What it does

This prompt instructs an image model to create an epic, cinematic digital artwork of a surreal cosmic chessboard at the instant of checkmate, featuring a radiant cracked king and exploding pieces turning into constellations amid nebula clouds and dramatic blue‑gold lighting. The key outcome is a hooded, galaxy-forged reaper figure whose face is identity-locked to match the uploaded selfie with realistic proportions and recognizable features, while their body, hood, and reaching hand transform into starfields, dust, and constellation-like light trails. It also enforces strict realism constraints to prevent facial distortion, duplicate faces, or anatomical errors (like extra fingers) while maintaining ultra-detailed, HDR, wide-angle, masterpiece-level rendering.

Inputs

textInputs

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

Variable key	Required?	Description	Defaults
test	Required		(none)

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-path <path>

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:
  • test
• 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 any required text input or 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 \
  [--input <key>=<value>] \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• Pass each image using --image-input-url 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 \
  --input test=<value> \
  --image-input-url https://example.com/image1.png \
  --model gemini-3-pro-image-preview \
  --options '{"aspectRatio":"1:1","resolution":"1K"}'
