What it does
This prompt instructs an image model to generate a vertical, three-panel Christmas-themed selfie portrait featuring the same subject in all panels, with consistent cozy indoor lighting and a festive background of decorated trees and gifts. It specifies arm’s-length, medium close-up framing and three slightly different casual poses and expressions to create candid holiday variety while keeping the overall look warm and authentic. The key outcome is a cohesive triptych that preserves the subject’s identity exactly—maintaining natural facial features, skin texture, hair, age, and gender expression—without any beautification or stylized 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 | 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 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-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":"3:4","resolution":"1K"}. - If the human does not specify, defaults are used: model
gemini-3-pro-image-preview, options{"aspectRatio":"3:4","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 (Your photo)".
Step 2: Run via BetterPrompt CLI
Use the frontmatter's name as the positional argument (for this skill, use cozy-christmas-selfie).
Command form:
betterprompt generate cozy-christmas-selfie \
[--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":"3:4","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 cozy-christmas-selfie \
--image-input-url https://example.com/image1.png \
--model gemini-3-pro-image-preview \
--options '{"aspectRatio":"3:4","resolution":"1K"}'
