The core lifecycle is cleanly split: list_models, estimate_cost, generate_video, compare_videos, and resume_video each target a distinct step, and descriptions explicitly clarify boundaries (e.g. resume_video 'nothing new is submitted'). The weak points are storyboard, whose one-line description doesn't make clear how it relates to generation, and the implicit link between 'check the original task' in generate_video and resume_video, which an agent must infer.

Six of seven tools follow a clean verb_noun snake_case pattern (list_models, estimate_cost, generate_video, compare_videos, check_key, resume_video). The exception is 'storyboard', a bare noun that breaks the pattern and, combined with its terse description, is the least predictable name in the set.

Seven tools is well within the sweet spot for a focused media-generation server, and each one maps to a real workflow step (discover, price, generate, compare, batch, resume). No tool looks like filler.

The surface covers discovery, pricing, single generation, multi-model comparison, batch scripting, and retrieval of past tasks. Gaps remain around task management: there is no list/history tool to find prior task IDs and no cancel or delete operation, so agents that lose a task ID have no recovery path.
