Each tool has a clearly distinct role: list_models discovers model ids, generate_video starts a paid render, and fetch_video recovers an already-started operation. The descriptions explicitly distinguish starting a new render from fetching an existing one.

All three tools follow a consistent snake_case verb_noun pattern: list_models, generate_video, fetch_video. There is no mixing of conventions or vague standalone verbs.

Three tools is a tight, well-scoped surface for a video-generation server: discovery, generation, and recovery are each covered without redundancy. No tool feels extraneous.

The core workflow is covered: list available models, generate text/image-to-video, and fetch a video from a started operation. Minor gaps exist around operation management, such as checking status without fetching or cancelling a render, but these are not critical for the stated use case.
