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

Annotations already declare readOnlyHint=true, idempotentHint=true, and destructiveHint=false, covering the safety profile. The description adds the return type (pandas.DataFrame) and source URL but does not disclose any additional behavioral traits such as pagination, rate limits, or data scope.

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 compact and well-structured, using a title, a relevant URL, and standard docstring entries for parameter and return. Every element contributes meaning without unnecessary elaboration.

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 one-parameter read-only tool, the description covers the main points: source, parameter meaning, return type, and a default example via the URL. It does not explain how to obtain valid index codes or the exact columns of the returned DataFrame, but it is largely adequate for the tool's simplicity.

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 a single 'symbol' parameter with no description, and schema description coverage is 0%. The description compensates by explaining that 'symbol' is the index code ('指数代码') with type str, which is essential. However, it lacks format examples or a code list, leaving some ambiguity about accepted values.

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 identifies the tool as retrieving index component stocks ('成分股') from Shenwan Hongyuan Research's index release details, with a specific URL and parameter. The resource is clear, but it lacks an explicit action verb (e.g., 'get' or 'fetch'), and it does not directly compare to sibling tools beyond the source name.

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. The description only includes a parameter docstring and return type; there are no mentions of prerequisites, exclusion criteria, or other related tools.

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