Cover Strategy
The competitive shelf position for this cover.
Dark Romance · "The Gilded Cage"

Visual promise: danger wrapped in opulence — not a love story, a power struggle. The comp covers (Penelope Douglas, Ana Huang) rely on illustrated couples in warm golds. This cover differentiates by removing the couple entirely: one gilded birdcage, cracked open, a single dark feather falling.

Genre signal is immediate at thumbnail. The single object reads clearly at 72px. Differentiation is strong without leaving the genre.
Shelf analysis + comp study + one-visual-promise — written before a single pixel is designed.
AI Generation Prompt
Paste directly into Midjourney or DALL-E.
Primary prompt:
Book cover design for dark romance novel, ornate gilded birdcage cracked open, single dark feather falling, deep jewel-tone background in midnight navy and antique gold, painterly illustration style with visible brushstrokes, dramatic uplighting from below, rich texture and impasto finish, no text, portrait orientation — --ar 2:3 --v 6

Negative: stock photo couple, bokeh blur, photorealistic, sunrise, generic flowers, white background, cartoon
Tool recommendation, variation directions, and Ideogram v3 alternative included.
Design System
Colour palette and typography — fully specified.
Dominant: Midnight Navy #0d1b2a
Secondary: Antique Gold #c9a84c
Accent: Aged Ivory #f2e8d9
Dark anchor:Void Black #050a0f
Title face: Cinzel Decorative · Bold · +40 tracking
Author name: EB Garamond · Regular · bottom centre
Max 2 font families. Title legible at 150px. Named Google Fonts fallbacks included.
Title Treatment
How the type sits inside the scene.
Title in Cinzel Decorative Bold fills the upper 30% of the cover, set in Aged Ivory (#f2e8d9). Letters sit slightly behind the top bars of the cage — a 3px feathered mask creates a depth illusion without full integration.

Author name in EB Garamond, one-third the visual weight of the title, bottom 8%, centred, same ivory — sufficient contrast against the dark navy field.

Safe zone: all text within 18px of edge. No text element within 0.25″ of trim on print wrap.
Full integration style, spine rules, and back-cover layout included for paperback format.

How it works

How does Book Cover Prompt work?

  1. Tell Claude what you need — the skill asks 2-3 narrowing questions specific to the task.
  2. The skill runs live research and structures the output before writing a single word.
  3. An anti-slop quality gate checks the draft, then delivers a ready-to-use result for $5.

Not what this is for
✕Traditionally published authors — cover decisions belong to the publisher.
✕Final production files — it outputs the brief and prompt, not the finished image.
✕Non-book design projects — it's calibrated specifically to book cover shelf dynamics.

The complete guide to book cover briefs covers what makes a cover that works before the title is read versus a decorative one.

"I've published four books and never had a cover brief this detailed. The AI prompt alone got me a result I'd have paid a designer $400 for."

Quick answers

Do I need a paid Claude account for Book Cover Prompt?

No. The free Claude plan is enough to get started and see the skill working. A Pro plan unlocks longer outputs.

How do I install the Book Cover Prompt skill?

Download the .skill file, open Claude, go to Customize → Skills → Upload a skill, and drop the file in. It appears in your slash-command list immediately.

Can I edit or customise the output after I receive it?

Yes. The output is plain text you own and can edit freely. Most users tweak specific details or the call-to-action to fit their exact use case before sending or publishing.

How specific do my inputs need to be to get a good result?

The more specific your input, the more precise the output. The skill asks targeted questions to gather context — answering these in detail produces noticeably better results than generic one-line inputs.
