getRecentlyPlayListByUserId

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the action (get) and does not mention read-only safety, authentication requirements, rate limits, or any side effects. While '获取' implies a read operation, the lack of explicit safety or context disclosure 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, concise sentence that is front-loaded with the verb and resource. It contains no fluff or redundancy, earning high marks for efficiency.

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 no output schema and no annotations, but the description provides the essential purpose. However, it lacks details about the return format, pagination behavior, or any constraints beyond what the schema already defines. This leaves some gaps for a complete understanding.

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?

The input schema covers all three parameters with descriptions (userId, offset, limit) providing 100% coverage. The description adds no additional parameter semantics beyond what the schema already states, so the baseline score of 3 applies.

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's function: using a user ID to fetch the recently played list from the Shendao platform. The verb '获取' (get) and resource '最近游玩列表' (recently played list) precisely define its purpose, differentiating it from siblings like getMapInfoByUserId or getFavoriteListByUserId.

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 implies usage for retrieving recent play data via user ID but provides no explicit guidance on when to choose this tool over sibling tools. There are no stated exclusions or alternative recommendations, leaving the agent to infer from the name and context.

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