## What it does

\`imagen` takes a description of the image you want and calls the `gemini-3-pro-image-preview` model to produce it. The result lands on disk as a PNG. Default output is the current directory, though you can pass an explicit path.

The whole thing is one Python script, `scripts/generate_image.py`. It accepts a `--size` flag, for instance `2K`. No pip install is involved — the script relies on the standard library, so Python 3.6+ is enough. Windows, macOS and Linux all work.

You do need `GEMINI_API_KEY` set in your environment before the first run. Without it the script never reaches the generation step, so sort the key out first. The skill fires on its own whenever a task involves making an image; no manual invocation required.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add sanjay3290/ai-skills --skill imagen -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add sanjay3290/ai-skills --skill imagen -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add sanjay3290/ai-skills --skill imagen -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install sanjay3290/ai-skills imagen
```

2. **Manually: put the files in place**
- File: `.github/skills/imagen/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add sanjay3290/ai-skills --skill imagen -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/sanjay3290/ai-skills --path skills/imagen
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add sanjay3290/ai-skills --skill imagen -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/sanjay3290/ai-skills/tree/HEAD/skills/imagen/SKILL.md

## When to use it
- generate placeholder images for a layout before final assets arrive
- produce an app icon or logo from a written description
- draw an architecture diagram for a README
- get a hero image for a landing page
- create an avatar for a profile component

## Example prompts
- Generate an abstract tech hero image for my landing page and save it to ./assets/hero.png
- Create a diagram showing microservices architecture for the README
- Generate a placeholder avatar image for the user profile component

# Imagen - AI Image Generation Skill

## Overview

This skill generates images using Google Gemini's image generation model (`gemini-3-pro-image-preview`). It enables seamless image creation during any Claude Code session - whether you're building frontend UIs, creating documentation, or need visual representations of concepts.

**Cross-Platform**: Works on Windows, macOS, and Linux.

## When to Use This Skill

Automatically activate this skill when:
- User requests image generation (e.g., "generate an image of...", "create a picture...")
- Frontend development requires placeholder or actual images
- Documentation needs illustrations or diagrams
- Visualizing concepts, architectures, or ideas
- Creating icons, logos, or UI assets
- Any task where an AI-generated image would be helpful

## How It Works

1. Takes a text prompt describing the desired image
2. Calls Google Gemini API with image generation configuration
3. Saves the generated image to a specified location (defaults to current directory)
4. Returns the file path for use in your project

## Usage

### Python (Cross-Platform - Recommended)

```bash
# Basic usage
python scripts/generate_image.py "A futuristic city skyline at sunset"

# With custom output path
python scripts/generate_image.py "A minimalist app icon for a music player" "./assets/icons/music-icon.png"

# With custom size
python scripts/generate_image.py --size 2K "High resolution landscape" "./wallpaper.png"
```

## Requirements

- `GEMINI_API_KEY` environment variable must be set
- Python 3.6+ (uses standard library only, no pip install needed)

## Output

Generated images are saved as PNG files. The script returns:
- Success: Path to the generated image
- Failure: Error message with details

## Examples

### Frontend Development
```
User: "I need a hero image for my landing page - something abstract and tech-focused"
-> Generates and saves image, provides path for use in HTML/CSS
```

### Documentation
```
User: "Create a diagram showing microservices architecture"
-> Generates visual representation, ready for README or docs
```

### UI Assets
```
User: "Generate a placeholder avatar image for the user profile component"
-> Creates image in appropriate size for component use
```
