| name | generate-image |
| description | 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 is not a technical diagram or schematic. For flowcharts, circuits, pathways, and technical diagrams, use the scientific-schematics skill instead. |

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:
python scripts/generate_image.py "A beautiful sunset over mountains"
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:
- Look for a
.env file in the project directory or parent directories
- Check for
OPENROUTER_API_KEY=<key> in the .env file
- 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.
