TDQS
Scored across 4 tools
Each tool targets a distinct image operation: generating from scratch, editing, composing multiple images, and style transfer. No overlap in functionality.
All tool names follow a consistent verb_noun pattern with snake_case (e.g., compose_images, edit_image). No deviations.
Four tools cover essential image generation capabilities without being sparse or overloaded. The scope is well-balanced.
Core image workflows (generation, editing, composition, style transfer) are covered. Minor gaps like cropping or deletion exist but are non-essential for the server's purpose.
