# Object Eraser

> This prompt instructs an AI photo-editing assistant to remove a user-specified unwanted object from an uploaded image and convincingly inpaint the missing area so the background continues naturally. It emphasizes preserving everything else in the photo—especially the main subject—while matching lighting, shadows, texture, and perspective to avoid visible artifacts. The outcome is a clean, realistic image where the removed item leaves no trace and the scene looks unchanged apart from that deletion.

## What it does

This prompt instructs an AI photo-editing assistant to remove a user-specified unwanted object from an uploaded image and convincingly inpaint the missing area so the background continues naturally. It emphasizes preserving everything else in the photo—especially the main subject—while matching lighting, shadows, texture, and perspective to avoid visible artifacts. The outcome is a clean, realistic image where the removed item leaves no trace and the scene looks unchanged apart from that deletion.

## Inputs


### textInputs

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

| Variable key | Required? | Description | Defaults |
| --- | ---: | --- | --- |
| `background_type` | Optional | The type of background to fill the removed area. | `auto → AI automatically continues the background.` |
| `object_to_remove` | Optional | The specific object you want to delete from the photo. | `the person in a red shirt in the background` |



### 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 | Insert image you want to remove objects | `--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:

- Optional text inputs (use defaults if not provided by the human):
    - `background_type` (default: `auto → AI automatically continues the background.`)
  - `object_to_remove` (default: `the person in a red shirt in the background`)
- Required images:
  - **Exactly 1** images: image 1 (Insert image you want to remove objects). 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 (Insert image you want to remove objects)"**.

### Step 2: Run via BetterPrompt CLI

Use the frontmatter's `name` as the positional argument (for this skill, use `object-eraser`).

Command form:

```bash
betterprompt generate object-eraser \
  [--input <key>=<value>] \
  [--image-input-url <url>] \
  [--image-input-path <path>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]
```

Notes:

- Pass each text input as a separate `--input <key>=<value>` flag.
- 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 object-eraser \
  --input 'background_type=auto → AI automatically continues the background.' \
  --input 'object_to_remove=the person in a red shirt in the background' \
  --image-input-url https://example.com/image1.png \
  --model gemini-2.5-flash-image-preview \
  --options '{}'
```
