vibo_get_playlist_songs

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description adds the context 'connected-service playlists' indicating a dependency on external service connection, which is useful beyond the annotation's readOnlyHint. However, it does not disclose what happens if the connection is missing or the resource is invalid. The annotation already covers readOnlyHint, so the bar is lower.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Single sentence, front-loaded with key information. No wasted words. Efficient and clear.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the simple list operation and full schema documentation, the description covers the essentials. However, it does not mention return format or pagination behavior (though skip/limit are documented in schema). Lacks completeness for a tool with no output schema.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, with all parameters described (skip, limit, source, playlistId). The description does not add any new meaning beyond what the schema already provides, so baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool lists tracks from connected-service playlists, with a specific verb 'List' and resource 'tracks in one of your connected-service playlists.' It is distinct from siblings like vibo_get_playlists (which lists playlists) and vibo_get_section_songs (which lists songs in a section), but does not explicitly differentiate.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. For example, it does not mention that this retrieves songs from external services like Spotify or Apple Music, while vibo_get_section_songs retrieves from internal sections. No exclusions or context cues.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
