name: eternitys-checkmate description: This prompt directs the AI to generate an ultra-detailed, cinematic digital artwork of a colossal cosmic chessboard at the moment of checkmate, featuring a cracked, radiant king and shattered pieces turning into constellations amid nebula clouds and dramatic volumetric lighting. It requires the hooded “cosmic reaper” figure to retain the uploaded selfie subject’s natural, recognizable facial identity (realistic proportions and features) while transforming their body and attire into galaxy-forged materials, with a reaching hand partially becoming constellation light trails. The intended outcome is a wide-angle, dark blue-and-gold, HDR, 8K scene that preserves the person’s likeness without distortions, extra fingers, or duplicate faces, blending cinematic realism with surreal cosmic symbolism. compatibility: Requires betterprompt >= 0.1.0

What it does

This prompt directs the AI to generate an ultra-detailed, cinematic digital artwork of a colossal cosmic chessboard at the moment of checkmate, featuring a cracked, radiant king and shattered pieces turning into constellations amid nebula clouds and dramatic volumetric lighting. It requires the hooded “cosmic reaper” figure to retain the uploaded selfie subject’s natural, recognizable facial identity (realistic proportions and features) while transforming their body and attire into galaxy-forged materials, with a reaching hand partially becoming constellation light trails.

Inputs

imageInputs

This prompt requires exactly 1 image. You must pass exactly 1 image flag (no more, no fewer), in the order matching the descriptions below.

Index	Required	Description	Allowed CLI flags
1	Yes	Your photo	--image-input-url <url> or --image-input-base64 <base64> or --image-input-path <absolute path to image>

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 images:
  • Exactly 1 images: image 1 (Your photo). Images must be provided in this order.
• Optional: model and options.
  • Present the human with the default model gemini-3-pro-image-preview and its available options. Look up gemini-3-pro-image-preview 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: {"aspectRatio":"1:1","resolution":"1K"}.
  • If the human does not specify, defaults are used: model gemini-3-pro-image-preview, options {"aspectRatio":"1:1","resolution":"1K"}. Other models from the resources call are also available.

If the required images are missing, ask the human for what's missing. Do not assume or fabricate values. Tell the human: "Please provide images in this order: image 1 (Your photo)".

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use eternitys-checkmate).

Command form:

betterprompt generate eternitys-checkmate \
  [--image-input-url <url>] \
  [--image-input-base64 <base64>] \
  [--image-input-path <absolute path to image>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each image using one of --image-input-url, --image-input-base64, or --image-input-path, in the order matching the imageInputs descriptions (image 1 first, then image 2, etc.).
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gemini-3-pro-image-preview.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {"aspectRatio":"1:1","resolution":"1K"}.
• 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 eternitys-checkmate \
  --image-input-url https://example.com/image1.png \
  --model gemini-3-pro-image-preview \
  --options '{"aspectRatio":"1:1","resolution":"1K"}'
