Each tool targets a distinct step: account status (credits), model discovery (list/get), cost estimation, generation, and task tracking (list/get). The list/get pairs are standard and clearly separable, and estimate_generation vs account_status are distinguished by purpose (per-request quote vs overall balance).

Six of seven tools follow a clean verb_noun convention (list_models, get_model, estimate_generation, generate_video, list_tasks, get_task). account_status breaks the pattern as a bare noun phrase, a minor deviation but still readable and consistent with the domain.

Seven tools map to a complete, well-scoped workflow (credits -> model options -> estimate -> generate -> poll). No tool feels redundant or unnecessary for the stated purpose.

The core lifecycle from credit check through generation to download URL is fully covered, including pre-flight estimation and requestId-based retry guidance. Minor gaps exist around task lifecycle management (e.g., cancel/delete a task) that agents cannot perform.
