What it does

This prompt instructs an AI to produce a minimalist, Excalidraw-style architecture diagram for a specified system, choosing an appropriate 16:9 horizontal or vertical layout and organizing the design into clearly labeled modules with their key functions. It requires clean box-and-arrow visuals on a white background, uses arrows for primary data/process flows and dashed lines for auxiliary or supervisory relationships, and allows limited red highlights to emphasize important lines or labels, resulting in a professional technical sketch that communicates the system’s structure and interactions.

Inputs

textInputs

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

Variable key	Required?	Description	Defaults
architecture_name	Required		(none)

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:
  • architecture_name
• 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":"5:4","resolution":"1K"}.
  • If the human does not specify, defaults are used: model gemini-3-pro-image-preview, options {"aspectRatio":"5:4","resolution":"1K"}. 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 excalidraw-style-architecture-diagram).

Command form:

betterprompt generate excalidraw-style-architecture-diagram \
  [--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":"5:4","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 excalidraw-style-architecture-diagram \
  --input architecture_name=<value> \
  --model gemini-3-pro-image-preview \
  --options '{"aspectRatio":"5:4","resolution":"1K"}'
