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

With no annotations, the description must disclose behavioral traits, but it only mentions cost and free tier. It does not explain what happens if the land ID is invalid, rate limits beyond the free tier, or any side effects. This is insufficient for an agent to understand tool behavior.

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 extremely short, consisting only of a tag line, pricing, and API URL. While concise, it sacrifices essential information such as return values, behavior, and usage context. It is under-specified rather than efficiently informative.

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?

Given the complexity of a query tool with no output schema, the description should explain what data is returned (e.g., land details, metadata). It provides no such context. The tool has 2 required parameters, but the description is insufficient for an agent to understand the tool's capabilities and output.

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 has 100% coverage with Chinese descriptions of each parameter. The description does not add any additional meaning beyond the schema; it only restates the category. The param descriptions are basic (e.g., '平台名' for platform name) and lack details like allowed values or formats, which the description fails to supplement.

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 includes '[Gaming] 元宇宙地块查询' which clearly indicates it's a metaverse land query tool. The verb '查询' (query) and resource '地块' (land) are specific, and the [Gaming] tag provides context. However, it does not differentiate from any of the many sibling tools, most of which are unrelated, but the tag helps.

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?

No guidance is provided on when to use this tool versus alternatives. There is no mention of prerequisites, when not to use, or any context like which metaverse platforms are supported. The description only includes pricing and API endpoint.

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