Generate or edit images using AI models (FLUX, Gemini). Use for general-purpose image generation including photos, illustrations, artwork, visual assets, concept art, and any image that isn't a technical diagram or schematic. For flowcharts, circuits, pathways, and technical diagrams, use the scientific-schematics skill instead.

.claude/skills/generate-image/# Generate Image Generate and edit high-quality images using OpenRouter's image generation models including FLUX.2 Pro and Gemini 3 Pro. ## When to Use This Skill **Use generate-image for:** - Photos and photorealistic images - Artistic illustrations and artwork - Concept art and visual concepts - Visual assets for presentations or documents - Image editing and modifications - Any general-purpose image generation needs **Use scientific-schematics instead for:** - Flowcharts and process diagrams - Circuit diagrams and electrical schematics - Biological pathways and signaling cascades - System architecture diagrams - CONSORT diagrams and methodology flowcharts - Any technical/schematic diagrams ## Quick Start Use the `scripts/generate_image.py` script to generate or edit images: ```bash # Generate a new image python scripts/generate_image.py "A beautiful sunset over mountains" # Edit an existing image python scripts/generate_image.py "Make the sky purple" --input photo.jpg ``` This generates/edits an image and saves it as `generated_image.png` in the current directory. ## API Key Setup **CRITICAL**: The script requires an OpenRouter API key. Before running, check if the user has configured their API key: 1. Look for a `.env` file in the project directory or parent directories 2. Check for `OPENROUTER_API_KEY=<key>` in the `.env` file 3. If not found, inform the user they need to: - Create a `.env` file with `OPENROUTER_API_KEY=your-api-key-here` - Or set the environment variable: `export OPENROUTER_API_KEY=your-api-key-here` - Get an API key from: https://openrouter.ai/keys The script will automatically detect the `.env` file and provide clear error messages if the API key is missing. ## Model Selection **Default model**: `google/gemini-3-pro-image-preview` (high quality, recommended) **Available models for generation and editing**: - `google/gemini-3-pro-image-preview` - High quality, supports generation + editing - `black-forest-labs/flux.2-
