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

Annotations already declare readOnlyHint=true, openWorldHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the source URL and return type (pandas.DataFrame) but does not explain the optional 'cookie' parameter, rate limits, or any auth requirements beyond what the schema hints at.

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 very short and free of redundancy, but it is under-specified—it reads as a docstring stub with just a title, URL, and return type. It lacks narrative structure and is not appropriately sized for the information it should convey.

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?

For a simple read-only tool, the description gives the data source and return type but omits crucial details such as the actual content/structure of the DataFrame, the purpose of the cookie parameter, and any guidance on when to choose this among the many QDII-related siblings. An agent cannot assess suitability adequately.

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 schema has one optional parameter 'cookie' with 0% description coverage, and the tool description does not mention the cookie parameter at all. The description provides no semantic information about when or how to supply a cookie, so the agent is left completely unguided.

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 identifies the data source (Jisilu) and the specific category ('T+0 QDII-欧美市场-商品'), so the tool's purpose of returning commodity QDII data is fairly evident. However, it lacks an explicit verb such as 'fetches' or 'lists', and it does not differentiate among sibling QDII tools beyond the '商品' (commodity) hint in the title.

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 use this tool versus alternatives. The description only provides a title, URL, and return type; it fails to mention any specific use cases, prerequisites, or exclusions relative to similar QDII tools in the sibling list.

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