A straightforward wrapper around OpenRouter's Gemini 3 Pro Image model that handles the API calls and file management for you. Takes text prompts and optional input images, outputs PNG files with proper path handling and multi-image support. The resolution options (1K/2K/4K) and system prompt customization via assets/SYSTEM_TEMPLATE give you decent control without complexity. Error handling covers the usual suspects like missing API keys and rate limits. Good for when you need programmatic image generation in Claude workflows without manually wrestling with OpenRouter's API or figuring out base64 encoding.
