Use it to create vintage engineering illustrations, mock patent documents, or technical artwork for mechanical objects.

It gives an image generator a fixed technical and historical style instead of requiring you to describe all those visual details each time.

Q: What is vintage-patent-drawing-with-nano-banana-pro-in-openart?

An image prompt for making an 1890s-style patent drawing of a specified object. It uses black ink, sepia accents, parchment, labels, numbered callouts, cross-sections, and a fictional patent border.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00092	$0.00938
Opus 5.5	$0.00037	$0.00375
Sonnet 5.5	$0.00018	$0.00188

Security

Grade A, and why

vintage-patent-drawing-with-nano-banana-pro-in-openart scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
