# Urban Frame Identity Lock

> This prompt instructs an image-generation workflow to create a vertical, photoreal 35mm film–style fashion editorial portrait set on a modern urban street, using a provided reference face and enforcing strict identity preservation. It defines wardrobe, pose, expression, framing, lighting, color palette, and film grain characteristics while prohibiting any changes to facial attributes, gender expression, hair, skin texture, or added makeup/logos/text. The intended outcome is a refined, natural-looking city editorial portrait with clear fine grain and balanced daylight contrast, and it halts to request a clearer reference image if the face is not adequately visible.

## What it does

This prompt instructs an image-generation workflow to create a vertical, photoreal 35mm film–style fashion editorial portrait set on a modern urban street, using a provided reference face and enforcing strict identity preservation. It defines wardrobe, pose, expression, framing, lighting, color palette, and film grain characteristics while prohibiting any changes to facial attributes, gender expression, hair, skin texture, or added makeup/logos/text. The intended outcome is a refined, natural-looking city editorial portrait with clear fine grain and balanced daylight contrast, and it halts to request a clearer reference image if the face is not adequately visible.

## Inputs



### 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.

| Index | Required | Description | Allowed CLI flags |
| ---: | ---: | --- | --- |
| 1 | Yes | A portrail photo | `--image-input-url <url>` or `--image-input-path <path>` |


### 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:

```bash
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:

```bash
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 images:
  - **Exactly 1** images: image 1 (A portrail photo). 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 (A portrail photo)"**.

### Step 2: Run via BetterPrompt CLI

Use the frontmatter's `name` as the positional argument (for this skill, use `urban-frame-identity-lock`).

Command form:

```bash
betterprompt generate urban-frame-identity-lock \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]
```

Notes:

- Pass each image using `--image-input-url` 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):

```bash
betterprompt generate urban-frame-identity-lock \
  --image-input-url https://example.com/image1.png \
  --model gemini-2.5-flash-image-preview \
  --options '{}'
```
