Bestie Car Selfie

What it does

This prompt instructs an image-generation/editing model to combine two separate reference photos into a single realistic, influencer-style “bestie” selfie of two female friends sitting close together inside a modern car, explicitly assigning the first input to the left subject and the second input to the right subject. It emphasizes strict identity preservation (no blending, no changes to facial structure, ethnicity, or age), adds light natural beauty retouching and trendy styling/accessories, and specifies a front-camera selfie composition with bright daytime natural light, soft warm tones, subtle realism-enhancing texture, and no text or watermarks, resulting in a polished but believable photograph.

Inputs

imageInputs

This prompt requires exactly 2 images. You must pass exactly 2 image flags (no more, no fewer), in the order matching the descriptions below.

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 2 images: image 1 (The exact identity reference for the left girl) and image 2 (The exact identity reference for the right girl). 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":"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.

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 (The exact identity reference for the left girl) and image 2 (The exact identity reference for the right girl)".

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use bestie-car-selfie).

Command form:

betterprompt generate bestie-car-selfie \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• 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":"3:4","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 bestie-car-selfie \
  --image-input-url https://example.com/image1.png \
  --image-input-path /path/to/image2.png \
  --model gemini-3-pro-image-preview \
  --options '{"aspectRatio":"3:4","resolution":"1K"}'
