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

Annotations already declare readOnlyHint=true, destructiveHint=false, idempotentHint=true, covering the safety profile. The description adds the source URL and return type (pandas.DataFrame), which is useful context, but doesn't add details like pagination, data freshness, or rate limits. No contradiction with annotations.

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 structured docstring with title, URL, params, and return type. It is compact and front-loaded with the title. The URL adds some noise but doesn't detract significantly from clarity.

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 exists, so the description should clarify what the returned data contains. It only states '指定 sector 和 indicator 的数据' (data for specified sector and indicator), which is vague about columns or content. The title implies stock rankings, but the return semantics are under-specified.

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 0%, so the description must compensate. It lists the allowed values for both market and indicator, providing the necessary enumeration. However, it doesn't explain the semantics of each choice (e.g., difference between 北向 and 沪股通) and uses 'sector' instead of 'market' in the return description, causing slight ambiguity.

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 resource: 东方财富-数据中心-沪深港通持股-个股排行 (Eastmoney Data Center - Stock Connect Holdings - Individual Stock Ranking), making the tool's purpose clear. However, it lacks an explicit verb like 'get' or 'fetch', and doesn't explicitly distinguish from sibling tools, though the name and context are specific.

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, nor any exclusions or prerequisites. The description only lists parameter choices, offering no context on use cases among the many similar stock_* sibling tools.

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