Each tool targets a distinct action: searching, generating a single-seed radio, creating a playlist from that radio, generating a multi-seed radio, creating a playlist from a multi-seed radio, and resuming an existing playlist. Though some tools pair as get/create for the same seed type, the names and intended step in the workflow are clear.

All tools follow a consistent snake_case verb_noun pattern: search_songs, get_song_radio, create_private_radio_playlist, get_multi_seed_radio, create_private_multi_seed_radio_playlist, resume_private_playlist. The prefix clearly distinguishes action and the noun hierarchy is logical.

Six tools are well-scoped for a YouTube Music radio playlist server. There are enough tools to cover the basic discovery and playlist creation flow without overwhelming the agent, and each tool contributes a meaningful operation.

The surface covers search, radio creation (single and multi-seed), playlist creation from both, and resuming a saved track plan, which supports the core workflow end-to-end. Minor gaps exist—such as no explicit update or delete playlist operations—but they are outside the apparent main purpose and can be worked around by re-creating.
