The three tools have clearly distinct purposes: generate_image creates images, edit_image modifies existing images, and list_image_models enumerates available models. There is no overlap in resource or action, so an agent can easily select the right tool.

All names use consistent snake_case with an imperative verb first: generate_image, edit_image, list_image_models. The pattern is predictable across the set, with only a minor difference in noun length for the listing tool.

Three tools is a focused, reasonable size for an image-generation server, and each tool earns its place. It is slightly thin compared to servers that include retrieval or history operations, but not problematically so.

The set covers the core lifecycle: generating images, editing them, and discovering available models. Minor gaps exist, such as no explicit retrieval or deletion of generated images, but the primary workflows are supported.
