What it does

Generates a museum-quality, 1890s-inspired patent technical illustration of the specified object, rendered as black-ink linework with sepia accents on aged cream parchment. The result includes hand-lettered labels, numbered component callouts, cross-section views, and an official-looking patent border with a fictional patent number and date, producing an elegant, authoritative vintage engineering drawing.

Inputs

textInputs

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

Variable key	Required?	Description	Defaults
object	Optional		a complex mechanical device

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):
  • object (default: a complex mechanical device)
• 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":"1:1","resolution":"1K"}.
  • If the human does not specify, defaults are used: model gemini-3-pro-image-preview, options {"aspectRatio":"1:1","resolution":"1K"}. 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 vintage-patent-drawing-with-nano-banana-pro-in-openart).

Command form:

betterprompt generate vintage-patent-drawing-with-nano-banana-pro-in-openart \
  [--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-3-pro-image-preview.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {"aspectRatio":"1:1","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 vintage-patent-drawing-with-nano-banana-pro-in-openart \
  --input 'object=a complex mechanical device' \
  --model gemini-3-pro-image-preview \
  --options '{"aspectRatio":"1:1","resolution":"1K"}'
