Each tool has a clearly distinct role: three distinct image-generation modes (text_to_image, edit_image, remix_image), plus task polling (get_task), auth (login), and pricing (check_pricing). The three generation tools could look similar at a glance, but their mode-specific descriptions make the boundaries unambiguous.

Almost all tools follow a snake_case verb_noun pattern (check_pricing, edit_image, get_task, remix_image), which is predictable and readable. 'login' is a bare verb rather than verb_noun and 'text_to_image' inverts the pattern, but both are still clear and not confusing.

Six tools is well-scoped for an image-generation service: one auth, one pricing lookup, three generation modes, and one task-status retrieval. Each tool earns its place with no redundant or filler entries.

Core lifecycle is covered: authenticate, check cost, create tasks in all three modes, and poll task status with returned output URLs. Minor gaps exist (e.g. list tasks, cancel task), but agents can work around them since task ids and outputs are returned directly.
