What it does

This prompt instructs an AI to generate a visually striking 3D book cover concept tailored to a specified title, genre, and author, emphasizing imaginative symbolism, bold cinematic color and lighting, expressive typography, and an intriguing metaphorical focal element. The expected outcome is an iconic, modern, intellectually engaging cover design that feels emotionally impactful and commercially compelling, suitable for a bestselling book.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Variable key	Required?	Description	Defaults
GENRE	Required		(none)
BOOK_TITLE	Required		(none)
AUTHOR_NAME	Required		(none)

Models and options

This skill's modality is: image.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "image".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "image" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Required text inputs:
  • GENRE
  • BOOK_TITLE
  • AUTHOR_NAME
• Optional: model and options.
  • Present the human with the default model gpt-image-1 and its available options. Look up gpt-image-1 in the betterprompt resources output (filtered to modality "image") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {"size":"1024x1024","quality":"low"}.
  • If the human does not specify, defaults are used: model gpt-image-1, options {"size":"1024x1024","quality":"low"}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use book-covers-without-a-designer-just-use-this-prompt).

Command form:

betterprompt generate book-covers-without-a-designer-just-use-this-prompt \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gpt-image-1.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {"size":"1024x1024","quality":"low"}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate book-covers-without-a-designer-just-use-this-prompt \
  --input GENRE=<value> \
  --input BOOK_TITLE=<value> \
  --input AUTHOR_NAME=<value> \
  --model gpt-image-1 \
  --options '{"size":"1024x1024","quality":"low"}'
