
- Series branding exploration
