Each tool targets a clearly distinct action: account-level status, image generation, image editing, and backend/limits status. There is no meaningful overlap that would confuse an agent.

Names are consistently snake_case and readable, but there is a slight pattern split: generate_image and edit_image follow verb_noun, while codex_account_status and imagegen_status are noun_status. This is a minor deviation rather than a serious inconsistency.

Four tools is well-scoped for a focused Codex/imagegen integration. Each tool covers a necessary function without redundancy or bloat.

The core workflows of generating images, editing images, and checking both account and backend status are covered. Minor gaps like listing or deleting generated images exist, but they are not central to the apparent purpose.
