Each tool targets a clearly distinct action: authentication (login), pricing lookup (check_pricing), task submission for three different video operations, and task polling (get_task). Although upscale_video, extend_video, and text_to_video all wrap the same RunAPI task-creation mechanism, their names and descriptions make the operation each performs unambiguous.

The set predominantly follows a snake_case verb_noun pattern (upscale_video, extend_video, text_to_video, get_task, check_pricing). The bare 'login' verb is a minor deviation but still readable and conventional for auth.

Six tools is a well-scoped set for a single-model video generation wrapper, with each tool earning its place (auth, three generation modes, task status, pricing). Nothing feels redundant or missing at the count level.

Core lifecycle is covered: authenticate, submit a task, and poll its status/result. Minor gaps exist, such as no task listing/cancellation and no image-to-video variant if the model line supports it, but agents can work around these using get_task and the returned output URLs.
