What it does
This prompt instructs an AI image compositor to recreate the official mystery ensemble poster’s exact composition, environment, perspective, lighting, and all supporting characters unchanged, while swapping only the central squatting figure with the provided person from the input photo. The expected outcome is a poster-grade, photorealistic composite where the inserted subject matches the original pose, scale, and cinematic color grading and blends seamlessly into the locked layout, with the subject’s face identity preserved exactly without any alteration.

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 | Upload your photo (portrait photo is recommended) | --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 images:
- Exactly 1 images: image 1 (Upload your photo (portrait photo is recommended)). Images must be provided in this order.
- Optional: model and options.
- Present the human with the default model
gemini-3-pro-image-previewand its available options. Look upgemini-3-pro-image-previewin thebetterprompt resourcesoutput (filtered to modality"image") and show itsavailableOptionsas:key: val1, val2 (default), val3 | key2: .... Mark a value(default)if it matches these defaults:{"aspectRatio":"4:3","resolution":"1K"}. - If the human does not specify, defaults are used: model
gemini-3-pro-image-preview, options{"aspectRatio":"4:3","resolution":"1K"}. Other models from the resources call are also available.
- Present the human with the default model
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 (Upload your photo (portrait photo is recommended))".
Step 2: Run via BetterPrompt CLI
Use the frontmatter's name as the positional argument (for this skill, use wake-up-dead-man-poster).
Command form:
betterprompt generate wake-up-dead-man-poster \
[--image-input-url <url>] \
[--image-input-path <path>] \
[--model <model>] \
[--options <options JSON>] \
[--json]
Notes:
- Pass each image using
--image-input-urlor--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
--modeland BetterPrompt will use the default model:gemini-3-pro-image-preview. - If the human does not mention options, omit
--optionsand BetterPrompt will use the default options:{"aspectRatio":"4:3","resolution":"1K"}. - If the run times out, the response will include a
runIdyou can use to fetch the result later.
Example (using defaults shown above):
betterprompt generate wake-up-dead-man-poster \
--image-input-url https://example.com/image1.png \
--model gemini-3-pro-image-preview \
--options '{"aspectRatio":"4:3","resolution":"1K"}'
