netease_playlist_tracks

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The only behavioral detail the description adds is 'paginated', which is already evident from the limit/offset parameters in the schema, so it contributes almost nothing beyond structured data.

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 eight-character description is front-loaded and free of waste, but the brevity reflects under-specification rather than efficient communication. There is room for a sentence of routing or parameter context without bloat.

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?

With three undocumented parameters, no output schema, and no return-shape or pagination-boundary information, the definition leaves the agent guessing about anything beyond the basic intent. For a paginated list tool this is materially incomplete.

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 description coverage is 0% across all three parameters, so the description carries the full burden of explaining playlistId format and the meaning of limit/offset. It only hints that pagination exists and adds no semantics for any parameter.

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 states a specific verb and resource ('分页读取歌单歌曲' – paginated read of playlist tracks), which is clearly distinguishable from siblings like netease_playlists (list playlists) and netease_play_playlist (start playback). It does not, however, explicitly name or contrast with any sibling tool.

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?

There is no guidance on when to use this tool versus alternatives such as netease_playlist, netease_play_playlist, or netease_liked_songs. The agent must infer from the name alone that this is a metadata-reading operation rather than a playback trigger.

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