Spectral Aura Style

What it does

This prompt directs an image generator to depict a chosen subject as a spectral diffraction-style portrait, emphasizing prismatic light separation and chromatic edge fringing in two specified colors. The intended result is an ethereal, crystal-like aura with visible rainbow banding and distorted edges that heighten the sense of refracted light.

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:

• Required text inputs:
  • color1
  • color2
  • SUBJECT
• Optional: model and options.
  • Present the human with the default model gpt-image-1 and its available options. Look up gpt-image-1 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: {"quality":"medium"}.
  • If the human does not specify, defaults are used: model gpt-image-1, options {"quality":"medium"}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use spectral-aura-style).

Command form:

betterprompt generate spectral-aura-style \
  [--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: gpt-image-1.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {"quality":"medium"}.
• 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 spectral-aura-style \
  --input color1=<value> \
  --input color2=<value> \
  --input SUBJECT=<value> \
  --model gpt-image-1 \
  --options '{"quality":"medium"}'
