mirror-message-cinematic-bathroom-thriller

What it does

This prompt instructs an image generator to create a photorealistic, tense cinematic bathroom scene using an uploaded portrait as the main subject, dressed in a simple school-uniform outfit, framed through a dirty mirror under harsh fluorescent lighting. The resulting image is a medium, shallow–depth-of-field photograph where the subject’s reflection and the red lipstick message on the mirror are sharp, while a menacing Joker figure appears behind them in the mirror slightly out of focus, with strict constraints to preserve realism, coherent reflections/lighting, and exclude extra text, logos, or stylized rendering.

Requires the betterprompt CLI to run. For installation and general CLI usage, refer to the betterprompt skill in your skill list or if not yet available in skill list, install via npx skills add https://github.com/BetterPromptme/betterprompt/skills --skill betterprompt

Inputs

textInputs

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

imageInputs

This prompt requires exactly 1 image. You must pass exactly 1 image flag (no more, no fewer), in the order matching the descriptions below.

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):
  • outfit (default: white button-down shirt, rolled sleeves, dark red striped tie, grey pleated skirt” or “white shirt with rolled sleeves, dark red striped tie, charcoal trousers,...)
• Required images:
  • Exactly 1 images: image 1 (Upload one clear portrait photo of the subject.). Images must be provided in this order.
• 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.

If the required images are missing, ask the human for what's missing. Do not assume or fabricate values. Tell the human: "Please provide images in this order: image 1 (Upload one clear portrait photo of the subject.)".

Step 2: Run via BetterPrompt CLI

Use the frontmatter's skillVersionId as the positional argument (for this skill version, use 019a0a98-9642-77cf-8774-07c2797b33bd).

Command form:

betterprompt generate 019a0a98-9642-77cf-8774-07c2797b33bd \
  [--input <key>=<value>] \
  [--image-input-url <url>] \
  [--image-input-base64 <base64>] \
  [--image-input-path <absolute path to image>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• Pass each image using one of --image-input-url, --image-input-base64, or --image-input-path, in the order matching the imageInputs descriptions (image 1 first, then image 2, etc.).
• 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 019a0a98-9642-77cf-8774-07c2797b33bd \
  --input 'outfit=white button-down shirt, rolled sleeves, dark red striped tie, grey pleated skirt” or “white shirt with rolled sleeves, dark red striped tie, charcoal trousers,...' \
  --image-input-url https://example.com/image1.png \
  --model gemini-2.5-flash-image-preview \
  --options '{}'
