## What it does

This skill dispatches image synthesis tasks to the Linkfox API endpoint using `python scripts/multimodal_generate_image.py`. It creates visuals directly from prompts under 1000 characters, alters backgrounds, transfers art styles, and composites subjects into scenes. Supported aspect ratios include 1:1, 3:4, 4:3, 9:16, and 16:9.

You can pass up to three reference image links in the `referenceImageUrl` parameter. The tool requires publicly reachable URLs. If you work with local assets, run `python scripts/upload_image.py <path>` first to publish the file to a 24-hour temporary URL.

Without `LINKFOX_AGENT_API_KEY` or `LINKFOXAGENT_API_KEY` configured in your environment, calls fail with HTTP 401. Execution payloads write directly to `<cwd>/linkfox/...` in the project directory, while identical parameter calls resolve through a 24-hour local disk cache to prevent duplicate compute charges.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-generate-image -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/linkfox-multimodal-generate-image/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/linkfox-multimodal-generate-image/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-generate-image -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/linkfox-multimodal-generate-image/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-generate-image -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/linkfox-multimodal-generate-image/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install linkfox-ai/linkfox-skills linkfox-multimodal-generate-image
```

2. **Manually: put the files in place**

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-generate-image -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/linkfox-ai/linkfox-skills --path skills/linkfox-multimodal-generate-image
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/linkfox-multimodal-generate-image/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add linkfox-ai/linkfox-skills --skill linkfox-multimodal-generate-image -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/linkfox-ai/linkfox-skills/tree/HEAD/skills/linkfox-multimodal-generate-image/SKILL.md

## When to use it
- generate clean product shots from text descriptions
- change background colors or settings in an existing product frame
- composite an item from one reference image onto a surface in another
- swap human models or mannequins while preserving garment details
- upload local image files to public URLs before triggering the API

## Example prompts
- Generate a professional product photo of black wireless headphones on a blue background in 1:1 aspect ratio
- Replace the vase on the table in image 1 with a small potted plant
- Place the product from image 2 onto the marble countertop in image 1

# AI Image Generation

This skill guides you on how to generate and edit images using the AI image generation service, helping users create high-quality product images, modify existing images, and perform creative visual transformations.

## Core Concepts

The AI Image Generation tool produces new images based on a text prompt and optional reference images. It supports a wide range of use cases:

- **Text-to-image**: Generate a brand-new image purely from a text description.
- **Image-to-image**: Provide one or more reference images and a prompt to generate a new image that preserves elements from the references.
- **Image editing**: Modify specific elements, colors, backgrounds, or styles in an existing image.
- **Product compositing**: Place a product from one image into a scene from another image.
- **Model swapping**: Replace the model or mannequin in a product photo.

**Reference images are strongly recommended** when the user wants the output to closely resemble an existing product or scene. Up to 3 reference image URLs can be provided, separated by commas.

## Parameter Guide

| Parameter | Required | Description | Default |
|-----------|----------|-------------|---------|
| prompt | Yes | Text description of the desired image. Supports text-to-image, image-to-image, editing, model swapping, and more. Max 1000 characters. | -- |
| referenceImageUrl | No | URL(s) of reference image(s). Separate multiple URLs with commas. Up to 3 images supported. Max 1000 characters. | -- |
| aspectRatio | No | Aspect ratio of the output image. | 1:1 |

### Supported Aspect Ratios

| Value | Description |
|-------|-------------|
| 1:1 | Square (default) |
| 3:4 | Portrait |
| 4:3 | Landscape |
| 9:16 | Vertical fullscreen |
