Generate Image

This wraps OpenRouter's FLUX and Gemini models for image generation and editing directly from the command line. You pass a prompt and get a PNG back, or feed it an existing image with editing instructions. The docs are clear about when to use this versus the scientific-schematics skill, which matters since you don't want FLUX trying to render your circuit diagrams. It handles the API key setup through dotenv and gives you three model options with actual tradeoffs listed (quality vs speed vs cost). Honestly the most useful part is that it just works as a simple Python script you can drop into any project that needs visual assets without setting up a whole generation pipeline.

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:

# 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.
