analyze_youtube bundles downloading, audio feature extraction, lyrics fetching, and visualization, so its scope overlaps with download_audio and get_lyrics. search_lyrics and get_lyrics are reasonably distinct but rely on the agent infering LRCLIB search-vs-get semantics. Overall, the one-stop analysis tool blurs boundaries.
Four tools follow a clear verb_object pattern: analyze_youtube, download_audio, get_lyrics, search_lyrics. ping is a minor deviation but is a conventional health-check exception. Names are otherwise predictable and readable.
Five tools is a tight, focused set for a YouTube audio and lyrics utility. Each tool has a functional reason to exist, and the count avoids both bloat and thinness.
The core workflow of downloading YouTube audio, analyzing it, and retrieving lyrics is covered without dead ends. Niche operations like analyzing an already-local file or listing past analyses are missing, but agents can work around these gaps.
