name: universal-character-creator description: 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. compatibility: Requires betterprompt >= 0.1.3 metadata: openclaw: homepage: https://github.com/BetterPromptme/skills emoji: 🧩 requires: anyBins: - betterprompt - bp os: - linux - darwin install: - id: node kind: node package: betterprompt bins: [betterprompt, bp] label: Install BetterPrompt CLI (node)

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.

Variable key	Required?	Description	Defaults
age	Optional	Describe the approximate age of the character.	middle-aged
gender	Optional	Specify the gender identity of the character.	male/female
outfit	Optional	Describe the character’s outfit or clothing tone	casual shirt and jeans

nationality	Optional	Specify the nationality or ethnicity of the character.	Indian

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 '{}'
