Scored across 3 tools
Each tool has a clearly distinct purpose: list_models for available model IDs, generate_image for text-to-image, and edit_image for image editing/combining with references. Descriptions are precise, leaving no ambiguity.
All tool names follow a consistent verb_noun pattern: list_models, generate_image, edit_image. This makes the API predictable and easy to navigate.
With 3 tools, the server is appropriately scoped for image generation and editing. Each tool covers a distinct step in the workflow, and no excessive or redundant tools exist.
The tool set covers the full lifecycle: discovering models, generating images from scratch, and editing/combining existing images. No critical operations are missing for the stated purpose.
