getMapPlayerStatList

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

With no annotations, the description carries full burden for behavioral disclosure. It mentions authentication needs (Token and userAgent), but this merely repeats the schema. It does not state whether the operation is read-only, what data is returned, or any side effects. The absence of additional behavioral context is a significant gap.

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, focused sentence with no wasted words. It conveys the core purpose and required inputs efficiently, though it is slightly under-specified, which is not a conciseness failure.

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 5 required parameters, no output schema, and no annotations. A single sentence of description is insufficient to understand the return format, pagination, or exact meaning of 'player statistics'. The schema partially covers parameters, but overall context is lacking for an agent to invoke this tool correctly.

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%, and parameter descriptions already explain the purpose of each field (e.g., startTime with example date). The description adds no new semantic meaning beyond the schema, so the baseline of 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 states it retrieves player statistics for a map on the Shendao platform ('获取神岛平台用户地图玩家统计'), which is a clear verb+resource combination. However, it does not differentiate from sibling tools like getMapStatList or getMapPlayerBehavior, so it lacks sibling differentiation.

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 only lists required inputs ('需Token和用户请求头和地图ID') and does not explain when to use this tool versus alternatives like getMapStatList or getMapPlayerRetention. No explicit context or exclusions are provided.

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