Each tool has a largely distinct role: doctor is health-check, list_voices is discovery, search_footage is preview, generate_voiceover is an audio artifact, and make_short_video is the full pipeline. The only soft overlap is that make_short_video internally performs voiceover and footage steps, so an agent must infer that the single-purpose tools are building blocks or previews rather than alternatives — the descriptions clarify this, but only after reading.

Four of five names follow a clean verb_noun pattern (make_short_video, generate_voiceover, list_voices, search_footage). 'doctor' is a bare noun that breaks the convention, though it is a recognizable idiom for a diagnostics command.

Five tools is well-scoped for a video-generation server: one diagnostics, one orchestrator, and three focused helpers. Nothing feels padded or redundant.

The core lifecycle — check environment, pick voice, generate audio, scout footage, render video — is covered with no true dead ends. Minor gaps: search_footage only previews with no standalone download tool, and there is no way to list or supply background music, validate a script, or generate audio from an existing file.
