music_list_playlist_tracks

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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds useful behavioral context by noting 'current order' (implying playlist ordering) and 'opaque pagination' (indicating cursor-based, not page-number-based pagination), which goes beyond the structured annotations.

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?

The description is a single, well-structured sentence with no redundant information. It front-loads the core purpose and includes a key detail (opaque pagination) without fluff.

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?

The tool has a bare schema (no descriptions) and 4 parameters, yet the description only addresses the 'cursor' behavior. The 'fields' parameter is entirely unexplained, and while the output schema exists, the description leaves significant gaps for a list operation with multiple optional parameters.

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?

With 0% schema description coverage, the description was expected to compensate, but it only hints at cursor via 'opaque pagination'. It does not explain the 'limit', 'fields', or even explicitly identify 'playlist_id' as required, leaving most parameter semantics unexplained.

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 uses a specific verb ('List') and resource ('playlist's tracks') with a clear scope ('in current order with opaque pagination'), effectively distinguishing this from sibling tools like music_list_playlists and music_get_tracks.

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?

The description clearly implies a use case (retrieving tracks of a playlist), but it does not explicitly state when to use this tool over alternatives (e.g., music_get_playlist or music_search_tracks), nor does it mention exclusions or conditions.

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