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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and destructiveHint, covering the safety profile. The description adds the source URL and return type (pandas.DataFrame), but offers no additional behavioral traits such as pagination, rate limits, or error handling, which is acceptable given the strong 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 brief but unstructured, mixing a title, URL, and docstring fragments. The title repeats the annotation's title, which is redundant. It is not verbose, but the fragmented structure prevents it from being a clean, purpose-built description.

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 description is incomplete for a data-retrieval tool with no output schema. It states the return type but not the actual contents or columns of '每日统计' (daily statistics). There is no information about date range behavior, data granularity, or limitations, leaving significant ambiguity.

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 parameter 'date' with no description coverage. The description adds the semantic meaning '交易日' (trading day), which is useful but does not specify the expected format beyond the default value's hint (YYYYMMDD). It partially compensates for the low schema coverage.

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 as Shanghai Stock Exchange stock options daily statistics, and the URL provides a source hint. However, it lacks an explicit verb (e.g., 'get', 'fetch') and does not distinguish from sibling tools like option_daily_stats_szse, so it doesn't fully meet the top criterion.

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 on when to use this tool versus alternatives. The description merely states the resource and parameters, with no context about selection criteria, prerequisites, or exclusions compared to other option data tools.

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