netease_play_playlist

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

The annotations already declare readOnlyHint=false, destructiveHint=false, and openWorldHint=true, so the description's main added value is the start-playback side effect. However, it never says whether an existing queue is replaced or appended to, whether the current track is interrupted, or that requestId is an idempotency key — details an agent needs before firing a state-changing playback call.

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?

One short sentence with the action front-loaded and zero filler, which is good structure. But the brevity is achieved by omitting information rather than by discipline, leaving it under-specified for a 3-parameter mutation.

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?

No output schema and no parameter descriptions in the schema, so the description carries the full explanatory load — and it delivers a single clause. For a state-changing playback tool with queue semantics and an idempotency-looking requestId, this is not enough to invoke confidently.

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% for all three parameters, so the description must compensate and it does not. It only implicitly identifies playlistId; neither the mode enum (sequence/shuffle/repeat_one) nor its default, nor the purpose of requestId, is explained anywhere.

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 names a specific verb+resource pair: build a queue from the given playlist (指定歌单) and start playback. That clearly separates it from single-track playback or state commands like netease_pause/netease_seek. It doesn't explicitly contrast with the other collection-playing siblings (netease_play_liked, netease_play_daily, netease_play_hot_chart), so it stops short of a 5.

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 about when to choose this tool versus netease_play_liked, netease_play_daily, netease_play_hot_chart, or netease_queue. The agent must infer from the name that this is the 'arbitrary playlistId' variant. No preconditions, no exclusions.

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