Universal Character Creator

What it does

This prompt guides an AI image model to generate a hyper-realistic, cinematic studio portrait of a human character using user-specified traits (e.g., nationality/ethnicity, gender identity, age, framing, expression, and outfit), producing a natural, professionally lit casting-photo look. It enforces a softly lit warm off-white background, centered composition, accurate anatomy, and subtle emotional expression while prohibiting text, logos, props, stylization, fantasy elements, and unsafe or controversial content, resulting in a clean, timeless 4K portrait aligned to strict realism and safety constraints.

Inputs

textInputs

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

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:

• Optional text inputs (use defaults if not provided by the human):
  • age (default: middle-aged)
  • gender (default: male/female)
  • outfit (default: casual shirt and jeans)
  • framing (default: front-facing portrait)
  • expression (default: slightly smiling)
  • nationality (default: Indian)
• Optional: model and options.
  • Present the human with the default model gemini-2.5-flash-image-preview and its available options. Look up gemini-2.5-flash-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: {}.
  • If the human does not specify, defaults are used: model gemini-2.5-flash-image-preview, options {}. Other models from the resources call are also available.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use universal-character-creator).

Command form:

betterprompt generate universal-character-creator \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gemini-2.5-flash-image-preview.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {}.
• 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 universal-character-creator \
  --input age=middle-aged \
  --input gender=male/female \
  --input 'outfit=casual shirt and jeans' \
  --input 'framing=front-facing portrait' \
  --input 'expression=slightly smiling' \
  --input nationality=Indian \
  --model gemini-2.5-flash-image-preview \
  --options '{}'
